M2317 Data Option
If an existing digital telephone was not originally equipped with the Data
Option, or if the existing Data Option has become defective, that option can
be added or replaced. The following procedure explains how to install the
Data Option for the M2317 telephone.
1 Remove the handset, and place the telephone upside down on a level
workplace (a desktop, for example).
2 Disconnect all cords from the telephone.
3 Loosen and remove five screws in the base of the telephone, lifting the
base upward.
4 If the telephone is not equipped with the ADO, proceed with step 5.
If the telephone is equipped with a defective ADO, carefully disconnect
the ribbon cable connector from the header connector in the digital
printed circuit board. Loosen and remove the two self-tapping screws
that fasten the ADO to the telephone base and remove the defective
ADO. Proceed with step 6. See Figure 26 on page 77.
5 Remove the breakout section in the rear of the telephone base by
tapping it with the handle of a small screwdriver.
6 Place the black plastic connector shroud over the RS-232-C interface
connector.
Note: It is not possible to install the shroud after the board has been
inserted in the telephone base.
7 Tip the circuit board up and insert it, connector end first, under the tabs
in the base. Position it over the molded locating pins; then lower the
board completely into position in the telephone base. Use the three
slotted, self-tapping screws supplied with the board and install them
through the mounting holes. Tighten the screws.
CAUTION WITH ESDS DEVICES
CMOS devices inside the telephone can be damaged
by electrostatic discharge. Before opening any
M2317 telephone, discharge your hands and tools by
touching any grounded metal surface or conductor.
