3COM® INTELLIJACK® SWITCH FAMILY: U.S.–STANDARD

KEY BENEFITS

COST-SAVING INFRASTRUCTURE EXPANSION

With innovative 3Com IntelliJack switches, organizations can quadruple

the number of LAN ports in almost any location—incurring significantly

lower costs and experiencing less business disruption than if they were

to deploy conventional switches and install additional Ethernet cable.

ADAPTABLE DEVICE CONNECTIVITY

One 3Com IntelliJack switch provides four 10/100 Mbps switched ports.

The NJ220 and NJ100 models can be equipped with additional LAN

connections—optional adapter plates provide pass-through with up to

two ports for RJ-11 and/or RJ-45 connectors. The NJ240FX model turns

a single, two-fiber multimode cable into four 10/100 switched ports and

also provides a pass-through RJ-45 connector for voice or data.

INNOVATIVE IN-THE-WALL INSTALLATION

The compact, wall-mounted units reduce workspace clutter and protect

connections from tampering, damage and theft. The switches mount

without disturbing walls, making them particularly well suited for

older buildings and facilities where installing new wiring is difficult.

FLEXIBLE POWER OPTIONS

Power sources* for IntelliJack NJ220 and NJ100 switches include inline

IEEE 802.3af PoE, a local AC power adapter and power forwarding. The

NJ240FX model comes with its own internal AC power supply and also

supports power forwarding to a downstream device.

CONVERGED SECURE NETWORKING

IntelliJack switches support a number of advanced capabilities for

converged networks, including IEEE 802.1p and IP v4 traffic prioriti-

zation to ensure the proper quality of service (QoS) levels. To enhance

service and security, the IntelliJack NJ220 and NJ240FX can also label

voice traffic as high priority and route it through its own virtual LAN

(VLAN). Security features for the NJ220 and NJ240FX models include

VLANs, IEEE 802.1X network login, MAC filtering and port-based rate

limiting by speed and type, helping to prevent network abuse

and unauthorized access.

FULL COMPLEMENT OF MANAGEMENT CAPABILITIES

The enterprise-ready IntelliJack NJ220 and NJ240FX switches come

bundled with software utilities that help streamline administration

tasks. The switches can be discovered and controlled by most SNMP-

compliant management platforms, including 3Com Network Supervisor

and HP OpenView. 3Com Local Configuration Manager eases installation

and configures the switches to support central management, while

Central Configuration Manager provides remote monitoring for single

switches or groups of switches. In addition, a location-mapping feature

aids troubleshooting and IT asset inventories.

SEAMLESS INFRASTRUCTURE INTEGRATION

IntelliJack switches fully comply with Ethernet, Fast Ethernet, Voice

over IP (VoIP), PoE and relevant building and telecommunications

wiring specifications.
