Getting to Know the Switch

Power (Green) The LED will illuminate when the switch is

powered on.

PER PORT

Link/Act (Green/Amber) The LED will illuminate green when the

port makes a connection at 100Mbps, and flash green when there is activity on the port at 100Mbps. The LED will illuminate amber when the port makes a connection at 10Mbps, and flash amber when there is activity on the port at 10Mbps.

FD/Col (Amber) The LED will illuminate amber when the port is

operating in full-duplex mode, and flicker amber when collisions are being encountered.

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 RJ45 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 (100meters).

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 (25mm) clearance.

• Do not stack free-standing Switches more than four units high.

Instant Gigabit®Series

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 por t 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).

The EtherFast®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).

The EtherFast®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.

Pre-Installation Considerations

The Console Port

Switch Management

The Linksys EtherFast®Dual Gigabit with 24-Port 10/100 Switch offers an easy-to-use, menu-driven console interface. Using this interface, you can perform various switch configuration and management activities, including:

• Configuring system and por t parameters

• Configuring routing proper ties

• Setting VLAN policy

• Configuring Port Trunking

Local Console Management

You can manage the Switch locally by connecting the switch to a PC or workstation with terminal emulation software using the serial port.

The serial port settings need to be conf igured before connecting to the Switch. In order to change the settings of your port, run the Hyperterminal program. This program comes packaged with Windows, but it may not be installed on your computer. It should be located as is shown below (varies according to operating system). If it is not, consult your Windows documentation for instructions on installing Hyperterminal.

1. Click the Start button. Select Accessories and then Communications.

Hyperterminal should be one of the options listed in this menu. Select Hyperterminal.

Overview

Instant Gigabit®Series

The EtherFast®Dual Gigabit with 24-Port 10/100 Switch can be used as a free-standing unit, or installed in any standard 19-inch rack.

Use the following instructions to rack-mount the Switch:

Before you begin, disconnect all cables from the Switch.

1. Place the Switch right side up, with the front panel facing you.

2. Position a mounting bracket over the screw holes on one side of the Switch.

3. Secure the mounting bracket by inserting three screws into the screw holes. Use a screwdriver to tighten the screws, ensuring that they are fastened f irmly in place.

4. Repeat steps 2 and 3 to install the other mounting bracket on the opposite side of the Switch.

5. Insert the Switch into the 19-inch rack and secure it with suitable screws (not provided). Ensure that the ventilation holes are not obstructed.

The rack-mount installation is complete.

You can now re-connect the cables to the Switch.

To power on the Switch, simply connect the AC power cord to the back of the Switch, then plug the power cord into an electrical outlet. The Switch will boot up within approximately 30 seconds.

Any of the 26 ports on the EtherFast®Dual Gigabit with 24-Port 10/100 Switch can act as an uplink port, allowing you to uplink to other switches or hubs using a standard Ethernet connection. UTP Category 5e (or better) cable is recommended when using the Gigabit ports.

To uplink the switch, connect one end of a network cable into the Switch, then connect the other end of the cable into the desired network device’s uplink port.
