Table 72 PSR650-A/PSR650-D power module status LED description
LED Status Meaning Analysis
Green
The power module is
working properly.
—
Red
The power module is
working 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.
Power module
status LED
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.
PSR1400-A power module status LEDs
The PSR1400-A power module provides three red-green status LEDs—power input LED (INPUT), power
output LED (OUTPUT), and fan LED (FAN).

LED Status Meaning Analysis
Green
The power is input
properly.
—
Red
A power input
problem occurs.
The input voltage is not in the rated voltage range.
INPUT
Off No power is input.
This status occurs in the following cases:
• The power module is faulty.
• A power cable connection problem occurs.
• The external power supply is unavailable.
Green
The power is output
properly.
—
Red
A power output
problem occurs.
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.
• The power module is not switched on.
OUTPUT
Off No power is output.
This status occurs in the following cases:
• The power module is faulty.
• A power cable connection problem occurs.
• The external power supply is unavailable.
