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.
Clearing the system configuration
RBSU can be used to restore the factory default configuration. For more information, see "HP ROM-Based
Setup Utility (on page 48 )." If the system is unable to boot into RBSU, use the following steps to clear the
system configuration:
1. Power down the server blade (on page 14 ).
2. Remove the server blade (on page 15 ).
3. Remove the access panel (on page 15 ).
4. Change position 6 of the system maintenance switch to on.
5. Install the access panel (on page 16 ).
6. Install the server blade in the enclosure and power up the server blade.
7. Wait for the POST message that prompts you to change the switch setting:
Maintenance switch detected in the "On" position.
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 through 7.
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 14 ).
2. Remove the server blade (on page 15 ).
3. Remove the access panel (on page 15 ).
4. Change positions 1, 5, and 6 of the system maintenance switch to on.
5. Install the access panel (on page 16 ).
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.
