Figure 3-6 Indicator
Lights
The six indicator lights on the front panel of the Gateway show module and
communication status, as described in the following paragraphs.
If the GA
TEWA
Y GOOD indicator is lit, it means that all power
-on/reset or
run-time diagnostic tests have been passed successfully. If the indicator is
flashing or not lit, one of the Gateway components has failed a diagnostic
test, and the Gateway is inoperable. If a reset does not remedy the
situation, you should return the unit for repair
.
The COMM ACTIVE indicator is lit continuously while any communication
is in progress. It is not lit while the Gateway is in T
est mode.
The ONLINE indicator is lit while the Gateway is communicating with the
network. However
, if you have taken the Gateway off-line by placing the
Online/Offline switch in the Offline position, the Online indicator will not be
lit at any time.
The RECEIVE indicator is lit when the Gateway is receiving data on either
port.
The TRANSMIT indicator is lit when the Gateway is transmitting data on
either port.
The
TEST MODE indicator lights when you press the Self-T
est button and
the Gateway is in T
est mode. The indicator remains lit while the diagnostic
tests are being performed, and flashes when they are successfully
completed.
