LED Status Meaning Analysis
Off The fans do not work.
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.
PoE IN1
Green
The PoE power (PoE1)
is input correctly.
N/A
Red
A power input problem
occurs to PoE1. The input voltage of PoE1 is not in the rated voltage
range.
Off
No power of PoE1 is
input.
This status occurs in the following cases:
• The power module is faulty.
• An input power cable connection problem occurs to
PoE1.
• The external power supply is unavailable.
PoE IN2
Green
The PoE power (PoE2)
is input correctly.
N/A
Red
A power input problem
occurs to PoE2. The input voltage of PoE2 is not in the rated voltage
range.
Off
No power of PoE2 is
input.
This status occurs in the following cases:
• The power module is faulty.
• An input power cable connection problem occurs to
PoE2.
• The external power supply is unavailable.
PoE IN3
Green
The PoE power (PoE3)
is input correctly.
N/A
Red
A power input problem
occurs to PoE3. The input voltage of PoE3 is not in the rated voltage
range.
Off
No power of PoE3 is
input.
This status occurs in the following cases:
• The power module is faulty.
• An input power cable connection problem occurs to
PoE3.
• The external power supply is unavailable.
PoE OUT
Green
The PoE power is output
correctly.
N/A
Red
A PoE 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 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.
• An input power cable connection problem occurs to
PoE1, PoE2, and PoE3.
• The external power supply is unavailable.
