or initialization failure.

Solution
Try power cycling the switch. If the fault indication reoccurs:
• There may be a port configuration mismatch where a 10G transceiver is
installed in a port configured for 25G, or the reverse.
• A 10GBase-T transceiver may be installed in an incompatible port. See
Table 6 for list of supported ports.
• The transceiver may have failed.
• The switch port may have failed.
Check the switch Event Log and show interface command output for
indication of the fault condition.
If the port has an SFP/SFP+/SFP28 transceiver or QSFP+/QSFP28
transceiver installed, verify that the transceiver is supported by the switch.
Unsupported or unrecognized transceivers will be identified with this fault
condition. For a list of supported transceivers, see the ArubaOS-Switch and
ArubaOS-CX Transceiver Guide at https://asp.arubanetworks.com/
downloads.
The port group speed settings may not match the transceiver. Use the switch
console to see how the port group speed is configured. For more on port
group speed settings, see "Interface-Group operation".
The transceivers are also tested when they are "hot-swapped"—installed or
changed while the switch is powered on.
To verify the port has failed, remove and reinstall the transceiver without
powering off the switch. If the port fault indication reoccurs, you will have to
replace the transceiver. Check the event log to see why the transceiver failed.
If the fault indication persists after the transceiver has been removed, the
switch port is faulty and the switch will need to be replaced.
