7 In the IP Settings dialog box, specify the IP settings for this device. The IP
Settings dialog box shows two groups of IP settings:
IP Settings Reported by Device — Typically, if you are configuring a
■
new telephone, you see 0.0.0.0 in each of the IP address, Default
Gateway, and Subnet Mask fields. Note that if a telephone has an IP
address, default gateway, and subnet mask, you cannot change those
values using the NBX NetSet utility.
Manually Assigned IP Settings — Use these fields to configure the
■
IP settings for the telephone. You can change an IP setting only if the
corresponding field under IP Settings Reported by Device is 0.0.0.0. If
the field contains a value other than 0.0.0.0, you can change the
value only through the telephone buttons. See the next section.
Manually assigned settings take precedence over settings assigned
automatically by DHCP. If you manually enter the IP settings for a
telephone using the telephone key pad, these settings replace any
settings supplied by a DHCP server, and the telephone no longer searches
for a DHCP server when it is plugged into a network.
8 Click OK.
The Ethernet (Layer 2) communications between the NCP and the
telephone ensure that the telephone receives the IP address of the NCP as
part of the configuration.
You can program IP configuration directly into a telephone using the
telephone Local User Interface (LUI) utility.
You can start the LUI utility on any 3Com telephone by cycling power to
the telephone, and then starting the utility before the telephone finishes
its download sequence. Each telephone has a different method of
starting the LUI utility:
