A WX4400 switch is shipped with a single 100-240 VAC autosensing AC
power supply. One power supply provides enough power for a fully
configured system. You can add a second power supply for load sharing
and redundancy. A WX4400 switch containing one power supply can
have the supply installed in either slot. If the switch contains two power
supplies and one supply fails, the other supply automatically takes over to
provide uninterrupted operation.
The power supplies are hot-swappable. You can remove or insert a power
supply while the other power supply is running.
Use the following procedures to install a second power supply or replace
a failed power supply.
To attach the power supply to an WXR100, see "Powering On a WX
Switch" on page 37.
1 If you are replacing a failed power supply and have not already removed
it from the WX switch, go to "Replacing a Power Supply" on page 35.
2 If you are installing a new power supply in an unused slot, loosen the
thumbscrew with a #2 Phillips-head screwdriver and remove the cover plate.
Store the cover plate in a safe place in case you need to use it at another
time.
3 Remove the new power supply from its packaging and lift the supply by
grasping the front handle with one hand and supporting the supply from
the bottom with the other hand.
4 Insert the power supply into the WX switch's slot as shown in Figure 9,
pushing gently but firmly until the supply is fully seated and flush with the
switch's front panel.
