enabled for operation by the system. This LED comes on after the I/O
controller has been enabled and remains on during normal operation of the
router.

valid link with the network. This LED remains off during normal operation of
the router, unless there is an incoming carrier signal.
Indicates that the Fast Ethernet port's MII ports is initialized and enabled by
the system, and configured for operation. This LED comes on after the I/O
