DAP controller software 127
The DAPs can be installed in an IP environment without a DHCP server, a
TFTP server, or both. Such an IP environment can be a VLAN within the
company network where the IT manager does not allow a DHCP server.
This IP environment can also be a branch office where a few DAPs are
installed, without a DHCP server.
If a DAP must operate without a DHCP server, a TFTP server, or both, the
DAP requires that the IP address and configuration data are stored in the
DAP on a semipermanent basis, in FEPROM.
Storing the data on the DAP requires a DHCP server and a TFTP server
once only. The DHCP and TFTP server can be on a stand alone PC with a
network interface and a DAP connected. The DHCP and TFTP server can
also be on any other computer in the network.
The DHCP server and TFTP server are required while you configure the
DAP, but are not required during normal operation.
ATTENTION
To store the data in the DAP, it is necessary that the DAP get a DHCP offer with
an Unlimited or Infinite lease. Ensure the DHCP server issues an Unlimited or
Infinite lease. The DHCP server that comes with IP DECT Release 4 issues
such a lease by default.
If an MS Windows DHCP server is configured, follow the steps in the next
procedure to enable unlimited lease.
