Diagnosing Transceiver Modules; Saving The Running Configuration - H3C SR6602-I Installation Manual

Diagnosing transceiver modules

The device 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.
To diagnose a transceiver module:
Task
Display transceiver alarms.
For more information about transceiver module-rated commands, see the command references for
the device.

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
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 device reboots.
•
Safe mode—Use the
mode, but more secure. In safe mode, the system saves the configuration in a temporary file and
starts overwriting the target next-startup configuration file after the save operation is complete. If
a reboot or power failure occurs during the save operation, the next-startup configuration file is
still retained. Use the safe mode if the power source is not reliable or you are remotely
configuring the device.
To save the running configuration:
Task
Save the running configuration to a
configuration file, without specifying the file
as a next-startup configuration file.
Save the running configuration to a
configuration file in the root directory of the
storage medium, and specify the file as a
next-startup configuration file.
