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.

Operating environment is within the ranges listed in Appendix A, “Technical Specifications.”

Airflow around the switch and through the vents is unrestricted.

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.

Cisco Ethernet switches are equipped with cooling mechanisms, such as fans and blowers. However, these fans and blowers can draw dust and other particles, causing contaminant buildup 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.

Tools and Equipment

You need to supply a number-2 Phillips screwdriver to rack-mount the switch, to install network modules, and to install StackPower cables.

Verifying Switch Operation

Before you install the switch in a rack, or on a table or shelf, you should power on the switch and verify that the switch passes POST. See the “Running Express Setup” section in the getting started guide for the steps required to connect a PC to the switch and to run Express Setup.

Powering Off the Switch

After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a table, or on a shelf as described in the Chapter 2, “Installing the Switch,” section.
