Hot Swap FAN
The system has five hot swappable fan modules (six
fans). The failed fan module can be easily removed or
replaced without turning power off. Each fan module
has a fan alarm LED and each fan is redundant in
configuration. If one fan fails, its associated fan
changes its rotating speed to high. Table 2-6 lists the
fan redundant pairs. Figure 2-10 shows the fan
features from the front of the chassis and Figure 2-11
shows the fan features from the rear of the chassis.
