Removing PVDMs
To remove PVDMs, follow these steps:
Step 1 Find the PVDM sockets on the HDV network module. (See Figure 7 .)
Caution Handle PVDMs by the card edges only. PVDMs are ESD-sensitive components and can be damaged by
mishandling.
Step 2 Remove one PVDM at a time, beginning with the PVDM in bank 4. To lift the PVDM out of its socket,
pull the locking spring clips on both sides outward and tilt the PVDM toward the right side of the chassis,
free of the clips. (See
Figure 9 .)

Step 3 Hold the PVDM by the edges with your thumb and index finger and lift it out of the socket. Place the
removed PVDM in an antistatic bag to protect it from ESD damage.
Step 4 Repeat Step 2 and Step 3 for each PVDM.
Installing PVDMs
To install PVDMs, follow these steps:
Step 1 Find the PVDM sockets on the HDV network module. (See Figure 7 .)
Caution Handle PVDMs by the card edges only. PVDMs are ESD-sensitive components and can be damaged by
mishandling.
Step 2 Hold the PVDM with the polarization notch on the right, near the front of the chassis, and the component
side away from you, with the connector edge at the bottom. (See
Figure 8 .)
2. Push the top of the
PVDM forward and down.
1. Pull the locking spring clips outward.
