3Com NJ100 Network Jack
The NJ100 provides the same connec-
tivity options as the NJ200, but
without management support.
Optional pass-through ports and
Power over Ethernet forwarding let
you to terminate additional voice,
cable, or network wiring in the same
wall outlet. The wall-mounted case
provides durability and permanence
for high-traffic locations, such as
printer rooms or public kiosks.
3Com NJ90 Network Jack
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. For large installations, the
cost-saving Power over Ethernet
bundle includes a P802.3af-compati-
ble 24-port midspan PSE, 20 network
jacks, and accessories. To help
preserve your telephony investments,
an optional power-conversion module
enables prestandard 3Com NBX
®
phones to support P802.3af-compliant
inline power.
