Before you begin
Observe the following precaution when replacing the riser assembly.
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection. Refer to the documentation that shipped
with your system for additional information.
Your controller enclosure model may vary slightly from what is illustrated
in this document.
Verifying component failure
Use the following method to verify component failure:
Check to see if there is power to the management module or power UID.
If the amber LEDs on the management module or power UID indicate a
failure, the riser assembly may have failed.
NOTE:
An indicated failure of the management module can also be
an indication of failure of the power supply or midplane board.
