Innovative "in the Wall" Solution: U.S.-Standard
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.
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
Switch Family
™
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.
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.
