Install an Additional Power Supply Unit
In models with more than one power supply bay, you can install an 
additional PSU.

To install an additional PSU:
1.  Pull out the cover plate from the power module bay in which you want 
to insert the additional PSU.
2.  Insert the additional PSU into the power module bay, and gently push 
the PSU into the bay.
CAUTION: 
When inserting the PSU, do not use unnecessary force. 
Doing so can damage the connectors on the back of the PSU and on the 
midplane.

3.  Connect the end of the power cord to the power receptacle on the PSU.
4.  Plug the AC power cord into a power source such as a wall socket or power 
strip.
When you apply power, both the AC OK LED on the PSU and the switch’s 
Power LED that is associated with the power supply bay light. If these LEDs 
do not light, make sure that the power cord is plugged in correctly and that 
the power source is good.
Replace a Power Supply Unit
In models with more than one PSU, the PSUs are hot-pluggable.

To replace a PSU:
1.  If your switch functions with a single PSU only, disconnect the power cord 
from the PSU and let the switch power down.
If your switch functions with more than one PSU, you do not need to power 
down the switch and you can perform a hot swap. 
2.  Remove the PSU from the power module bay by moving the orange release 
latch to the left and pulling the extraction handle.
AC OK LED. All PSUs provide one AC 
OK LED. During normal operation, this 
LED must light green to indicate that 
valid AC is power is applied to the PSU.
DC OK LED. Model APS150W also 
provides one DC OK LED. During 
normal operation, this LED must light 
green to indicate that the DC outputs 
are within regulation limits.
