Shipping Box Contents
3 Running Express Setup
When you first set up the switch, you should use Express Setup to enter the initial IP information. This enables the switch to connect to local routers and the Internet. You can then access the switch through the IP address for further configuration.
To run Express Setup:
Verify that no devices are connected to the switch, because during Express Setup, the switch acts as a DHCP server. If your PC has a static IP address, before you begin you should change your PC settings to temporarily use DHCP.
Connect the AC power cord to the switch and to a grounded AC outlet. The power-on self-test (POST) begins. During POST, the LEDs blink while a series of tests verify that the switch functions properly.
Wait for the switch to complete POST. It might take several minutes for the switch to complete POST.
Verify that POST has completed by confirming that the SYST LED rapidly blinks green. If the switch fails POST, the SYST LED turns amber.
POST errors are usually fatal. Call Cisco Systems immediately if your switch fails POST.
Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button.
If the LEDs above the Mode button begin to blink after you press the button, release it. Blinking LEDs mean that the switch has already been configured and cannot go into Express Setup mode. For more information, see the "Resetting the Switch" section.
Verify that the switch is in Express Setup mode by confirming that all LEDs above the Mode button are green. (The RPS LED remains off on some switch models.)
Connect a straight-through Category 5 Ethernet cable (not provided) to any 10/100/1000 Ethernet port on the switch front panel and to the Ethernet port on the PC.
Verify that the LEDs on both Ethernet ports are green.
Wait 30 seconds.
Launch a web browser on your PC. Enter the IP address 10.0.0.1 in the web browser, and press Enter.
The Express Setup page appears. If it does not appear, see the "In Case of Difficulty" section for help.
Enter this information in the Network Settings fields:
•In the Management Interface (VLAN ID) field, the default is 1. Enter a new VLAN ID only if you want to change the management interface through which you manage the switch and to which you assign IP information. The VLAN ID range is 1 to 1001.
•In the IP Address field, enter the IP address of the switch. In the IP Subnet Mask field, click the drop-down arrow, and select an IP Subnet Mask.
•In the Default Gateway field, enter the IP address for the default gateway (router).
•Enter your password in the Switch Password field. The password can be from 1 to 25 alphanumeric characters, can start with a number, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the Confirm Switch Password field, enter your password again.
(Optional) You can enter the Optional Settings information now or enter it later by using the device manager interface:
•In the Host Name field, enter a name for the switch. The host name is limited to 31 characters; embedded spaces are not allowed.
•In the System Contact field, enter the name of the person responsible for the switch. In the System Location field, enter the wiring closet, floor, or building where the switch is located.
•In the Telnet Access field, click Enable if you are going to use Telnet to manage the switch by using the command-line interface (CLI). If you enable Telnet access, you must enter a Telnet password.
•In the Telnet Password field, enter a password. The Telnet password can be from 1 to 25 alphanumeric characters, is case sensitive, allows embedded spaces, but does not allow spaces at the beginning or end. In the Confirm Telnet Password field, enter the Telnet password again.
•In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP). Enable SNMP only if you plan to manage switches by using CiscoWorks2000 or another SNMP-based network-management system.
If you enable SNMP, you must enter a community string in the SNMP Read Community field, the SNMP Write Community field, or both. SNMP community strings authenticate access to MIB objects. Embedded spaces are not allowed in SNMP community strings. When you set the SNMP read community, you can access SNMP information, but cannot modify it. When you set the SNMP write community, you can access and modify SNMP information.
Click Submit to save your settings, or click Cancel to clear your settings.
When you click Submit, the switch is configured and exits Express Setup mode. The PC displays a warning message and then attempts to connect with the new switch IP address. If you configured the switch with an IP address that is in a different subnet from the PC, connectivity between the PC and the switch is lost.
Disconnect the switch from the PC, and install the switch in your production network. See the "Managing the Switch" section for information about configuring and managing the switch.
If you need to rerun Express Setup, see the "Resetting the Switch" section.
Refreshing the PC IP Address
After you complete Express Setup, you should refresh the PC IP address.
For a dynamically assigned IP address, disconnect the PC from the switch, and reconnect it to the network. The network DHCP server will assign a new IP address to the PC.
For a statically assigned IP address, change it to the previously configured IP address.
4 Managing the Switch
After completing Express Setup and installing the switch in your network, use the device manager or other management options described in this section for further configuration.
Using the Device Manager
The simplest way to manage the switch is by using the device manager that is in the switch memory. This is an easy-to-use web interface that offers quick configuration and monitoring. You can access the device manager from anywhere in your network through a web browser.
Follow these steps:
1. Launch a web browser on your PC or workstation.
2. Enter the switch IP address in the web browser, and press Enter. The device manager page appears.
3. Use the device manager to perform basic switch configuration and monitoring. Refer to the device manager online help for more information.
4. For more advanced configuration, download and run the Cisco Network Assistant described in the next section.
Downloading Cisco Network Assistant
Cisco Network Assistant is a software program that you download from Cisco.com and run on your PC. It offers advanced options for configuring and monitoring multiple devices, including switches, switch clusters, switch stacks, routers, and access points. Network Assistant is free—there is no charge to download, install, or use it.
Follow these steps:
1. Go to this Web address: http://www.cisco.com/go/NetworkAssistant.
You must be a registered Cisco.com user, but you need no other access privileges.
2. Find the Network Assistant installer.
3. Download the Network Assistant installer, and run it. (You can run it directly from the Web if your browser offers this choice.)
4. When you run the installer, follow the displayed instructions. In the final panel, click Finish to complete the Network Assistant installation.
Refer to the Network Assistant online help and the getting started guide for more information.
You can enter Cisco IOS commands and parameters through the CLI. Access the CLI either by connecting your PC directly to the switch console port or through a Telnet session from a remote PC or workstation.
Follow these steps:
1. Connect the supplied RJ-45-to DB-9 adapter cable to the standard 9-pin serial port on the PC. Connect the other end of the cable to the console port on the switch.
2. Start a terminal-emulation program on the PC.
3. Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control.
4. Use the CLI to enter commands to configure the switch. See the software configuration guide and the command reference for more information.
Other Management Options
You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) and HP OpenView to configure and manage the switch. You also can manage it from an SNMP-compatible workstation that is running platforms such as HP OpenView or SunNet Manager.
The Cisco IE2100 Series Configuration Registrar is a network management device that works with embedded CNS agents in the switch software. You can use IE2100 to automate initial configurations and configuration updates on the switch.
See the "Accessing Help Online" section for a list of supporting documentation.
This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst 2970G-24TS switch. You can install and connect the Catalyst 2970G-24T switch as shown in these illustrations. For alternate mounting procedures, such as installing the switch in a 24-inch rack or on a wall, and for additional cabling information, see the Catalyst 2970 Switch Hardware Installation Guide on Cisco.com.
Equipment That You Supply
You need to supply a number-2 Phillips screwdriver to rack-mount the switch.
Before You Begin
When determining where to install the switch, verify that these guidelines are met:
Installation Warning Statements
This section includes the basic installation warning statements. Translations of these warning statements appear in the Regulatory Compliance and Safety Information for the Catalyst 2970 Switch document that shipped with the switch.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 148
Warning Installation of the equipment must comply with local and national electrical codes. Statement 1074
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Statement 39
Warning If a redundant power system (RPS) is not connected to the switch, install an RPS connector cover on the back of the switch. Statement 265
Warning Class 1 laser product. Statement 1008
Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: 10/100/1000 Ethernet. Statement 1044
Attaching the Brackets
Use four Phillips flat-head screws to attach the long side of the brackets to Catalyst 2970 switches in one of three mounting positions.
Rack-Mount the Switch
Use the black Phillips machine screw to attach the cable guide to the left or right bracket. Use the four number-12 Phillips machine screws to attach the brackets to the rack.
Connect to the Switch Ports
This section describes how to connect to the fixed switch ports and to the SFP module ports.
Connect to the 10/100/1000 Ports
Follow these steps:
When you connect to servers, workstations, IP phones, wireless access points, and routers, insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/100/1000 port. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.
Insert the other cable end into an RJ-45 connector on the other device.
Note The automatic medium-dependent interface crossover (Auto-MDIX) feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or later. When the Auto-MDIX feature is enabled, the switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100/1000 or 1000BASE-T SFP module port on the switch, regardless of the type of device on the other end of the connection.
Install the SFP Modules and Connect to the Ports
Follow these steps:
Grasp the module on the sides, and insert it into the switch slot until you feel the connector snap into place.
Insert an appropriate cable into the module port. Insert the other cable end into the other device.
For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on installing, removing, and connecting to SFP modules, see the documentation that came with the SFP module.
Caution Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.
Verify Port Connectivity
After you connect to the switch port, the port LED turns amber while the switch establishes a link. This process takes about 30 seconds, and then the LED turns green when the switch and the target device have an established link. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See the "In Case of Difficulty" section for information about online assistance.
6 In Case of Difficulty
If you experience difficulty, help is available here and on Cisco.com. This section includes Express Setup troubleshooting, how to reset the switch, how to access help online, and where to find more information.
Troubleshooting Express Setup
If Express Setup does not run, or if the Express Setup page does not appear in your browser:
•Did you verify that POST successfully ran before starting Express Setup?
If not, make sure that only the SYST and STAT LEDs are green before pressing the Mode button to enter the Express Setup mode.
•Did you press the Mode button while the switch was still running POST?
If yes, wait until POST completes. Power cycle the switch. Wait until POST completes. Confirm that the SYST and STAT LEDs are green. Press the Mode button to enter Express Setup mode.
•Did you try to continue without confirming that the switch was in Express Setup mode?
Verify that all LEDs above the Mode button are green. (The RPS LED is off.) If necessary, press the Mode button to enter Express Setup mode.
•Does your PC have a static IP address?
If yes, before connecting to the switch, change your PC settings to temporarily use DHCP.
•Did you connect a crossover cable instead of a straight-through Ethernet cable between a switch port and the Ethernet port of the PC?
If yes, connect a straight-through cable to an Ethernet port on the switch and the PC. Wait 30 seconds before entering 10.0.0.1 in the browser.
•Did you connect the Ethernet cable to the console port instead of to a 10/100/1000 Ethernet port on the switch?
If yes, disconnect from the console port. Connect to an Ethernet port on the switch and the PC. Wait 30 seconds before entering 10.0.0.1 in the browser.
•Did you wait 30 seconds after connecting the switch and the PC before entering the IP address in your browser?
If not, wait 30 seconds, re-enter 10.0.0.1 in the browser, and press Enter.
•Did you enter the wrong address in the browser, or is there an error message?
If yes, re-enter 10.0.0.1 in the browser, and press Enter.
Resetting the Switch
This section describes how to reset the switch by rerunning Express Setup. These are reasons why you might want to reset the switch:
•You installed the switch in your network and cannot connect to it because you assigned the wrong IP address.
•You want to clear all configuration from the switch and assign a new IP address.
•You are trying to enter Express Setup mode, and the switch LEDs start blinking when you press the Mode button (which means that the switch is already configured with IP information).
Caution Resetting the switch deletes the configuration and reboots the switch.
To reset the switch:
•Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch reboots.
The switch now behaves like an unconfigured switch. You can enter the switch IP information by using Express Setup as described in the "Running Express Setup" section.
