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.
