Displaying transceiver module information

Identifying transceiver modules

the transceiver modules. The key parameters include transceiver module type, connector type,
central wavelength of the laser sent, transmission distance, and vendor name.
To display transceiver module information:
Task
Display key parameters of the
transceiver module in a specific
interface.
Troubleshooting transceiver modules

modules.

Rebooting the firewall

CAUTION:
• If the main system software image file does not exist, do not use the reboot command to reboot
the firewall. Specify the main system software image file first, and then reboot the firewall.
• The precision of the rebooting timer is 1 minute. 1 minute before the rebooting time, the firewall
prompts "REBOOT IN ONE MINUTE" and reboots in one minute.
• If you are performing file operations when the firewall is to be rebooted, the system does not
execute the reboot command for security.
To reboot a firewall, use one of the following methods:
•
Use the reboot command to reboot the firewall immediately.
•
Enable the scheduled reboot function at the CLI. You can set a time at which the firewall can
automatically reboot, or set a delay so that the firewall can automatically reboot within the delay.
•
Power on the firewall 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 firewall immediately:
Task
Reboot the firewall immediately.
