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 a Zx10 SystemSCSI cabling in a Zx10 system is as follows:
A cable connects Channel A of the on-board SCSI controller to the external port on the back of the base unit and, in some systems, to front-access SCSI devices. Either the external-only or the internal/external cable is used, but not both.
 | 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 up to three SCSI disk drives.
SCSI Cabling in a Zx10 VE SystemSCSI cabling in a Zx10 VE system is as follows:
A SCSI cable connects Channel A of the on-board SCSI controller to up to three SCSI devices in internal access bays and to the external port on the back of the base unit (below the rear fan).
| 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 up to two SCSI devices in front-access bays and to an internal terminator module.

Different power supplies are used in the different system configurations. The power supply in each system is field replaceable. See Chapter 9, “Servicing the System” for details on replacing the power supply.
The 300 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 7 amps maximum for the 115 VAC range and 3.5 amps for the 230 VAC range. The power supply has a typical efficiency of 70 percent at maximum output load. The power supply is enclosed in a case that includes a fan for additional airflow.
The 300 Watt power supply has the following DC output specifications.

The power supply has two power cables, P1 and P2, that connect to ATX power connectors on the system board.
The power supply has six peripheral device power cables (P3 throughP8) 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 → P5
Power supply → P6 → P7 → P8 → P9

The system has two 92-mm 12 V DC cooling fans that are controlled by circuitry on the system board. The front fan is mounted in a housing at the bottom front of the base unit chassis. The rear fan is mounted to the upper back of the base unit chassis under the system's power supply. Both fans bring cool air into the base unit to force out warm air.
The chassis fans are field replaceable. See Chapter 9, “Servicing the System” for details on replacing the chassis fans.
| Caution: To maintain proper airflow to cool system components, make sure you install a new fan with the airflow arrow pointing into the chassis.
|
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.
