Planning a Switch Data Stack
Operating environment is within the ranges listed in AppendixA, “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

Obtain these necessary tools and equipment:
A number-2 Phillips screwdriver to rack-mount the switch.
A Torx T15 screwdriver, or the Torx T15 key that ships with StackWise upgrade kits, to install the
StackWise adapter.

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.
Planning a Switch Data Stack
Catalyst 3650 switches can share bandwidth by using data stacking.
