PVDM2 Module Orientation

PVDM2 modules are manufactured with a polarization notch to ensure proper orientation, and alignment

holes to ensure proper positioning. Figure 18 shows the polarization notch and alignment holes on a

PVDM2 module. PVDM2 modules are installed with the connector edge down, the polarization notch

near the back of the chassis.

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

NM-HDV2 network module, avoid using excessive force when you remove or replace PVDM2 modules.
