Chapter 3 Maintaining the Sun Fire Servers 3-39
Caution – The fans are hot-swappable and can be removed and replaced while the
system is running. Do not hold the fan bay door open for more than 60 seconds at a
time to avoid overheating the server. Remove and replace only one fan at a time.
The internal system software designation of the fan connector boards, or fan trays
(FT), and fan modules (FM) is shown in
FIGURE 3-30 (viewed from the front of the
server).

1. 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.
2. Open the door to the fan bay and identify the defective fan module.
■ Fan module LED lit: The fan module is faulty and should be replaced.
■ Fan module LED off: The fan module is operating properly.
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. While holding the fan bay door open, grasp the faulty fan module by its plastic
strap and lift it straight up out of the fan bay. See
FIGURE 3-31.
