Verifying and diagnosing transceiver modules

Verifying transceiver modules

You can use one of the following methods to verify the genuineness of a transceiver module:
•
Display the key parameters of a transceiver module, including its transceiver type, connector
type, central wavelength of the transmit laser, transfer distance, and vendor name.
•
Display its electronic label. The electronic label is a profile of the transceiver module and
contains the permanent configuration, including the serial number, manufacturing date, and
vendor name. The data is written to the transceiver module or the device's storage component
during debugging or testing of the transceiver module or device.
The device regularly checks transceiver modules for their vendor names. If a transceiver module
does not have a vendor name or the vendor name is not HPE, the device repeatedly outputs traps
and log messages. For information about logging rules, see Network Management and Monitoring
Configuration.
To verify transceiver modules, execute the following commands in any view:
Task

Remarks
To view the default settings, use
the undo temperature-limit
command to restore the defaults
and then execute the display
environment command.
The high-temperature alarming
threshold must be higher than the
high-temperature warning
threshold, and the
high-temperature warning
threshold must be higher than the
low-temperature threshold.
Remarks
