Installation
When you initialize a telephone by enabling the Auto Discover feature
(see
“Using Auto Discover for Initial System Configuration” on
page 112 ), the display panel on the telephone shows several messages.
After the initialization is complete, the display panel shows the current
system date and time and the telephone’s extension. Pick up the handset
and listen for dial tone.
The 3100 Entry Telephone does not have a display panel. To verify
successful initialization of a 3100 Entry Telephone through Auto Discover
feature:
1 Login to the NBX NetSet utility as administrator and then click Telephone
Configuration > Telephones .
2 Verify the MAC address listed in the Telephones list against the MAC
address printed on the label on the bottom of the telephone.
3 Make note of the extension assigned to the telephone.
4 Use another NBX telephone on the system to call the Entry telephone.

The 3100 has detected
more than one NBX
system on the local
subnet and does not
have information to
select the correct one. Configure the network
correctly so that only a single
NBX system is on the subnet.

New pattern
The 3100 was unable to
get information from a
DHCP server. If this occurs within the first
minute (typically in the first
10 to 20 seconds) of
searching for a DHCP server
then a DHCP Offer was
received from the server but
it did not contain valid or
complete information.
If this state occurs after a
minute or more of searching
for a DHCP server then no
DHCP Offer was received.
