Troubleshooting USB Devices
NOTE:
USB devices can be connected only to the blade front panel. Total length of
a USB cable should not exceed 3 m (9.8 ft).
Problem
• USB device or USB device cable
• Multiple devices connected directly to blade (powered USB hub not used)
• Blade
Action
1 Ensure that the blade(s) is turned on.
2 Check the USB device connection to the blade.
3 Swap the USB device with a known-working USB device.
4 Connect the USB devices to the blade using a powered USB hub.
5 If another blade is installed, connect the USB device to that blade. If the
USB device works with a different blade, the first blade may be faulty. See
