Removing and Replacing a Power Supply Module

© Copyright Lenovo 2019
The rear panel of the G8272 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.
