Replacing a 150 W AC Power Supply

Replacing a 600 W, 920 W, 1200 W, or 2000 W AC PoE Power Supply
This topic describes how to replace internal AC power supplies in a switch.
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.
Caution
A 150 W AC power supply cannot be installed and used in a switch that
supports PoE.
You need the following tools and materials to replace a 150 W AC power supply:
•
Thermal protective gloves
•
AC power cord, if you will not be re-using the cord from the removed power supply
To replace a 150 W AC power supply, follow these steps:
1. Disconnect the AC power cord from the wall outlet and from the power supply.
2. Note the orientation of the installed power supply, and the location of the latching
tab at the right of the unit.
