Chapter 2 Switch Installation Preparing for Installation Warnings These warnings are translated into several languages in the Regulatory Compliance and Safety Information for the Catalyst 3750 Switch document that ships with the switch. 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.
Chapter 2 Switch Installation Preparing for Installation 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.
Chapter 2 Switch Installation Preparing for Installation Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046 Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of: 45°C Statement 1047 Warning This warning symbol means danger. You are in a situation that could cause bodily injury.
Chapter 2 Switch Installation Preparing for Installation Installation Guidelines When you decide where to place the switch, be sure to observe these requirements: Note • For copper Ethernet ports, including 10/100 ports, 10/100/1000 ports, and 1000BASE-T SFP module ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters).
Chapter 2 Switch Installation Preparing for Installation Verifying Package Contents Note Carefully remove the contents from the shipping container, and check each item for damage. If any item is missing or damaged, contact your Cisco representative or reseller for support. Return all packing material to the shipping container, and save it.
Chapter 2 Switch Installation Planning the Stack Powering On the Switch and Running POST If your configuration has an RPS, connect the switch and the RPS to the same AC power source. See the “Power Connectors” section on page 1-25, and see the Cisco RPS documentation for more information. Note Always set the RPS in standby mode when you are connecting devices to it and in active mode during normal operation.
Chapter 2 Switch Installation Planning the Stack Planning Considerations Before connecting the Catalyst 3750 switches in a stack, observe these planning considerations: • Size of the switch. For switch dimensions, see Appendix A, “Technical Specifications.” Some switches are deeper than the other switches. Stacking switches of the same size together makes it easier to cable the switches. • Length of cable. Depending on the configurations that you have, you might need cables of different sizes.
Chapter 2 Switch Installation Planning the Stack A Example of a Stack with Full Bandwidth Connections B C 86821 Figure 2-1 Figure 2-2 shows an example of a stack of Catalyst 3750 switches with incomplete StackWise cabling connections. This stack provides only half bandwidth and does not have redundant connections. Figure 2-2 Example of a Stack with Half Bandwidth Connections 86823 A B Figure 2-3 and Figure 2-4 show examples of stacks of Catalyst 3750 switches with failover conditions.
Chapter 2 Switch Installation Planning the Stack Recommended Cabling Configurations This section describes the recommended cabling configurations for stacking the switches. Stacking Switches in Vertical Racks or on a Table Figure 2-5 is an example of a recommended configuration using the supplied 0.5-meter StackWise cable. In this example, the switches are stacked in a vertical rack or on a table. This configuration provides redundant connections.
Chapter 2 Switch Installation Installing the Switch Side-by-Side Mounting in a Rack or on a Wall Figure 2-7 and Figure 2-8 are examples of recommended configurations where the switches are rack- or wall-mounted side-by-side. Use the 1-meter and 3-meter StackWise cables to connect the switches. These configuration provide redundant connections.

CH A P T E R 3 Troubleshooting The LEDs on the front panel provide troubleshooting information about the switch. They show failures in the power-on self-test (POST), port-connectivity problems, and overall switch performance. For a full description of the switch LEDs, see the “LEDs” section on page 1-13. You can also get statistics from the browser interface, from the command-line interface (CLI), or from a Simple Network Management Protocol (SNMP) workstation.
Chapter 3 Troubleshooting Diagnosing Problems Verify Switch POST Results As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the switch functions properly. It might take several minutes for the switch to complete POST. When the switch begins POST, the system LED slowly blinks green. When POST completes, the system LED blinks amber. If POST fails, the system LED remains amber. If POST completes successfully, the system LED rapidly blinks green.
Chapter 3 Troubleshooting Diagnosing Problems • For copper connections, determine if a crossover cable was used when a straight-through cable was required or the reverse. Enable auto-MDIX on the switch, or replace the cable. Link Status Verify that both sides have link. A single broken wire or one shutdown port can cause one side to show link, but the other side does not have link. A link LED does not guarantee that the cable is fully functional.
Chapter 3 Troubleshooting Diagnosing Problems • Bad or incorrect XENPAK module. Replace the suspect module with a known good module. Verify that the platform supports the module. See the Table B-2 on page B-4 for a list of supported XENPAK modules. • Use the show interfaces privileged EXEC command to check the port or module error-disabled, disabled, or shutdown status. Re-enable the port if necessary. • Make sure that all you have properly cleaned and securely connected all fiber-optic connections.
Chapter 3 Troubleshooting Diagnosing Problems Monitor Switch Performance Review this section when you troubleshoot switch performance problems. Speed, Duplex, and Autonegotiation If the port statistics show a large number of alignment errors, frame check sequence (FCS), or late-collisions errors, a speed or duplex mismatch might be the problem.
Chapter 3 Troubleshooting Clearing the Switch IP Address and Configuration Clearing the Switch IP Address and Configuration If you have configured a new switch with an incorrect IP address, or if all of the switch LEDs start blinking when you try to enter Express Setup mode, you can clear the IP address that is configured on the switch. Caution This procedure clears the IP address and all configuration information that is stored on the switch.
Chapter 3 Troubleshooting Finding the Switch Serial Number Step 4 Make the same Ethernet and Gigabit Ethernet connections on the replacement switch (as were on the failed switch). Step 5 Power on the replacement switch. Note If you add a replacement switch that has a later Cisco IOS release to the running stack, the replacement switch automatically downgrades to the release that the stack is running. The replacement switch, rather than the existing switches, reboots.

A P P E N D I X D Configuring the Switch with the CLI-Based Setup Program This appendix provides a CLI-based setup procedure for a standalone switch or a switch stack. Before connecting the switch to a power source, review the safety warnings in Chapter 2, “Switch Installation.” Note For detailed installation procedures on rack-mounting your switch, stacking your switches, or connecting to small form-factor pluggable (SFP) or XENPAK modules, see Chapter 2, “Switch Installation.
Appendix D Configuring the Switch with the CLI-Based Setup Program Accessing the CLI Accessing the CLI For an unconfigured switch, you can access the CLI through Express Setup or through the console port. Accessing the CLI Through Express Setup Note Express Setup is supported on switches running Cisco IOS Release 12.1(14)EA1 or later. If you are installing a new switch, see the Cisco IOS release label on the rear panel of the switch to determine the release.

Appendix D Configuring the Switch with the CLI-Based Setup Program Stacking the Switches (Optional) Stacking the Switches (Optional) You can stack up to nine switches by using the StackWise cables and ports to connect the switches (see Figure D-2). Read the “Planning the Stack” section on page 2-7 before you stack your switches. Figure D-2 Stacking the Switches CONSOLE RATIN 100-20 G 0V ~ 1.6A-0 >9A, 50-60 DC INPUT S POWE FOR REMO R SUPP TE SPECIFIED LY +12v IN MANUAL @8.
Appendix D Configuring the Switch with the CLI-Based Setup Program Connecting to the Console Port Connecting to the Console Port You can use the console port to perform the initial configuration. To connect the switch console port to a PC, use the supplied RJ-45-to-DB-9 adapter cable. Note If you have stacked your switches, connect to the console port of one of the switches in the stack. The initial configuration for the entire stack can be performed on any switch in the stack.
Appendix D Configuring the Switch with the CLI-Based Setup Program Starting the Terminal Emulation Software Starting the Terminal Emulation Software Before you power on the switch, start the terminal emulation session so that you can see the output display from the power-on self-test (POST). The terminal-emulation software—frequently a PC application such as Hyperterminal or ProcommPlus—makes communication between the switch and your PC or terminal possible.
Appendix D Configuring the Switch with the CLI-Based Setup Program Entering the Initial Configuration Information When POST completes successfully, the System LED remains green. The RPS LED remains green for some time and then returns to its operating status. The other LEDs turn off and return to their operating status. Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST. After you have powered all the switches in the stack, a switch is elected as the stack master.
Appendix D Configuring the Switch with the CLI-Based Setup Program Entering the Initial Configuration Information Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system. Would you like to enter basic management setup? [yes/no]: yes Step 2 Enter a host name for the switch, and press Return. On a command switch, the host name is limited to 28 characters; on a member switch to 31 characters.
Appendix D Configuring the Switch with the CLI-Based Setup Program Entering the Initial Configuration Information You have now completed the initial configuration of the switch and the switch displays its initial configuration.
