Removing and Installing a Power Supply Module
Each power supply module has a 2-color LED that indicates the status of the power supply
outputs. If the LED is lit green, the power supply is operating normally. If the LED is lit red,
the supply has failed and should be replaced at the earliest opportunity.
Removing a Power Supply Module
NOTE: The power supply modules are hot-swappable. Any power supply can be
removed without powering down the switcher.
Remove a power supply module as follows:
1. Rotate the left and right knurled knobs to completely loosen the screws.
2. Gently pull on the handle to loosen the power supply from the backplane (see figure 78).
3. Slide the power supply out of the chassis.
