CH A P T E R 2 Switch Installation This chapter describes how to install and connect a Catalyst 3850 switch. It also includes planning and cabling considerations for stacking switches.
Chapter 2 Switch Installation Preparing for Installation Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage. Statement 48 Warning Ethernet cables must be shielded when used in a central office environment. Statement 171 Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted.
Chapter 2 Switch Installation Preparing for Installation Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: 10/100/1000 Ethernet.
Chapter 2 Switch Installation Planning a Switch Data Stack • For copper connections on Ethernet ports, cable lengths from the switch to connected devices can be up to 328 feet (100 meters). • For cable requirements for SFP+ module connections, see the “Cable and Adapter Specifications” section on page B-5. Each port must match the wave-length specifications on the other end of the cable, and the cable must not exceed the minimum cable length.
Chapter 2 Switch Installation Data Stack Cabling Configurations Switch Stacking and Power Stacking Guidelines For general concepts and management procedures for switch stacks, see the switch software configuration guide on Cisco.com. Before connecting the switches in a stack, keep in mind these stacking guidelines: • Size of the switch and any optional power-supply module. The 1100-W power-supply module is longer than the other modules.
Chapter 2 Switch Installation Data Stack Cabling Configurations Data Stacking up to Four Switches in a Side-by-Side Mounting 344183 Figure 2-2 Data Stack Bandwidth and Partitioning Examples This section provides examples of data stack bandwidth and possible data stack partitioning. Figure 2-3 shows a data stack of Catalyst 3850 switches that provides full bandwidth and redundant StackWise cable connections.
Chapter 2 Switch Installation Data Stack Cabling Configurations Figure 2-5 and Figure 2-6 show data stacks of Catalyst 3850 switches with failover conditions. In Figure 2-5, the StackWise cable is bad in link 2. Therefore, this stack provides only half bandwidth and does not have redundant connections. In Figure 2-6, link 2 is bad. Therefore, this stack partitions into two stacks, and the top and bottom switches become the active switch in the stack.
Chapter 2 Switch Installation Planning a StackPower Stack • If some switches in the stack are completely separated from the stack, a stack split can take occur. • A stack split can occur on a full ring stack if: – More than one running switch is removed without powering down. – More than one stack cable is removed without powering down. • A stack split can occur in a partial ring stack if: – A switch is removed without powering down. – A stack cable is removed without powering down.
Chapter 2 Switch Installation StackPower Cabling Configurations • Size of the switch and any optional power supply module. The 1100-W power-supply module is 1.5 inches (3.81 cm) longer than the other modules, and with the attached cable retention clip, it extends 3 inches (7.62 cm) from the switch chassis. Stacking switches with the same power-supply modules together makes it easier to cable the switches. For switch dimensions, see Appendix A, “Technical Specifications.” • Length of cable.
Chapter 2 Switch Installation StackPower Cabling Configurations Figure 2-8 shows a ring configuration using both of the supplied 0.3-meter StackPower cables and one 1.5-meter cable. In these examples, the switches are stacked in a vertical rack or on a table.
Chapter 2 Switch Installation Installing the Switch StackPower Partitioning Examples Figure 2-9 and Figure 2-10 show StackPower stacks of Catalyst 3850 switches with failover conditions. In Figure 2-9, the StackPower cable 2 is faulty. Therefore, this stack does not provide redundancy. Figure 2-9 Example of a StackPower Stack with a Failover Condition 1 3 344188 2 In Figure 2-10, StackPower port B on the center switch has failed and this stack partitions into two stacks.
Chapter 2 Switch Installation Installing the Switch Rack-Mounting To install the switch in a 19-inch rack, follow the instructions described in this section. 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.

CH A P T E R 6 Troubleshooting • Diagnosing Problems, page 6-1 • Resetting the Switch, page 6-5 • Finding the Switch Serial Number, page 6-6 • Replacing a Failed Data Stack Member, page 6-6 Diagnosing Problems The switch LEDs provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from the CLI, or an SNMP workstation.
Chapter 6 Troubleshooting Diagnosing Problems Switch Connections Bad or Damaged Cable Always examine the cable for marginal damage or failure. A cable might be just good enough to connect at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors. You can identify this situation because the port has many packet errors or the port constantly flaps (loses and regains link). • Exchange the copper or fiber-optic cable with a known good cable.
Chapter 6 Troubleshooting Diagnosing Problems 10/100/1000 Port Connections A port appears to malfunction: • Verify the status of all ports. See Table 1-5 on page 1-11 for descriptions of the LEDs and their meanings. • Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or shut down. Reenable the port if necessary. • Verify the cable type. See Appendix B, “Connector and Cable Specifications.
Chapter 6 Troubleshooting Diagnosing Problems Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher. • For long wave SFP+ modules, a mode conditioning patch might improve performance over maximum link distances with MMF connections. Interface Settings Verify that the port or interface is not disabled or powered off. If a port or interface is manually shut down on either side of the link, it does not come up until you reenable the interface.
Chapter 6 Troubleshooting Resetting the Switch Autonegotiation and Network Interface Cards Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch ports and interfaces autonegotiate. Laptops or other devices are commonly set to autonegotiate, yet sometimes issues occur. To troubleshoot autonegotiation problems, try manually setting both sides of the connection.
Chapter 6 Troubleshooting Finding the Switch Serial Number Finding the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the switch serial number. Figure 6-1 shows the serial number location. You can also use the show version privileged EXEC command to see the switch serial number.
