Replacing a Defective Controller Module
Note: In a switch with two installed Controller modules, removal of the active Controller module causes a
fast reset (the standby Controller module becomes the active Controller module). In a switch with
one installed Controller module, removal of the Controller module causes the switch to go down.
To remove a Controller Module:
1. Loosen the screws at the top and bottom of the module faceplate until the screws disconnect from the
switch.
2. Grasp the end of the module ejector at the lower left corner of the faceplate, and pull it down. This
action causes the ejector to exert pressure on the switch, forcing the Controller Module out of the slot
so its faceplate can then be grasped.
3. Grasp the faceplate and pull the Controller module straight out of the slot.
Note: If you have a standby Controller module installed, make sure the Standby LED (STBY) is ON
before attempting to remove the active Controller module.
To insert a replacement module, see page 33.
