Key Benefits
Transform a simple
LAN outlet into a
four-port, “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
®
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.
Converged, Secure Networks
Advanced capabilities including
traffic prioritization, port-based
VLANs, and a “location mapping”
feature that optimize 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 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
legs and vanish.”
One NJ90 Network Jack expands a
single LAN link into four autonegoti-
ating 10/100 Mbps LAN ports. The
NJ100 and NJ200 provide added
flexibility with optional pass-through
connectivity and Power over Ethernet
forwarding capabilities. The intelligent
NJ200 comes with advanced switching
and management capabilities, making
it particularly suited for converged
voice and data environments.
3Com Network Jacks power sources,
which are required and sold sepa-
rately, include inline Power over
Ethernet and local AC adapters. For
an integrated endspan solution, the
3Com SuperStack
®
3 Switch 4400
PWR combines standard data
switching and power injection in a
single network appliance.
