Installation and Troubleshooting Guide
To perform certain procedures in this document, you must remove the system cover and work inside the system. While working inside the system, do not attempt to service the system except as explained in this guide and elsewhere in your system documentation.
|
Always follow the instructions closely, and ensure that you review all information in "Safety Instructions" in the System Information Guide. |
|
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge. |
This section provides troubleshooting procedures for external devices attached to the system, such as the monitor, keyboard, or mouse. Before you perform any of the procedures, see "Troubleshooting External Connections."
Look and listen during the system's start-up routine for the indications described in Table 5-1.
Table 5-1. Start-Up Routine Indications
Loose or improperly connected cables are the most likely source of problems for the system, monitor, and other peripherals (such as a printer, keyboard, mouse, or other external device). Ensure that all external cables are securely attached to the external connectors on your system. See Figure 2-4 for the back-panel connectors on your system; see Figure 2-2 for the front-panel connectors.

In Figure 5-1, the system covers are open and the bezel is removed to provide an interior view of the system.
Figure 5-1. Inside the System
The system board can accommodate one or two microprocessors. The PCI riser board assembly accommodates up to two PCI expansion cards. Up to four memory modules may be installed on the system board.
The hard-drive bays provide space for up to three 1-inch SCSI hard drives. SCSI hard drives are connected to a SCSI controller on the system board through the SCSI backplane board.
The peripheral bays provide space for an optional 3.5-inch diskette drive and a CD drive.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Two hot-pluggable, redundant power supplies provide power to the system board and internal peripherals.
During an installation or troubleshooting procedure, you may be required to change a jumper. For information about the system board jumpers, see "Jumpers and Connectors."
The front bezel has system status indicators. A lock on the bezel restricts access to the power button, diskette drive, CD drive, hard drive(s), and the interior of the system.
- To remove the bezel, use the system key to unlock the keylock on the bezel, press the tab at each end of the bezel, and then pull the bezel away from the system. See Figure 5-2.
- To replace the front bezel, fit the tabs on the bezel into the corresponding slots in the front panel and lock the keylock.
Figure 5-2. Removing and Replacing the Optional Front Bezel
Two covers on the top of the system provide access to the system board and other internal components.
To open the system covers, perform the following steps:
- Observe the precautions in "Safety FirstFor You and Your System." Also observe the
safety instructions in the System Information Guide.
- Slide the system out of the rack.
- If the front bezel is installed, remove the front bezel. See "Removing and Replacing
the Optional Front Bezel."
- If the optional security screw is installed on the system cover (see Figure 5-3), remove
it now.
Figure 5-3. Opening the System Covers

If the date and time are not correct in the System Setup program, replace the battery. See "Replacing the System Battery" in "Installing System Options."
If the problem is not resolved by replacing the battery, see "Getting Help."
|
NOTE: Some software may cause the system time to speed up or slow down. If the
system seems to operate normally except for the time kept in the System Setup
program, the problem may be caused by software rather than by a defective battery.
|
|
NOTE: If the system is turned off for long periods of time (for weeks or months), the
NVRAM may lose its system configuration information. This situation is caused by a
defective battery.
|
