DATA SHEET

Key Benefits

Transform a simple

LAN outlet into a

four-port, intelligent,

“in the wall” Fast

Ethernet switch

Cost-Saving Infrastructure Expansion

Quadruple your LAN ports with

significantly lower costs and fewer

disruptions than pulling extra

Ethernet cables.

Adaptable Device Connectivity

One 3Com

IntelliJack

™

Switch

provides four 10/100 Mbps switched

LAN ports and optional ports for

telephony or additional LAN

connections.

“In the Wall” Design

Compact wall-mounted unit reduces

workspace clutter and safeguards

network connectivity from tampering,

damage, or theft.

Flexible Power

Options include IEEE 802.3af Power

over Ethernet, locally available AC

power, and power forwarding.

Converged, Secure Networks

Advanced capabilities including

traffic prioritization, industry-

standard VLANs, and a “location

mapping” feature that optimizes

network jack connections for voice,

video, and data.

Seamless Integration

Standards compliance includes

Ethernet, Fast Ethernet, Voice over IP

(VoIP), Power over Ethernet, and

building and telecommunications

wiring specifications.

Drop-In Installation

Switches mount without disturbing

wall spaces, making them particularly

suited for older or hard-to-wire

facilities.

3Com IntelliJack switches are unique

"in the wall" devices that quickly con-

vert single port LAN wall outlets into

four switched ports. They work in

almost any network environment—

including enterprise businesses,

government offices, dormitories, hos-

pitals, classrooms, laboratories, public

kiosks, conference rooms, and shared

office spaces. Unlike freestanding

hubs or switches, these intelligent

network jacks are not easily damaged

or disconnected, and they are affixed

to the wall for added physical security.

The new IntelliJack Switch NJ220

comes with advanced switching and

management features, making it par-

ticularly suited for converged voice

and data environments, with the

added flexibility of optional pass-

through connectivity and Power over

Ethernet forwarding capabilities. The

Network Jack NJ100 is similar to the

NJ220 but without remote manage-

ment controls. The Network Jack

NJ90 is 3Com's most economical solu-

tion for expanding a single LAN link

into four autonegotiating 10/100 Mbps

LAN ports.

3Com compatible power sources,

which are required and sold separately,

include inline Power over Ethernet

and local AC adapters. For an inte-

grated endspan solution, the 3Com

SuperStack

3 Switch 4400 PWR

combines standard data switching

and power injection in a single

network appliance.
