This guide describes how to use Express Setup to initially configure your Catalyst switch. It also covers switch management options, basic rack-mounting, stacking, port and module connections, and troubleshooting.
For more installation and configuration information, see the Catalyst 3750-X and 3560-X documentation on Cisco.com. For system requirements, important notes, limitations, open and resolved bugs, and documentation updates, see the release notes on Cisco.com.
(Optional) RJ-45 console cable 2
(Optional) USB console cable 2
(Optional) StackWise cable (0.5-meter, 1-meter, or 3-meter) 2
(Optional) StackPower cable (0.305-meter or 1.5-meter) 2
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 access the switch through the IP address for further configuration.
- PC with Windows Vista, XP, or 2000
- Straight-through or crossover Category 5 Ethernet cable
Note Write down the static IP address. You will need this IP address in Step 13.
If the LEDs next to the Mode button blink when you press the button, release it. Blinking LEDs mean that the switch is already configured and cannot go into Express Setup mode. For more information, see the “Resetting the Switch to the Default Settings” section.
- Any 10/100/1000 Ethernet port on the switch front panel
- The RJ-45 management port on the switch rear panel
Note We recommend that you use the default VLAN value. During Express Setup, VLAN 1 is the only VLAN on the switch. 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 switch IP address.
- In the Subnet Mask field, click the drop-down arrow, and select a 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.
You can enter other administrative settings in the Optional Settings fields. For example, the optional administrative settings identify and synchronize the switch for enhanced management. NTP automatically synchronizes the switch clock with the network clock. You can manually set the system clock if the switch should have different settings.
- 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, re-enter the Telnet password.
- In the SNMP field, click Enable to enable Simple Network Management Protocol (SNMP). Enable SNMP only if you plan to manage switches by using CiscoWorks 2000 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 you cannot change it. When you set the SNMP write community, you can both access and change SNMP information.
- In the System Contact and System Location fields, enter a contact name and the wiring closet, floor, or building where the switch is located.
- (Optional) In the Enable IPv6 field, click Enable to enable IPv6 on the switch.
- The switch is configured and exits Express Setup mode.
- The browser displays a warning message and tries to connect with the earlier switch IP address. Typically, connectivity between the PC and the switch is lost because the configured switch IP address is in a different subnet from the IP address on the PC.
Disconnect the switch from the PC, and install the switch in your network. See the “Installing the Switch” section.
If you changed the static IP address on your PC in Step 2, change it to the previously configured static IP address.
See the “Managing the Switch” section for information about configuring and managing the switch.
2. Enter the switch IP address, username, and password assigned in Step 8 in the browser, and press Enter . The device manager page appears.
- Confirm that the port LED for the switch port connected to your network is green.
- Confirm that the PC or laptop that you are using has network connectivity by connecting it to a well-known web server in your network. If there is no network connection, troubleshoot the network settings on the PC or laptop.
- Make sure that the switch IP address in the browser is correct.
- If the switch IP address in the browser is correct, the switch interface LED is green, and the PC or laptop has network connectivity, continue troubleshooting by reconnecting the PC or laptop to the switch. Configure a static IP address on the PC or laptop that is in the same subnet as the switch IP address.
- When the LED on the switch port connected to the PC or laptop is green, re-enter the IP address of the switch in a browser to display the device manager. When the device manager appears, you can continue with the configuration.
The simplest way to manage the switch is by using the device manager in the switch memory. This is a web interface that offers quick configuration and monitoring. You can access it through a web browser.
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.

You can use SNMP management applications such as CiscoWorks Small Network Management Solution (SNMS) and HP OpenView to configure and manage the switch. You 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 Cisco Networking Services (CNS) agents in the switch software. You can use the Registrar to automate initial configurations and configuration updates.
See the “Accessing Help Online” section for supporting documentation.
This section covers basic 19-inch rack-mounting. The illustrations show the Catalyst 3750X-48P switch. You can install and connect other Catalyst 3750-X and 3560-X switches as shown. See the hardware installation guide on Cisco.com.
- Clearance to front so that the LEDs can be read.
- AC power cord reaches from the AC power outlet to the rear-panel connector.
- Switch is rack-mounted before you install a 1100-W power supply module.
- Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting. Make sure the cabling is safely away from other devices that might damage the cables. If needed, allow one RU space between devices to provide room for cabling.
- Airflow around the switch and through the vents is unrestricted.
- Temperature around the unit does not exceed 113°F (45°C). If the switch is in a closed or multirack assembly, the temperature might be higher than normal room temperature.
- Humidity around the switch does not exceed 85 percent.
- Altitude at the installation site is below 10,000 feet.
- For 10/100/1000 fixed ports, cables from the switch to connected devices are not longer than 328 feet (100 meters).
- Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing contaminant buildup inside the chassis, which can result in system malfunction. Install the switch in an environment as free as possible from dust and foreign conductive material (such as metal flakes from construction activities).
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). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings. Statement 17B
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.
Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:
This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006
Connect the cable to the StackWise port on the switch rear panel. Use the window in the StackWise cable to align the connector. Use a ratcheting torque screwdriver to tighten the retainer screws to 5-inch pound of torque. Connect the other end of the cable to the port of the other switch, and tighten the retainer screws to 5-inch pound of torque. Avoid overtightening the screws.
Caution Removing and installing the StackWise cable can shorten its life. Do not remove and insert the cable more often than is necessary.
Align the connector and connect the StackPower cable to the S-PWR port on the switch rear panel and finger-tighten the screw. Connect the other end of the cable to the port on the other switch and finger-tighten the screw. Avoid overtightening the screws.
Caution Removing and installing the StackPower cable can shorten its life. Do not remove and insert the cable more often than is necessary.
When you connect to servers, workstations, IP phones, wireless access points, and routers, use a straight-through, twisted four-pair, Category 5 cable in a 10/100/1000 port. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters. Connect the other cable end to an RJ-45 port on the other device.
Note The automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The switch detects the required cable type for copper Ethernet connections and configures the interfaces. You can use either a crossover or a straight-through cable for connections to a copper 10/100/1000 module port on the switch, regardless of the type of connected device.
Use only Cisco SFP modules with the switch. 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 SFP module documentation.
After you connect a device to the switch port, the port LED turns amber for about 30 seconds while the switch establishes a link. The LED turns green when the switch and the attached device have a link. If the LED is off, the device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the device.
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.
First look for a solution to your problem in the troubleshooting section of the hardware installation guide or the software configuration guide on Cisco.com. You can also access the Cisco Technical Support and Documentation website for a list of known hardware problems and extensive troubleshooting documentation.
