REX extenders
are working, but
the USB 2 or USB
3 LEDs on the
LEX and REX are
blinking.
1. The LEX and/or REX is in
suspend mode. For a variety of
reasons, the host computer
may place the LEX/REX into
suspend mode. Typically, it
is because there are no USB
devices attached, the USB
device is asleep, or the host
computer is in a sleep state or
hibernating.
1. Recover/resume the operating system from
sleep or hibernate modes (refer to your
operating system’s documentation).
2. Connect a USB device to the REX.
3. Use the connected device.
