operating
properly.

which will prevent
the board from
operating.

Error Condition/
Recommended Action
If off, or on and not
flashing, the board has a
problem.
Press the reset button on
the EMME front panel to re-
initialize the board. If the
board does not re-
initialize, it has probably
failed. Call Cabletron
Technical Support.
If on, a hardware error has
occurred.
Try re-initializing the board
by pressing the reset
button. If the LED is still lit,
call Cabletron Technical
Support.
Data loop condition exists.
Reconfigure the network to
remove the data loop.
