System maintenance switch procedures
When you perform troubleshooting steps, this guide may instruct you to perform the following procedures:
• Clear the system configuration (" Clearing the system configuration " on page 8 ).
• Access the redundant ROM (" Accessing the redundant ROM " on page 9 ).
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

system configuration:
1. Power down the server blade (on page 11 ).
2. Remove the server blade (on page 12 ).
3. Remove the access panel (on page 13 ).
4. Change position 6 of the system maintenance switch to on.
