Chapter 3 Switch Installation (8-Port Switches) Installing the Switch Magnet 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).” Step 1 Place one side of the magnet against the bottom of the switch, as shown in Figure 3-7.
Chapter 3 Switch Installation (8-Port Switches) Installing the Switch 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).” Installing the Catalyst 2960 8-port switches in a 19-inch rack requires an optional bracket kit that is not included with the switch. You can order a kit containing the 19-inch rack-mounting brackets and hardware from Cisco.
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 Warning Read the wall-mounting instructions carefully before beginning installation. Failure to use the correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage to the system. Statement 378 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.
Chapter 3 Switch Installation (8-Port Switches) Where to Go Next For configuration instructions about using the CLI setup program, go to Appendix C, “Configuring the Switch with the CLI-Based Setup Program.” 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.
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 1-14. 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 Port and Interface Settings An obvious but sometimes overlooked cause of port connectivity failure is a disabled port. Verify that the port or interface is not disabled or for some reason powered off. If a port or interface is manually shut down on one or the other side of the link, the link does not come up until you re-enable the port.
Chapter 4 Troubleshooting Clearing the Switch IP Address and Configuration These circumstances can result in a mismatch: • A manually set speed or duplex parameter is different from the manually set speed or duplex parameter on the connected port. • A port is set to autonegotiate, and the connected port is set to full duplex with no autonegotiation.
Chapter 4 Troubleshooting Locating the Switch Serial Number The switch now behaves like an unconfigured switch. You can configure the switch by using Express Setup as described in the switch getting started guide that is included with the switch. You can also configure the switch by using the CLI setup procedure described in Appendix C, “Configuring the Switch with the CLI-Based Setup Program.
