Installing a Packet Voice Data Module
You can install a packet voice data module (PVDM) to support enhanced versions
of digital signal processors (DSPs).
Follow these steps to install a PVDM on the router motherboard:
Warning
During this procedure, wear grounding wrist straps to avoid ESD
damage to the router. Do not directly touch the backplane with
your hand or any metal tool, or you could shock yourself.
Step 1 Locate the PVDM slot on the motherboard, shown in Figure 2.
Step 2 Remove any existing PVDM by pulling the PVDM snaps (shown in Figure 7)
away from the PVDM.
Step 3 Hold the replacement PVDM with the double notched edge on your left.
Step 4 Insert the PVDM into the PVDM slot, making sure that the notches on the edge
of the PVDM are inserted over the bars inside the PVDM slot, as in Figure 7.
Step 5 Push the module towards the slot and press firmly until you hear a clicking sound
and the module is firmly seated in the slot, as shown in Figure 7.
