Switch and ATM Module are
operating normally.
Switch or ATM Module is either
downloading software or initializing,
(which includes a
Power On Self Test
).
Switch has failed its
Power On Self
Test (POST
)
ATM Module failed its

ATM port enabled; link present.
ATM port disabled; link present.
This LED will flash until all configured
LECs have successfully joined their
ELANs.
ATM agent software is not installed
correctly, or the ATM Module has
failed its POST (if the MGMT LED is
flashing yellow).
Switch has not recognized the ATM
Module.
The ATM Module is not installed, or a
link is not present on the ATM port,
or the ATM Switch is not on.

The ATM Switch has not
detected an error on the ATM
Module’s
transmit
link.
The ATM Switch at the far end
of the connection has detected a
problem with the ATM Module’s
transmit
connection, and
notified the ATM Module. For
example, the
transmit
half of the
ATM Module’s cable has been
disconnected at either the ATM
Module end or ATM Switch end
of the connection.
The cable between the ATM
Module and ATM Switch has
been disconnected.
Link Status

Green
OFF
A link is present on the ATM
port, and the port is receiving
valid SONET frames.
The Link is not present on the
ATM Port.
