packets will not
be forwarded as
the Spanning
Tree Algorithm
has put the
corresponding
Bridge Port into
a standby mode
due to detecting
a data loop
condition. Network Management has
placed the EMM-E6 in a
Standby condition; a data loop
condition exists.
Check with your Network
Administrator to find out if the
EMM-E6 was placed in
Standby on purpose.
If a Data loop does exist,
reconfigure the network to
remove the data loop.
RCV
A,B,C,D
(Receive) Yellow LED flashes to
indicate that a
segment is
receiving a
frame. If none of the receive LEDs is
flashing, the EMM-E6 is not
receiving frames on any of the
segments.
Check that each module is
firmly installed in the MMAC.
Ensure that all connected ports
are enabled.
