LED Status
Meaning
Analysis
Power module
status LED
Green
The power module is
operating correctly.
N/A
Red
The power module is
operating
abnormally.
This status occurs in the following cases:
•
The power module generates an alarm due to input
under-voltage, output short-circuit, output over-current,
output over-voltage, or over temperature, and enters
the protection state.
•
A fan failure occurs.
Off
A power input
problem occurs.
This status occurs in the following cases:
•
The power module is faulty.
•
A power cable connection problem occurs.
•
The external power supply is unavailable.
•
The power module is not switched on.
PSR650-A/PSR650-D power module status LED
The PSR650-A/PSR650-D power module provides a red-green status LED.
