These aren’t plenum-rated solutions. Don’t route multiple USB-XT extension cables where
they aren’t accessible, for example, inside walls or ceilings.
l
USB cable length must not exceed 16' (5 m). See USB connectors and cables on page 19
l
The computer’s USB interface must provide sufficient power for the bus-powered extension
cables. A laptop might not provide sufficient power while running on battery power.
l
Don’t connect more than three USB-XT extension cables. The combined length of the
extender cables results in too much voltage drop to power another extender.
