Installation Guidelines
When determining where to install the switch, verify that these guidelines are met:
•Clearance to the switch front and rear panel meets 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 rear panel.
– Access to the rear of the rack is sufficient for connecting StackWise cables to stacked switches,
or connecting the optional Cisco Redundant Power Supply (RPS) 2300
•Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures. Make sure the cabling is safely away from other devices that might damage the
cables.
•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.
Operating environment is within the ranges listed in Appendix 1, “Technical Specifications.”
•Humidity around the switch does not exceed 85 percent.
•Altitude at the installation site is not greater than 10,000 feet.
•For 10/100 and 10/100/1000 fixed ports, the cable length from a switch to a connected device cannot
exceed 328 feet (100 meters).
•For cable lengths for SFP-module connections, see the “Cables and Adapters” section on page 1-3.
•Cooling mechanisms, such as fans and blowers in the switch, 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.
Box Contents
The switch getting started guide describes the box contents. If any item is missing or damaged, contact
your Cisco representative or reseller for support.
Tools and Equipment
Obtain these necessary tools and equipment:
•A number-2 Phillips screwdriver to rack-mount the switch.

Planning a Switch Stack
Verifying Switch Operation
Before you install the switch in a rack, on a wall, or on a table or shelf, power on the switch and verify
that it passes POST.
To power on the switch, plug one end of the AC power cord into the switch AC power connector, and
plug the other end into an AC power outlet.
As the switch powers on, it begins the POST, a series of tests that runs automatically to ensure that the
switch functions properly. LEDs can blink during the test. POST lasts approximately 1 minute. When
the switch begins POST, the System, RPS, Status, Duplex, and Speed LEDs turn green. The System LED
blinks green, and the other LEDs remain solid green.
When the switch completes POST successfully, the System LED remains green. The RPS LED remains
green for some time and then reflects the switch operating status. The other LEDs turn off and then
reflect the switch operating status. If a switch fails POST, the System LED turns amber.
POST failures are usually fatal. Call Cisco technical support representative if your switch fails POST.
After a successful POST, unplug the power cord from the switch. Install the switch in a rack, on a wall,
on a table, or on a shelf as described in the “Installing the Switch” section on page 1-10.
If your configuration has an RPS, connect the switch and the RPS to different AC power sources. See
the Cisco RPS documentation for information.
Note When you connect the RPS to the switch, put the RPS in standby mode. Set the RPS to active mode
during normal operation.
Warning Attach only the following Cisco RPS model to the RPS receptacle: PWR-RPS2300 = Statement 370
Planning a Switch Stack
Note This section applies only to the Catalyst 2960-S stacking-capable switches.
Stack Guidelines
•Connect only Catalyst 2960-S switches in a switch stack. You cannot stack the Catalyst 2960-S with
other switches such as the Catalyst 2975, 3550, 3560, or 3750 switches.
•Stack only up to four switches.
•Install the FlexStack module and the FlexStack cable. You can order them from your Cisco sales
representative: C2960S-STACK=.
Note The FlexStack module is hot-swappable and can be inserted while the switch is powered on.
•Order the appropriate cable from your Cisco sales representative. The length of FlexStack cable
depends on your configuration. These are the different sizes available:

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. After 2 minutes,
power on the other stack switches.
•If you have no preference as to which switch becomes the stack master, power on all the switches in
the stack within a 1-minute timeframe. These switches participate in the stack master election.
Switches powered on after the 1-minute timeframe do not participate in the election.
•Power off a switch before you add it to or remove it from an existing switch stack.
For conditions that can cause a stack master re-election or to manually elect the stack master, see the
“Managing Switch Stacks” chapter in the switch software configuration guide on Cisco.com.

Installing SFP and SFP+ Modules
Some switch models support SFP modules, SFP+ modules, or both. The SFP slots support only the SFP
modules. The slots marked SFP+ slots support both SFP and SFP+ modules.
See the “SFP and SFP+ Module Slots” section on page 1-8 and the switch release notes on Cisco.com
for the list of supported SFP modules. Use only Cisco SFP modules on the switch. Each Cisco module
has an internal serial EEPROM that is encoded with security information. This encoding provides a way
for Cisco to identify and validate that the module meets the requirements for the switch.
For information about installing, removing, cabling, and troubleshooting SFP modules, see the module
documentation that shipped with your device. For module cable specifications, see Appendix 1,
“Connector and Cable Specifications.”
