3 Running Express Setup When you first set up the switch, you should use Express Setup to enter the initial IP information. Doing 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. You need this equipment to set up the switch: • A PC with Windows 2000 or XP installed. • A web browser (Internet Explorer 5.5, 6.0, Netscape 7.1 or later) with JavaScript enabled.
Step 5 Press and hold the Mode button for 3 seconds. When all of the LEDs above the Mode button turn green, release the Mode button.
Step 11 The Express Setup Basic Settings page appears. If it does not appear, see the “In Case of Difficulty” section on page 22. Step 12 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. The VLAN ID range is 1 to 1001. • In the IP Address field, enter the IP address of the switch.
Step 15 (Optional) You can select the Advanced Settings tab on the Express Setup window and enter the advanced settings now or enter them later by using the device manager interface. Step 16 (Optional) Enter this information in the Advanced Setting fields: • 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.
Step 18 To complete Express Setup, click Submit in the Network Settings or the Advanced Settings screen to save your settings. 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 tries 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.
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.
Using the switch Ethernet management port: Follow these steps: 1. Connect a Category 5 Ethernet cable to the PC Ethernet port. Connect the other end of the cable to the Ethernet management port on the switch rear panel. 2. Start a Telnet session on the PC. 3. Enter the switch IP address that you assigned by using Express Setup. 4. Use the CLI to enter commands to configure the switch. See the software configuration guide and the command reference for more information.
5 Planning Switch Stacks Before connecting the switches in a stack, keep in mind these stacking guidelines: • Size of the switch and any optional power supply module. The 1150-W power supply module is longer than the other modules. Stacking switches with the same power supply modules together makes it easier to cable the switches. • Length of cable. Depending on the configurations that you have, you might need different sized cables. If you do not specify the length of the StackWise cable, the 0.
Stack Cabling Configurations These illustrations show the recommended switch stack configurations with redundant StackWise cabling connections for optimized stack bandwidth. For more configuration examples, see the hardware installation guide on Cisco.com. Vertical Stacking 158112 In this example, the stack uses the 0.5-meter StackWise cable to make redundant connections. 158113 In this example, the stacks use both the 0.5- and the 3-meter StackWise cables to make redundant connections.
Side-By-Side Stacking 86825 In this example, eight switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables. 90532 In this example, nine switches are stacked side-by-side with redundant connections by using 0.5- and 3-meter StackWise cables.
6 Rack-Mounting This section covers basic 19-inch rack-mounting and switch port connections. As an example, all the illustrations show the Catalyst 3750E-48 PoE switch. You can install and connect other Catalyst 3750-E switches as shown in these illustrations. For additional installation and cabling information, see the hardware installation guide on Cisco.com. Equipment That You Supply You need a Phillips screwdriver to rack-mount the switch.
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 3750-E and Catalyst 3560-E Switch document that shipped with the switch and is also available on Cisco.com. Warning To prevent the switch from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 113°F (45°C).
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 Caution To comply with the Telcordia GR-1089 Network Equipment Building Systems (NEBS) standard for electromagnetic compatibility and safety, connect the Ethernet cables only to intrabuilding or nonexposed wiring or cabling.
Attaching the Brackets Use four number-8 Phillips flat-head screws to attach the long side of each bracket to the switch in one of three mounting positions.
Rack-Mount the Switch Use the four number-12 Phillips machine screws to attach the brackets to the rack. Use the black Phillips machine screw to attach the cable guide to the left or right bracket.
Connect the StackWise Cables Use the window in the StackWise cable to align the connector correctly. Insert the cable into the StackWise port on the back of the switch. Using a ratcheting torque screwdriver, tighten the retainer screws to 5 lbf-in. (80 ozf-in.). Insert the other end of the cable into the connector of the other switch, and tighten the retainer screws to 5 lbf-in. (80 ozf-in.). Avoid overtightening the screws. Always use a Cisco-approved StackWise cable to connect the switches.
7 Connect to the Switch Ports This section describes how to connect to the fixed switch ports and to the 10-Gigabit Ethernet module slots. Connect to 10/100/1000 Ports The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.
Install and Connect to Devices in the 10-Gigabit Ethernet Slots The switch 10-Gigabit Ethernet module slots are used for connections to other switches and routers. The module slots operate in full-duplex mode and use the hot-swappable Cisco X2 transceiver modules and the Cisco TwinGig Converter Module. The X2 transceiver modules have SC connectors to connect to multimode fiber (MMF) and single-mode fiber (SMF) cables.
8 In Case of Difficulty If you experience difficulty, help is available in this section and also 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.
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 incorrect IP address. • You want to clear all configuration from the switch and assign a new IP address.
