Switch Family: U.S.–Standard

OVERVIEW

3Com

IntelliJack

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.
