About This Guide This guide tells you how to set up your Workgroup Server 8550 and connect it to a network. It also provides technical specifications for your server and information about adding internal and external devices to your server.
Who should read this guide This guide is intended for the person who sets up the server and connects it to an existing network. You need to know some details of your existing network in order to choose the appropriate procedures for connecting the server to your network.
If you want to connect external peripheral devices to your server: After you connect the monitor and keyboard to the server, as described in Chapter 1, turn to the appropriate instructions in Chapter 3, then return to Chapter 1. Connect to the network to complete the setup process. See Chapter 2, “Connecting to the Network,” for details. Other reference material In addition to this guide, you may need to consult the following sources of information.
Where to find answers When you have questions about using your server, there are several places you can look for answers. Settin WorkgroguUpp Your Server 8550 Work Administrgratoup Server or’s Guide In this book Use this book to help you set up and expand your server system, and to connect it to a network. Also use this book to check your server’s technical specifications.
1 Setting Up Your Server Setting up your server involves connecting a monitor, mouse, and keyboard, expanding your system to suit your needs, and connecting to the network. First, acquaint yourself with your server’s features, as shown in the next section, “Your Server at a Glance.” Also, be sure to read the section “Security Issues” for important information about protecting your server from unauthorized access.
Your server at a glance The following figure shows the basic components of your Workgroup Server 8550 assembled and connected to a network.

Security issues The Workgroup Server 8550 lets you concentrate valuable or sensitive information on one system that can be physically isolated and more carefully monitored than would be possible if that information were stored on personal computers. Before you set up the server, you may want to consider two measures that you can take to secure the hardware components: physically isolating the system and using a locking cable to secure the system.
By itself, a locking cable cannot prevent unauthorized use of the server, but it can prevent the server (and its peripheral devices if they are also secured by locking cables) from being removed. Installing internal devices If you purchased additional internal drives or expansion cards for your server, install them now (see Chapter 3 for instructions). If you don’t have internal devices to install, go on to the next section, “Connecting a Monitor.
2 Connect the monitor’s power cord to the monitor. On some monitors, the cord is already attached. 3 Plug in the monitor’s power cord to the server or grounded electrical outlet. Monitor power socket Monitor power cord Some power cords are designed to plug into the back of your server. You can also plug the power cord into a grounded electrical outlet (an adapter may be needed).
Connecting the monitor cable After you plug in the monitor’s power cord, connect the monitor cable to the server’s monitor port. To connect the monitor cable: 1 Attach the monitor cable to the monitor. On some monitors, the cable is already attached. 2 Attach the monitor cable to the server’s monitor port. The monitor port is marked with the icon ™. To connect the cable, firmly push it into the connector and then use the thumbscrews to secure the connection.
Connecting the mouse and keyboard You have a choice of several keyboards for your server. The way you connect the mouse and keyboard depends on whether the keyboard has a separate cable or a built-in cable. Connecting a keyboard with a built-in cable 1 Plug the mouse cable into the recessed port on the back of the keyboard. The plug and the port are marked with the ◊ icon symbol. The positions of the port and icon on your keyboard may be different from those pictured.
Connecting a keyboard with a separate cable 1 Plug the mouse cable into the port on either side of the keyboard. ADB icon Most right-handed people prefer to use the mouse with their right hand; most left-handed people prefer to use the mouse with their left hand. Plug the mouse into the port on the side you prefer. The plug and the port are marked with the same icon (◊). Align the icons before you insert the plug. The positions of the port and icon on your keyboard may be different from those pictured.
Plugging in the server To plug in the server: 1 Plug the socket end of the server’s power cord into the recessed power plug (marked with the symbol ≤) on the back of the server. 2 Plug the other end of the power cord into a three-hole grounded outlet or power strip. Choose a power outlet to which you have easy access. WARNING This equipment is intended to be electrically grounded. Your server is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin.
Turning the server on Before turning the server on, make sure it is in its upright position; the Workgroup Server 8550 is not designed to run on its side. To turn on the server for the first time, follow these steps. 1 Turn on the monitor. See the information that came with your monitor for the location of the power switch. On Apple monitors, the power switch has this icon: I. Note: You only need to turn on the monitor once if its power cord is plugged into the server.
4 Check to see what’s on your screen. m If you see a system message on the desktop, as shown in the following figure, your Mac OS is already set up correctly. Click the OK button to dismiss the dialog box. Startup disk icon Mac OS desktop Why the message about your network connection? The Workgroup Server is preset for a connection to an Ethernet network.
m If you see a blinking question mark, you need to install system software on the server’s hard disk. To install the Mac OS, see “Installing System Software” in Chapter 4, “Managing Hard Disks,” of the Workgroup Server Administrator’s Guide.
Turning the server off You need to turn off (shut down) the server to perform the tasks in Chapter 2, “Connecting to the Network.” IMPORTANT Be sure to turn off the server if you need to do any of the following: m move the server m connect other equipment to the server m unplug the server You can turn off the server by pressing the Power button (located at the front of the server) or you can use the Shut Down command.
2 Connecting to the Network The Workgroup Server 8550 contains built-in hardware and software for connecting the server to two types of networks: LocalTalk and Ethernet. With the appropriate Peripheral Component Interconnect (PCI) card and software, you can also connect your server to additional networks, including other network types, such as Token Ring, Integrated Services Digital Network (ISDN), Fiber Distributed Data Interface (FDDI), and Fast Ethernet (100BASE-T) networks.
Connecting to an Ethernet network The built-in Ethernet capabilities of your Workgroup Server 8550 allow you to connect to any standard Ethernet network using thin coaxial (or “coax”), 10BASE-T twisted-pair, or thick coaxial cables; fiber-optic media; or other standard Ethernet cables. You can connect your server directly to an Ethernet network using a 10BASE-T twisted-pair cable.
Connecting to twisted-pair Ethernet Follow this procedure to connect the server to a network that implements Ethernet over twisted-pair cable. The hardware connection requires a twistedpair patch cord with an RJ-45 telephone-style connector jack. You plug the patch cord into a standard wall plate that is connected to a centralized 10BASE-T hub. To connect the server to a twisted-pair network: 1 Make sure that the server is turned off.
Connecting to thin coaxial Ethernet Follow this procedure to connect the server to an Ethernet network that uses thin coaxial cable. The hardware connection requires an Apple (or Applecompatible) thin coaxial transceiver and a thin coaxial cable. To connect the server to a thin coaxial network: 1 Make sure that the server is turned off. 2 Attach one end of a thin coaxial cable to one of the posts on the thin coaxial transceiver.
Connecting to other types of Ethernet The Apple Ethernet AUI Adapter is a universal adapter that lets you connect the server to less-common types of industry-standard Ethernet media, such as thick coaxial or fiber-optic cable. If you are using the Apple Ethernet AUI Adapter, you also need an Ethernet transceiver for your specific media type, and the transceiver must have a standard AUI port on it.
Connecting to a LocalTalk network To connect your server to a LocalTalk network, you will need LocalTalk cables and a LocalTalk adapter. The Apple LocalTalk Locking Connector Kit DIN-8, available from your Apple-authorized dealer, contains the components you need to connect the server to an existing LocalTalk network by means of the printer port. Printer port icon Printer port To connect the server to a LocalTalk network: 1 Make sure that the server is turned off.
Now that you have made the server’s physical connection to LocalTalk, you can start up the server. IMPORTANT After connecting to a LocalTalk network (if you have not also connected to Ethernet), each time you start up the server you’ll see a dialog box that indicates an error condition. This dialog box informs you that the system has made a temporary switch from EtherTalk (its preset network software connection) to LocalTalk.
Creating a high-performance Ethernet segment You can increase performance in Ethernet networks by creating subnetworks of devices connected by 10BASE-T Ethernet hubs (repeaters that regenerate signals from one device to another). The Apple Ethernet 10T/5 Workgroup Hub provides a modular, plug-and-play approach to creating and expanding high-performance Ethernet networks.
Using multiple network segments By installing additional PCI network cards (and associated software), you can connect your server to a variety of networks. To use more than one network segment at the same time, you will also need network server software that supports multihoming on PCI-based systems (such as AppleShare 4.2.1).
Setting up multihoming Follow these steps to set up multihoming capabilities on your server: 1 Install PCI network cards (and associated software) for additional network segments that you want to connect to your server. Follow the instructions in Chapter 3 of this setup guide. Note: This step is optional, as you can take advantage of multihoming capabilities even when network segments are connected only to the built-in LocalTalk and Ethernet ports on your server.
Have users select the server in their own zone If network segments connected to your server are connected to each other through routers, users will see the server in all the connected zones (in the Chooser). For best performance, make sure that users select in the Chooser the server that resides in the same zone as their own computer. For instance, in the following illustration, users will be able to see the Archives server in Zones 1, 2, 3 and 4.
3 Expanding Your Server and Connecting Other Equipment You can expand the capabilities of your server by installing items internally and by connecting external devices. The following figure shows you the location of the Workgroup Server 8550’s internal components. An external view of the server, depicting the ports to which you connect other devices, is shown in the section “Your Server at a Glance” in Chapter 1.
Opening the server safely WARNING The components in your server, as well as the internal devices that you may install in your server, are very susceptible to damage from electrostatic discharge. When opening your server and while installing internal devices in the server, it is very important to take precautions to protect the server’s components from static electricity damage.
3 Loosen the four large screws at the corners of the back panel. Do not remove the screws or the back panel. 4 Remove the cover from the server. Slide the cover away from the back panel an inch or two. Then raise the cover straight up and off the server.
Installing an expansion card You can install printed circuit boards (called cards) for networking and communications, SCSI acceleration, video and graphics applications, or other purposes. The cards fit into connectors, called expansion slots, inside the server. Your Workgroup Server 8550 has three expansion slots, each designed to accept a Peripheral Component Interconnect (PCI) card. Install only expansion cards that come with Mac OS drivers and are compliant with the PCI 2.0 standard.
Installing a PCI expansion card IMPORTANT Some cards may need to be installed by an Apple-authorized service provider. Check the information that came with the card. Follow these steps to install an expansion card. 1 Carefully follow the instructions provided earlier in this chapter for opening the server safely. Remember to wear a grounded wriststrap while installing an expansion card. 2 Touch the metal part of the power supply case inside the server to discharge static electricity.
3 Lower the retainer. Squeeze the sides of the retainer and pull down. To lower the retainer, squeeze the sides to unlatch it. 4 Being careful not to touch the sharp edges, pull out the metal access port cover behind the expansion slot you want to use, and set the access port cover aside. 1 Press apart the two levers that are next to the card access port to release the access port cover. 2 Slide the access port cover out and away from the access port.
5 To protect your card, touch the metal part of the power supply case to discharge static electricity again, as in step 2, and then remove the card from its static-proof bag. Hold the card by its edges to avoid touching the connector. Connector 6 Align the connector end of the card with the expansion slot. If your expansion card is full-length, be sure that it engages the card guide in the server’s interior.
7 Press the card firmly until the connector is seated. m Slide the card between the two levers that held the access port cover you removed earlier. You may need to press the levers apart slightly to guide the card between them. m Don’t force the card. If you meet a lot of resistance, pull the card out and try again. m To see if the card is properly connected, pull it gently. If it resists and stays in place, it’s connected. (Make sure you don’t pull the card so much that you accidentally disconnect it.
9 Replace the cover on the server. Lower the cover all the way down onto the case. Push the cover toward the back until it touches the back panel. 10 Tighten the screws on the back panel. You are now finished installing the card. If a software driver was included with your expansion card (on a floppy disk), after you finish setting up your server and turn it on, you will need to install the driver.
Upgrading the processor Your server’s processor can be upgraded with the installation of a processor upgrade card. To upgrade the processor, remove the old processor card following the instructions earlier in this chapter for opening the server safely. Then, the new processor card can be installed following the procedure in this chapter for installing expansion cards.
Expanding memory Additional memory can be installed in your server. Memory for your server is provided in packages called Dual Inline Memory Modules (DIMMs). Appendix B, “Technical Information,” describes how much additional memory can be installed in the server. Adding dynamic random-access memory (DRAM) DIMMs increases your server’s memory. The DRAM DIMMs must be the correct type for your server, and can be installed one at a time.
Connecting hard disks and other SCSI devices Your Workgroup Server 8550 has two buses for connecting devices that use the Small Computer System Interface (SCSI, pronounced “skuh-zee”). The SCSI connections permit high-speed communication between the server and the devices. SCSI devices commonly attached to the Workgroup Server 8550 include hard disks, CD-ROM drives, scanners, printers, and tape-backup drives.
Devices on the same SCSI bus must have unique ID numbers (however, devices on different SCSI buses may use the same SCSI ID number).
On the internal/external bus, you can use SCSI ID numbers 0, 4, 5, 6. The secondary hard disk (in the top bay of the internal disk drive bracket), the optional built-in DAT drive (or any other drive in your server’s auxiliary bay), and the built-in CD-ROM drive reserve SCSI IDs 1, 2, and 3, respectively, on the internal/external bus.
Installing an additional hard disk in the internal disk drive bracket You can add a secondary internal hard disk in the top bay of the server’s internal disk drive bracket (shown in the external view of the server in the section “Your Server at a Glance” in Chapter 1). Follow these steps to install an additional internal hard disk. 1 Open the server by following the instructions in the section “Opening the Server Safely” earlier in this chapter.
3 Disconnect the SCSI ribbon cable and power cable from the CD-ROM drive and from any DAT or other drive in the server’s auxiliary bay, and remove the termination block from the end of the SCSI ribbon cable.
4 Disconnect the power cable from the disk drive bracket.
5 Slide the disk drive bracket out and disconnect the SCSI ribbon cable from the bottom drive. To release the bracket, push down the plastic tab just below the bracket. 6 Confirm that the new disk drive is terminated and has its own, unique ID number between 0 and 6. Since the new disk drive your are installing will be the last internal device on the internal/external SCSI bus, you must make sure that the drive is terminated. To terminate the drive, follow the drive manufacturer’s specifications.
7 Slide the new disk drive into the upper bay of the disk drive bracket. Align the connections on the drive with the back of the bracket. 8 Install the four screws in the sides of the bracket and connect the power cable to the upper drive.
9 50 Connect the SCSI ribbon cables to the two drives and slide the disk drive bracket back into place.
10 Reconnect the power cable to the disk drive bracket.
11 52 Reconnect the power cable and the SCSI ribbon cable to the CD-ROM drive and to any DAT or other drive in the server’s auxiliary bay.
12 Replace the cover on the server. Lower the cover all the way down onto the case. Push the cover toward the back until it touches the back panel. 13 Tighten the screws on the back panel. If a software driver was included (on a floppy disk) with your new hard disk, after you finish setting up your server and turn it on, you will need to install the driver. You may also need to initialize the new hard disk.
Installing a drive in the auxiliary bay You can install a digital audio tape (DAT) drive or an additional internal hard disk in your server’s auxiliary bay (shown in the external view of the server in the section “Your Server at a Glance” in Chapter 1). Note: Your server may have come with a DAT drive already installed in the auxiliary bay. Follow these steps to install (or replace) a drive in your server’s auxiliary bay.
3 If you are replacing a DAT or other drive already in the server’s auxiliary bay, disconnect the SCSI ribbon cable and power cable from the drive in the auxiliary bay.
4 If you are replacing a drive, slide the drive out of the bay. 5 Confirm that the new drive has its own, unique ID number between 0 and 6. SCSI ID 2 is recommended for a device in the auxiliary bay. See the section “Setting the SCSI ID Number” earlier in this chapter for details. 6 Check the termination status of the new drive. You do not need to terminate a drive installed in the auxiliary bay.
7 If necessary, attach the new drive to its bracket. Follow the instructions that came with the new drive and bracket. Note: If your new drive did not come with a bracket, see your Appleauthorized dealer for assistance selecting an appropriate bracket for use in the auxiliary bay of your Workgroup Server 8550. 8 Slide the new drive assembly into the auxiliary bay.
9 58 Connect the power cable and the SCSI ribbon cable to the new drive in the auxiliary bay.
10 Replace the cover on the server. Lower the cover all the way down onto the case. Push the cover toward the back until it touches the back panel. 11 Tighten the screws on the back panel. If a software driver was included (on a floppy disk) with your new drive, after you finish setting up your server and turn it on, you will need to install the driver. You may also need to initialize a newly installed hard disk.
Connecting an external SCSI device To connect a SCSI device to the port on your server’s back panel: 1 Make sure that the server and SCSI device are turned off. WARNING Do not connect or disconnect any device while the device or your server is turned on. Doing so could damage the device, your server, or both. 2 Check that the device has its own, unique ID number between 0 and 6. See the section “Setting the SCSI ID Number” earlier in this chapter for details.
4 Make sure that only the last device in the SCSI chain has a terminator and that no other external SCSI device has a terminator. To ensure accurate transmission of information, a terminator must be at each end of a SCSI chain. Some external SCSI devices from manufacturers other than Apple have a built-in terminator. (Check the information that came with the device.) If the device at the end of the SCSI chain does not have a built-in terminator, you need to attach an external terminator.
Installing a device driver A SCSI device driver is software that lets the server communicate with a particular SCSI device. Note: If you have set up your server and connected additional devices, but not yet turned the server on, return to the section “Plugging In the Server” in Chapter 1 before installing a device driver. To install a driver: m Start up your server, if necessary, and drag the driver icon to the System Folder icon on your startup disk.
Connecting a printer Your server has a printer port, which you use to connect a printer to your server. Printer port icon Printer port The printer port accepts either a direct cable connection (to printers such as the StyleWriter II) or a network cable connection (to printers such as a LaserWriter Pro or LaserWriter Select). Follow the instructions that came with your printer when connecting it to your server. A printer can also be connected to the modem port.
Connecting an additional monitor You can use an additional monitor with your server if you install a video expansion card. See “Installing an Expansion Card” earlier in this chapter for instructions. When you connect an additional monitor: m Make sure that the ventilation openings on the server and the monitors are clear and unobstructed. m If necessary, configure the monitor options.
Connecting a modem or GeoPort Telecom Adapter Your server has a port, called the modem port, which is a serial port designed for use with modems and devices such as the GeoPort Telecom Adapter. These devices, when used with appropriate telecommunications software, take advantage of the server’s built-in modem capabilities. The GeoPort Telecom Adapter comes with communications and fax software and can be purchased from Apple-authorized dealers.
About your server’s sound ports The sound input port is marked with an icon of a microphone. The sound output port is marked with an icon of a speaker. Sound input port Sound output port The server’s sound ports accept these 3.5 mm connectors: Stereo miniplug Extended miniplug The smaller connector (a “stereo miniplug”) is found most often on stereo equipment. The slightly longer connector is found on the Apple PlainTalk Microphone and other voice quality microphones.
Connecting most audio equipment To play or record sound with your server, you can attach a microphone, amplifier, tape recorder, headphones, or a pair of speakers. (When you have headphones connected, you don’t hear beeps or other server sounds through the built-in speaker.) For specific instructions on connecting a microphone, skip to the next section, “Connecting and Positioning a Microphone.
Connecting and positioning a microphone With appropriate software, you can use an Apple PlainTalk Microphone (or a compatible line-level microphone) to give spoken commands to your server and to record your voice or other sounds. Apple PlainTalk Microphone Do not use the round omnidirectional microphone supplied with some other Macintosh models. Follow these steps to connect and position the microphone: 1 Shut down the server.
4 Turn on the server. You’re now ready to begin using your microphone. You may want to install software that enables you to give spoken commands to the server, get computer-voice feedback to your spoken commands, and have the server read text to you. For information about installing software on your server, see Chapter 3, “Using Application Software,” in the Workgroup Server Administrator’s Guide.
5 Connect the speakers together with speaker wires, if necessary. Your finished connections should look something like this: - Sound output port Externally powered speakers 6 Audio In port Turn on the server. Now you hear the server’s sound through the external speakers. (You may also need to set options in the Sound & Displays control panel in order to hear sound through your speakers.
Appendix A Safety, Maintenance, and Health Information Important server safety instructions For your own safety and that of your equipment, always take the following precautions. Turn off the server and disconnect the power plug (by pulling the plug, not the cord) if any of the following conditions exists: m The power cord or plug becomes frayed or otherwise damaged. m You spill something into the case. m Your server is exposed to rain or any other excess moisture.
Be sure that you always do the following: m Keep your server away from sources of liquids, such as wash basins, bathtubs, shower stalls, and so on. m Protect your server from dampness or wet weather, such as rain, snow, and so on. m Read all the installation instructions carefully before you plug your server into a wall socket. m Keep these instructions handy for reference by you and others. m Follow all instructions and warnings dealing with your system.
m Turn off your server and all its components before connecting or disconnecting any cables to add or remove any component. Failure to do so could seriously damage your equipment. m Never force a connector into a port. If the connector and port do not join with reasonable ease, they probably don’t match. Make sure that the connector matches the port and that you have positioned the connector correctly in relation to the port.
Handling the keyboard Take care not to spill any liquid on the keyboard. If you do, turn off your server immediately. m If you spill liquid that is thin and clear, unplug the keyboard, turn it upside down to let the liquid drain out, and let it dry for 24 hours at room temperature. If, after you take these steps, the keyboard doesn’t work, take it to an Apple-authorized service provider for repair.
Handling CD-ROM discs Keep these important safety instructions in mind as you use CD-ROM discs: m Hold a disc by the edges or by one edge and the center hole. Do not touch the disc surface. m To clean discs, wipe the shiny surface with a soft damp cloth, working in straight lines from center to edge. Do not use any form of cleaning agent. m To avoid damage to your discs, keep these points in mind: Do not expose discs to direct sunlight. Do not write on discs. Do not spill liquids on discs.
m Keep your computer equipment away from any source of liquid (such as wash basins, bathtubs, and shower stalls). If you drink coffee or other beverages while you’re at your server, take care not to spill. m Avoid exposing your equipment to damp or wet weather. If your system is near a window, be sure the window is closed in rainy weather. The tray on your CD-ROM drive automatically closes when you shut down your server. You may want to open the tray and take out your CD-ROM disc before shutting down.
Power supply The power supply in your server is a high-voltage component and should not be opened for any reason, even when the server is off. If the power supply needs service, contact your Apple-authorized dealer or service provider. Cleaning your equipment Follow these general rules when cleaning the outside of your server and its components: m Use a damp, soft, lint-free cloth to clean the server’s exterior. Avoid getting moisture in any openings. m Don’t use aerosol sprays, solvents, or abrasives.
2 Turn the mouse upside down and turn the plastic ring on the bottom counterclockwise to disengage it. If you have an older mouse, you may need to press the plastic ring (rather than turn it) to disengage it. 3 Turn the mouse right side up with one hand and catch the ring and the ball with your other hand. 4 Clean the three small rollers inside the mouse with a cotton swab moistened with water. Rotate the rollers to clean all around them.
Locking and unlocking the mouse Some mouse devices can be locked so that the ball can’t be removed. A locking mouse has a small hole on the plastic ring. To lock the mouse, follow these steps: 1 Insert a straightened paper clip into the hole on the plastic ring. Insert a straightened paper clip into this hole. (The hole may be located here on your mouse.) 2 Press down on the paper clip while you turn the ring clockwise. Turn the ring a very short distance, until it stops.

(The hole may be located here on your mouse.) 2 Press down on the paper clip while you turn the ring counterclockwise. Turn the ring a very short distance. When the recessed area on the ring is lined up with the recessed area surrounding the ring, the mouse is unlocked.
Health-related information about computer use Muscle soreness, eye fatigue, and other discomforts and injuries sometimes associated with using computers can occur from performing any number of activities. In fact, misuse of the same muscles during multiple activities can create a problem that might not otherwise exist.
RSIs did not suddenly arise when computers were invented; tennis elbow and writer’s cramp, for example, are two RSIs that have been with us for a long time. Although less common than other RSIs, one serious RSI discussed more often today is a wrist problem called carpal tunnel syndrome, which may be aggravated by improper use of computer keyboards. This nerve disorder results from excessive pressure on the median nerve as it passes through the wrist to the hand.
Arranging your office Here are some guidelines for adjusting the furniture in your office to accommodate your physical size and shape. m An adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so that your thighs are horizontal and your feet flat on the floor. The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit your body properly.
m Arrange the monitor so that the top of the screen is slightly below your eye level when you’re sitting at the keyboard. The best distance from your eyes to the screen is up to you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). m Position the monitor to minimize glare and reflections on the screen from overhead lights and windows.

What about electromagnetic emissions? There has been recent public discussion of the possible health effects of prolonged exposure to extremely low frequency (ELF) and very low frequency (VLF) electromagnetic fields. Such fields are associated with electromagnetic sources such as television sets, electrical wiring, and some household appliances—as well as computer monitors. Apple has reviewed scientific reports and sought the counsel of government regulatory agencies and respected health organizations.
Appendix B Technical Information This appendix contains the following technical information about your Workgroup Server 8550: m Expanding your server m Specifications 87
Expanding your Workgroup Server 8550 Your Workgroup Server 8550 was designed to grow with your needs—you can add new capabilities or improve its performance as you wish. You can plug in a number of external devices into its ports. You or your dealer can also install a number of enhancements within the case that houses the computer. However, you must make sure that each component you add is compatible with your server and does not exceed its maximum power allowance.
Specifications This section lists the hardware specifications for the Workgroup Server 8550.
WARNING To avoid damage to your server, Apple Computer recommends that only an Apple-certified technician install additional DIMMs. Consult the service and support information that came with your server for instructions on how to contact an Apple-authorized service provider or Apple for service. If you attempt to install additional DIMMs yourself, any damage you may cause to your equipment will not be covered by the limited warranty on your server.
VRAM configurations VRAM, like standard DRAM, is also provided in DIMMs. Your server comes with 2 MB of VRAM installed in two 1 MB DIMMs. (These DIMMs are installed in bank 1.) Your server’s VRAM can be expanded to a maximum of 4 MB by adding two 1 MB DIMMs to bank 2. Both DIMMs must be added at the same time. IMPORTANT The VRAM DIMMs must be 32-bit-wide, 112-pin fast-paged mode with 70-ns RAM access time or faster. Do not use the 256K or 512K VRAM SIMMs used in older Macintosh computers.
