Removal and replacement procedures 61
• 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.
2. Remove the access panel ("Removing the access panel" on page 19
).
3. Remove the malfunctioning hot-plug fan from the server.
4. Install the replacement fan.
5. Repeat to replace additional fans as needed.
6. Observe the LED on each installed fan to be sure it is illuminated green
("Hot-plug fan LEDs" on page 116
).
7. Observe the internal system health LED on the front panel to be sure it is
illuminated green ("Front panel LEDs and buttons" on page 93
).
NOTE: If the front panel internal system health LED is not green
after you install hot-plug fans, reseat the hot-plug fan or refer to the
troubleshooting section.
