Dual Gigabit with 24-Port 10/100 Switch
Installing the Switch
Fast Ethernet Considerations
If you will be using the Switch for Fast Ethernet (100Mbps) or Gigabit
(1000Mbps) applications, you must observe the following guidelines:
• The maximum UTP cabling length using Category 3 cable is 328 feet (100
meters).
• The maximum UTP cabling length using Category 5 cable is 328 feet (100
meters).
Full-Duplex Considerations
As previously mentioned, the Switch provides full-duplex support for its RJ-
45 ports. Full-duplex operation allows data to be sent and received simultane-
ously, doubling a port’s potential data throughput.
If you will be using the Switch in full-duplex mode, the maximum UTP cable
length using Category 5e (or better) cable is 328 feet (100meters).
Positioning the Switch
Before you choose a location for the Switch, observe the following guide-
lines:
• Keep cabling away from sources of electrical noise, power lines, and
fluorescent lighting fixtures.
• Position the Switch away from water and moisture sources.
• To ensure adequate air flow around the Switch, be sure to provide a
minimum of one inch (25mm) clearance.
• Do not stack free-standing Switches more than four units high.

The EtherFast

Dual Gigabit with 24-Port 10/100 Switch is equipped with
twenty-four 10/100 RJ-45 ports. These RJ-45 ports support network speeds of
either 10Mbps or 100Mbps, and can operate in half- and full-duplex modes.
Auto-sensing technology enables each port to automatically detect the speed
of the device connected to it (10Mbps or 100Mbps), and adjust its speed and
duplex accordingly. Each port also auto-senses the type of cable being used,
either straight-through or crossover.
To connect a device to a port, you will need to use a network cable. UTP
Category 3 cable is acceptable for 10BaseT networks, however, if you are
using 100BaseTX devices you will need to use UTP Category 5 (or better)
cable. The two Gigabit ports require UTP Category 5e cable (or better).

Dual Gigabit with 24-Port 10/100 Switch is equipped with
two Gigabit ports. These ports provide links to high-speed network segments
or individual workstations at speeds of up to 2000Mbps (Gigabit Ethernet).
The two Gigabit ports require UTP Category 5e cable (or better).

Dual Gigabit with 24-Port 10/100 Switch is equipped with a
serial port (located on the rear of the switch) that allows you to connect to a
computer (for configuration purposes) using the provided serial cable.
