(Transmit)
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 it is
transmitting
BPDU frames.
If none of the transmit LEDs is
flashing, the EMM-E6 is not
transmitting frames on any of
the segments.
Contact Cabletron Technical
Support for assistance.
CLN
(Collision)
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’s
external channels (D, E, or F).
Check cabling for data loops or
defective cables.
