Caution
Power supplies that support PoE cannot be installed in switches that do not support PoE. The
switch operating system prevents PoE power contribution from a power supply that is not
listed for use with that particular switch model.
Replacing a 150 W AC Power Supply
The 150 W AC PSU (Model XN-ACPWR-150W with front-to-back ventilation airflow) is compatible with
5420F-24T-4XE, 5420F-24S-4XE, 5420F-48T-4XE, 5420M-24T-4YE, and 5420M-48T-4YE switch
models.
5420F models have 1 hot-swappable PSU and 1 fixed PSU. 5420M models have 2 hot-swappable PSUs.
In a switch with a redundant power configuration, you can replace one AC power supply without
powering down the switch.
