DATA SHEET

OVERVIEW

The 3Com®Wireless 7760 11a/b/g PoE Access Point is a cost-effective

dual band, Power over Ethernet (PoE) wireless solution for small and

medium enterprises. Configurable, this access point can operate at IEEE

802.11a or can be used as an IEEE 802.11b/g access point.

With the latest advanced security features such as Wi-Fi Protected Access

(WPA/ WPA2), Wired Equivalent Privacy (WEP) and Open system this

access point (AP) provides ultra-fast speeds of up to 108 Mbps in turbo

mode and offers superior long-range connectivity with eXtended range

(XR) technology. This new access point also provides multiple SSID

support and VPN passthrough along with VLAN support.

KEY BENEFITS

ENABLE WIRELESS FREEDOM

Take advantage of the freedom of high-speed networking without wires

with this Wi-Fi CERTIFIED 3Com Wireless 7760 11a/b/g PoE Access

Point. WLANs are an attractive solution for cost-effectively and securely

extending mobile access to wired network resources and for creating

full-featured networks in small to medium businesses, remote sites or at

temporary locations.Each access point supports upto 64 wireless users,

allowing plenty of room for growth.

PROVIDE POE DEPLOYMENT FLEXIBILITY

PoE support makes it easier than ever to overcome installation problems

byeliminating the need for an AC power plug at each AP. The 3Com

Baseline Switch 2226-PWR Plus or other 802.3af-compliant PoE products

supplyboth power and data to the access points through Category 5 or

6Ethernet cable, giving you flexible installation options in hard-to-wire

or -reach locations.

KEY BENEFITS

(CONTINUED) SECURE AND PROTECT WIRELESS COMMUNICATIONS

3Com delivers enterprise-class security features to small and medium

businesses. To shield wireless communications at the source, WPA2

with TKIP/AES encryption provides the latest, toughest standards-based

security—WEP encryption supports legacy 802.11b wireless clients.

For additional protection, this access point supports IEEE 802.1X and

MAC address access control, authentication, and authorization through

backend RADIUS servers.

PROVIDE FLEXIBLE SECURITY AND ACCESS CONTROL

You can configure and store up to four SSIDs with different security

profiles for groups of users. IEEE 802.1Q-compliant VLAN support

works with the multiple SSID feature to control access to network

resources and segment user traffic.

SOLVE COMPLEX CONNECTIVITY PROBLEMS

The Wireless Distribution System bridging feature solves complex

wireless connectivity problems. The access point supports both

point-to-point and point-to-multipoint WDS links as well as repeater

and client bridge modes for flexible network deployment.

DELIVER ENTERPRISE-CLASS FEATURES

3Com delivers superior business value byoffering enterprise-class

solutions without the complexity. 3Com also backs each product with

global sales, service and support along with technology, financial and

operational strength.

SuperG mode.

Wi-Fi a/b/g CERTIFIED Helps ensure interoperability with Wi-Fi CERTIFIED products from other

vendors.

ROBUST SECURITY FEATURES

Encryption: WPA/WPA2, AES, TKIP Toughest industry-standard algorithms help keep wireless transmissions

and WEP private.

Multiple security profiles Store up to eight different security settings; up to four security profiles

can run at any time.

Multiple SSID support with SSIDs can be bridged together or isolated.

SSID isolation

Access control Screens device MAC addresses to ensure that only trusted clients gain

access to the WLAN.

802.1Q VLAN support Groups users according to data or traffic requirements to segment traffic

flow based on business priorities.

RADIUS server MAC-based and Centralizes wireless security through existing network RADIUS servers.

802.1X AAA support

Rogue AP detection and logging Identifies and logs unauthorized, potentially harmful APs for remedial

action.

3COM®WIRELESS 7760 11A/B/G POE ACCESS POINT

INSTALLATION AND MANAGEMENT CONVENIENCE

WDS bridge and repeater Multiple APs can function as bridges supporting point-to-point or multi-

configuration point modes; repeater mode extends wireless coverage.

PoE support Expands installation options by eliminating the need for power adapters

and AC outlets for APs.

Access Point Discovery program Automatically discovers AP devices to simplify configuration and management

(PCs with Windows-based operating systems only).

SNMP support Enables the AP to be centrally managed by popular standards-based

network management applications.

Auto configuration Copies settings from compatible APs on the WLAN, simplifying and

speeding setup.

SNMP support Enables the AP to be centrally managed by popular standards-based

network management applications such as SNMP v1 and v2c.

Syslog support Enables the AP to be centrally monitored by sending data to the network

Syslog server.

Web browser-based administration Familiar browser interface lets you configure and manage APs from

anywhere on the network.

Auto firmware update Automatically checks an FTP server for available firmware updates.

FEATURES AND BENEFITS (CONTINUED)

PoE Support

Choose from several power options to

match your installation needs. First, the

PoE access point can be powered with

the supplied PoE adapter.

You can also power the access point

using an 802.3af-compliant PoE switch.

The switch provides both data and power

through the Ethernet cable.
