SpectraLink 8020/8030 Wireless Telephone: Administration Guide for SRP
28 1725-36030-001_B.doc
Static IP Allows you to manually set a fixed IP address. If selected, the
handset will prompt for the IP addresses for each configurable
network component. When entering addresses, enter the digits only,
including leading zeroes. Do not enter punctuation.
Regardless of the mode in which the handset is operating, the
following components must be configured:
Phone IP The IP address of the handset. This is automatically assigned
if DHCP is used. If using Static IP configuration, you must obtain a
unique IP address for each handset from your network administrator.
Default Gateway and Subnet Mask Used to identify subnets, when using
a complex network which includes routers. Both of these must be
configured either with an IP address under Static IP (not set to
000.000.000.000 or 255.255.255.255) or with DHCP for the handset to
contact any network components on a different subnet. If configured
on the DHCP server, use option 3 for the Default Gateway and option
1 for the Subnet Mask. Contact your network administrator for the
proper settings for your network.
SpectraLink 8020/8030 Wireless Telephones cannot roam with
uninterrupted service between subnets unless specific LAN
components are present. Certain AP/Ethernet switch combinations
establish a layer-2 tunnel across subnets that enables the handsets
to roam. Without this capability, any call in progress will be dropped
when the user moves out of range and the handset must be power
cycled in order to resume functionality in the new subnet area.
Ensure that all your APs are attached to the same subnet for proper
operation. The handset can change subnets if DHCP is enabled
and the handset is powered off then back on when within range of
APs on the new subnet.

Practices for detailed configuration information.
TFTP Server IP The IP address of a TFTP server on your network which
holds software images for updating the wireless telephones. If this
feature is configured (not set to 0.0.0.0 or 255.255.255.255) either via
Static IP configuration or using DHCP option 66 (TFTP server), or the
Boot server/next server (siaddr) field, the wireless telephone will
check for newer software each time it is powered on or comes back
into range of your network. This check takes only a second and
ensures that all wireless telephones in your network are kept up-to-
date with the same version of software.
Syslog Server IP The IP address of the syslog server. See Chapter 5
Diagnostic Tools for more information.
