C H A P T E R 2 Switch Installation Read these topics and perform the procedures in this order: • Preparing, page 2-1 • Planning a Switch Stack, page 2-6 • Installing the Switch, page 2-9 • Connecting to the Stack Ports, page 2-16 • Installing SFP Modules, page 2-17 • 10/100/1000 PoE Port Connections, page 2-19 • Where to Go Next, page 2-20 For initial switch setup, how to assign the switch IP address, and for powering information, see the switch getting started guide on Cisco.com.
Chapter 2 Switch Installation Preparing Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43 Warning Do not stack the chassis on any other equipment. If the chassis falls, it can cause severe bodily injury and equipment damage.
Chapter 2 Switch Installation Preparing Warning Class 1 laser product. Statement 1008 Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017 Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019 Warning This equipment must be grounded.
Chapter 2 Switch Installation Preparing Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard.
Chapter 2 Switch Installation Preparing Installation Guidelines Before installing the switch, verify that these guidelines are met: • Front-panel indicators can be easily read, and access to ports is sufficient for unrestricted cabling. • AC power cord reaches from the power outlet to the rear panel connector. • Access to the switch rear panel to connect the RPS 2300 or the RPS 675. If not, cable the switches before rack-mounting.
Chapter 2 Switch Installation Planning a Switch Stack Planning a Switch Stack If you plan to stack your switches, read these sections: • Stack Guidelines, page 2-6 • Stack Cabling, page 2-6 • Stack Bandwidth and Partitioning Examples, page 2-8 • Power-On Sequence for Switch Stacks, page 2-9 Stack Guidelines For general concepts and procedures see the switch software configuration guide on Cisco.com.
Chapter 2 Switch Installation Planning a Switch Stack In Figure 2-2 the switches are stacked in a vertical rack or on a table. The connections are redundant. Stacking Switches with 0.5-meter and 3-meter Stack Cables 250580 Figure 2-2 Figure 2-3 and Figure 2-4 show switch stacks that use the 3-meter stack cable in addition to the 0.5-meter cable. The connections are redundant.
Chapter 2 Switch Installation Planning a Switch Stack Stack Bandwidth and Partitioning Examples Figure 2-5 shows a stack that provides full bandwidth with redundant connections. Figure 2-5 A Stack with Full Bandwidth Connections 272680 B C Figure 2-6 shows a stack with incomplete stack cabling connections. This stack provides only half bandwidth and does not have redundant connections.
Chapter 2 Switch Installation Installing the Switch Power-On Sequence for Switch Stacks Consider these guidelines before you power on the switches in a stack: • The sequence in which the switches are first powered on might affect the switch that becomes the stack master. • If you want a particular switch to be the stack master, power on that switch first. This switch becomes the stack master and remains the stack master until a master re-election is required.
Chapter 2 Switch Installation Installing the Switch Figure 2-9 Rack-Mounting Brackets 19 inch ETSI 132869 23/24 inch Attaching the Rack-Mount Brackets First remove the screws from the switch chassis so that the mounting brackets can be attached (Figure 2-10). For bracket attachment, remove one or two screws, depending on the bracket mounting position.
Chapter 2 Switch Installation Installing the Switch Use three Phillips flat-head screws to attach the long side of the bracket to each side of the switch (Figure 2-11).
Chapter 2 Switch Installation Installing the Switch Mounting in a Rack After the brackets are attached, use the four supplied Phillips machine screws to attach the brackets to the rack (Figure 2-12). Use the black Phillips machine screw to attach the cable guide to the left or right bracket. When you complete the switch installation, see the “After Switch Installation” section on page 2-16 for more information on switch configuration.
Chapter 2 Switch Installation Installing the Switch Wall-Mounting Warning • Attaching the Brackets for Wall-Mounting, page 2-13 • Attaching the RPS Connector Cover, page 2-14 • Mounting on a Wall, page 2-15 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.
Chapter 2 Switch Installation Installing the Switch Attaching the RPS Connector Cover If you are not using an RPS with your switch, use the two Phillips pan-head screws to attach the RPS connector cover to the back of the switch (Figure 2-14). If an RPS is not connected to the switch, install an RPS connector cover on the back of the switch.
Chapter 2 Switch Installation Installing the Switch Mounting on a Wall For the best support of the switch and cables, make sure that the switch is attached securely to wall studs or to a firmly attached plywood-mounting backboard. Mount the switch with the front panel facing up (Figure 2-15). Warning Mounting on a Wall Catalyst 2975G S eri es Figure 2-15 To comply with safety regulations, mount the switches on a wall with the front panel facing up.
Chapter 2 Switch Installation Connecting to the Stack Ports Table- or Shelf-Mounting To install the switch on a table or shelf, locate the adhesive strip with the rubber feet in the mounting-kit envelope. Attach the four rubber feet to the recessed areas on the bottom of the chassis. Place the switch on the table or shelf near an AC power source. When you complete the switch installation, see the “After Switch Installation” section on page 2-16 for more information on switch configuration.
Chapter 2 Switch Installation Installing SFP Modules Figure 2-16 Inserting the Stack Cable in a Stack Port 1 STACK 2 CONSO LE 132362 STACK Caution Removing and installing the stack cable can shorten its useful life. Do not remove and insert the cable more often than is absolutely necessary. When you need to remove the stack cable from the connector, make sure to fully unscrew the correct screws before removing the connector.
Chapter 2 Switch Installation Installing SFP Modules Installing an SFP Module When installing SFP modules, observe these guidelines: • Do not remove the dust plugs from the SFP modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light. • Removing and installing an SFP module can shorten its useful life.
Chapter 2 Switch Installation 10/100/1000 PoE Port Connections Step 5 Grasp the SFP module, and carefully remove it from the module slot. Step 6 Place the removed SFP module in an antistatic bag or other protective environment. 10/100/1000 PoE Port Connections The 10/100/1000 PoE ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable.
Chapter 2 Switch Installation Where to Go Next Caution Noncompliant cabling or powered devices can cause a PoE port fault. Use only standard-compliant cabling to connect Cisco prestandard IP Phones and wireless access points or IEEE 802.3af-compliant devices. You must remove any cable or device that causes a PoE fault. Step 3 Reconfigure and reboot the connected device if needed. Step 4 Repeat Steps 1 through 3 to connect each device.
C H A P T E R 3 Troubleshooting • Diagnosing Problems, page 3-1 • Clearing the Switch IP Address and Configuration, page 3-4 • Finding the Switch Serial Number, page 3-5 • Replacing a Failed Stack Member, page 3-6 Diagnosing Problems The LEDs on the front panel provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from the device manager, from the CLI, or from an SNMP workstation.
Chapter 3 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). • Examine or swap the copper or fiber-optic cable with a known, good cable.
Chapter 3 Troubleshooting Diagnosing Problems 10/100/1000 PoE Port Connections When a powered device connected to PoE port does not receive power, you should: • Use the Mode button to show the PoE status for all ports. See Table 1-6 and Table 1-7 for descriptions of the LEDs and their meanings. • Verify the port status by using the show interfaces privileged EXEC command to see if the port is in error-disabled, disabled, or shutdown. Re-enable the port if necessary.
Chapter 3 Troubleshooting Clearing the Switch IP Address and Configuration Loops can be caused by a unidirectional link. A unidirectional link occurs whenever the traffic sent by the switch is received by its neighbor, but the traffic from the neighbor is not received by the switch. A broken fiber-optic cable, other cabling, or a port issue could cause this one-way communication. You can enable UniDirectional Link Detection (UDLD) on the switch to help identify unidirectional link problems.
Chapter 3 Troubleshooting Finding the Switch Serial Number Note This procedure clears the IP address and all configuration information stored on the switch. Do not follow this procedure unless you want to completely reconfigure the switch. 1. Press and hold the Mode button (Figure 1-1 on page 1-2). 2. The switch LEDs begin blinking after about 2 seconds. If the switch is not configured, the LEDs above the Mode button turn green. You can omit the next step. 3. Continue holding down the Mode button.
Chapter 3 Troubleshooting Replacing a Failed Stack Member Replacing a Failed Stack Member 1. Get a replacement switch that has the same model number as the failed switch. 2. Power down the failed switch. 3. Make sure that the replacement switch is off, and then connect it to the stack. 4. Make the same connections on the replacement switch that were on the failed switch. 5. Reinstall any modules, and make cable connections. 6. Turn on the replacement switch.
