3 C O M ® I N T E L L I J A C K ™ S W I T C H FA M I LY D ATA S H E E T, U.S.-S TA N D A R D M O D E L S 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 provides 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 costsavings 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 singleport midspan power source equipment (PSE) that inject Power over Ethernet into existing switched networks. To help preserve your telephony investments, an optional power-conversion module enables prestandard 3Com NBX® phones to support 802.3af-compliant inline power.
