700wl Series Overview
The 700wl Series system’s industry-leading cost-performance and uniquely flexible and scalable
deployment architecture provides the foundation for a secure, scalable, mission-critical 802.11 wireless
network. At the core of the wireless LAN (WLAN) the 700wl Series system provides key services
including centralized management and control, role-based fine-grained access policy enforcement,
secure Layer 3 roaming, and tiered layers of security, which enables companies to deploy and manage
802.11 networks ranging from tens to thousands of access points (APs).
A 700wl Series system consists of a central Access Control Server 740wl that provides services such as
authentication, roaming, and policy management, and one or more Access Controller units. Access
Controllers are gateway devices deployed at the edge of the network in the user data path enforcing
network authorization and business policy.
The Access Controller (a ProCurve Access Controller xl Module (J8162A) or a ProCurve Access
Controller 720wl) is a low cost, high-performance appliance with modular connectivity options that
require minimal configuration, and are deployed in conjunction with an ProCurve Access Control
Server 740wl. The Access Controller sits between the Wireless Access Points and the network, and
implements a powerful Packet Inspection Engine (Layer 2-7) that can rewrite and redirect client traffic
based on an Access Policy received from the Access Control Server. Each Access Policy is tailored to the
individual client based on who the client is (per a successful authentication) and where and when the
client has connected to the network.
The Access Control Server (the ProCurve Access Control Server 740wl and Access Controller xl Module
(ACM)) is a centralized resource on the network that provides services to the connected Access
Controllers such as authentication management, mobility management (roaming support), policy
management, and system monitoring and reporting. The Access Control Server is deployed as a
dedicated control function and does not sit in the user data path. A second Access Control Server can
be deployed in a redundant configuration to support stateful failover.
