Fan Module Overview
The fan modules are mounted across the width of the chassis between the hard drive
cage and the CPU modules. They are accessed by lifting the top cover door.
The minimum number of fan modules installed in the server is different for the two
server models:
■ SPARC Enterprise T5120 Servers contain at least four fan modules.
■ SPARC Enterprise T5220 Servers contain at least three fan modules.
Each fan module contains two fans mounted in an integrated, hot-swappable CRU. If
a fan module fails, replace it as soon as possible to maintain server availability.
Caution – Hazardous moving parts. Unless the power to the server is completely
shut down, the only service permitted in the fan compartment is the replacement of
the fan modules by trained personnel.
