NOTE:
•
Before you connect a networking device by using optical fibers, make sure that the fiber
connectors work with the transceiver modules.
•
Before connecting fiber cables, make sure that the optical power of the receiver end
does not exceed the upper threshold of the receiving optical power of the transceiver
module; otherwise, the transceiver module may be damaged. For the optical power
specifications of the receiver end, see the chapter “Appendix B Transceiver module
specifications.”

LED description
LED Mark
Status Description
Power status LED
(green/yellow/red)
PWR
Steady green
The system is going through the power on self
test (POST) or downloading software.
Flashing green (1 Hz)
The system is working properly.
Steady red
The system failed to pass the POST or has
detected a serious fault.
Steady yellow (1 Hz)
At least one port has failed the POST or
detected a minor fault.
Off
No AC input is present.
PoE/PoE+ status LED
(green/yellow)
Mode
Steady green
The PoE/PoE+ is operational.
Flashing green (3 Hz)
PoE/PoE+ supply is not available because the
maximum output power of the port is exceeded
or the remaining power is insufficient.
Steady yellow
The ports cannot provide PoE/PoE+ supply due
to an over-temperature, over-voltage, or
under-voltage protection shutdown of the
PoE/PoE+ system.
Flashing yellow (3 Hz)
At least one port failed to pass the POST; if the
PoE sub-board is in position, it may be caused
by a UART communication failure or some other
self test failure.
Off
No PoE/PoE+ supply.
RPS status LED
RPS
Steady green
Both AC and DC inputs are normal.
