Installing a hot-swap fan
The server comes with three replaceable double fans. For proper cooling, the
server requires that all three fans be installed at all times.
Attention: To ensure proper server operation, if a fan fails, replace it within 30
seconds. Have a replacement fan ready to install as soon as you remove the failed
fan.
To install any of the three replaceable fans, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 36.
2. If you have not done so already, slide the server out of the rack and remove the
cover (see “Removing the cover” on page 43).
Attention: To ensure proper system cooling, do not remove the top cover for
more than 30 minutes during this procedure.
3. Orient the new fan over its position in the fan bracket so that the connector on
the bottom aligns with the fan connector on the system board.
4. Align the vertical tabs on the fan with the slots on the fan cage bracket.
5. Push the new fan into the fan connector on the system board. Press down on
the top surface of the fan to seat the fan fully. Make sure that the amber LED
next to the fan connector on the system board is off.
