The 5600MSC rear panel is fitted with two LEDs to monitor the Ethernet connection.
10/100
This Amber LED is ON when a 100Base-TX link is last detected. The LED is OFF when
a 10Base-T link is last detected (the LINK LED is ON). Upon power-up the LED is OFF
as the last detected rate is not known and therefore defaults to the 10Base-T state until
rate detection is completed.
LN/ACT
This dual purpose Green LED indicates that the 5600MSC has established a valid
linkage to its hub, and whether the 5600MSC is sending or receiving data. This LED will
be ON when the 5600MSC has established a good link to its supporting hub. This gives
you a good indication that the segment is wired correctly. The LED will BLINK when the
5600MSC is sending or receiving data. The LED will be OFF if there is no valid
connection.
