Upgrading the System
Replacing Modules
10-15
Follow these steps to replace a module in a 5-slot carrier:
1. Move the On/Off switch to the “Off” position (“O”).
2. Remove the power cord from the wall outlet.
3. If you have Release 4.0 or later:
a. Loosen the thumb screw at the bottom of the carrier cover.
b. Rotate the carrier cover to disengage the tabs at the top of the modules from the openings
on the top of the carrier.
If you have Release 3.0 or earlier:
a. Loosen the screw on the lower front of the cover.
b. Place one hand on the handle on the bottom front of the cover and place your other hand
on the top of the cover, and gently pull the cover up and away from the carrier. Be careful
not to break the tabs that attach the cover to the carrier.
4. Before installing a module, remove the clear, plastic protector from the connector area on the
rear of the module by grasping the tabs on the ends of the protector and lifting (see
Figure 10-11 ).
Figure 10-11. Removing the Plastic Protector
5. Check the slack in the wires. If there is not enough slack to remove the module without pulling
the line and extension cords free, label and disconnect the wires.
6. Place one hand on top of the module. With the other hand, grip the plastic bracket on the
bottom front of the module, and pull out the old module (see
Figure 10-12 ).
