Although the "Fault" orange LED on the host device front panel is not for this
HP AdvanceStack Internet Router only, the fault condition of the router is
OR'ed with the fault condition from other devices in the host and the host
itself. Therefore it is necessary to check all devices in the host device,
including this HP J3138A Internet Router, if the "Fault" orange LED on the
host device front panel is flashing.
