Environmental Monitoring and Reporting Functions
In systems with a single power supply, and in systems with redundant power when both power
supplies are shutting down, the OUTPUT FAIL LED lights momentarily as the system powers down,
but goes out when the power supply has completely shut down.

but goes out when the power supply has completely shut down.
Safety Interlock Mechanism
The power supplies feature the following three safety interlock features:
•
An on/off switch with a locking mechanism (see Figure 4) that prevents the power supply from
being removed from the chassis when the power supply switch is in the on (|) position. When the
switch is on, a metal tab extends into a slot in the chassis. When the switch is in the off (O)
position, the tab is raised and clears the slot.

position, the tab is raised and clears the slot.

A captive installation screw at the bottom of the power supply front panel provides electrical
grounding and prevents the power supply from vibrating or sliding out of the bay and dislodging
from the power connectors in the backplane. (See Figure 3.)

cable from being pulled out accidentally.

The power supplies are self-monitoring. Each supply monitors its own temperature and internal
voltages. An internal fan in each power supply draws cooling air from the rear of the chassis, through
the power supply, and out the front of the chassis. The power supply airflow is separate from that of
the rest of the chassis.

Environmental Monitoring and Reporting Functions
The environmental monitoring and reporting functions, controlled by the chassis interface board,
allow you to maintain normal system operation by identifying and resolving adverse conditions
before loss of operation.
allow you to maintain normal system operation by identifying and resolving adverse conditions
before loss of operation.
The environmental monitoring functions constantly monitor the internal chassis air temperature and
DC supply voltages and currents. Each power supply monitors its own voltage and temperature and
shuts itself down if it detects a critical condition within the power supply. If conditions reach
shutdown thresholds, the system shuts down to avoid equipment damage from excessive heat.
