Turn off the power switch on the power supply unit. The power indicator light will go off.
If you have an expansion unit as part of your system, be sure to turn off the power switch on
its power supply unit as well. Customization information will be retained.
■ Remove the front panel.
Remove the front panel from the controller or expansion unit by first loosening the screw
located at the bottom center of the unit. Lift the panel up and away from the unit; the screw
will still be in the panel. Remove and discard the packing material inside the panel.

■ Remove the line or station card from its box and protective packaging.
CAUTION: HANDLE THE CARD BY THE PLASTIC FACEPLATE ONLY. STATIC

■ Insert the card into the appropriate slot (LINE or STATION) in the controller.
Holding the plastic faceplate, align the back edge of the card with the grooves on the
controller. Push the card firmly in until the mating connectors are fully engaged. The card is
installed when the plastic faceplate is flush with the surrounding controller plastic and cannot
be pushed any further.
CAUTION: DO NOT TURN ON THE POWER UNTIL YOU ARE SURE ALL CARDS ARE
FIRMLY SEATED.
■ Connect the new line cords and or telephone cords to the appropriate modular jacks.
(See SPIRIT Communications System Model 2448,1224 Controller, Customer Installation
Instructions.) The line and station jacks on the controller are numbered on the plastic frame to
the left of the card slots. Be sure to label each end of each cord. Record the appropriate
numbers on the System Directory Label on the back of the panel.
■ Replace the front panel.
Locate and engage the bottom two hooks on the panel into the housing. Lift up until the top two
hooks on the panel engage and then pull down. Tighten the screw at the bottom of the panel.
■ Turn the system on.
Turn on the power switch(es) on the power supply unit(s). The power indicator light(s) will light.
Removing a Line or Station Card

on the preceding page. Simultaneously pushup on the top lever of the card and down on the
