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.

IntelliJack Powering and Power over Ethernet

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

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

support.

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

connection common in Germany; this

is supported "out of the box" and

requires nothing additional to use.
