When replacing an expansion board on a BitLocker-encrypted server, always disable BitLocker before
replacing the expansion board. If BitLocker is not disabled, the system requests the recovery method
selected when BitLocker was configured. Failure to provide the correct recovery password or passwords
results in loss of access to all encrypted data.
Be sure to enable BitLocker after the installation is complete.

Network controller or FlexibleLOM issues
Network controller or FlexibleLOM is installed but not working
Symptom
The network controller or the FlexibleLOM is not working.
Action
1.
Check the network controller or FlexibleLOM LEDs to see if any statuses indicate the source of the
issue. For LED information, see the network controller documentation or server documentation.
2.
Review the IML for error messages that could indicate the issue.
3.
Be sure no loose connections exist.
4.
Be sure the correct cable type is used for the network speed or that the correct SFP or DAC cable is
used. For dual-port 10 GB networking devices, both SFP ports should have the same media (for
example, DAC cable or equivalent SFP+ module). Mixing different types of SFP (SR/LR) on a single
device is not supported.
5.
Be sure the network cable is working by replacing it with a known functional cable.
6.
Be sure a software issue has not caused the failure. For more information, see the operating system
documentation.
7.
Be sure the server and operating system support the controller. For more information, see the
operating system documentation or server documentation.
8.
Be sure the controller is enabled in the UEFI System Utilities.
9.
Be sure the server ROM is up to date.
10.
Be sure the controller drivers are up to date.
11.
Be sure a valid IP address is assigned to the controller and that the configuration settings are
correct.
