Safety and Regulatory Information. |
CAUTION Opening the switch or tampering with the warranty sticker can void your warranty.
Setting Up for |
To make full use of the features offered by your switch, and to change |
Management |
and monitor the way it works, you have to access the management |
|
software that resides on the switch. This is known as managing the |
|
switch. Managing the switch can help you to improve the efficiency of |
|
the switch and therefore the overall performance of your network. |
|
This section explains the initial set up of the switch and the different |
|
methods of accessing the management software to manage a switch. It |
|
covers the following topics: |
|
■ Methods of Managing a Switch |
|
■ Switch Setup Overview |
|
■ Using the Command Line Interface (CLI) |
|
■ Manually set the IP Address using the Console Port |
|
■ Viewing IP Information using the Console Port |
|
■ Setting Up Web Interface Management |
|
■ Setting Up Command Line Interface Management |
|
■ Setting Up SNMP Management V1 or V2 |
|
■ Default Users and Passwords |
Methods of
Managing a Switch
To manage your switch you can use one of the following methods:
■Web Interface Management
■Command Line Interface Management
■SNMP Management
You can use the Command Line Interface through the Console port for complete access to all operations of the switch including setting and viewing the IP address, configuring user accounts, upgrading switch firmware, and more. Refer to the 3Com CLI Reference Guide.
22 CHAPTER 1: GETTING STARTED
Web Interface Each switch has an internal set of web pages that allow you to manage Management the switch using a Web browser remotely over an IP network (see
Figure 2).
Figure 2 Web Interface Management over the Network
Refer to “Setting Up Web Interface Management” on page 30.
Command Line Each switch has a command line interface (CLI) that allows you to Interface manage the switch from a workstation, either locally via a console port
Management connection (see Figure 3), or remotely over the network (see Figure 4).

Switch Setup |
This section gives an overview of what you need to do to get your switch |
Overview |
set up and ready for management when it is in its default state. The |
|
whole setup process is summarized in Figure 6. Detailed procedural steps |
|
are contained in the sections that follow. In brief, you need to: |
|
■ Configure IP information manually for your switch or view the |
|
automatically configured IP information |
|
■ Prepare for your chosen method of management |

Switch Setup Overview |
25 |
By default the switch tries to configure its IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network.
Default IP Address If no DHCP server is detected, the switch will use its default IP information. The default IP address is 169.254.x.y, where x and y are the last two bytes of its MAC address.
Note: The switch’s default IP address is listed on a label located on the bottom and top of the switch.
If you use automatic IP configuration it is important that the IP address of the switch is static, otherwise the DHCP server can change the switch’s IP addresses and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the switch. Refer to the documentation that accompanies your DHCP server.
You should use the Automatic IP configuration method if:
■your network uses DHCP to allocate IP information, or
■flexibility is needed. If the switch is deployed onto a different subnet, it will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the switch.
If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the “Viewing IP Information using the Console Port” on page 28.
When you configure the IP information manually, the switch remembers the information that you enter until you change it again.
You should use the Manual IP configuration method if:
■You do not have a DHCP server on your network, or
■You want to remove the risk of the IP address ever changing, or
26CHAPTER 1: GETTING STARTED
■Your DHCP server does not allow you to allocate static IP addresses. (Static IP addresses are necessary to ensure that the switch is always allocated the same IP information.)
|
For most installations, 3Com recommends that you configure the switch |
|
IP information manually. This makes management simpler and more |
|
reliable as it is not dependent on a DHCP server, and eliminates the risk of |
|
the IP address changing. |
|
To manually enter IP information for your switch, work through the |
|
“Manually set the IP Address using the Console Port” on page 27. |
|
|
Using the |
You can access the switch through the Console port to manually set the |
Command Line |
IP address, or to view the IP address that was assigned automatically (for |
Interface (CLI) |
example, by a DHCP server). |
|
For more information about the CLI, refer to the 3Com CLI Reference |
|
Guide. |
Connecting to the |
This section describes how to connect to your switch through the |
Console Port |
Console port. |
■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 to DB-9) supplied with your switch.
You can find pin-out diagrams for the cable in Appendix C on page 235.
Using the Command Line Interface (CLI) 27
1Connect the workstation to the console port using the console cable as shown in Figure 7.
Figure 7 Connecting a Workstation to the switch using the Console Port
To connect the cable:
aAttach the cable’s RJ-45 connector to the Console port of the switch.
bAttach the other end of the cable to the workstation.
2Open your terminal emulation software and configure the COM port settings to which you have connected the cable. The settings must be set to match the default settings for the switch, which are:
■38,400 baud (bits per second)
■8 data bits
■no parity
■1 stop bit
■no hardware flow control
Refer to the documentation that accompanies the terminal emulation software for more information.
3Power up the switch. The Power on Self Test (POST) will be performed. The OfficeConnect Managed Fast Ethernet PoE Switch takes approximately two minutes to boot.
You are now ready to manually set up the switch with IP information using the command line interface.
■You need to have the following information:
■IP address
■subnet mask
■default gateway
28CHAPTER 1: GETTING STARTED
1Connect to the switch Console port as described in “Connecting to the Console Port” page 26.
2The command line interface login sequence begins as soon as the switch detects a connection to its console port. When the process completes, the Login prompt displays.
