Action
If you have another CD-ROM disk, insert that CD-ROM disk into a known
operational IODU/C 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 this test is
successful, the message "Checking directory /cdx/xxxx_DMR.Nxx ended
successfully" is displayed.x
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 should be replaced.
Positively identify the NT SDID (8 digits engraved on the face of the
Security Device beneath the Nortel logo) with the NT SDID contained on
the keycode floppy disk label, and verify the NT SDIDs match.
Verify that the correct Install Program diskette is being used for the CP
card in your system.
