Appendix A: Detail Description of NJ95

The NJ95 is a 4-port, un-managed Fast Ethernet switch that fits into most standard data port openings. The NJ95 allows up to four networking devices, such as computers, printers, Voice over IP (VoIP) telephones, and scanners, to be connected to the network via one Ethernet port. An optional connector is available that allows an additional device to be connected to a separate network segment through the same NJ95.

The NJ95 needs no software to operate and requires no configuration. All ports feature 10/100 Mbps auto-negotiation, which configures the NJ95 for 10 Mbps or 100 Mbps connections automatically.

Power to the NJ95 can be provided in one of the following ways:

■Power over Ethernet using an Integrated Switch: Over the network via an integrated switch that supports IEEE 802.3af-compatible Power Over Ethernet (also known as In- line power, is a feature that provides power through an Ethernet cable, allowing a device to receive both data and power from the same network cable). See “Using an Integrated Switch with Power over Ethernet” on page 24.

■Power over Ethernet using a Midspan solution: Over the network via an optional Multi-port or Single-port Ethernet power supply. See “Using a Multi-port Ethernet Power Setting up the Power Supply” on page 25 or “Using a Single-port Ethernet Power Setting up the Power Supply” on page 27.
