Removing and Replacing a Power Supply Module
50
NE2572O Installation Guide
The rear panel of the NE2572O has two bays for hot‐swap power supply modules.
Two active power supply modules are required for load‐sharing and redundancy. If
one power supply module fails, you can replace it without powering off the switch
or disrupting switch functions.
For proper airflow when operating the switch with only one power supply module,
the empty power supply bay must be closed by a blank power filler plate.
