Troubleshooting transceiver modules 

The system outputs alarm information for you to locate and troubleshoot faults of transceiver 
modules. 

To display the alarming information or fault detection parameters of a transceiver module:

Rebooting the device 

 

CAUTION: 

•

  If the main system software image file does not exist, do not use the 

reboot

 command to reboot 

the device. Specify the main system software image file first, and then reboot the device. 

•

  The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the device 

prompts "REBOOT IN ONE MINUTE" and reboots in one minute. 

•

  If you are performing file operations when the device is to be rebooted, the system does not 

execute the reboot command for security. 

 

To reboot a device, use one of the following methods: 

•

 

Use the 

reboot

 command to reboot the device immediately. 

•

 

Enable the scheduled reboot function at the CLI. You can set a time at which the device can 
automatically reboot, or set a delay so that the device can automatically reboot within the delay. 

•

 

Power on the device after powering it off, which is also called hard reboot or cold start. As a best 
practice, do not use this method because it might cause data loss and hardware damages. 

To reboot the device immediately:
