four-port, "in the

wall" Fast Ethernet

switch

DATA SHEET

3Com

Network Jacks

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

Network Jack 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 tamper-

ing, damage, or theft.

Flexible Power

Options include IEEE P802.3af draft

Power over Ethernet, locally available

AC power, and power forwarding.

3Com Network Jacks work in almost

any network environment—including

small-office or enterprise businesses,

government offices, dormitories, hos-

pitals, K-12 classrooms, universities,

laboratories, public kiosks, conference

rooms, and shared office spaces.

Unlike freestanding hubs or switches,

network jacks are not easily damaged

or disconnected; nor will they "grow
