Replacing a Hot-plug System Fan Unit
The PRIMERGY RX800 S2 server comes with four 80-mm hot-plug fans in front
of the PCI-X slots and four 92-mm hot-plug fans in front of the memory cards
(overview: see figure 24 on page 109). The following removal and installation
procedures apply to either size fan.
V
CAUTION!
Defective fans should be replaced as soon as possible. Never leave a fan
bay empty for longer than two minutes during operation. Otherwise,
system components might be damaged because of excessive tempera-
tures.
I
When a fan fails or is removed, the other fans in the server speed up to
maintain a safe operating temperature in the server until the fan is
reinstalled or replaced. When the new fan is installed correctly, the fans
will slow down.
