Chapter 3 Switch Installation (8-Port Switches) Installing the Switch For configuration instructions about using the CLI setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.” Rack-Mounting This section is specific to the Catalyst 2960 8-port switches. For information applicable to the other Catalyst 2960 switches, see Chapter 2, “Switch Installation (24- and 48-Port Switches).
Chapter 3 Switch Installation (8-Port Switches) Installing the Switch Mounting the Switch in a 19-Inch Rack After the brackets are attached to the switch, insert the switch into the 19-inch rack, and align the bracket in the rack. Use either the 10-32 pan-head screws or the 12-24 pan-slotted screws to secure the switch in the rack, as shown in Figure 3-9. Note We strongly recommend that you allow at least 1.75 inches (4 cm) of clearance above each switch in the rack.
Chapter 3 Switch Installation (8-Port Switches) Installing the Switch To mount the switch with brackets on a wall, follow these steps: Step 1 Attach a 19-inch bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side, as shown in Figure 3-10. Step 2 Mount the switch with the front panel facing down, as shown in Figure 3-10.
Chapter 3 Switch Installation (8-Port Switches) Where to Go Next Where to Go Next If the default configuration is satisfactory, the switch needs no further configuration. You can use any of these management options to change the default configuration: • Start the device manager, which is in the switch memory, to manage individual and standalone switches. The device manager is a web interface that offers quick configuration and monitoring.
CH A P T E R 4 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 1-12. 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 4 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 4 Troubleshooting Diagnosing Problems Ethernet and Fiber Cables Make sure that you have the correct cable type for the connection: • For Ethernet, use Category 3 copper cable for 10 Mb/s unshielded twisted pair (UTP) connections. Use either Category 5, Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mb/s connections. • For fiber-optic connectors, verify that you have the correct cable for the distance and port type.
Chapter 4 Troubleshooting Diagnosing Problems Use the show interfaces privileged EXEC command to verify the port or interface error-disabled, disabled, or shutdown status on both sides of the connection. If necessary, re-enable the port or the interface. Ping the End Device Verify the end device connection by first pinging it from the directly connected switch, and then work your way back port by port, interface by interface, trunk by trunk, until you find the source of the connectivity issue.
Chapter 4 Troubleshooting Clearing the Switch IP Address and Configuration To maximize switch performance and to ensure a link, follow one of these guidelines when you set or change the settings for duplex and speed: • Let both ports autonegotiate both speed and duplex. • Manually set the speed and duplex parameters for the ports on both ends of the connection. • If a remote device does not autonegotiate, configure the duplex settings on the two ports to match.
Chapter 4 Troubleshooting Locating the Switch Serial Number Locating the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the serial number of your switch. See Figure 4-1 through Figure 4-3 to locate the serial number on your switch. You can also use the show version command to get the serial number.
