Fan redundancy supportFan redundancy support
The number of fans installed in the server determines fan redundancy. When redundant fan mode is enabled, hot-plug fan operation is
supported.
In this server, fan operation can either be:
Hot-plug—A failed fan can be replaced without powering down the server.
Non-hot-plug—To replace a failed fan, the user must either:
Keep the server powered on and complete the fan replacement within 60 seconds of opening the access panel, or
Power down and disconnect all power from the server before removing the access panel for fan replacement.

About this taskAbout this task
Only the server in rack mode supports fan replacement in hot-plug mode.
CAUTION:CAUTION: To maintain proper system cooling, do not operate the server for long period with the access panel open or
removed. Operating the server in this manner results in an improper system airflow. For internal hot-plug component
procedures, complete the procedure within 60 seconds. Failure to do so can cause the system temperature to increase and
trip the safety threshold. When this happens:
The health LED flashes amber.
The operating system gracefully shuts down.
ProcedureProcedure
1. Extend the server from the rack .
2. Remove the access panel.
3. Remove the internal fan:
a. Press and hold the latch (callout 1).
b. Lift the fan from the bay (callout 2).
