Suggested action
Verify that:
v The primary IDE channel is enabled in the Configuration/Setup Utility program.
v All cables and jumpers are installed correctly.
v The correct device driver is installed for the DVD-ROM drive.
Note: When two servers are connected in a 16-way configuration, the
DVD-ROM, diskette drive, keyboard port, USB ports (except for Remote
Supervisor Adapter II-EXA functionality), mouse, and video are disabled on the
secondary server.
If there is a diskette in the drive, verify that:
v The diskette drive is enabled in the Configuration/Setup Utility program.
v The diskette is good and not damaged. (Try another diskette if you have one.)
v The diskette contains the necessary files to start the server.
v Your software program is working properly.
Note: When two servers are connected in a 16-way configuration, the
DVD-ROM, diskette drive, keyboard port, USB ports (except for Remote
Supervisor Adapter II-EXA functionality), mouse, and video are disabled on the
secondary server.
If the diskette drive in-use light stays on or the server continues to bypass the
diskette drive, call for service.
Call for service.
Verify that:
v All cables and cords are connected securely to the rear of the server and
attached options.
v When the server is turned on, air is flowing from the rear of the server at the fan
grille. If there is no air flow, the fan is not working. This causes the server to
overheat and shut down.
v Ensure that the SCSI bus and devices are configured correctly and that the last
external device in each SCSI chain is terminated correctly.
If the problem remains, call for service.
v Make sure that the keyboard cable is properly connected to the server.
v Make sure that the server and the monitor are turned on.
v Try using another keyboard.
Note: When two servers are connected in a 16-way configuration, the
DVD-ROM, diskette drive, keyboard port, USB ports (except for Remote
Supervisor Adapter II-EXA functionality), mouse, and video are disabled on the
secondary server.
If the problem remains, call for service.
