command to display the key parameters of
transceiver modules, including the transceiver module type, connector type, central wavelength of
the transmit laser, signal transmission distance, and vendor name.

Diagnosing transceiver modules
The router provides the alarm and digital diagnosis functions for transceiver modules. When a
transceiver module fails or is not operating correctly, you can perform the following tasks:
•
Check the alarms on the transceiver module to identify the fault source.
•
Examine the key parameters monitored by the digital diagnosis function, including the
temperature, voltage, laser bias current, TX power, and RX power.

Saving the running configuration
IMPORTANT:
You must save the running configuration to a .cfg configuration file.
You can use one of the following methods to save the running configuration:
•
Fast mode
—Use the
save
command without the
safely
keyword. In this mode, the router
directly overwrites the target next-startup configuration file. If a reboot or power failure occurs
during this process, the next-startup configuration file is lost. You must specify a new startup
configuration file after the router reboots.
