3.12.7 Replacing a Fan Connector Board
Note – This component is a CRU and can be replaced by anyone.
Supported components and their part numbers are subject to change over time. For
the most up-to-date list of replaceable components for these servers, refer to:
http://sunsolve.sun.com/handbook_pub/Systems/
1. Click the name and model of your server.
2. On the product page that opens for the server, click Full Components List
to view a list of components.
Use the following procedure to replace a fan connector board.
1. Power off the server as described in
Section 3.4 on page 3-4.
2. If the server is in a rack, slide it far enough from the rack so that you can open
the fan bay door. If you cannot safely view and access the component, remove
the server from the rack.
Caution – When you open the fan bay door, be careful to hold it open with one
hand so that it does not spring shut and injure your fingers. Do not hold the fan bay
door open for more than 60 seconds while the server is running to avoid overheating
the server.
3. Open the fan bay door and hold it open. See
FIGURE 3-31 on page 40.
4. Remove the three fan modules that are connected to the fan connector board
you are replacing. Grasp each fan module by its plastic strap and lift it straight
up out of the fan bay.
5. Visibly inspect the remaining fans and all air openings for dirt, and clean if
necessary.
Note – System cooling might be affected by dust and contaminant build-up.
Therefore, you should open and check systems approximately every six months (or
more often in dirty operating environments). Check system heatsinks, fans, and air
openings. If necessary, clean systems by carefully brushing, blowing, or vacuuming
contaminants from the system.
