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
The 600 W, 920 W, 1200 W, and 2000 W AC power supplies that support PoE cannot be
installed and used in a switch that does not support PoE.
Note
The switch operating system prevents PoE power contribution from a power supply that is
not listed for use with that particular switch model.
You need the following tools and materials to replace a 600 W, 920 W, 1200 W, or 2000 W AC PoE
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 600 W, 920 W, 1200 W, or 2000 W AC PoE 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.
