Replacing faulty components
This section covers replacing the flash card and hard
disk. Refer to the Hardware User Guide for instructions
on how to replace other components.
Replacing the flash card
Do not proceed with this procedure until you have
obtained the MOSS password for the system. This
procedure takes the system out of service for
approximately 60 minutes.
Note that the flash card does not include the voice mail
prompts.
To perform a flash card replacement you require
• Laptop or PC with Hyperterminal or equivalent
communication package
• System software CD-ROM (for the voice mail
software)
• Adapter cable.
You can build an adapter cable using a DB9 to RJ45
connector and a straight RJ45 patch cable. See
Cable pinouts (p. 231).
To perform a flash upgrade
1. Perform backups (including a voice mail data
backup).
2. On the laptop or PC, start up the Hyperterminal
application (click Start, click Programs, click
Accessories, click Hyperterminal and then click
Hyperterminal again).
3. Enter a name for the New Connection and click OK.
