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 simultaneously, 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.

Linksys EtherFast®II Series

The 10/100 Managed 24-Port GigaSwitch is equipped with twenty-four autosensing RJ-45 ports. These RJ-45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half- and full-duplex modes. Autosensing 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 modules. 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 information 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 connect to a computer (for configuration purposes) using the provided serial cable.

Pre-Installation Considerations

The Console Port

10/100 Managed 24-Port GigaSwitch

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

If you need to reset the GigaSwitch, depress the RESET button (located on the rear of the switch) for approximately one or two seconds.

Port 24 on the EtherFast II 10/100 Managed 24-Port GigaSwitch can act as an uplink port, allowing you to uplink to other switches or hubs using a standard Ethernet connection.

To uplink the switch, connect one end of a Category 5 (or better) network cable into Port 24, then connect the other end of the cable into the desired network device’s uplink port. To enable uplinking capability, depress the MDI/MDIX button on the front of the switch.

Use the following instructions to install the Gigabit Expansion Modules:

Before you begin power off the GigaSwitch by disconnecting all cables from the GigaSwitch.

1. Place the GigaSwitch right side up, with the rear panel facing you.

2. Use a screwdriver to remove the desired Expansion Module cover plate

(labeled “Slot 1” and “Slot 2”). Set the screws aside for step 4.

3. Insert the Gigabit Expansion Module (must be purchased seperately) into

the selected Gigabit Expansion Port, ensuring that it is seated firmly in place.

4. Secure the module in place using the screws and a screwdriver.

The Gigabit Expansion Module installation is complete.

You can now re-connect the cables to the back of the GigaSwitch.

Linksys EtherFast®II Series

The 10/100 Managed 24-Port GigaSwitch can be used as a free-standing unit, or installed in any standard 19-inch rack.

Use the following instructions to rack-mount the GigaSwitch:

Before you begin, disconnect all cables from the GigaSwitch.

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

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

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 GigaSwitch.

5. Insert the GigaSwitch 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 back of the GigaSwitch.

Remote Console Management

You can manage the GigaSwitch remotely by having a remote host establish a Telnet connection to the switch via an Ethernet or modem link.

To use this management method:

• The host must run a SLIP protocol if a modem is used

• The GigaSwitch must have an IP address

The Remote Console Management interface is identical in appearance and functionality to the Local Console Management interface. If you are using Microsoft’s Telnet, the terminal setting should be set to VT100/ANSI.

SNMP Management

You can manage the GigaSwitch across a LAN using an SNMP Network Management Station with a graphical user interface. This management method allows you to monitor statistical counters and set switch parameters from the remote Network Management Station.

To use this management method:

• The network must use the IP protocol

• The GigaSwitch must be configured on the network with a proper IP address

Assigning an IP Address to the GigaSwitch

To manage the GigaSwitch remotely through the console port or with an SNMP Management Station, you must assign an IP address to the GigaSwitch. To assign an IP address to the GigaSwitch, refer to page 44 in the Configuring the GigaSwitch section.

Logging On to the GigaSwitch

When you log on to the GigaSwitch for the first time, a sign-in string appears and you are prompted for a console login name and password. The factory default login name is set as “admin” and the password is “123456”. If you desire, you can change this password after you log on.

Linksys EtherFast®II Series

Switch Management

The Linksys EtherFast II 10/100 24-Port Managed GigaSwitch offers an easyto-use, menu-driven console interface. Using this interface, you can perform various switch configuration and management activities, including:

• Configuring system and por t parameters

• Assigning an IP address

• Configuring routing proper ties

• Configuring ARP

• Configuring DHCP

• Setting VLAN policy

• Setting packet filtration

• Configuring STP and SNMP parameters

• Upgrading software

There are four methods of managing the GigaSwitch:

• Local Console Management using the serial port

• Remote Console Management using a network or dial-up connection

• Using an SNMP Management Station

• Web-Browser

Local Console Management

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

Before you log on to the GigaSwitch, make sure that the switch’s serial por t settings are as follows:

BAUD RATE: 115200 FLOW: None PARITY: None STOP BITS: 1 DATA BITS: 8

EMULATION: ANSI CURSOR EMULATION: VT100
