CONNECTING THE EXPANSION MODULE
The expansion module (shown on the left in Figure 2) shall be connected to the 6416 or 6424-type telephone
(shown on the right in Figure 2) with the D6AP-87 cord.
NOTE:
To successfully power the XM24, a D8W modular cord must be connected to the 6416 or 6424-type
telephone and the power unit (see Power Requirements). The D2R telephone line cord will not supply power to
the XM24.
NOTE:
The 6400 Series telephone with an attached expansion module can be used only on a flat surface such
as a desk. The telephone and expansion module CANNOT be wall-mounted.

Snap one end of the cord into the 6-pin Expansion Module jack, labeled “XM24” (

Series telephone and then thread the cord upwards through the routing channel (

Figure 2.

Thread the other end of the D6AP-87 cord downwards through the routing channel (

module and snap the free end of the cord into the 6-pin jack, labeled “TEL SET” (

expansion module.
Figure 2 shows the connection of the 6416-type telephone to the expansion module. (The expansion module is
connected to the 6424-type telephone in exactly the same way.)
