Chapter 10. System Hardware and Specifications
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.
The following diagram shows the power and data signals of the base unit components.
Internal Peripheral CablingThe 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.
|
The installed EIDE cable connects the primary EIDE channel to the CD-ROM drive and to another front-access peripheral device. Another EIDE cable, which can connect the secondary EIDE channel to two front-access peripheral devices, is provided with the system but is not installed.
SCSI cabling in the system is as follows:
A SCSI cable connects Channel A of the on-board SCSI controller to SCSI devices in the peripheral device bay 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 cable connects Channel B of the on-board SCSI controller to SCSI disk drives in the disk drive cage.

The 400 Watt power supply has a manual switch for selecting either 115 VAC (90-132 VAC) range or 230 VAC (180-264 VAC) range for domestic or international locations. The input frequency is 47-63 Hz, single phase. Input current is 8 amps maximum for the 115 VAC range and 4 amps for the 230 VAC range. The power supply has a minimum efficiency of 70 percent at maximum output load. The power supply is enclosed in a case that includes a fan for additional airflow through the system.
The power supply has the following DC output specifications..

Standby +5.0 VDC output voltage is always on.
Maximum +5.0 V and +3.3 V combined power is 300W.
The power supply has two power cables, P1 and P2, that connect to J1 and J2 on the system board.
The power supply has six peripheral device power cables (P3, P4, P5, P6, P7, and P8) and one floppy disk drive power cable (P9). These cables connect in daisy-chains to the power supply and to each other as follows:
Power supply → P3 → P4
Power Supply → P5 → P6
Power supply → P7 → P8 → P9.

The system has three 12 V DC cooling fans that are controlled by circuitry on the system board. A 92 mm (50 cfm) fan mounted behind the peripheral device bay and two 119 mm (77 cfm) fans mounted behind the disk drive cage ensure proper airflow to cool system components in the base unit chassis. All fans bring cool air into the chassis to force out warm air.
The chassis fans are field replaceable. See Chapter 9, “Servicing the System” for details on replacing the chassis fans.
The power supply contains its own cooling fan. The power supply fan is not field replaceable. If the power supply fan requires replacement, you must replace the power supply. See Chapter 9, “Servicing the System” for details on replacing the power supply.
Hardware Monitoring and Power ManagementThe 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.
