Trouble symptom

Action

•

If the system boots correctly, consider replacing the PCI
backplane because it is only partially functional.

•

If the system does not boot correctly, replace the PCI backplane.

Note: Each set of four slots is controlled by a different PCI bridge.
When you move the RAID card to the next set of four PCI slots, you
try to determine if the PCI bridge that controls the set of four PCI slots
in which the card was initially installed is defective.

The system boots, but the
keyboard or the mouse or
both are not functional.

The Y cable is connected incorrectly or is not the cable that Nortel
shipped with the system. The Y cable can also be plugged in
improperly.

The system does not boot
to CallPilot.

This symptom can indicate a multimedia card failure or a software
failure.

Check for multimedia card errors on the diagnostic screen that
appears immediately after the system is rebooted. If the multimedia
card functions properly, then investigate the software area; check
the Event Viewer for information on software failures.

The RAID controller
card displays SCSI IDs
from 0 to 6 for the hard
drives, although they are
configured on different
channels.

The jumpers of the SCSI drive backplane are installed. Remove
the jumpers. The displayed SCSI IDs must be from 0 to 2 on both
channels.

The RAID controller
displays the drives on the
second section as being on
channel 1 (the established
channels are 1 and 2).

The SCSI cables that connect the RAID controller card and the
SCSI drive backplane are inverted. Power down the system and
reconnect the cables so that they match the channels as indicated in
the 1002rp Server Maintenance and Diagnostics guide. The RAID
controller performs channel roaming without losing data.
