The 12-Port Gigabit Ethernet Switch’s Back Panel

FAN	Radiates the heat inside the system.
Buzzer	Warns you if the system overheats. To disable the
	warning system, use a pen point or similar object to
	push in the button and the buzzer will not sound if
	the system overheats.
Power	The Power port is where you will connect the
	included power cord.

Ports 1-12	These twelve LAN (Local Area Network) ports con-
	nect network devices, such as PCs, print servers,
	network attached storage, and remote hard drives at
	10/100/1000Mbps. Or, they can be used to expand
	your network by connecting to a 1000Mbps hub or
	switch. When connecting to a PC equipped with an
	Instant Gigabit Network Adapter, just plug one end
	of a Category 5e Ethernet network cable into the RJ-
	45 port on the Adapter and the other end into one of
	the ports on the Gigabit Ethernet Switch.

	ature is too high.
Power	Green. The Power LED lights up when the Switch is powered
	on.
1000	Green. The 1000 LED lights up when the port is operating at
	1000Mbps. If the LED is off, the port is operating at either
	100Mbps or 10Mbps, or it is not active.
100	Green. The 100 LED lights up when the port is operating at
	100Mbps. If this LED is off, the port is operating at either

	10Mbps. If this LED is off, the port is operating at either
	1000Mbps or 100Mbps, or it is not active.
FDX	Amber. If the FDX (Full Duplex/Collision) LED is lit up
	continuously, the connection made through the correspon-

	collisions are normal. If this LED is blinking often, there
	may be a problem with your connection.
