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.)
