6. When the card is free, slide it carefully out of the receiver.
7. Carefully slide the replacement card into its guides (both top and bottom) until it fits into its connector
at the back of the receiver. Gently push the card as far into the connector as you can. The card is now in
place.
8. Connect telephone line(s) or the line to the transceiver if installing a MX8000-LRR Radio Line Card.
(See Section 3.9 for telephone line installation.) In approximately 60-90 seconds the new line card will be
restored into the system with the line card LEDs working normally and a message similar to the
following will be printed on the MX8000 printer.

Caution:
To reduce the risk of electrical shock and damage to the receiver, follow these steps in the order
they are listed here.
1. While holding the front plate, unscrew the two front plate retaining screws located on the front of the
panel. (See Figure 3–1 for front plate retaining screw locations.)
2. Open the MX8000's front panel by pulling the left side of the front plate slightly forward and then to the
left to remove it from the receiver.
3. When the front panel is removed, you will see that there are 12 slots for line cards. The receiver
recognizes each slot by number 1 through 12 (slot one is closest to the keypad and display). It is not
necessary to put line cards in numbered order because the receiver continually polls each slot to see if
existing line cards are functioning and if it is still in its slot. The receiver also looks to see if a new line
card has been added. Figure 3–6 shows where each line card should be placed.
