IO Power OK Indicates that the I/O controller is on and receiving DC power from the router
midplane. This LED comes on during a successful router boot and remains on
during normal operation of the router.
Enabled Indicates that the network processing engine and the I/O controller are
enabled for operation by the system; however, it does not mean that the Fast
Ethernet port on the I/O controller is functional or enabled. This LED comes
on during a successful router boot and remains on during normal operation of
the router.
FE Enable Indicates that the Fast Ethernet port on the I/O controller is initialized and
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.
FE Link Indicates that the Fast Ethernet port on the I/O controller has established a
valid link with the network. This LED remains off during normal operation of
the router, unless there is an incoming carrier signal.
MII EN 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
controller has been enabled and the MII port has been configured as the media

the Fast Ethernet port). This LED remains on during normal operation of the
router.
RJ45 EN Indicates that the Fast Ethernet port’s RJ-45 port (the default media type for
