The 3Com NJ200 Network Jack is a 4-port, managed Ethernet switch that fits into
any standard electrical wall outlet or data port opening. It brings switching
capabilities to any single port on an Ethernet network by allowing you to connect
up to four networking devices, such as computer, printers, and Voice Over IP
(VoIP) telephones to the network via one Ethernet port. You can use optional
connectors to connect one or two additional devices to separate network
segments through the same Network Jack. All ports feature 10/100 Mbps
auto-negotiation.
Power to the Network Jack is provided through one of the following methods:
• Over the network via an integrated switch that supports Power Over Ethernet.
• Over the network via an optional single-port or multi-port Ethernet power
supply.
• Locally via an optional local power supply.
NOTE: Power Over Ethernet, also known as in-line power, is a method to
provide power to equipment over an Ethernet cable, allowing a device to
receive both data and power from the same network cable. The NJ200 is ideally
powered by a switch that is IEEE 802.3af-compatible or has a Capacitive Power
Discover Process (24V or 48V). The NJ200 can also be powered by some
switches which are not 802.3af-compatible. Consult the 3Com web site for
more information.
You can manage the NJ200 Network Jack using the included Central
Configuration Manager. You can also use a supported SNMP management
console as you would with any managed device on your network, but greater
management and control is available through the Configuration Manager
software. Management features include:
• Device discovery
• Port status (state, duplex, speed)
• Statistics
• Port control (port state, flow control, AutoMDI(X), multicast limit)
• QoS/Priority
• Port-based VLAN
• VLAN tag add/remove
• Firmware upgrade
