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.
