IP Communications High-Density Digital Voice or Fax Network Module Chapter 8 Connecting Voice Network 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 8-21.) If the PVDM LEDs are not green after initial installation and configuration, check that the PVDM2 modules are properly seated in their slots.
