IntelliJack switches come with no
means to directly power the unit;
switch power sources are required
and sold separately.
Power over Ethernet (PoE) support
with the IntelliJack switches helps
lower deployment costs. The NJ105
and NJ225 models can utilize stan-
dards-based IEEE 802.3af PoE power
obtained from their 10/100 uplink
connection. If a source for PoE power
is needed, 3Com has an integrated
endspan solution, the 3Com
SuperStack
®
3 Switch 4400 PWR,
combining an enterprise-class switch
with power injection in a single device;
also available are mid-span PoE
options to add power to an existing
Ethernet wiring infrastructure.
When Power over Ethernet is not
used to power the IntelliJack, a local
AC power adapter can be purchased.
The NJ225 FX model can also be
powered by a "phoenix-style"
connection common in Germany; this
is supported "out of the box" and
requires nothing additional to use.

IntelliJack Models Give
Deployment Choice
3Com IntelliJack Switch NJ225
The NJ225 model is for enterprise
accounts looking for a managed
solution to quadruple ports in an
infrastructure with copper 10/100
connections. This "in the wall"
managed switch comes bundled with
software utilities that help streamline
administration tasks and boost network
security. Advanced switching and
management features make it ideal for
connecting networked telephony.
Enterprise ready, this model can be
discovered and controlled by most
SNMP-compliant management
platforms — including 3Com Network
Supervisor and HP OpenView.
3Com IntelliJack Switch NJ225 FX
The NJ225 FX model shares the
management capabilities of the NJ225
model. It is designed for environments
where the uplink connection will be
100BASE-FX fiber.
3Com IntelliJack Switch NJ105
The NJ105 provides the same 10/100
copper-based connectivity options
as the NJ225, but without Network
Login security and management
support.
