button to save the LAN IP address.
If you change the LAN IP address, the connection will be terminated.
4. Reconfigure your PCs, if necessary, so that their IP addresses place them in the same subnet as
the new IP address of the LAN port. See the Quick Start Guide chapter, “Part 2 — Configuring
Your Computers,” for instructions.
5. Log into Configuration Manager by typing the new IP address in your Web browser’s
address/location box.
5.2 DHCP (Dynamic Host Configuration Protocol)
5.2.1 Introduction
5.2.1.1 What
is
DHCP?
DHCP is a protocol that enables network administrators to centrally manage the assignment and distribution of
IP information to computers on a network.
When you enable DHCP on a network, you allow a device — such as the RX3041H — to assign temporary IP
addresses to your computers whenever they connect to your network. The assigning device is called a
DHCP
server
, and the receiving device is a
DHCP client
.
Note
If you followed the Quick Start Guide instructions, you either
configured each LAN PC with an IP address, or you specified that
it will receive IP information dynamically (automatically). If you
chose to have the information assigned dynamically, then you
configured your PCs as DHCP clients that will accept IP
addresses assigned from a DCHP server such as the RX3041H.
The DHCP server draws from a defined pool of IP addresses and “leases” them for a specified amount of time
to your computers when they request an Internet session. It monitors, collects, and redistributes the addresses
as needed.
On a DHCP-enabled network, the IP information is assigned
dynamically
rather than
statically.
A DHCP client
can be assigned a different address from the pool each time it reconnects to the network.
5.2.1.2
Why use DHCP?
DHCP allows you to manage and distribute IP addresses throughout your network from the RX3041H. Without
DHCP,
you would have to configure each computer separately with IP address and related information. DHCP
is commonly used with large networks and those that are frequently expanded or otherwise updated.
