Green
LED flashes to
indicate that a
segment is
transmitting a
frame.
If not connected to
the LAN, the LED
flashes every two
seconds to indicate
the device is
transmitting BPDU
frames.
If none of the transmit LEDs
are flashing, the EMM-E6 is
not transmitting frames on
any of the segments.
Ensure that the network is
actually producing Ethernet
traffic. Contact Cabletron
Systems Technical Support
for assistance.
CLN
Red
Collision detected
on a segment.
When the LAN is
operating properly,
occasional flashing
is normal.
Excessive flashing, or a solid
light, indicates an inordinate
number of collisions.
Ensure that the SQE test is
disabled for any transceiver
connected to the EMM-E6
external channels (D, E, or
F). Check cabling for data
loops or defective cables.
