Use this information to solve problems related to optional devices.
External USB device not recognized
Make sure that the proper drivers are installed on the compute node. See the product documentation for the USB device for information about device drivers.
Use the Setup utility to make sure that the device is configured correctly.
If the USB device is plugged into a hub or the console breakout cable, unplug the device and plug it directly into the USB port on the front of the compute node.
PCIe adapter is not recognized or is not functioning
Complete the following steps until the problem is resolved:
Check the event log and resolve any issues related to the device.
Validate that the device is supported for the server (see Lenovo ServerProven website).
Make sure that the adapter is installed in a correct slot.
Make sure that the proper device drivers are installed for the device.
Resolve any resource conflicts if running legacy mode (UEFI).
Check Lenovo Data Center Support for any tech tips (also known as retain tips or service bulletins) that might be related to the adapter.
Ensure any adapter external connections are correct and that the connectors are not physically damaged.
Insufficient PCIe resources are detected.
If you see an error message stating “Insufficient PCI Resources Detected,” complete the following steps until the problem is resolved:
Remove one of the PCIe adapters.
Restart the system and press F1 to display the Lenovo XClarity Provisioning Manager system setup interface.
Click; then, modify the setting to the lower memory capacity. For example, modify 3 GB to 2 GB or modify 2 GB to 1 GB.

If the device comes with test instructions, use those instructions to test the device.
If the failing device is a SCSI device, make sure that:
The cables for all external SCSI devices are connected correctly.
The last device in each SCSI chain, or the end of the SCSI cable, is terminated correctly.
Any external SCSI device is turned on. You must turn on an external SCSI device before you turn on the server.
Reseat the failing device.
Replace the failing device.
