Manually Configuring IP Information

Connecting to the

Console Port

You can manually configure the switch IP information by:

■Connecting a workstation to the switch’s console port using a console cable. You can then manually enter the IP information using the command line interface (CLI). This is the only way to assign an IP address to a device that does not have an IP address already, or that has an unknown IP address. You can also use this method to change switch’s IP information.

■Connecting a workstation to one of the port’s on the switch’s front panel using an Ethernet cable. You can then manually enter the IP information using the web interface or the command line interface. This is only applicable if the device already has an IP address and you know that address.

To set up your switch manually you can make a connection to the console port, (this example describes a local connection to the console port, rather than one using a modem). You can do this while the switch is offline (before you connect the switch to a network) or while the switch is online (connected to a network).

Prerequisites

■A workstation with terminal emulation software installed, such as Microsoft Hyperterminal. This software allows you to communicate with the switch using the console port directly.

■Documentation supplied with the terminal emulation software.

■The console cable (RJ-45) supplied with your switch.

You can find pin-out diagrams for the cable in “Pin-outs” on page 57.

■IP information, including:

■IP address

■subnet mask

■default gateway

■management VLAN ID, normally set to the default value (1)

Connecting the Workstation to the Switch

To connec the workstation to the switch, perform the following steps:

1Connect the workstation to the console port using the console cable as shown in Figure 31.

Connection

To connect the cable:

aAttach the RJ-45 connector on the cable to the console port of the switch.
