3 Remove the two screws from the footstand assembly and unsnap the
footstand assembly by pressing inward at the back of the footstand
where it meets the base and pulling upward.
4 If the telephone is equipped with a Meridian Programmable Data
Adapter (MPDA) or Meridian Communications Adapter (MCA), unplug
the data cable from telephone's base jack.
5 Remove the four screws securing the base of the telephone to the top
cover. Remove the base and set it aside.
6 If the telephone is equipped with a display, disconnect the display
ribbon cable from the display board and move it out of the way.
7 If the telephone is not equipped with the power supply board, remove
the jumpers from P1 connector pins on the main board. Go to step 9.
If the telephone is equipped with a power supply board, go to step 8.
8 The power supply board is located on the left side of the telephone.
Remove two small screws from the power supply board (near the top)
and set them aside. Grasp the board firmly on each side. Work the
board loose from the connector by slowly applying upward pressure to
alternate sides until released.
If the power supply board is not being replaced, place the jumpers
(A0288529) connecting the bottom two sets of pins on the P1
connector.
9 Place the power supply board so that the alignment pin on the
telephone fits into Slot A on the board. See Figure 31 on page 95 and
Figure 32 on page 96. Align the mounting holes in the board (near the
top) over the mounting holes in the telephone and carefully press down
so that the H1 connector on the board slides onto the P1 pins.
10 Take the self-tapping Phillips-head screws supplied with the power
supply board and install them into the mounting holes. Tighten firmly
with a #1 Phillips screwdriver.
11 If the telephone has a display, reconnect the display ribbon cable,
routing the cable as described in Procedure 1 on page 105.
Note: Do not allow R5 on the power supply board to become bent
during this procedure.
