Installing and Removing PVDMs
PVDM Location and Orientation
The PVDM connectors are located on the system board, and are identified as follows:
•
In Cisco 2801 and Cisco 2811 routers—PVDM 0 and PVDM 1
•
In Cisco 2821 and Cisco 2851 routers—PVDM 0, PVDM 1, and PVDM 2
Refer to
Figure 8
,
Figure 9
,
Figure 10
, and
Figure 11
for PVDM locations.
PVDMs have a polarization notch on the mating edge to prevent incorrect insertion.
Figure 32
shows the
polarization notch on a PVDM.

Removing a PVDM
To remove a PVDM from the system board, follow these steps:
Step 1
Locate the PVDM on the system board. See
Figure 8
,
Figure 9
,
Figure 10
, or
Figure 11
, depending on
your router model, for the location of the PVDMs.
Step 2
Pull the PVDM retaining clips away from the PVDM at both ends, and then tilt the PVDM until it can
be freely removed from the connector. See
Figure 33
.
Note
PVDMs must be removed in order—PVDM 1 then PVDM 0 in Cisco 2801 and 2811 routers, and
PVDM 2, then PVDM 1, then PVDM 0 in Cisco 2821 and 2851 routers.
