Chapter 3: Installing the Switch
Fast Ethernet and Gigabit Considerations
If you will be using the Switch for Fast Ethernet (100Mbps) or Gigabit
(1000Mbps) applications, you must observe this guideline:
The maximum UTP cabling length using Category 5 cable is 328 feet (100m).
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 simultaneously, 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 (100 m).
Positioning the Switch
Before you choose a location for the Switch, observe the following guidelines:
• 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 (25 mm) clearance.
• Do not stack free-standing Switches more than four units high.

Pre-Installation Considerations
The Switch is equipped with four 10/100/1000 RJ-45 ports, shown in Figure 2-
2. These RJ-45 ports support network speeds of 10/100 Mbps half-duplex and
20/200 Mbps full duplex Ethernet and Fast Ethernet speeds as well as up to
2000 Mbps Gigabit speed. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it, and adjust its speed and
duplex accordingly.
T o connect a de vice to a
port, you will need to
use a network cable. If
you are using
100BaseTX devices
you will need to use
UTP Category 5 (or
better) cable. Gigabit
devices require UTP
Category 5e cable (or
better).
The Switch is equipped with four Gigabit-module ports. These ports allow you
to add four high-speed ports, transmitting at speeds of up to 1000Mbps
(Gigabit Ethernet).
The Switch is equipped with a RS-232 serial port (located on the rear of the
Switch, as shown in Figure 2-3) that allows you to connect to a computer (for
configuration pur poses) using the provided serial cable.

program can be accessed by a console interface, a Web browser, a telnet connection, or SNMP/RMON. Using this configuration program, you can perform
various switch configuration and management activities, including:
• Enable/disable any port
• Set the communication mode for any port
• Configure SNMP parameters
• Add ports to network VLANs
• Create and manage VLAN Configurations
Local Console Management
You can manage the Switch locally using HyperTerminal; simply connect the
Switch to a PC or workstation through the serial port.
The serial port settings need to be configured before connecting to the Switch.
In order to change the settings of your port, run the HyperTerminal program.

Mirror Port Configuration
The Mirror Port Conf iguration screen, shown in Figure 6-21, allows you to
mirror traffic from any source port to a target port for real-time analysis.
You can then attach a logic analyzer or RMON probe to the target port and
study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port traff ic, the target port must be included in the
same VLAN as the source port.
•Port Mirroring - Enables or disables the mirror function.
• Mirroring Mode - Allows you to set the port to RX_MODE for receive or
TX_Mode for transmit.
•Mirror Port (Tx/Rx) - The port whose transmitted or received traffic
will be mirrored.
•Monitor Port - The port that will duplicate the transmitted or received
traffic appearing on the mirrored por t.
