Feature Overview
Power Connections for Redundant Power Supply
The power connections for the redundant power supply are located on the back of the unit.
The redundant power supply contains two power supply modules. Each power supply module is
capable of powering the entire recorder, if necessary. If one module fails, the other module powers
the recorder alone until the failed module is replaced. The switch between the power supply
modules is seamless, so that normal use of the recorder is not affected.
You must connect the unit to two power outlets using two connected AC power cords. If one of the
power supply modules is not connected, an alarm sounds and an alert is generated.
•
An alarm sounds and a software alert is generated if one of the power supply modules fails or is
not connected.
•
You can silence the alarm by reconnecting the cable or replacing the failed module.
See “Replacing a Redundant Power Supply Module” on page 29.
•
The LED on the back of the failed 2U power supply module is solid amber, the LED on the back
of the failed 1U power supply module is unlit. (The LED on a correctly functioning power supply
module is solid green.)
Important:
Ensure that you only use the AC power cords supplied with your recorder unit. Failure to
use the correct power cords can result in damage to the power supply or unexpected power loss.
