User's Guide

Connecting the Terminal to the Switch

To monitor and configure the switch via serial console, use the console port on the rear of the switch to connect it to a VT100 terminal or to a computer running VT100 terminal emulation software. The console port is implemented as a data terminal equipment (DTE) connector.

The following is required to use the console port:

• VT100-compatible terminal or a desktop or a portable system with a serial port, running VT100 terminal emulation software.

• A serial cable (provided) with a RJ-45 connector for the console port and DB9 connector for the terminal.

Perform the following tasks to connect a terminal to the switch console port:

Connect the DB9 connector on the serial cable to the terminal running VT100 terminal emulation software.

Configure the terminal emulation software as follows:

Select the appropriate serial port (serial port 1 or serial port 2) to connect to the console.

Set the data rate to 9600 baud.

Set the data format to 8 data bits, 1 stop bit, and no parity.

Set the flow control to none.

Set the terminal emulation mode to

Select Terminal keys for Function, Arrow, and Ctrl keys. Make sure that the setting is for Terminal keys (not Microsoft

VT100

located on your

NOTE: When using HyperTerminal with Microsoft Windows 2000, make sure that you have Windows

2000 Service Pack 2 or later installed. With Windows 2000 Service Pack 2, the arrow keys function properly in HyperTerminal's VT100 emulation. Go to www.microsoft.com for more information on Windows 2000 service packs.

Connect the RJ-45 connector on the cable directly to the switch console port. The

PowerConnect 8024 and 8024F console port is located on the rear panel, above the RJ-45 out-of-band port, as shown in Figure 3.

Getting Started Guide 9

Figure 3. Connecting to the Console Port

The RJ-45 port below the Console port is for out-of-band management.

www.dell.com | support.dell.com

Booting the Switch

Make sure that the switch console port is connected to a VT100 terminal or VT100 terminal emulator via the RJ-45 to DB9 female cable.

Locate two AC power receptacles.

Deactivate the AC power receptacle.

Connect both of the switch power supplies to the AC receptacles.

Activate the AC power receptacles.

When the power is turned on with the local terminal already connected, the switch goes through a power-on self-test (POST). POST runs every time the switch is initialized and checks hardware components to determine if the switch is fully operational before completely booting. If POST detects a critical problem, the program flow stops. If POST passes successfully, valid firmware is loaded into RAM. POST messages are displayed on the terminal and indicate test success or failure. The boot process runs for approximately 60 seconds.

Console Port

Initial Configuration

NOTE: The initial simple configuration procedure is based on the following assumptions:

• The PowerConnect switch was never configured before and is in the same state as when you received it.

• The PowerConnect switch booted successfully.

• The console connection was established and the Dell Easy Setup Wizard prompt appears on

the screen of a VT100 terminal or terminal equivalent.

The initial switch configuration is performed through the console port. After the initial configuration, you can manage the switch either from the already-connected console port or remotely through an interface defined during the initial configuration.

NOTE: The switch is not configured with a default user name and password.

NOTE: All of the settings below are necessary to allow the remote management of the switch through

Telnet (Telnet client) or HTTP (Web browser).

10 Getting Started Guide

Before setting up the initial configuration of the switch, obtain the following information from your network administrator:

• The IP address to be assigned to the management VLAN.

• The IP subnet mask for the network.

• The IP address of the management VLAN default gateway.

Management Interface and Out-of-Band Interface

The front panel of the PowerConnect 8024 and 8024F switches contains multiple 10-Gigabit Ethernet ports for data traffic. Additionally, you can use any port on the front panel as the in-band management interface. The rear panel contains a Gigabit Ethernet port for out-of-band (OOB) management. The OOB port is located below the console port.

The Dell Easy Setup Wizard configures network information for the in-band management interface. To use the OOB interface for management, use the Command Line Interface (CLI) to configure network information. You can assign a static IP address and subnet mask or enable DHCP and allow a DHCP server to assign the information automatically.

NOTE: DHCP can be enabled on either the management interface or the OOB interface, but not both.

DHCP is enabled by default on the management interface. To use DHCP on the OOB interface, you must first disable it on the management interface and then enable it on the OOB interface.

See the PowerConnect 8024 and 8024F CLI Reference Guide for information about the commands to use to configure the OOB interface.

Initial Configuration Procedure

You can perform the initial configuration using the Dell Easy Setup Wizard, or by using the Command Line Interface (CLI). The Setup Wizard automatically starts when the switch configuration file is empty. You can exit the wizard at any point by entering [ctrl+z], but all configuration settings specified will be discarded (the switch will use the default values).

NOTE: If you do not run the Easy Setup Wizard or do not respond to the initial Easy Setup Wizard prompt

within 60 seconds, the switch enters CLI mode. If the switch is connected to your network through the management interface when you power it on for the first time, it attempts to acquire an IP address from a DHCP server. If no DHCP server responds to the request within 50 seconds, the switch uses 192.168.2.1 as the default IP address on the management VLAN. To view the management interface IP address, enter

enable command to enter Privileged EXEC mode, and then enter show ip interface

the

management

. There is no default IP address for the OOB interface.

Getting Started Guide 11

For more information on CLI initial configuration see the shows how to use the Setup Wizard for initial switch configuration. The wizard sets up the following configuration on the switch:

• Establishes the initial privileged user account with a valid password. The wizard configures one privileged user account during the setup.

• Enables CLI login and HTTP access to use the local authentication setting only.

• Sets up the IP address for the management VLAN.

• Sets up the SNMP community string to be used by the SNMP manager at a given IP address. You may choose to skip this step if SNMP management is not used for this switch.

• Allows you to specify the management server IP or permit management access from all IP

www.dell.com | support.dell.com

addresses.

• Configures the default gateway IP address.

Example Session

This section describes an Easy Setup Wizard session. The following values are used by the example session:

• The SNMP community string to be used is

• The network management system IP address is

• The user name is

• The IP address for the management VLAN is

• The default gateway is

The setup wizard configures the initial values as defined above. After you complete the wizard, the switch is configured as follows:

• SNMPv1/2c is enabled and the community string is set up as defined above. SNMPv3 is disabled by default.

• The admin user account is set up as defined.

• A network management system is configured. From this management station, you can access the SNMP, HTTP, and CLI interfaces. You may also choose to allow all IP addresses to access these management interfaces by choosing the (0.0.0.0) IP address.

• An IP address is configured for the default management VLAN (1).

• A default gateway address is configured.

Applying configuration, please wait ...

Welcome to Dell Easy Setup Wizard

The Setup Wizard guides you through the initial switch configuration, and gets you up and running as quickly as possible. You can skip the setup wizard, and enter CLI mode to manually configure the switch. You must respond to the next question to run the setup wizard within 60 seconds, otherwise the system will continue with normal operation using the default system configuration.Note: You can exit the setup wizard at any point by entering [ctrl+z].

Would you like to run the setup wizard (you must answer this question within 60 seconds)? [Y/N] y

Step 1:

The system is not setup for SNMP management by default. To manage the switch using SNMP (required for Dell Network Manager) you can

. Set up the initial SNMP version 2 account now.

. Return later and setup other SNMP accounts. (For more

information on setting up an SNMP version 1 or 3 account, see the user documentation).

Would you like to setup the SNMP management interface now? [Y/N] y

To setup the SNMP management account you must specify the management system IP address and the "community string" or password that the particular management system uses to access the switch. The wizard automatically assigns the highest access level [Privilege Level 15] to this account. You can use Dell Network Manager or other management interfaces to change this setting and to add additional management systems later. For more information on adding management systems, see the User’s Guide.

Getting Started Guide 13

To add a management station:

Please enter the SNMP community string to be used [public]:public

NOTE: If it is configured, the default access level is set to the highest available access for the SNMP

management interface. Initially only SNMPv1/2c will be activated. SNMPv3 is disabled until you return to configure security access for SNMPv3 (e.g. engine ID, view, etc.).

Please enter the IP address of the Management System (A.B.C.D) or wildcard (0.0.0.0) to manage from any Management Station {0.0.0.0}: 192.168.2.100

Step 2:

Now we need to setup your initial privilege (Level 15) user

www.dell.com | support.dell.com

account. This account is used to login to the CLI and Web interface. You may setup other accounts and change privilege levels later. For more information on setting up user accounts and changing privilege levels, see the user documentation.

To setup a user account:

Please enter the user name. [admin]:admin Please enter the user password:******** Please reenter the user password:********

Step 3:

Next, an IP address is setup. The IP address is defined on the default VLAN (VLAN #1), of which all ports are members. This is the IP address you use to access the CLI, Web interface, or SNMP interface for the switch. Optionally you may request that the system automatically retrieve an IP address from the network via DHCP (this requires that you have a DHCP server running on the network).

To setup an IP address:

Please enter the IP address of the device (A.B.C.D) or enter "DHCP" (without the quotes) to automatically request an IP address from the network DHCP server. [192.168.2.1]:192.168.2.1

Please enter the IP subnet mask (A.B.C.D or /nn). [255.255.255.0]:255.255.255.0

14 Getting Started Guide

Step 4:

Finally, setup the default gateway. Please enter the IP address of the gateway from which this network is reachable. [0.0.0.0]:

This is the configuration information that has been collected:

SNMP Interface = "public"@192.168.2.100 User Account setup = admin Password = ******** Management IP address = 192.168.2.1 255.255.255.0 Default Gateway = 0.0.0.0 Operation Mode = Normal

Step 5:

If the information is correct, please select (Y) to save the configuration, and copy to the start-up configuration file. If the information is incorrect, select (N) to discard configuration and restart the wizard: [Y/N] y

Thank you for using Dell Easy Set up Wizard. You will now enter CLI mode.

Advanced Configuration

This section provides summary information about such common tasks as:

• Retrieving an IP Address From a DHCP Server

• Security Management and Password Configuration

NOTE: For detailed information on all the CLI commands available for the 8024 and 8024F M6348

switches, see the CLI Reference Guide.

Retrieving an IP Address From a DHCP Server

When using the DHCP protocol to retrieve an IP address, the switch acts as a DHCP client.

To retrieve an IP address from a DHCP server, perform the following steps:

Select and connect any port to a DHCP server or to a subnet that has a DHCP server on it, in order to retrieve the IP address.

NOTE: You do not need to delete the switch configuration to retrieve an IP address for the D HCP server.

Enter the following commands to use the selected port for receiving the IP address.

console#config

console(config)#ip address dhcp

The interface receives the IP address automatically.

Getting Started Guide 15

To verify the IP address, enter the show ip interface command at the system prompt as shown in the following example.

console#show ip interface

Security Management and Password Configuration

System security is handled through the AAA (Authentication, Authorization, and Accounting) mechanism that manages user access rights, privileges, and management methods. AAA uses both local and remote user databases. Data encryption is handled through the SSH mechanism.

The system is delivered with no default password configured; all passwords are user-defined. If a user-defined password is lost, a password recovery procedure can be invoked from the Boot menu. The procedure is applicable for the local terminal only and allows a one-time access to the switch from the local terminal with no password entered.
