OVERVIEW

switches quickly convert a single-port LAN wall
outlet into four switched Fast Ethernet ports. These intelligent, in-the-
wall “network jacks” deliver simple, economical connectivity to users
in hard-to-wire older buildings, crowded office spaces, public areas 
and virtually any other networked environment. Unlike conventional
switches, 3Com IntelliJack devices take up no horizontal space and are
difficult to accidentally disconnect or damage. Each switch delivers
traffic prioritization for converged applications. 
The 3Com IntelliJack Switch Family (U.S.-standard) offers a choice of
three models:
>
IntelliJack Switch NJ220—provides an array of advanced management,
switching and security features for copper networks; flexible power
options include Power over Ethernet (PoE), local AC power and power
forwarding; optional pass-through ports add one or two LAN links.
>
IntelliJack Switch NJ240FX—delivers advanced management,
switching and security for fiber LANs and comes with a copper
pass-through port; an internal AC power supply with power 
forwarding is included.
>
IntelliJack Switch NJ100—provides the same features as the NJ220
model, but without the management, switching and security
enhancements.
