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.
Methods of Managing a Switch 49 The initial set up of your Switch is now complete and the Switch is r eady for you to set up your chosen management method.
50 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Command Line Interface Management using SSH The Switch 4400 supports Secure Shell version 2 (SSHv2), allowing secure access to the Command Line Interface of the Switch.
Setting Up Command Line Interface Management 51 CLI Management via the Console Port T o manage a Switch using the co mmand line interface via the local console port connection: 1 Ensure you have conne cted your work station to the console port correctly as described in “Connecting to the Console Port” on page 42.
52 C HAPTER 3: S ETTING U P FOR M ANAGEMENT Setting Up Command Line Interface Management using SSH This section describes how you ca n set up Command Line Interface management using SSH over a netwo rk.
Setting Up Web Interface Management 53 For further information on generati ng a host key on your switch and transferring keys to the Swit ch us ing TF TP ser ver p lease refer to Chapter 11 of the “SuperStack 3 Switch Implementation Guide”.
54 C HAPTER 3: S ETTING U P FOR M ANAGEMENT ■ V ariable Width Font - Size 10.0 ■ Fixed W idth Font - Size 12.0 This ensur es that the text spac ing is corr ect. Finally in the Advanced category ensure that Enable Java Script and Enable style sheets are checked.
Default Users and Passwords 55 automatically loads the correct MIBs and necessar y files onto your workstation. Pre-r equisites ■ Documentation supplied with the SNMP netwo rk management application software.

4 P RO B L E M S OLVING This chapter helps you to diagnose and solve problems you may have with the operation of your Switch. There is also an explanation of IP addressing.
58 C HAPTER 4: P ROBLEM S OLV ING Solving Problems Indicated by LEDs If the LEDs on the Switch indicate a problem, r efer to the list of su ggested solutions below . The Power LED does not light Check that the power cable is firmly connected to the Switch and to the supply outlet.
Solving Hardware Problems 59 ■ Auto-negotiation settings are the same at both ends. Auto-negotiation problems will occur with 10BASE-T or 100BASE-T where auto-negotiation is disabled a nd incorr ect.
60 C HAPTER 4: P ROBLEM S OLV ING Switch. The monitoring system polls the fan status at periodic intervals while the unit is powered up. If one fan has failed in the Switch, a warning message wi ll be.
Solving Hardware Problems 61 Unit fails, no SNMP fan failur e message is received 1 Power cycle the unit. T o do this, remove and r econnect the AC mains supply .
62 C HAPTER 4: P ROBLEM S OLV ING Solving Communication Problems If you experience communication problems with the Switch, ensur e that: ■ The Switch IP address and Manageme nt VLAN ID has been configured as described in Chapter 3.
Solving Software Upgrade Problems 63 If your IP network is inter nal to your organization only , that is, you do not access the Internet, you ma y use any arbitrary IP a ddress as long a s it is not being used by another device on your network. 3Com suggests you use addresses in the range 192.
