Adaptable Device Connectivity
Each 3Com
®
IntelliJack
switch pro-
vides four 10/100 Mbps switched
LAN ports and an uplink. Choose the
managed NJ225 or unmanaged NJ105
models, each with an optional "pass
through" port giving an additional
LAN connection. Use the NJ225 FX
model when the uplink cable is fiber.
“In the Wall” Design
Compact wall-mounted unit reduces
workspace clutter and safeguards 
network connectivity from tampering,
damage, or theft.
Flexible Power
Power options include IEEE 802.3af
Power over Ethernet and power forward-
ing for reliable wiring-closet power, and
local AC power. Power is ordered
separately to lower overall installation
cost.
Designed for E.U. and U.K. Cut-Out Standards
The IntelliJack switch "international
standard" models are designed for fast,
safe and secure installation in wall 
cut-outs and raceways following E.U.
and U.K. cut-out standards. Switches
mount without disturbing wall spaces,
making them particularly suited for
older or hard-to-wire facilities. 
Converged, Secure Networks
Advanced capabilities—including
traffic prioritization, standards-based
VLANs, and a “location mapping” 
feature—optimize IntelliJack Switch
NJ225 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.

Innovative “in the Wall“ Solution: International-Standard
Transform a simple
LAN outlet into a
four-port, "in the
wall" Fast Ethernet
switch
3Com IntelliJack Switches are unique
"in the wall" devices that quickly and
easily convert a single LAN wall outlet
into four autonegotiating 10/100 Mbps
LAN ports. These international-
standard models were specially
designed for installation in cut-outs
and raceways that follow E.U. and U.K.
standards with 60 mm screw separa-
tions. 
Available are managed and unmanaged
models with a 10/100 uplink connection;
a 100BASE-FX uplink fiber version is
available as managed-only.
IntelliJack switches work in almost
any network environment—including
small-office or enterprise businesses,
government offices, dormitories, hos-
pitals, classrooms, public kiosks, and
conference rooms. Unlike freestanding
hubs or switches, IntelliJack switches
are not easily damaged or discon-
nected; nor are they susceptible to
theft.
