To open the right panel, the front door must be removed by pushing down on the hinge spring. II.
II. System Components Chassis Circulation System II. Components The circulation system cools the hard disk drives by bringing fresh air in from the side of the server and forcing the hot air out through the back. The server’s air circulation system is comprised of two 3 inch (8 cm) fans mounted in a removable module which brings cool air in from the outside to cool the hard disk drives. Another set of two 2 1/4 inch (6 cm) cooling fans mounted on the chassis, forces the warm air out of the chassis.
II. System Components Rear Cooling Fan Control Board The rear fans are controlled and monitored by a control board. The fan control board requires power input from the power supply which allows the individual fans to obtain their power when connected to the control board. The control board also sends fan status information to the LEDs located on the front of the server and to the ASMA software. The fan control board’s cable connections are shown below. II.
II. System Components Rear Cooling Fan Control Board Settings The rear fan control board has DIP switches to allow controlling the number of fans and the control board. SET2 ON ON ON ON OFF OFF OFF OFF SET3 ON ON OFF OFF ON ON OFF OFF SET4 ON OFF ON OFF ON OFF ON OFF II.
II. System Components Front Cooling Fan Control Board II. Components The front cooling fans’ main purpose is to cool the hard disk drives. These fans also have a fan control board like the rear cooling fans. The front cooling fan module consists of a control board, a hard disk drive LED status board, and two cooling fans. The message LED board mounted in the front of the cooling fan module consists of five sets of LEDs to represent the status of up to five hard disk drives.
II. System Components Fixed Storage Device Tray II. Components Internal fixed storage devices are mounted on removable trays. There are four available, one for a floppy device and another three for full-size devices. There are six screws provided (as circled) for mounting a 4 inch device such as a floppy or hard disk drive. Four screws are provided (as boxed) for mounting a 6 inch device such as a CD-ROM or tape drive.
II. System Components Fixed Storage Devices Floppy Drive and CD-ROM The floppy drive fits in the topmost bay along with the power button. A CDROM can fit into either the second, third, or fourth bay from the top. A metal clip on each side of the device tray secures the tray in place. Press inward to release the clips. The tray slides in or out on the side rails. II. Components Removing a floppy or CD-ROM drive Floppy Drive and Storage Device Spacers Spacers are required for cosmetics only.
II. System Components Hot-Swap Trays II.

II. System Components SCSI Information SCSI Connections II. Components 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 Motherboard Securing Remove the extended expansion card guide before installing or removing the motherboard. All screws are necessary to provide the needed stabilization to support all the motherboard expansion cards used in a server. II. Components Place four spacers in the areas circled on the chassis. spacer Place twelve screws in the areas circled on the motherboard. There is a chassis intrusion connector here.
II. System Components Device Cables II. Components Several cables are used for connecting devices in the server. The following picture points out the name of each cable and its suggested location. Plastic keepers protect the cables from contact with the fans and other devices. Make sure that all cables are properly secured. Floppy Cable IDE Cable (CD-ROM) 68-pin WideSCSI Cables (for RAID card) Plastic Keeper Cables from devices Cable Connections The cables connect to the motherboard as shown.
II. System Components Card-Secure Module The chassis provides an adjustable expansion card securing rack to help hold expansion cards in their slots. The securing rack module is mounted by four screws on the edge of the server . There are 18 knobs on the module. Turn the knob counter clockwise to extend the metal arm under each knob. Keep turning until the arm is firmly press against the expansion card. Turn the knob clockwise to retract the metal arm. II.
II. System Components IDE Cabling Proper IDE device operation requires that the IDE ribbon cable does not exceed 18 inches. If only one IDE device is used, connect it to the end of the cable. Remove unused cables from the motherboard’s IDE connector to ensure proper signal strength. II. Components CD-ROM Disk Drive (IDE) The CD-ROM disk drive mounts only in one of the three fixed device bays and requires signal and power connections like that of IDE hard disk drives.
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 pair of wires are twisted for signal shielding like that of high speed (e.g. category 5) LAN cabling. II.
Female Terminator for SCSI Cable II. Components II. System Components Male Terminator for SCSI board Expansion Cards Expansion cards can be easily installed just like any standard PC computer. Up to 4 PCI or 2 ISA (1 slot is shared allowing a maximum of 5 cards at one time) cards can be installed. One AGP slot is also available for a hardware 3D accelerator with an AGP connector. Expansion Card Installation Procedure: 1. Follow the static precautions described in the front of this manual. 2.
II. System 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. It is normal practice to remove the power cord before opening the side panel. With the power cord removed, you can ensure there are no voltages which can cause shorts while installing or removing internal components. II.
II. System Components Starting the Server II. Components Turn ON the server by pushing the power button. The power button will snap back when released 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.
III. 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 are mounted properly. NOTES: • Narrow refers to 50 pin and Wide refers to 68 pin. Don’t get confused by the width of the connector or cable.
