Solution; 10-Gigabit Sfp+ Fiber Port Fails To Come Up; Symptom - HP FlexFabric 12900 series Troubleshooting Manual

Solution

To resolve the problem:
1. Verify that the speed and duplex mode of the local port match the speed and duplex mode of the
peer port:
a. Execute the display interface brief command to examine whether the speed and duplex mode
of the port match the speed and duplex mode of the peer port.
b. If they do not match, use the speed command and the duplex command to set the speed and
duplex mode for the port.
2. Verify that the speed and duplex mode of the port match the speed and duplex mode of the
transceiver module:
a. Execute the display interface brief command to examine whether the speed and duplex mode
of the port match the speed and duplex mode of the transceiver module.
b. If they do not match, use the speed command and the duplex command to set the speed and
duplex mode for the port.
3. Verify that the transceiver module is operating correctly:
a. Execute the display transceiver alarm interface command to check for alarms on the
transceiver module.

−
b. Use an optical power meter to verify that the Tx power and Rx power of the transceiver module
are stable and are within the correct range.
c. Execute the display transceiver interface command to verify that the local transceiver module
has the same wavelength and transmission distance as the peer transceiver module.
d. If the transceiver module is not operating correctly, replace it with a new HP transceiver module
that matches the fiber port.
For more information about transceiver modules, see the installation guide for the switch.
4. Replace the fiber with a new one to verify that the fiber is in good condition.
5. Replace the local port with a new one (on a card of the same type, if possible) to verify that the
local port is operating correctly.
6. Replace the peer port with a new one (on a card of the same type, if possible) to verify that the peer
port is operating correctly.
7. If the problem persists, contact HP Support.

10-Gigabit SFP+ fiber port fails to come up

Symptom

A 10-Gigabit SFP+ fiber port fails to come up.
The device displays None if no error has occurred.
The device displays alarms if the transceiver module has failed or if the type of the
transceiver module does not match the port type.
