Procedure 1
Installing and removing the M2616/M2216ACD Power Supply Board on
NTZK sets
CAUTION WITH ESDS DEVICES
Before handling internal telephone components,
discharge static electricity from hands and tools by
touching any grounded metal surface or conductor
1 Remove the handset and place the telephone upside down on top of a
level, solid work surface (such as a desktop) covered with soft material
or paper to prevent damage to movable keys and the telephone face.
2 Disconnect all cords from the telephone.
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 an MPDA or MCA, unplug the data
cable from the base telephone jack.
5 Remove the four or five screws securing the base to the top cover.
Remove the base and set it aside.
6 If the telephone is equipped with 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 a power supply board, remove
jumpers from the 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 slowly until it is released.
If not replacing the power supply board, place the jumpers (A0288529)
connecting the bottom two sets of the pins on the P1 connector.
9 Place the power supply board so that Slot B fits into the alignment pin
on the telephone. See Figure 30 on page 91. Align the mounting holes
in the board (near the top) over mounting holes in the telephone and
carefully press down so that the H1 connector on the board slides onto
the pins of the header (P1 on the M2616 or J2 on the M2006/M2008).
