UEFI diagnostic program

A UEFI diagnostic program is preinstalled on the hub. It enables you to test memory modules and internal
storage devices, view system information, and check and recover bad sectors on internal storage devices.
To run the UEFI diagnostic program, do the following:
1. Turn on the hub. If the hub cannot be turned on, go to "Basic procedure for resolving hub problems" on
page 37. If an error code is displayed, go to "Symptom-to-FRU index" on page 32 for error code
descriptions and troubleshooting hints.
2. Repeatedly press and release the F10 key when turning on the hub. The main screen of the UEFI
diagnostic program is displayed.
3. Follow the instructions on the screen to use the diagnostic program.
The options on the main screen are as follows:
Solution
• Connect the USB cable from the USB connector to the USB
device. If the USB device has its own power cord, connect the
power cord to a grounded electrical outlet.
• Turn on the USB device and keep the device online.
• Install any device drivers or programs supplied with the USB
device. Refer to the documentation that comes with the USB
device for more information.
• Disconnect and reconnect the USB connector to reset the USB
device.
• Ensure that the Smart USB Protection function is disabled in UEFI
BIOS.
