System maintenance switch procedures
When you perform troubleshooting steps, this guide may instruct you to perform the following procedures:
• Clear the system configuration.
• Access the redundant ROM.
To complete these procedures, you must change physical settings on the system maintenance switch.
Accessing the redundant ROM
If the system ROM is corrupted, the system automatically switches to the redundant ROM in most cases. If
the system does not automatically switch to the redundant ROM, perform the following steps:
1. Power down the server blade (on page 23).
2. Remove the server blade (on page 24).
3. Remove the access panel ("Access panel" on page 25).
4. Change positions 1, 5, and 6 of the system maintenance switch to on.
5. Install the access panel ("Access panel" on page 25).
6. Install the server blade in the enclosure and power up the server blade.
7. After the system beeps, repeat steps 1 through 3.
8. Change positions 1, 5, and 6 of system maintenance switch to off.
9. Repeat steps 5 and 6.
If both the current and backup versions of the ROM are corrupt, return the system board for a service
replacement.
To switch to the backup ROM when the System ROM is not corrupt, use RBSU.
