Removal and replacement procedures 57
3. Remove the hot-plug power supply from the server.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless
all bays are populated with either a component or a blank.
To replace the component, reverse the removal procedure.
Replacing hot-plug fans
The server supports redundant hot-plug fans ("Fan locations" on page 92) to provide proper airflow to the
server if a primary fan fails.
WARNING: To prevent personal injury from hazardous energy:
• Remove watches, rings, or other metal objects.
• Use tools with insulated handles.
• Do not place tools or metal parts on top of batteries.
IMPORTANT: Remove and replace one fan at a time. If the system detects two fan failures in
the same zone, the server shuts down to avoid thermal damage.
1. Extend the server from the rack, if applicable ("Extending the server from the rack" on page 27).
2. Remove the access panel ("Removing the access panel" on page 29).
3. Remove the malfunctioning hot-plug fan from the server.
