Wired/Wireless Access Switching
The wireless switching centralized architecture is composed of a DES-1228P PoE switch, which is the core unit that
manages the network, and multiple DWL-3140AP access points, which deliver wireless connectivity to mobile clients and
can be dispersed throughout the network. The Smart WLAN Manager provides each AP with configuration and security
profiles to intel igently manage data traversing the wireless waves.
Centralized WLAN Management & Easy
Through a centralized management platform, network maintenance and configuration become a more efficient process. If
any access point were to fail, administrators can instantly identify the location of the failed AP and immediately swap it out
with another AP. The switch wil automatical y configure the new AP with the same configuration as the previous unit.
Maximum Network Protection
Each client connecting to the wireless network goes through an authentication process to ensure maximum security.
Whether the client is an assigned user, a visiting guest, or just has department access, the system protects the
entire network infrastructure with its numerous security protocols. These protocols include WEP data encryption,
WPA/WPA2 and 802.1x user authentication security.
Gigabit Support for Network Backbone/Server
The PoE switch’s Gigabit ports al ow the wireless network to integrate with the network backbone and servers. These
ports support combo 10/100/1000BASE-T and SFP connections, providing the flexibility for instal ing copper and fiber

For instal ation sites, access points typical y need to be placed at out-of-the-way locations such as on the ceilings or
rooftops for maximum coverage. It is at these locations where wal AC outlets are inaccessible, and extending power lines
to these places is difficult and expensive. By transmitting remote power through the standard network cabling inside the
