Power off the server and turn switch to the "Off" position.
8. Repeat steps 1 through 3.
9. Change position 6 of the system maintenance switch to off.
10. Repeat steps 5 and 6.
IMPORTANT: When the server blade boots after NVRAM is cleared, a delay of up to 2 minutes
is normal. During this delay, the system appears non-functional. Do not attempt any procedures
during the delay.
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.
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.
