10.1 Fan Module Replacement
The 172-mm fan module is the primary cooling system. The 172-mm fan module is in
both midrange servers. The 60-mm fan module is for additional cooling in the
SPARC Enterprise M4000 server. The fan modules are hot, active, or cold replacement
components. When using active replacement, only one fan module should be
replaced at a time to ensure redundancy. The fan backplanes are cold replacement
components.
