Troubleshooting A-3
Observing LED Behavior
No console login prompt is
displayed. Terminal settings are incorrect
or a connection or cable is
inoperable. • Verify terminal settings of
9600 baud, 8 data bits, 1
stop bit, a parity of none,
and software control
(XON/XOFF).
• Verify that DIP switch 1 is
up.
• Verify that you have a
working console cable and
that it is properly connected
at both ends. For cable
information, see “Console
Cable” on page D-2.
Link LED is solid off. If you are connected to an
10Base5 (AUI) Ethernet
transceiver, the Link LED
blinks only once at startup.
Link LED is not lit when
connected to a 10BaseT
Ethernet hub. There is no link integrity. Verify that DIP switch 3 is up
and that you have a working
10BaseT cable properly
connected to the Office Router
and to the hub. Turn the
power off and on to activate
the DIP switch setting.
Network LED is solidly lit. Heavy traffic can cause the
network LED to blink so
rapidly that it appears to be
solidly lit.
However, if packets cannot be
passed, you might have an
incorrectly cabled network. Verify that the network
cabling is correct.
Network LED is not lit. If the Office Router is not
receiving, or sending traffic,
the network LED is not lit. Verify that the network
cabling is correct.
