Installation Guidelines

Before installing the switch, verify that these guidelines are met:

• Clearance to front and rear panels is such that

–

Front-panel indicators 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.

–

The X2-10GB-CX4 transceiver module minimum bend radius and connector length is met. See
the X2 transceiver module documentation for more information.

• For switches that support the RPS 2300, confirm that you have access to the switch rear panel to

connect the RPS 2300. If you do not have access to the rear panel, you should cable the switches
before you rack-mount them.

• For switches with the optional 1150-W power-supply module (C3K-PWR-1150WAC=), first

rack-mount the switch before installing the power-supply module.

• For power-supply modules and fan modules, tighten the module captive screws before moving the

switch.

• When connecting or disconnecting the power cord on a switch that is installed above or below a

1150-W power supply-equipped switch, you might need to remove the module from the switch to
access the power cord.

Preparing for Installation

• 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.

• 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 X2 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 required 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.

These standards provide guidelines for acceptable working environments and acceptable levels of
suspended particulate matter:

Planning a Switch Stack (Catalyst 3750-E Switches)

Box Contents

The box contents are described in the switch getting started guide. If any item is missing or damaged,
contact your Cisco representative or reseller for support.

Tools and Equipment

You need to supply a number-2 Phillips screwdriver to rack-mount the switch. For connecting the
StackWise cables, you need a ratcheting torque screwdriver capable of 5 lbf-in. (80 ozf-in.).

Planning a Switch Stack (Catalyst 3750-E Switches)

If you plan to stack your switches, read these sections:

• Switch Stacking Guidelines, page 2-6

• Stack Cabling Configurations, page 2-7

• Stack Bandwidth and Partitioning Examples, page 2-8

• Power On Sequence for Switch Stacks, page 2-9

Switch Stacking Guidelines

For general concepts and procedures to manage switch stacks, see the switch software configuration
guide on Cisco.com. When adding a Catalyst 3750-E switch to an existing 3750 switch stack, review the
Catalyst 3750-E Switch Stack Compatibility Guide on Cisco.com for information about mixed stack
configurations.

Before connecting the switches in a stack, keep in mind these stacking guidelines:

• Size of the switch and any optional power-supply module. The 1150-W power-supply module is

longer than the other modules. Stacking switches with the same power-supply modules together
makes it easier to cable the switches. For switch dimensions, see Appendix A, “Technical

Specifications.”

• Length of cable. Depending on the configurations that you have, you might need different sized

cables. If you do not specify the length of the StackWise cable, the 0.5-meter cable is supplied. If
you need the 1-meter cable or the 3-meter cable, you can order it from your Cisco supplier. For cable
part numbers, see the “StackWise Ports” section on page 1-14. The “Stack Cabling Configurations”

section on page 2-7 provides examples of recommended configurations.

• Access to the switch rear panel and to the rear of the rack if you are planning to stack the switches.

If you do not have access to the rear panel, make sure that you cable the switches before you
rack-mount them.

• For switch stacks that are rack-mounted, review this recommended sequence of events:

–

If you are using the RPS 2300, install the RPS first at the bottom of the stack. If needed, allow
one RU space between the RPS and the first switch above to provide room for cabling.

–

Connect all the 22-pin RPS cables to the RPS 2300 as needed.

–

Rack-mount the switches. If you have the optional 1150-W power-supply module, first
rack-mount the switch before installing the power-supply module.

–

Connect the RPS cable to the first switch above the RPS 2300. Connect the stack cables to the
first switch above the RPS.

–

Connect the RPS cable to the next switch above the RPS 2300. Connect the stack cables to the
next switch above the RPS.

–

Repeat until all devices are connected.

Stack Cabling Configurations

This section describes the recommended cabling configurations for stacking the switches.

Figure 2-1 is an example of a recommended configuration that uses the supplied 0.5-meter StackWise

cable. In this example, the switches are stacked in a vertical rack or on a table. This configuration
provides redundant connections.

Figure 2-7 and Figure 2-8 show examples of stacks of Catalyst 3750-E switches with failover conditions.

In Figure 2-7, the StackWise cable is bad in link B; therefore, this stack provides only half bandwidth
and does not have redundant connections. In Figure 2-8, link B is bad; therefore, this stack partitions into
two stacks, and switch 1 and switch 3 are stack masters.

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 become the stack master, power on that switch first. This switch

becomes the stack master and remains the stack master until a master re-election is required. After
1 minute, power on the other switches in the stack.

• 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.
