APPENDIX E: Installing Modules in the Matrix ServSwitch

E.2 Swapping In an Expansion Module

Making sure that the Matrix ServSwitch is turned OFF and unplugged, unscrew and remove any blank plate over the opening of the Matrix ServSwitch’s Expansion slot. (You should always have a plate covering this slot when a Terminator Module is in it. If there is a plate, you can save it if you want to, but you shouldn’t need it any more; the Expansion Module has its own termination circuitry, so you wouldn’t normally ever have to replace it with a Terminator Module, even if you go back to operating the Switch by itself.)

Now, using needlenose pliers or a similar tool, reach far back in the slot (at the level of the slot’s widest point) and gently remove any Terminator Module installed in it, as shown at the top of Figure E-2. (You should never leave the Switch without any module at all installed in this slot, because the Switch will be totally disabled.) Carefully push the Expansion Module into the now-vacant slot, as shown at the bottom of Figure E-2—being careful not to pinch the wiring near the internal block connector—and screw the Module on securely.

Once the Expansion Module is installed, you can run Expansion Cables from the Module’s IN and OUT ports to your other Switches; see Section 3.4.
