Configuring the DHCP
Server
If you choose to use DHCP, contact your network administrator to
configure the DHCP server. For an example, see Appendix C,
“Configuring Option 184 on a Windows 2000 DHCP Server,” in the
NBX Administrator’s Guide.
3C10165D E1 Digital Line Cards and 3C10116D T1 Digital Line Cards do
not support DHCP option 184. Before you install a 3C10165D E1 or
3C10116D T1 card at a site that is remote from the system’s NCP, you
must first initialize the card by connecting it to the same subnet as the
NCP.
3C10165D E1 Digital Line Cards and 3C10116D T1 Digital Line Cards do
not support DHCP lease times of less than 20 minutes.
Manually Configuring
Telephone IP Settings
For a telephone to work properly on a subnetwork separated from the
NCP, you must configure three IP settings (IP address, default gateway,
and subnet mask). You can use the NBX NetSet utility to manually
configure the settings, or you can enter the settings directly from the
telephone key pad.
To configure telephone IP settings with the NBX NetSet utility:
1 Connect the telephone to the same subnetwork as the NCP.
If the telephone has not already been discovered by the NCP, go to the
System Configuration - System Settings window and enable Auto
Discover Telephones .
2 Log in to the NBX NetSet utility using the administrator name and
password.
3 In the NBX NetSet - Main Menu window, click Device Configuration .
4 Click the Telephones tab.
5 Select the telephone from the Telephones list.
6 Click IP Settings . The Modify IP Settings dialog box appears. (The IP
Settings button does not appear unless you have enabled IP for the
system.)
