Figure 7 PVDM Slot Locations

PVDM Orientation

PVDMs are manufactured with a polarization notch to ensure proper orientation and alignment holes to

ensure proper positioning. Figure 8 shows the polarization notch and alignment holes on a PVDM card.

PVDM cards are installed with the connector edge down, the polarization notch near the front of the

chassis, and the component side facing the right side of the chassis.

Caution To avoid damaging ESD-sensitive components, observe all ESD precautions. To avoid damaging the

HDV network module, avoid using excessive force when you remove or replace PVDMs.
