If you have any problems during installation and using, try to solve them by the following proposals.
If there is no solution, please contact with distributors for technical support.
Answer: PS faults. Check if PS working properly and –48 PS connection is not reverse.
Answer: Loss of receiving signal occurs at optical port. Check if the input fiber is connected well
and if there is reverse in connection. Check the received optical power using optical power meter, it
should be greater than receiving sensitivity.
Answer: Loss of frame of receiving signal at optical port. In this case, optical signal has received, but
the optical power may be about critical value of sensitivity. Check RX optical power to ensure if it
connects well at remote optical TX port.
Answer: The bit error of optical RX signal is greater than 10
well and RX optical power.
Answer: The bit error of optical RX signal is greater than 10
just after turning on the power, after about 10 seconds, the E-6 indicator will be off. If there is E-6
alarm during operation process please check if optical RX port connects well and test RX optical
power.
Answer: Firstly check if the Ethernet cable is well connected or not. And then whether the other end
device works normally. At last check the cable referring to section 6.2.
Answer: Check whether the E1 cable and fiber are well connected, and then check the E1 LOS alarm
indicator on front panel. At the same time use the loop-back function which is provided by Bit4 of
SEL dip-switch to confirm the problem position.
Answer: Loss alarm of RX signal at E1 channel, there is no HDB3 signal received. Check if it
connects well at E1 port; if the connection of 75 Ω cable reverse and if the string of 75 Ω cable in
right order. If there is LOS alarm of unused E1 tributary, can press "mask" button to "on" to make
alarm after configuration of device.
