23 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Catalyst 2960-S Switch Getting Started Guide Connecting the FlexStack Cables Always use a Cisco-approved FlexStack cable to connect the switches. Connect only Catalyst 2960-S switches in a switch stack. Step 1Remove the dust covers from the FlexStack cables, and store them for future use. Step 2Insert one end of the FlexStack cable into the stack port of the first switch. Insert the other end of the cable into the stack port on the other switch. NoteWhen you connect the FlexStack cable into the STACK 1 port, the tab should be above the connector. When you connect the FlexStack cable into the STACK 2 port, you should invert the cable so that the tab is below the connector. Step 3Replace the dust covers when you remove the FlexStack cables from the connectors. Removing and installing the FlexStack cable can shorten its useful life. Do not remove and insert the cable more often than is absolutely necessary. 206235
Catalyst 2960-S Switch Getting Started Guide 24 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Connecting to the Switch Ports This section describes how to connect to the fixed switch ports and to the SFP module ports. Connect to the 10/100 or 10/100/1000 Ports The fixed ports on the Catalyst 2960-S Power over Ethernet Plus (PoE+) switches provide: PoE+ support for IEEE 802.3at-compliant powered devices PoE support for IEEE 802.3af-compliant powered devices Support for Cisco enhanced PoE (ePoE) They also provide Cisco prestandard PoE support for Cisco IP phones and Cisco Aironet Access Points. See the switch hardware guide for information on PoE budgeting. By default, a Catalyst 2960-S switch PoE port automatically provides power when a compliant device is connected, including ePoE, PoE, and PoE+. For information about configuring and monitoring PoE and PoE+ ports, see the switch software configuration guide. Step 1When you connect to servers, workstations, IP phones, wireless access points, and routers, insert a straight-through, twisted four-pair, Category 5 cable in a switch 10/100 or 10/100/1000 port. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters. Step 2Insert the other cable end into an RJ-45 port on the other device. 11X 14X 12X 1X 2X11X POWER OVER ETHERNET 740W 206236
25 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Catalyst 2960-S Switch Getting Started Guide NoteThe automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default. The switch detects the required cable type for copper Ethernet connections and configures the interfaces accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a copper 10/100 or 10/100/1000 module port on the switch, regardless of the type of device on the other end of the connection. Install the SFP or SFP+ Modules Some Catalyst 2960-S switches have SFP module slots and others have SFP+ module slots. The SFP slots support only the SFP modules. The SFP+ slots support both SFP and SFP+ modules. For a list of supported modules, see the release notes on Cisco.com. For detailed instructions on installing, removing, and connecting to SFP modules, see the documentation that came with the SFP module. CautionRemoving and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary. Step 1Grasp the module on the sides, and insert it into the switch slot until you feel the connector snap into place. Step 2Insert an appropriate cable into the module port. Insert the other cable end into the other device. 47X 48X 1 2 Catalyst 2960-S Series PoE+ 10G 206237 47X 48X 1 2 Catalyst 2960-S Series PoE+ 10G
Catalyst 2960-S Switch Getting Started Guide 26 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Verify Port Connectivity After you connect the switch port and another device, the port LED turns amber while the switch establishes a link. This process takes about 30 seconds, and then the LED turns green. If the LED turns off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device. See the “In Case of Difficulty” section on page 26 for information about online assistance. In Case of Difficulty If you experience difficulty, help is available in this section and also on Cisco.com. This section includes Express Setup troubleshooting, how to reset the switch, how to access help online, and where to find more information. Troubleshooting Express Setup If Express Setup does not run, or if the Express Setup page does not appear in your browser: Did you verify that POST ran successfully before starting Express Setup?If not, make sure that only the SYST and STAT LEDs are green before you press the Mode button to enter the Express Setup mode. POST errors are usually fatal. Contact your Cisco technical support representative if your switch fails POST. Did you press the Mode button while the switch was still running POST?If yes, wait until POST completes. Power cycle the switch. Wait until POST completes. Confirm that the SYST and STAT LEDs are green. Press the Mode button to enter Express Setup mode.
27 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Catalyst 2960-S Switch Getting Started Guide Did you try to continue without confirming that the switch was in Express Setup mode?Verify that all LEDs above the Mode button are green. (The RPS LED is off.) If necessary, press the Mode button to enter Express Setup mode. Does your PC have a static IP address?If yes, before connecting to the switch, change your PC settings to temporarily use DHCP. Did you connect a crossover cable instead of a straight-through Ethernet cable between a switch port and the Ethernet port of the PC?If yes, connect a straight-through cable to an Ethernet port on the switch and the PC. Wait 30 seconds before you enter 10.0.0.1 in the browser. Did you connect the Ethernet cable to the console port instead of to a 10/100 or 10/100/1000 Ethernet port on the switch?If yes, disconnect the cable from the console port. Then connect the cable to an Ethernet port on the switch and the PC. Wait 30 seconds before you enter 10.0.0.1 in the browser. NoteThe console port is outlined in blue, and the Ethernet port is outlined in yellow. Did you wait 30 seconds after you connected the switch and the PC before you entered the IP address in your browser?If not, wait 30 seconds, re-enter 10.0.0.1 in the browser, and press Enter. Did you enter the wrong address in the browser, or is there an error message?If yes, re-enter 10.0.0.1 in the browser, and press Enter.
Catalyst 2960-S Switch Getting Started Guide 28 Catalyst 2960-S Switch Getting Started Guide OL-19793-02 Resetting the Switch Follow these steps to return your switch to the factory default settings. These are reasons why you might want to reset the switch: You installed the switch in your network and cannot connect to it because you assigned the wrong IP address. You want to clear all configurations from the switch and assign a new IP address. You want to reset the password on the switch. CautionResetting the switch deletes the configuration and reboots the switch. To reset the switch: Press and hold the Mode button. The switch LEDs begin blinking after about 3 seconds. Continue holding down the Mode button. The LEDs stop blinking after 7 more seconds, and then the switch reboots. The switch now behaves like an unconfigured switch. You can enter the switch IP information by using Express Setup as described in the “Running Express Setup” section on page 4. Accessing Help Online First look for a solution to your problem in the troubleshooting section of the switch hardware installation guide or the switch software configuration guide on Cisco.com. You can also access the Cisco Technical Support and Documentation website for a list of known hardware problems and extensive troubleshooting documentation.
