Connecting Cisco Voice Network Modules to the Network
Step 3 Beginning with bank 0, insert the PVDM into the connector slot at an angle, tilted toward the right side
of the chassis. Align the PVDM in a vertical position (see
Figure 10 ) by using the minimum amount of
force required. When the PVDM is properly seated, the socket guide posts fit through the alignment
holes, and the connector springs click into place.
Step 4 Ensure that each PVDM is straight and that the alignment holes (as shown in Figure 9 ) line up with the
plastic guides on the socket.

Caution It is normal to feel some resistance, but do not use excessive force on the PVDM and do not touch the
surface components.
Step 5 Repeat Step 2 through Step 4 for each PVDM.
Voice Network Module LEDs
All network modules have an enable (EN) LED. This LED indicates that the module has passed its
self-tests and is available to the router. The following network modules have no additional LEDs. (See
Figure 11 for a sample faceplate.)
• NM-1V
• NM-2V
• NM-HD-1V
• NM-HD-2V
• NM-HD-2VE
