If you have another CD-ROM disk, insert that CD-ROM
disk into a known operational Drive Carrier card, and
load the Software Installation Tool from the correct
Install Program diskette.
In the Software Installation Tool, go to the Tools Menu
and select option:
<j> -To check the customer-specific part
of the CD-ROM
If the test is successful, it is unlikely the CD-ROM disk is
damaged.
However, if the test indicates a failure to read all files on
the CD-ROM disk, then the CD-ROM disk is damaged
and must be replaced.
Remove the CD-ROM disk from the CD-ROM drive,
place it in the CD-ROM drive of the other Call Server,
and test operation.
If the CD-ROM disk is operational, replace the Drive
Carrier card containing the faulty CD-ROM drive.
Adjust room temperature as necessary. Allow the
system to cool for a few minutes, then reset the system.
Verify that the fans in the alarm fan/module are
operational.
Unseat and re-install alarm/fan module. If the fault
continues, replace the alarm/fan module.
Check filter to ensure it is clean. If the filter is dirty or
damaged, clean or replace the filter as described in
"Cleaning and replacing the power supply air filter" on
page 123.
