TSRX-2xx/8 module troubleshooting
Ordinary troubleshooting procedures which can be carried out on TMRX-200 module first involve
a check of the optical adapters status and of the fiberoptics cables. If the alarm status still persists,
a reboot of both the TMRX-200 module and of the TSRX-2xx/8 module can be performed so as to
verify if the problem depends on a failed modem connectivity.
Quick TSRX-2xx/8 troubleshooting procedure
(The following procedure is summarized by the flow-chart in fig. 5.34c)
In case the red LED is ON, please follow these steps:
1. Clean the optical adapter
2. If the problem still persists, refer to the fibre optic DL troubleshooting so as to check if the
optical cable or optical connection has any problem on DL path
3. If previous actions didn’t make the LED switch off, a reboot of both the TSRX-2xx/8
module and of the TMRX-200 module (on the master side) could be performed so as to test
modem connectivity.
4. If the red LED still remains on, please check the alarm status by the LMT or the supervision
unit in order to better understand the problem and its possible solution.
