Diagnosing Pluggable Transceivers; Displaying And Maintaining Device Management Configuration - 3Com 4500G Family Configuration Manual

To do...
Display key parameters of the
pluggable transceiver(s)
Display part of the electrical
label information of the
anti-spoofing transceiver(s)
customized by H3C
You can use the Vendor Name field in the prompt information of the display transceiver
command to identify an anti-spoofing pluggable transceiver customized by H3C. If the field is H3C,
it is considered an H3C-customized pluggable transceiver.
Electrical label information is also called permanent configuration data or archive information,
which is written to the storage component of a board during device debugging or testing. The
information includes name of the board, device serial number, and vendor name or name of the
vendor who customizes the transceiver.

Diagnosing pluggable transceivers

The system outputs alarm information for you to diagnose and troubleshoot faults of pluggable
transceivers. Optical transceivers customized by H3C also support the digital diagnosis function, which
monitors the key parameters of a transceiver, such as temperature, voltage, laser bias current, TX
power, and RX power. When these parameters are abnormal, you can take corresponding measures to
prevent transceiver faults.
Follow these steps to diagnose pluggable transceivers:
To do...
Display the current alarm
information of the pluggable
transceiver(s)
Display the currently measured
value of the digital diagnosis
parameters of the anti-spoofing
optical transceiver(s)
customized by H3C
