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.

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

CAUTION: TO REMOVE A CARD, FIRST TURN OFF THE POWER AT THE POWER

SUPPLY UNIT(S). HANDLE THE CARD BY THE PLASTIC FACEPLATE OR LEVERS ONLY.

STATIC DISCHARGE CAN DAMAGE THE CARDS. ONCE REMOVED, CARDS SHOULD

Remove the panel on the front of the controller or expansion unit, following the directions

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

bottom lever of the card. The card will be disengaged from the controller when the levers are
