Table 2 LED description
LED
Power input status
LED (AC OK or
Input)
Power output status
LED (DC OK or
Output)
If the power input LED is on but the output LED is off, an output issue
might have occurred. To resolve the issue:
1. Turn off the power switch on the power module and reconnect
the power cord.
This operation resolves the power module failure caused by an
output overvoltage, output short-circuit, or output overcurrent
condition. The power module shuts down and latches off if one
of these conditions occurs and cannot automatically restore
operation.
2. If the issue persists, the temperature might be high. Take
measures to decrease the temperature to an acceptable range.
The power module will automatically restore operation.
Status Description

Off
input failure has occurred.

No power is being output or an
Off
output failure has occurred.
On Normal power output.
