Chapter 2 Description

PSM Module and Faceplates

On the chassis, faceplates on each PSM card provide EMI protection and visual indicators as to the card’s

status. The PSM faceplate has LED indicators to display alarm status (see Figure 2-5).

Unused slots have blank faceplates.

All external connectivity to the PSM module is through its midplane connector. Each PSM module has

its own temperature sensor for detecting over-temperature conditions, and generates an individual

over-temperature major alarm.

Multiple PSM modules per chassis can be configured to back up as many as four primary PSM modules

in the chassis (See “PSM Card Redundancy” section on page 1-6).
