Displaying transceiver module information
Identifying transceiver modules
To identify transceiver modules, you can use the following command to view the key parameters of
the transceiver modules. The key parameters include transceiver module type, connector type,
central wavelength of the laser, transmission distance, and vendor name.
To display transceiver module information, execute the
display transceiver interface
[
interface-type interface-number
] command.
Troubleshooting transceiver modules
The system outputs alarm information for you to locate and troubleshoot faults of transceiver
modules.
To display the alarm information about transceiver modules, execute the

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 the device, use one of the following methods:
•
Use the
reboot
command to reboot the device immediately.
•
Schedule a reboot to occur at a specific time or date or after a delay by using the
schedule
reboot
command.
•
Power cycle the device. This method cuts off the power of the device forcibly, which might
cause data loss or hardware damage. It is the least-preferred method.
