4 Maintaining Power Supply Modules
The array includes two hot-swappable, combination power supply and cooling
modules.
Interpreting the LEDs
Use the power supply and cooling module LEDs, shown in Figure 4-1 and
described in Table 4-1, to determine the module status and identify problems. The
power supply and cooling module LEDs show the power, fan, and array status.
