Subsystem Monitoring The 24 BAY RAID subsystem comes with several monitoring methods to give you constant updates on the status of the system and individual components. The following monitoring features are included in the subsystem. 1.3.1 I2C bus The following subsystem elements interface to the RAID controller over a non-userserviceable I2C bus: Disk drives (drive failure output) PSU modules Cooling modules Temperature sensors 1.3.
Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual Drive trays (2 LEDs) BBU module (optional FRU; 1 LED) 1.3.3 Firmware and RAIDWatch® GUI Firmware: The firmware (FW) is pre-installed software that is used to configure the subsystem. The FW can be accessed through either the front panel LCD keypad or a terminal emulation program that is installed on an external computer/application server used as a management station.
Chapter 1: Introduction Cooling modules Hard drives BBU module (optional FRU) 1.4.3 Normalized Airflow Proper subsystem cooling is referred to as “normalized” airflow. Normalized ensures the sufficient cooling of the subsystem and is only attained when components are properly installed. Therefore, a failed component should only swapped when a replacement is available. If a failed component is removed replaced, permanent damage to the subsystem can result.
Chapter 2 Hardware Installation 2.1. Installation Overview This chapter gives detailed instructions on how to install the Falcon 24 BAY subsystem. When installing the subsystem, it is necessary to install hard drives, drive trays, and cables. Installation into a rack or cabinet should occur before the hard drives or drive trays are installed into the subsystem.
2.3. Static-free Installation Static electricity can damage the system’s electronic components. Most of the controllers that are returned for repair are the result of improper installation and ESD damage. To prevent ESD damage, follow these precautions before touching or handling any of the components: When installing the subsystem, you should wear an anti-static wrist band or touch a grounded metal surface to discharge any static electricity from your body.
Step 5. Install the drive trays into the enclosure. Note that the drive trays used in single- or redundant-controller subsystems are different. (See Section 0) Step 6. Connect the cables. Use the supplied power cords to connect the subsystem to main power. It is recommended to connect power cords to separate and independent power sources for higher redundancy. Make sure your subsystem is electrically grounded.
Figure 2-1: Installation Procedure Flowchart 2.5. Unpacking the Subsystem The subsystem components are packed in several boxes. WARNING! For a detailed packing list, refer to the included Unpacking List. Do not rely on the non-definitive, summarized checklist shown below--it is for reference only.
Two (2) cooling modules Two (2) front handles One (1) LCD keypad panel on the left side foldable handle Back-end PCBs 2.6. Memory Module Installation 2.6.1 Memory Module Installation Overview The subsystem comes with a pre-installed 256MB DDR RAM DIMM module on each controller. The controller supports memory modules with sizes up to 2GB. If memory modules with a different size need to be used, the pre-installed DIMM module can be removed and the new ones installed.
WARNING! • The controller board in the controller module is a sensitive item. Please ensure that all anti-static precautions stipulated above are strictly adhered to. Only qualified engineers should replace the DIMM module. • Removing the DIMM module while it contains cached data and when the BBU is still attached to the controller can damage the DIMM module. When the controller is removed from chassis, the BBU will start to discharge supplying power to memory.
2.6.3 DIMM Module Installation/Replacement WARNING! 1. Consult the technical support department of your reseller or distributor if you are not sure which memory module can be installed into the controller. 2. The installed BBU and controller module must be removed prior to installing a new memory modules. Do this with care. Sensitive components can be damaged during the process. 3. The BBU module is hot-swappable and can be independently swapped from the controller.
Figure 2-2: Removing the Dummy Cover Figure 2-3: Removing the Controller Module Step 4. Remove the DDR DIMM module. You can access the DIMM module from the opening on the right side of the controller canister. To remove the DIMM module, press the white, plastic ejectors (clips) of the sides of the DIMM socket. Grasp the DIMM module by its edges and pull it out of the socket without touching the electrical components nearby. Place the module in an anti-static bag.
Figure 2-4: Accessing a DIMM Module Step 5. Install the replacement DIMM module. Carefully remove the replacement module from its anti-static bag. Grasp the module by edges. Make sure the white, plastic ejectors on the sides of DIMM socket are open. Carefully align the DIMM module to the socket. Pressing firmly on both ends, push the module into the socket until the ejectors return to the closed position. Step 5. Install the controller and the BBU module (if installed).
Figure 2-5: Installing a BBU Module 2.7. Hard Drive Installation 2.7.1 Hard Drive Installation Overview WARNING! 2.7.2 1. Handle hard drives with extreme care. Hard drives are very delicate. Dropping a drive onto a hard surface (even from a short distance) and hitting or touching the circuits on the drives with your tools may all cause damage to drives. 2. Observe all ESD prevention methods when handling hard drives. 3. Only use screws supplied with the drive canisters.
• Capacity (MB/GB): Use drives with the same capacity. RAID arrays use a “leastcommon-denominator” approach meaning the maximum capacity of each drive in the array is the maximum capacity of the smallest drive. 2.7.3 • Profile: The drive trays and bays of the system are designed for 3.5inch wide x 1-inch high hard drives. • Drive type: The 24 BAY subsystem can use either SATA-II or SATA-I interface hard drives. Drive Installation Step 1. Place the SATA hard drive into the drive tray.
To access drive bays on the left- or right-side column, first flip the retention latches (see Error! Reference source not found.) on the enclosure front handles, and then swing the handles to the left and right-hand sides. To close the handles, see Figure 2-7, first swing the handles towards the center to reveal the retention latch, flip the latch, and then proceed with closing the handles.
Figure 2-9: Drive Tray Front Flap Step 3. Line the drive tray up with the slot in which you wish to insert it. Make sure that it is resting on the rails inside the enclosure. Once the drive tray is lined up with the slot, gently slide it in. This should be done smoothly and gently. Step 4. Close the front flap on the drive tray. Make sure the front flap is closed properly to ensure that the connector at the back of the drive tray is firmly connected to the corresponding connector on the backplane.
Figure 2-11: Drive Tray Key-lock Rotation WARNING! All the drive trays must be installed into the enclosure even if they do not contain a hard drive. If the drive trays are not installed, then the ventilation required for cooling will not be normalized and the subsystem will be irreparably damaged. 2.9. Optional BBU Installation If your order includes an optional BBU, it should be installed before you power on your subsystem.
Figure 2-12: Removing the BBU Module Step 2. Once the dummy cover has been removed from the controller module, unpack the BBU module package. Carefully align and insert the BBU into the module slot and fasten the spring screw to secure the BBU. Once properly installed and after the subsystem is powered on, the status LED on BBU should start blinking, indicating it is charging the batteries inside. Figure 2-13: Installing a BBU Module 2.10.

Chapter 4 Subsystem Connection and Operation Chapter 4 Subsystem Connection and Operation 4.1 SCSI Host Connection Prerequisites This chapter introduces sample topologies, configuration options and server connections for the Falcon subsystems and discusses both the power on and power off procedures.
Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual 4.1.2 SCSI Port on the Controller Rear Panel The subsystem is equipped with two (2) dual-stacked connectors featuring four (4) VHDCIs on the controller faceplate. (See Figure 4-1) Each 68-pin VHDCI connector is specified as “CH # IN” or “CH # OUT” ports. The “In” ports connect to SCSI initiators (host HBAs), and the “Out” ports connect to SCSI targets (expansion enclosures).
Chapter 4 Subsystem Connection and Operation Figure 4-2: Single Host Connection: Correct Connection A server is connected to one of the host ports. There is no need for further termination configuration because the firmware default is “terminator ON,” and the auto-sense terminator is also automatically enabled. Figure 4-3: Dual-Host Connection: Incorrect Connection The “IN” and “OUT” ports are separately connected to a server and a cascaded enclosure.
Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual configuration process can be found in the Generic Operation Manual or the RAIDWatch User s Manual located on the Product Utility CD.

Appendix B Uninterruptible Power Supply Appendix B Uninterruptible Power Supply B.1. Uninterruptible Power Supply Overview An uninterruptible power supply (UPS) is a separately purchased battery backup unit that can be connected to an RAID subsystem. If the UPS is sufficiently large, it can power the whole subsystem in the event of an AC power failure allowing the RAID subsystem to safely distribute the on-going I/O processes onto the hard drives. B.2.
Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual B.4. Connecting the UPS to the Subsystem B.4.1 Connect the PSU Module Power Cords The three (3) power cords shipped with the subsystem must be plugged into the power cord sockets in the rear of the PSU modules. The plug at the other end of the power cord must be inserted into a socket on the UPS. Please refer to the documentation that came with your UPS device to determine the location of these sockets.
Appendix B Uninterruptible Power Supply B.5. Power On When powering on the subsystem, the UPS must be powered on before the subsystem. To see how to power on the UPS, please refer to the documentation that came with your UPS. Note that the power on sequence described in Chapter 4 will be altered. The power on sequence when a UPS is connected is shown below: Step 1. Power on the network connection devices (including FC switches). Bypass this step if you are using a SCSI host subsystem. Step 2.
Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual B.6.1 Normal Operational Status If the UPS is connected to main power and the UPS battery power level is above 50%, then no status messages will appear and the “Write-back” write policy will be applicable. B.6.2 UPS Messages The following messages may appear on the LCD screen: Message 1: “UPS connection is absent” This message appears when COM2 has not been connected to the UPS or an established link is lost.
Appendix B Uninterruptible Power Supply B.6.3 UPS Message Summary The table (Table B-1) below summarizes the UPS messages described above. It is important that you become familiar with these messages and their meanings to help maintain the integrity of the data running through your subsystem.
