Specifications Dimension (width x depth x height) • System unit: 194mm x 381 mm x 381 mm Weight • System unit: 10.22kg ( 22.5lb) Environment • Temperature for system unit: - Operating: 10 to 35 C (50 to 95 F) - Non-operating: -10 to 60 C (14 to 140 F) : -20 to 60 C (-4 to 140 F) (Storage package)
Operating Requirements All machines require two power inputs: one for the system unit and one for the monitor display. The system unit comes with a voltage selector switch, allowing selection of voltage of either 115 Vac or 230 Vac. This switch must be in the 230 Vac position when the machine is plugged into a 230 Vac electrical outlet.
Introduction This chapter contains the check procedures used to diagnose the causes of product failures. The diagnostic information consists of: Start: This is the starting point for any diagnostic action. Based on high-level symptoms, the check procedure directs you to more detailed procedures to help resolve machine failures.
Start This is the entry point for all check procedures. The check procedures use failure symptoms, Power-On Self Test (POST) error codes, or beeps to help determine the defective field replaceable unit (FRU). Follow the suggested check procedures or use the diagnostics diskette to determine the problem FRU.

any additional software from the hard disk drive before you reload the software. How to Diagnose Combined FRUs: If an adapter or device consists of more than one FRU, any of the FRUs might cause an error code. Before replacing the device or adapter, remove the FRUs one by one to see if the symptoms change.

Removals and Replacements BEFORE REMOVING ANY FRU, POWER-OFF THE COMPUTER, UNPLUG ALL POWER CORDS FROM ELECTRICAL OUTLETS, THEN DISCONNECT ANY INTERCONNECTING CABLES. ATTENTION: The system board, processors, adapter cards, DIMMs, and upgrade processors can be damaged by electrostatic discharge. Use an electrostatic discharge (ESD) strap to establish personal grounding.
Handling ESD-Sensitive Parts Many electronic parts are sensitive to electrostatic discharge (ESD). To prevent damage when working with ESD-sensitive parts, observe the following instructions. Do these in addition to taking all the usual precautions, such as switching off the power and unplugging the power cord.
Identifying the Parts of the System Unit This computer system has four bays that can hold 5.25-inch and 3.5-inch drives. Additional devices can be installed in the empty bays. Diskette drives in this unit use the standard diskette advanced technology (AT) interface. Hard disk drives in this unit use an integrated drive electronics (IDE) AT interface.
