Transceiver Module Failure; Symptom; Solution - HPE FlexNetwork 10500 SERIES Troubleshooting Manual

− If the Tx power reaches the limit, verify that the local transceiver module and fiber are
− If the Rx power reaches the limit, verify that the remote transceiver module and fiber are
2. If the port is a copper port, set the speed and duplex mode for the local and peer ports.
3. Verify that the link, peer device, and intermediate device are operating correctly.
4. If the problem persists, contact Hewlett Packard Enterprise Support.

Transceiver module failure

Symptom

A fiber port installed with a transceiver module cannot operate correctly.

Solution

To resolve the problem:
1. Execute the display transceiver alarm interface command to examine the alarms present on
the transceiver module.
If input errors occur, verify that the peer port, fiber, and intermediate device are operating

correctly.
If output errors, current errors, or voltage errors occur, verify that the local port is operating

correctly.
