LAN Port: This port is used to connect your LAN. 1.2.3 Mounting Bracket The following figure describes the structure of the mounting bracket.
Chapter 2 Network Topology A typical network topology for the EAP is shown below. Figure 2-1 Typical Topology To deploy an EAP in your local network, a DHCP server is required to assign IP addresses to the EAP and clients. Typically, a router acts as the DHCP server. Ensure the EAPs are in the same subnet with the Controller Host in which the EAP Controller is installed.
Chapter 3 Management Mode 300Mbps Wireless N Access Point EAP110 and Wireless N Gigabit Access Point EAP120/EAP220 can either work under the control of the EAP Controller software or work independently as a standalone access point. When user establishes a large-scale wireless network, the management of every single AP in the network is complex and complicated. With the EAP Controller software, you can centrally manage the mass APs simply in a web browser.
TIPS: Proceed to the following chapters for information on using the EAP in standalone mode. EAP110 is taken as the example.
Chapter 4 Network On Network page you can configure the IP address of the standalone EAP. Figure 4-1 Network Page Dynamic/Static: By default, the EAP device obtains an IP address from a DHCP server (typically a router). Select Static to configure IP address manually. Fallback IP: If the EAP fails to get a dynamic IP address from a DHCP server within ten seconds, the fallback IP will work as the IP address of the device.
