1.4 Power and Cooling Module
Figure 6 illustrates a power and cooling module (PCM). Each SS8460 enclosure houses two,
hot-swappable, fully redundant PCMs located in the rear of the chassis. Each PCM has
integrated fans for cooling the enclosure. A single PCM can provide sufficient power to the
enclosure; however, both modules are required for proper cooling of the enclosure.
There are four LEDs mounted on the PCM to indicate the status of the module and the fans
(Figure 7). Refer to Section 3.1.5 "Power and Cooling Module LEDs" for description of the
color and status of the LEDs.
1.5 5V Regulator
Each SS8460 enclosure houses two, hot-swappable, fully redundant 5V regulator modules in
the rear of the chassis. The module will regulate 5V from the 12VDC provided by the PCM.
There are three LEDs mounted on the 5V regulator to indicate the status of the module
(Figure 9). Refer to Section 3.1.6 "5V Regulator LEDs" for description of the color and status
of the LEDs.
