3.6 Installing Optional Modules
You can install two optional modules separately to meet the needs of your network. The procedure for installing the
optional modules is the same. Follow these steps to install the optional modules.
Step 1. Turn off your switch and unplug the power cord from the switch.
Step 2. Loosen the thumbscrews from the cover plate and remove the cover plate from the optional slot. Do not
discard the cover plate. You can put the cover plate back on if you remove the new module.

circuit components by holding it by the edge.

optional module snaps into place and secure it to the switch with the retaining screws.
