II. System Components Side Panel The side panel needs to be removed to gain access to the internal system. II. Components Side Panel Side Panel Removal Procedure: 1. Remove the padlock if one is used on the side panel. 2. Remove the thumb screw on the back of the side panel. 3. Pull the side panel away from the chassis from the back. 4. Pull the bottom of the side panel outward from the bottom.
II. System Components Motherboard Mounting Once the stabilizing link bar is removed, you can install or replace the motherboard but note the screw locations. All screws are necessary to provide the needed stabilization to support all the motherboard expansion items. NOTE: The screw locations will vary with different motherboards. II.
II. System Components Front Panel II. Components Front Panel The front panel needs to be removed to install or remove the device cage covers for installing or removing devices mounted in the device cages. You can remove the front panel either in the upright position or flat on its right panel. Lean the front panel over the edge of a table or book if working upright. Reach your fingers up into the front panel and pull the front panel away from the chassis.
II. System Components Air Circulation System The server’s air circulation system is comprised of one 3 inch (8 cm) fan mounted on the inside rear of the chassis and another one mounted on the front of the chassis, as well as the power supply itself. The air circulation system cools the internal system by bringing fresh air in from the back and forcing the hot air out through the front. It is important to keep the air surrounding the hard disk drives below 122˚F (50˚C) to prevent hard disk failures. II.
II. System Components Device Cage (3.5”) The 3.5” device cage is used for mounting one 3.5” floppy device (such as a 1.44MB floppy, LS-120, MO, or ZIP disk drive) and two hard disk drives. Before devices can be installed or removed from the 3.5” device cage, you must remove the device cage from the chassis. II. Components 3.5” Device Cage 3.5” Device Cage Removal Procedure: 1. Remove the stabilizing link bar, if not already removed. 2.
II. System Components Floppy Disk Drive (1.44MB) II. Components Floppy / 5.25 Cage The 1.44MB floppy disk drive requires signal and power connections. The power connection is easy since it only fits one way and a latch is available to secure it when fully inserted. The signal cable is tricky because the cable fits in both orientations as well as shifted one direction or the other. The signal cable also has no latch to determine when full insertion is made.
II. System Components CD-ROM Disk Drive The CD-ROM disk drive mounts only in the 5.25” device cage and requires signal and power connections like that of IDE hard disk drives. The power and signal cable is straightforward with connectors designed to only fit correctly. The red stripe of the signal and power cables should face each other. CD audio output II. Components CD-ROM / Expansion NOTE: A CD-ROM audio cable is also provided in case you install an audio card.
II. System Components SCSI Information SCSI Connections II. Components SCSI Information Your server can support up to 15 user installed single-ended SCSI devices. Be sure to include both internal and external SCSI devices in your device setup. Each SCSI device (both internal and external) must have a unique address (or SCSI ID). Check your SCSI device documentation for instructions. Be sure to record all SCSI addresses so that you can prevent SCSI address conflicts.
II. System Components Hard Disk Drive Mounting Two hard disk drives may be mounted into the 3.5” device cage, a single hard disk drive may be mounted on top of the power supply, and two more may be mounted in the 5.25” device cage using hard disk drive carriages (not provided) designed for use in 5.25” device bays. The exception is Quantum’s Bigfoot IDE hard disk drive which fits in the 5.25” device bays. II.
II. System Components Ultra2 SCSI Disk Drive The Ultra2 SCSI disk drive has separate signal and power connections. The power connector is the same as standard hard disk drive power. The signal cable is different. For proper signal stability in Ultra2 speeds, a special twisted ribbon cable must be used. Each two wires are twisted for signal shielding like that of high speed (e.g. category 5) LAN cabling. II.
II. System Components Device Connections The following picture shows a completed server example with both standard and optional components. Device Cable Connections II. Components Device Connections The cables connect to the motherboard as shown. The motherboard includes onboard SCSI with 68 pin and 50 pin SCSI connectors. The provided 68 pin SCSI cable is designed for Ultra2 SCSI speeds and may be used for both Wide-SCSI and Ultra2-SCSI devices.
II. System Components Power Supply II. Components Power Supply This server has a standard power supply with specifications to meet this server’s motherboard requirements. A clearly marked label gives detailed specifications of the power supply. A power switch is provided to shut off all voltages, including the standby power. Not all ATX power supplies provide a power switch and therefore it is normal practice to remove the power cord before opening the side panel.
II. System Components Starting the Server II. Components Starting / LED Turn on the system unit by turning the power knob clockwise and pushing inwards momentarily. The power button will snap back because ATX power systems have an electrical On/Off switch unlike AT systems which require a permanent On or Off position. If the Power On LED does not light, make sure the power cord is connected to the system unit and to a working grounded outlet.

IV. Appendix SCSI Cable Limits SCSI cables have a limit to the length that it may have. Exceeding the length may cause problems mounting or using any one of the SCSI devices. CAUTION: Exceeding the SCSI cable limits may cause unreliable data transfers even if all the devices mount properly. NOTES: • Narrow refers to 50 pin and Wide refers to 68 pin. Don’t get confused from the width of the connector or cable.
IV. Appendix SCSI Connection Examples This is an example of how SCSI devices can be connected to your server. • • • Two 9GB Ultra2-SCSI hard disks in the 3.5” cage can be connected to the Ultra2 connector on the motherboard for 18GB of main storage. One Ultra-SCSI tape drive in the 5.25” cage is connected to the 50 pin narrow connector on the motherboard for routine backups.
IV. Appendix Glossary Byte (Binary Term) One byte is a group of eight contiguous bits. A byte is used to represent a single alphanumeric character, punctuation mark, or other symbol. COM Port COM is a logical device name used by to designate the computer serial ports. Pointing devices, modems, and infrared modules can be connected to COM ports. Each COM port is configured to use a different IRQ and address assignment.
