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.”
LEDs
Table 10 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
(yellow/green)
RPS
Steady green Both AC and DC inputs are normal.
Steady yellow
The AC input is abnormal or no AC input is
present, while the DC input is normal.
Off No DC input is present.
