8: Status Light Behavior
UBox User Guide 61
Stage Status Troubleshooting
STAGE 3
Checking Ethernet
Connection
SYSTEM 2 and SYSTEM 3 (both
red/amber) start blinking while the
UBox looks for an Ethernet signal
(a physical Ethernet connection)
and continue to blink until the
UBox finds this signal.
STAGE 4
Finding IP Address
SYSTEM 2 and SYSTEM 3 (both
red/amber) blink while the UBox
tries to obtain an IP address. Once
the UBox obtains its IP address,
the UBox has finished booting and
is now running. The status lights
now have a new meaning. Please
refer to Figure 8-4. UBox Status
Lights -- UBox is Running.
Notes:
If the UBox is configured to
use a Static IP address,
Stage 4 finishes immediately.
For DHCP only, it waits for
the DHCP UBox.
For Zeroconfig only, it takes
1-2 seconds while it
negotiates.
For Default, it waits for DHCP
for 10 seconds before taking
a Zeroconfig address (1-2
seconds).
If SYSTEM 2 and 3 never stop
blinking, the UBox is not finding a
valid Ethernet connection, or you
have configured the UBox to use
an invalid IP address.
