In Figure 5-5, the system covers are removed and the bezel is opened to provide an interior view of the system.
Figure 5-5. Inside the System
The I/O board can accommodate up to 11 PCI expansion cards (10 PCI or PCI-X cards at 64-bit/33100 MHz and one PCI card at 32-bit/33 MHz). The system memory is contained on two separate riser cards that must be populated with at least two memory modules each for the system to operate. The peripheral bay provides space for four additional 1-inch SCSI hard drives or one tape drive.
The hard-drive bays provide space for up to eight 1-inch SCSI hard drives. These hard drives are connected to a RAID controller card through the SCSI backplane board.
The power distribution board (PDB) provides hot-plug logic and power distribution for the system. Your system can utilize an AC module or an optional, integrated, redundant AC power module to provide AC current to the hot-pluggable power supplies. The AC module is used when a redundant AC power source is not required. The integrated redundant AC power module enables your system to use two AC inputs. Your system can operate on either of these inputs and automatically switches from a failing AC power source. The three hot-pluggable power supplies slide into connectors mounted on the PDB and provide power to the system board, SCSI backplane board, and internal peripherals.
For non-SCSI drives such as the diskette drive and CD drive, an interface cable connects the interposer board, attached to the CD/diskette drive tray, to the peripheral riser card. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter on either the I/O riser card or an expansion card (for more information, see "Installing Drives").
During an installation or troubleshooting procedure, you may be required to change a jumper. For information on jumpers, see "Jumpers and Connectors."
The optional systems management applications monitor critical system voltages and temperatures, the system cooling fans, and the status of the SCSI hard drives in the system. Alert messages appear in the alert log window. For information about the alert log window and options, see your systems management software documentation.

- Error message shows a problem with the battery
- System Setup program loses system configuration information
- System date and time do not stay current
The system battery maintains system configuration, date, and time information in a special section of memory when you turn off the system. The operating life of the battery ranges from 2 to 5 years, depending on how you use the system (for example, if you keep the system on most of the time, the battery gets little use and thus lasts longer). You may need to replace the battery if an incorrect time or date is displayed during the boot routine.
You can operate the system without a battery; however, the system configuration information maintained by the battery in NVRAM is erased each time you remove power from the system. Therefore, you must re-enter the system configuration information and reset the options each time the system boots until you replace the battery.
- Re-enter the time and date through the System Setup program (see "Using the System
Setup Program" in the User's Guide for instructions).
- Turn off and disconnect the system from the electrical outlet for a few hours.
- Reconnect the system to the electrical outlet and turn the system on again.
- Enter the System Setup program.
If the date and time are not correct in the System Setup program, replace the battery (see "System Battery").
If the problem is not resolved by replacing the battery, see "Getting Help" for instructions on obtaining technical assistance.
|
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 (weeks or months), the
NVRAM may lose its system configuration information. This situation is not caused by
a defective battery.

- Turn off the system, including any attached peripherals, and disconnect the
system from its electrical outlet.
- Check the SCSI cable connection from the tape drive to the external SCSI
connector on the back panel.
- Check the SCSI cable connection from the external SCSI connector on the
back panel to the I/O riser card.
- Check the AC power cable connection to the tape drive.
- Verify that the tape drive is configured for a unique SCSI ID number and that the tape
drive is terminated or not terminated as appropriate.
See the documentation for the tape drive for instructions on selecting the SCSI ID and enabling or disabling termination.
- Reconnect the system to the electrical outlet and turn on the system.
- If the problem is not resolved, see "Getting Help" for instructions on obtaining
technical assistance.
- Faulty hard drive
- Faulty SCSI backplane board
- Faulty or loose SCSI cable connections to a RAID controller card

NOTICE: This troubleshooting procedure can destroy data stored on the hard drive. Before you
proceed, back up all the files on the hard drive.
|
- Reboot your system and enter the SCSI configuration utility by pressing
<Ctrl><h>, <Ctrl><a>, or <Ctrl><m>, depending on the controller.
- Check that the primary SCSI channel is enabled, and reboot the system.
See the documentation supplied with the controller for information on the configuration utility.
- Verify that the device drivers are installed and configured correctly.
See the operating system's documentation.
|
NOTE: If a drive shows signs of imminent failure, the status indicator blinks green, then
amber, and off, repeating this sequence every two seconds. If a drive has failed, the status
indicator blinks amber four times per second.
|
- Remove the faulty hard drive and install it in the another drive bay.
- If the problem is resolved, reinstall the hard drive in the original bay.
If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Replace the hard drive (see "Installing a SCSI Hard Drive").
If the hard drive still does not function properly in the original bay, the SCSI backplane board has a defective connector. See "Getting Help" for instructions on obtaining technical assistance.
- Check the SCSI cable connections inside the system:
- Turn off the system, including any attached peripherals, and disconnect the
system from its electrical outlet.
- Remove the front cover (see "Removing the Front Cover").
- Check the SCSI cable connection to the RAID controller card.
|
NOTE: To operate the SCSI backplane in a 1 x 8 configuration, make sure that the SCSI
cable is connected to the Channel A connector on the SCSI backplane's daughter card. To
operate the SCSI backplane in a 2 x 4 configuration, make sure that both SCSI cables are
connected to the daughter card.
|
- Partition and logically format the hard drive. If possible, restore the files to the drive.
To partition and logically format the drive, see the operating system documentation.
If the problem is not resolved, see "Getting Help."
Your system may contain an optional RAID controller card. If you encounter problems with the controller, see the RAID controller's documentation for detailed information on troubleshooting.
