The 3Com 3100 Entry Telephone does not have a display panel to show
the status of the process of initializing the telephone when you connect it
to an NBX system or when you reboot the phone of the NBX system.
However, the 3100 Entry Telephone indicates its status by displaying a
series of blinking patterns using its message waiting indicator light.
Table 30 describes the 3100 Entry Telephone initialization states.

2 blinks in 2 seconds
Pause 2 seconds

The 3100 is searching for
an NBX system using a
Layer 2 protocol No action required. If the
3100 does not find an NBX
system using Layer 2, it will
search for an NBX system
using a Layer 3 protocol.
3 blinks in 3 seconds
Pause 2 seconds
Repeat
The 3100 is searching for
an NBX system using a
Layer 2 protocol The 3100 will start using
Layer 3 after it has received IP
configuration information
from a DHCP server.
Continuous slow blinks
with no pause The 3100 has detected
an NBX system using a
Layer 2 protocol. If this pattern persists, it
could indicate that the device
is not in the NBX database.
You should use the NBX
NetSet utility to add the
device to the system.
3 blinks in 1.5 seconds
Pause 2 seconds
Repeat
The 3100 is trying to
obtain IP information
from a DHCP Server.
If it is successful the
pattern will change to
Layer 3 Discovery. If
DHCP configuration fails
then the 3100 pattern
will temporarily indicate
DHCP Failure, described
below.
If this state persists for 20 or
more seconds then the
device is not able to detect a
DHCP server.
If this state ends and the
device transitions to DHCP
Failure, and the device is
expected to utilize DHCP,
then the DHCP offer is
incorrect or missing
Option-184 information.
Correct the DHCP
configuration or program IP
information into the 3100
using the 3Com Telephone
Local Configuration tool,
which is described in the
NBX
Administrator’s Guide .
