To Perform a Hot Swap of a Power Module

.........................................................................................................................................................................................
When to use
Use this hot swap procedure to remove and replace a defective power module. Refer to
Figure 9, "Hot Swap Power Module" (p. 31)
Alarm indicators
The yellow Fault LED on the front panel of the Brick is lit when one of the power
modules fails or both fan units fail. Observe the Fan1 and Fan2 LEDs to determine if it is
a fan unit alarm, or the PS1 and PS2 LEDs to determine if it is a power supply alarm.
If it is a power supply alarm, check the green LED on the back of each power module at
the rear of the Brick to determine which is the defective module. The green LED will not
be lit on the defective power module.
Important! Make sure that the correct power module is identified for removal.
Otherwise, removal of the wrong power module may cause a shutdown of the whole
system.
