Telephones and Consoles Description, Installation, and Operation
When installing an MCA or MPDA to NTZK or NT2K phone sets with a date
code prior to January 1998, a Power Option board is required, along with an
additional power source. When installing an MCA in an NT9K phone set or
an NT2K with date code of January 1998, install only the MCA (an additional
Power Option board and Jumper board are not required).
The Power Supply Board connects to the telephone through a 14 pin bottom
entry connector.
The Power Supply Board comes factory installed with any configuration of
the M2216ACD-2. The M2006 and M2008 require the Power Supply Board
with the addition of any option. The M2616 requires the Power Supply Board
with any option except the Display Module.
Refer to Figure 55 on page 347 and Figure 56 on page 348 for power supply
board requirements.
