3Com Network Jack NJ100
The NJ100 provides the same
connectivity options as the NJ220,
but without management support.
Optional pass-through ports and
Power over Ethernet forwarding let
you terminate additional voice, cable,
or network wiring in the same wall
outlet. The wall-mounted case pro-
vides durability and permanence for
high-traffic locations, such as printer
rooms or public kiosks.
3Com Network Jack NJ90
For networks that don’t require device
manageability or extra pass-through
ports, this unmanaged 10/100 Mbps
switch can deliver significant cost-
savings when compared to pulling and
activating Category 5e cabling for the
same number of LAN connections.
Power over Ethernet
In addition to the SuperStack endspan
switch, 3Com offers 24- and single-
port midspan power source
equipment (PSE) that inject Power
over Ethernet into existing switched
networks. To help preserve your tele-
phony investments, an optional
power-conversion module enables
prestandard 3Com NBX
®
phones to
support 802.3af-compliant inline
power.
