Fujitsu SPARC Enterprise M5000 Overview Guide

Chapter 1 System Overview 1-15
1.3.4 Fan Unit
Both midrange servers use 172-mm fan units as the primary cooling system. The
SPARC Enterprise M4000 server also use two 60-mm fans.
FIGURE 1-11 and
FIGURE 1-12 illustrate the number of fans per midrange server, fan location, and the
fan types used in both midrange servers.
The fan units in both midrange servers move air currents into and out of the server.
The fans in both midrange servers are redundant. Because of the redundancy, system
operation continues when a failure occurs with one fan. If the midrange server has
two fans of each fan type, one fan of each fan type is redundant. If the midrange
server has a total of four fans, two of the four fans are redundant (
FIGURE 1-11 and
FIGURE 1-12). Fan failures can be detected by the eXtended System Control Facility
(XSCF).
The fans are accessed from the top of the midrange server.
FIGURE 1-11 and FIGURE 1-12 show the fan unit locations in both midrange servers.
