Telephones and Consoles Description, Installation, and Operation
Procedure 68
Installing and removing the Meridian
Communications Adapter or the Meridian
Programmable Data Adapter
If using a NT9K phone or the NT2K with date code of April 24, 1998 and later,
it is not necessary to install a Power Option board to operate the MCA.
1 Remove the handset and place the telephone upside down on top of a
level, solid work surface (a desktop, for example) 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 footstand.
• For NT2K and NTZK with date code prior to April 24, 1998 remove
the two screws from the footstand assembly and unsnap the
footstand by pressing inward at the back of the footstand where it
meets the base and pull upward. Discard the footstand. The
redesigned footstand ordered with the ATA is used instead.
• For NT9K and NT2K with a date code of April 24, 1998 and later,
retain the footstand and skip to Procedure 10 on page 390.
4 If the telephone is not equipped with the Meridian Programmable Data
Adapter (MPDA) or Meridian Communications Adapter (MCA), go to
Procedure 6 on page 389. If replacing an existing MPDA or MCA,
carefully disconnect the end of the 8-pin TELADAPT jack plugged into the
telephone by pressing firmly on the latch-tab and slowly lifting up.
5 Turn the telephone footstand assembly over and put it in the normal use
position. Remove the two self-tapping screws that fasten the MPDA or
MCA to the telephone footstand assembly and remove the MPDA or MCA
by pulling outward and up. Go to Procedure 11 on page 390 to replace the
MPDA or MCA.
6 Remove the back covering of the phone base by removing the four
screws.
