The ports have locator pins fitted and are designed for stan dard (pinless) connectors .
3 S ETTING U P FOR M ANAGEMENT Y our Switch can operate in its default state, that is, you can install it and it will work straight away (plug-and- play). However , to make full use of the features of fered by the Switch, and to change and monitor the way it works, you have to acce ss the management software that r esides on the Switch.
36 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Setting Up Overview This section gives an overview of what you need to do to get your Switch set up and ready for management wh en it is in its de fault state. The whole setup process is summarized in Figure 9.
Setting Up Overview 37 CAUTION: T o protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Swit ch. For more inform ation on defau lt users and changing default passwords, see “Def ault Users and Passwords” on page 55 .
38 C HAPTER 3: S ETTING U P FOR M ANAGEMENT This process is known as Auto-IP and is the same mechanism used by Wi ndows 98 and W indows 2000. IP a ddresses configured by Auto-IP are temporary as they cannot be routed but ar e useful for small networks which are not connected to other netw orks, or for initial configuration.
Manually Configuring IP Informatio n 39 Manually Configuring IP Information Y ou can manually configure the Switch IP information in the following ways: ■ Connecting to a front panel port — Connect a works tation using an Ether net cable to a front panel port of the Switch.
40 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Connecting the W orkstat ion to the Switch 1 Connect the workstation to a front panel port using an Ethernet cable as shown in Figure 10.
Manually Configuring IP Informatio n 41 If there is no response, wait for one minute then re-enter the default IP address. 3 At the login and password pr ompts, enter admin as your user name and press Return at the p assword pr ompt (default user n ame and password).
42 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Figure 11 Example top-level command line interface menu 4 At the Select menu option prompt you can either: ■ enter th e protocol ip basicConfig command. At the Enter configuration method prompt enter manual .
Manually Configuring IP Informatio n 43 Pre-r equisites ■ A workstation with terminal emulation soft ware installed, such as Microsoft Hyperterminal. This software allows you to communicate with the Switch via the console port directly , or through a modem.
44 C HAPTER 3: S ETTING U P FOR M ANAGEMENT 2 Open your terminal emulation software and configure the COM port settings to which you have connected the cable.
Manually Configuring IP Informatio n 45 Figure 13 Example top-level command line interface menu 3 At the Select menu option prompt you can either: ■ enter th e protocol ip basicConfig command. At the Enter configuration method prompt enter manual . The screen prompts you to enter IP information.
46 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Viewing Automatically Configured IP Information If you allow the Switch to automatica lly configure its own IP information you need to discover and view the IP information before you can begin to manage the Switch.
Viewing Automaticall y Configured IP Information 47 ■ A suitable cable: ■ A standard null modem cable — if you ar e connecting directly to the console port, or ■ A standard modem cable — if y ou are connecting to the console port using a modem.
48 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Viewing IP Information via the Console Port Y ou are now r eady to view the auto matically allocate d IP information using the command line interface. 1 Connect your Switch to the network using an Ether net cable.
