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.
