Removing and Installing the Power Supply Module
The two (primary and redundant) power supply modules are identical. Each power supply
module has a 2‑color status LED, visible on the rear panel, 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.
NOTE: The power supply modules are hot‑swappable. Either power supply can be
removed of installed without powering down the switcher.
Removing the Power Supply Module
Remove a power supply module as follows:
1. Rotate the left and right knurled knobs to completely loosen the captive screws.
2. Gently pull on the handle to loosen the power supply from the backplane (see figure 66).
3. Slide the power supply out of the chassis.
