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 Figure 18.)

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 Figure 20), 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 Figure 19) 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.

Figure 20 Installing PVDM2 Modules

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 Step 2 through Step 4 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 Figure 21.)

If the PVDM LEDs are not green after initial installation and configuration, check that the PVDM2

modules are properly seated in their slots.

1. Insert the PVDM2 into the socket

at an angle from vertical.

The socket guide posts fit through

the holes in the PVDM2.

The locking springs clip the back

of the PVDM2.
