This chapter provides the following information:
• A functional description of the PSAX 4500 Alarm module
• Hardware features of the PSAX 4500 Alarm module
• Required components to install the PSAX 4500 Alarm module
• Instructions for installing the PSAX 4500 Alarm module
• Instructions for removing the PSAX 4500 Alarm module
The PSAX 4500 Alarm module provides two connectors that allow for con-
nections with external facility sensor inputs (doors, temperature, and so on),
chassis alarm outputs (visible and audible), external device controls (cooling,
heating, doors, and so on), and audible alarm cutoff controls (see Figure 2-1).
In addition, the CPUn module generates trap messages that reflect state
changes of the PSAX 4500 Alarm module's sensor inputs, control outputs,
and alarm cutoff control.
Figure 2-1. Example Configuration with the PSAX 4500 Alarm Module
The PSAX 4500 Alarm module is functionally identical to the Alarm module
(model 20N79), but the module is designed to be mounted only in the rear
panel (slot ) of the PSAX 4500 chassis. This enables you to make maximum
14
use of the front panel I/O slots. The module uses midplane bus traces that do
not impact midplane bus utilization calculations.
