This chapter contains information about hardware and specifications for your system.
This chapter does not contain detailed information on the system board. See the System Board Guide delivered with your system for detailed information on the system board and its components, BIOS, memory, slots and sockets, jumpers and connectors, and ports.
Figure 10-1 shows the power and data signals of the base unit components.
The following sections show EIDE and SCSI cable routings and connections to internal peripheral devices, and depicts standard and optional cables used in the system. For detailed information and location of bus connectors on the system board, see the System Board Guide.
 | Caution: When handling cables, flex them as little as possible. Ensure that cables do not contact sharp metal surfaces or become excessively bent or twisted. In particular, SCSI cables should not have any creased bends. |
One EIDE cable connects the primary EIDE channel to the CD-ROM drive and (optionally) to another device in the peripheral device cage. Another EIDE cable can connect the secondary EIDE channel to one or two devices in the peripheral device cage.
In a RAID system:
A SCSI cable connects Channel A of the on-board SCSI controller to the SCSI port on the back of the base unit.
Warning: For continued protection against fire and energy hazards, do not connect an external SCSI port to SCSI Channel B. Connect an external SCSI port only to SCSI Channel A. On some systems, a SCSI cable connects Channel B of the on-board SCSI controller to SCSI devices in and above the peripheral device cage.
A SCSI cable connects the SCSI connector on the RAID controller card to a SCSI connector on the back of the RAID disk drive cage.
In a JBOD ("just a bunch of disks") system:
A SCSI cable connects Channel A of the on-board SCSI controller to SCSI devices in and above the peripheral device cage and to the SCSI port on the back of the base unit.
Warning: For continued protection against fire and energy hazards, do not connect an external SCSI port to SCSI Channel B. Connect an external SCSI port only to SCSI Channel A. A SCSI cable connects Channel B of the on-board SCSI controller to disk drives in the JBOD disk drive cage.

The system has two power supplies for increased power supply reliability. Both must be connected to AC power for the system to operate correctly. However, if one power supply fails, you can replace it without shutting down the other power supply. This hot-swap capability lets you handle a power supply failure without shutting down and powering down the entire system.
Both power supplies provide 350 Watts of power to the system. Each power supply has a manual switch for selecting either 115 V AC (90-132 V AC) range or 230 V AC (180-264 V AC) range for domestic or international locations. The input frequency is 47-63 Hz, single phase. Input current is 6.0 A for the 115 V AC range and 3.5 A for the 230 V AC range. The typical efficiency is 70 percent at maximum output load.
The combined power supplies have the following DC output specifications. .

|---|---|---|---|---|---|---|
Nominal Output Voltages (VDC) | +5.02 | +3.32 | +12.0 | -12.0 | -5.0 | +5.0 |
Maximum Current Rating (ADC) | 30 | 15 | 12 | 0.5 | 0.5 | 1 |
Standby +5.0 VDC output voltage is always on.
Maximum +5.0 V and +3.3 V combined power is 150W.
The combined power supplies have a single power cable, P1 that connects to an ATX power connector on the system board.
The combined power supplies have four peripheral device power cables and one floppy disk drive power cable. Three of the cables have two peripheral device power connectors (P14 and P15) each. The fourth cable has two peripheral device power connectors (P12 and P13) and a floppy disk drive power connector (P11)..

The system has three 12 V DC cooling fans that are controlled by circuitry on the system board. A 120 mm (77 cfm) fan mounted behind the peripheral device cage and two 120 mm (77 cfm) fans mounted behind the disk drive cage ensure proper airflow to cool system components in the base unit. These fans bring cool air into the base unit to force out warm air. Another, smaller fan cools an area of the system board between the processors.
The cooling fans are field replaceable. See Chapter 9, “Servicing the System”for details on replacing the cooling fans.
| Caution: To maintain proper airflow to cool system components, make sure you install a new fan with the label on the fan motor facing toward the back of the base unit. |
Each power supply contains its own cooling fan. The power supply fans are not field replaceable. If a power supply fan requires replacement, you must replace the power supply. See Chapter 9, “Servicing the System” for details on replacing a power supply.
The system features advanced hardware monitoring and power management capabilities. These features help save energy, prolong system life, and provide for functionality such as remote system wakeup.
When used with Hardware Monitor software, these features enable you to keep track of such things as system voltages, component and chassis temperatures, and fan presence and operation. For more information on the items that can be monitored on your system, see the System Board Guide and Hardware Monitor Help.
See the System Board Guide for detailed information on the system board and its components.
