standby power mode, the system power LED changes to amber.
5. If the server is installed in a rack, locate the server by identifying the illuminated rear UID LED button.

Access panel
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
CAUTION: Do not operate the server for long periods with the access panel open or removed.
Operating the server in this manner results in improper airflow and improper cooling that can
lead to thermal damage.
To remove the component:
1. Power down the server if the standard cable management solution is installed ("Power down the
server" on page 26).
NOTE: If the optional cable management arm is installed, you can extend the server and
perform hot-plug installation or maintenance procedures without powering down the server.
2. Extend or remove the server from the rack ("Extend the server from the rack" on page 26, "Remove
the server from the rack" on page 27).
3. Lift up on the hood latch handle and remove the access panel.
To replace the component, reverse the removal procedure.
