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 58). • Access the redundant ROM ("Accessing the redundant ROM" on page 58). To complete these procedures, you must change physical settings on the system maintenance switch. Clearing the system configuration To clear the system configuration: 1. Power down the server blade (on page 24). 2. Remove the server blade (on page 24). 3. Remove the access panel ("Access panel" on page 25). 4. Change position 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. 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 not corrupted, use RBSU to switch to the redundant ROM. Component identification 58
