Software Checklist

Software Checklist 4
Please make sure that you have purchased and/or own licenses to install and use the DHCP
server and TFTP server software.
WARNING:
The circuitry in the 4600 Series IP Telephones reserves IP addresses of the form
192.168.2.x for internal communications. The telephone(s) will not properly use addresses
you specify if they are of that form.
Required Network Information 4
DHCP is the control point where an enterprise controls its IP Telephones. Before administering
DHCP and TFTP, complete the information in Table4-2 below to ensure that you have the
necessary information regarding your network. There may be more than one Gateway, TFTP
server, subnet mask and CLAN in your configuration. You will need a copy of this table for each
DHCP server.
Release 1.5 of the 4600 Series Telephones supports the ability to specify a list of IP addresses for
a gateway/router, TFTP server, and DEFINITY® CLAN board(s), as explained in Chapter 2, IP
Address Lists and Station Number Portability Each list may contain up to 127 total ASCII
characters, with IP addresses separated by commas with no intervening spaces.
When specifying IP addresses for the TFTP server or call server, you can use either dotted
decimal format ("xxx.xxx.xxx.xxx") or DNS names to identify the address(es). If you use DNS, note
that the system value DOMAIN will be appended to the IP addresses you specify. If DOMAIN is
null, the DNS names must be fully qualified, in accordance with IETF RFCs 1034 and 1035. For
more specific information about DNS, see DHCP Generic Setup (page 4-7) and DNS Addressing
(page 4-24).
It is possible to install both the DHCP server and the TFTP server on the same
machine.
