Connecting Cisco Voice Network Modules to the Network
Step 2
Hold the PVDM2 module with the polarization notch on the right, near the back of the chassis, with the 
connector edge at the bottom. (See 
Step 3
Again, to make your job easier, begin with socket 0, then socket 1, or socket 2, then socket 3. Insert the 
PVDM2 module into the connector slot at an angle, tilted toward the left side of the chassis. Align the 
PVDM2 module in a vertical position (see 
), by using the minimum amount of force required.
When the PVDM2 module is properly seated, the socket guide posts fit through the alignment holes, and 
the connector springs click into place. 
Step 4
Ensure that each PVDM2 module is straight and that the alignment holes (as shown in
) line
up with the plastic guides on the socket.
Note
Be sure to align the alignment notch in the bottom of the PVDM2 module with the rib in the 
80-pin socket.

Caution
It is normal to feel some resistance, but do not use excessive force on the PVDM2 module, and do not 
touch the surface components.
Step 5
Repeat

for each PVDM2 module.
NM-HDV2 Network Module LEDs
IP communications high-density digital voice or fax (NM-HDV2) network modules have an enable (EN) 
LED, and four LEDs for the PVDM2 modules, numbered 0 through 3. The enable LED indicates that the 
module has passed its self-tests and is available to the router. The PVDM 0 through PVDM 3 LEDs 
indicate the current operating condition of the PVDM2 modules installed on the card. (See 
If the PVDM LEDs are not green after initial installation and configuration, check that the PVDM2 
modules are properly seated in their slots.
