LED Status Meaning Analysis
Red
A PoE power output
problem occurs.
This status occurs in the following cases:
• The PoE output voltage is not in the rated
voltage range.
• The PoE power switch is not turned on.
Off No PoE power is output.
This status occurs in the following cases:
• The power module is faulty.
• A PoE input power cable connection problem
occurs.
• The external power supply is unavailable.
PSR6000-ACV power module status LEDs
The PSR6000-ACV power module provides eight red-green status LEDs: system power input LED (SYS IN),
system power output LED (SYS OUT), fan LED (SYS FAN), power input LED (PoE IN1, PoE IN2, and PoE
IN3), power output LED (PoE OUTPUT), and PoE fan LED (PoE FAN).

LED Status Meaning Analysis
SYS IN
Green
The system power is
input correctly.
N/A
Red
A system power input
problem occurs. The system input voltage is not in the rated voltage
range.
Off
No system power is
input.
This status occurs in the following cases:
• The power module is faulty.
• A system input power cable connection problem
occurs.
• The external power supply is unavailable.
SYS OUT
Green
The system power is
output correctly.
N/A
Red
A system power output
problem occurs.
This status occurs in the following cases:
• The power module generates an alarm due to output
short-circuit, output over-current, output over-voltage,
or over temperature, and enters the protection state.
• The system power switch is not turned on.
Off
No system power is
output.
This status occurs in the following cases:
• The power module is faulty.
• A system input power cable connection problem
occurs.
• The external power supply is unavailable.
SYS FAN
Green
The fans are operating
correctly.
N/A
Red
The fans are operating
abnormally.
This status occurs in the following cases:
• A fan failure occurs.
• The system power switch is not turned on.
