The 3Com NJ105 is part of the IntelliJack family of products that
provides connectivity at the edge of the network infrastructure.
The NJ105 IntelliJack is a 4-port, un-managed Fast Ethernet
switch that fits into most standard data port openings.
The NJ105 IntelliJack quadruples port connections where a single
port (and cable) already exists in the wall. Expanding port
connections with the 3Com IntelliJack is a less expensive and less
disruptive alternative to running additional cabling. Also, the
3Com IntelliJack is installed in the wall, making it more secure
and out of the way than deploying a remote desktop switch.
The NJ105 IntelliJack allows up to four networking devices, such
as computers, printers, Voice over IP (VoIP) telephones, and
scanners, to be connected to the network via its own Ethernet
port. A pass-through port is provided that allows an additional
device to be connected to a separate network segment through
the same IntelliJack.
All ports feature 10/100 Mbps auto-negotiation, which
configures the NJ105 IntelliJack for 10 Mbps or 100 Mbps
connections automatically.
