Follow below troubleshooting steps to resolve this:

1. Firmware Upgrade:
The primary solution is to upgrade the LOM firmware to version 3.11. This upgrade has been specifically designed to address the reported issue. Please follow your organization's standard procedures for firmware updates.

2. Power Cycle:
If the firmware upgrade does not resolve the issue, a power cycle may be necessary.
Carefully disconnect the power cable from the affected device.
Wait for a minimum of five (5) minutes.
Reconnect the power cable.

3. Contact Technical Support:
If the issue persists after both the firmware upgrade and power cycle, it indicates a potential hardware failure. Please contact technical support for further diagnosis and to initiate the RMA process.
