Installing the Switch

This section describes rack-mounting using 19-inch and 23-inch rack-mounting brackets. For optional bracket information and alternate mounting procedures, such as installing the switch in a 24-inch rack or on a wall, and for additional cabling information, see the Hardware Installation Guide on Cisco.com.

Tools and Equipment

Obtain these necessary tools:

  • A Number-2 Phillips screwdriver.

  • Drill with #27 drill bit (0.144-inch [3.7 mm]) for mounting an 8-port and 16-port switch.

Installation Guidelines

When determining where to install the switch, verify that these guidelines are met:

  • Clearance to the switch's front and rear panel should meet these conditions:

    • Front-panel LEDs can be easily read.

    • Access to ports is sufficient for unrestricted cabling.

    • AC power cord can reach from the AC power outlet to the connector on the switch's rear panel.

  • Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.

  • Airflow around the switch and through the vents is unrestricted. To avoid any flow blockage, we strongly recommend these guidelines:

    • Allow at least 3 in. (7.6 cm) of clearance from the left and the right sides, and the front and rear of the switch.

    • Allow at least 1.75 in. (4 cm) of clearance from the top cover, if you are installing the switch in upright position.

    • Allow at least 3 in. (7.6 cm) of clearance from the top cover, if you are installing the switch inverted, under a table.

    • Allow at least 1 RU of empty rack space above the switch, if you are installing the switch in a rack.

  • Temperature around the unit does not exceed 113°F (45°C). If the switch is installed in a closed or multirack assembly, the temperature around it might be greater than normal room temperature.

  • Humidity around the switch does not exceed 95 percent.

  • Altitude at the installation site is not greater than 10,000 feet.

  • For 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot exceed 328 feet (100 meters).

  • Cooling mechanisms, such as fans and blowers in the switch, can draw dust and other particles causing contaminant build-up inside the chassis, which can result in system malfunction. You must install this equipment in an environment as free from dust and foreign conductive material (such as metal flakes from construction activities) as is possible.

  • None of the switch models can be deployed outside of the wiring closet. These switches can only be deployed indoors.

Desk-Mounting or Shelf-Mounting the Switch

Mounting on a Desk or Shelf Without Mounting Screws

Procedure

Step 1

Locate the adhesive strip with the rubber feet in the accessory kit.

Step 2

Remove the four rubber feet from the adhesive strip, and attach them to the recessed areas at the bottom of the unit. This prevents the switch from sliding on the desk or shelf.

Note 
We strongly recommend that you attach the rubber feet. Doing so also helps prevent airflow restriction and overheating.
    Step 3

    Place the switch on the desk or shelf.

    Mounting on a Desk or Shelf with Mounting Screws


    Note
    This procedure is applicable only for 8-port and 16-port switch models.

    Procedure

    Step 1

    Use the screw template to align the mounting screw holes and also as a guide to make sure that you install the screws into the desk or shelf with proper clearance.

    Step 2

    Position the screw template on top of the desk or shelf so that the edge that is marked as CABLE SIDE ENTRY faces the front of the desk or shelf. This ensures that the power cord faces the rear of the desk or shelf after the switch is installed.

    Step 3

    Peel the adhesive strip off the bottom of the screw template and attach it to the top of the desk or shelf.

    Step 4

    Use a 0.144-inch (3.7 mm) or a #27 drill bit to drill a 1/2-inch (12.7 mm) hole in the two screw template slots.

    Step 5

    Insert two screws into the slots on the screw template, and tighten them until they touch the top of the screw template.

    Connecting to the Switch Ports

    This section describes how to connect to the fixed switch ports and to the Small Form-Factor Pluggable (SFP) module ports.

    Connecting to the 10/100/100 or 10/100/1000 PoE+ Ports

    The fixed ports on the Cisco Catalyst 2960-L 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

    These ports also provide Cisco prestandard PoE support for Cisco IP phones and Cisco Aironet Access Points. See the Cisco Catalyst 2960-L Hardware Installation Guide for information on PoE budgeting. By default, a switch PoE port automatically provides power when a compliant device is connected, including PoE, and PoE+.


    Note

    The 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 10/100/1000 module port on the switch, regardless of the type of device at the other end of the connection.

    SUMMARY STEPS

    1. Insert a straight-through, twisted four-pair, Category 5 cable in a switch's 10/100/1000 port when you connect to servers, workstations, IP phones, wireless access points, and routers. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.
    2. Insert the other cable end into an RJ-45 port on the other device.

    DETAILED STEPS

    Step 1

    Insert a straight-through, twisted four-pair, Category 5 cable in a switch's 10/100/1000 port when you connect to servers, workstations, IP phones, wireless access points, and routers. Use a crossover, twisted four-pair, Category 5 cable when you connect to other switches, hubs, or repeaters.

    Step 2

    Insert the other cable end into an RJ-45 port on the other device.

    Connecting to SFP Module Slots

    For a list of supported modules, see the Cisco Catalyst 2960-L 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.


    Caution

    Removing and installing an SFP module can shorten its useful life. Do not remove and insert SFP modules more often than is absolutely necessary.

    SUMMARY STEPS

    1. Grasp the module on the sides, and insert it into the switch slot until you feel the connector snapping into place.
    2. Insert an appropriate cable into the module port. Insert the other cable end into the other device.

    DETAILED STEPS

    Step 1

    Grasp the module on the sides, and insert it into the switch slot until you feel the connector snapping into place.



    Step 2

    Insert an appropriate cable into the module port. Insert the other cable end into the other device.

    Verifying 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.

    Troubleshooting

    If you experience a difficulty, help is available in this section and also on Cisco.com. This section includes Express Setup troubleshooting information, details about how to reset the password, and where to find additional information.
