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

II Series
The 10/100 Managed 24-Port GigaSwitch is equipped with twenty-four auto-
sensing 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.
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. For more information on twisted-pair cabling, refer to the Twisted-Pair
Cabling section on page 80.
The 10/100 Managed 24-Port GigaSwitch is equipped with two gigabit
expansion ports, providing for the installation of one or two expansion mod-
ules. These ports provide links to high-speed network segments or individual
workstations at speeds of up to 1000Mbps (Gigabit Ethernet).
To establish a Gigabit Ethernet connection, you will need to install a SX or
TX Gigabit expansion module and use fiber optic cabling. for more informa-
tion on fiber optic cabling, refer to the Fiber Optic Cabling section on page
79.
The 10/100 Managed 24-Port GigaSwitch is equipped with a serial port
labeled CONSOLE (located on the rear of the switch) that allows you to con-
nect to a computer (for configuration purposes) using the provided serial cable.
