LAN1/LAN2/LAN3/LAN4 LEDs

The Ethernet ports (located beside the
VGA port) have two LEDs. On each Gb
LAN port, one LED blinks to indicate
activity while the other may be green,
amber or off to indicate the speed of
the connection. See the table on the
right for the functions associated with
the connection speed LED.

IPMI Dedicated LAN LEDs

In addition to LAN Ports 1/2, an IPMI
Dedicated LAN is also located on
the I/O Backplane. The amber LED
on the right indicates connection
and activity; while the green LED on
the left indicates the speed of the
connection. See the tables at right for
more information.
