Preparing for Installation
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.
•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:
– Network Equipment Building Systems (NEBS) GR-63-CORE
– National Electrical Manufacturers Association (NEMA) Type 1
– International Electrotechnical Commission (IEC) IP-20

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.

Chapter 2 Switch Installation
Stack Cabling Configurations
– 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 2-1 Stacking the Switches in a Vertical Rack or on a Table Using the 0.5-meter StackWise
Cable
The configuration examples in Figure 2-2 use the 3-meter StackWise cable in addition to the supplied
0.5-meter StackWise cable. This configuration also provides redundant connections.

Stack Cabling Configurations
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.
Figure 2-7 Example of a Stack with a Failover Condition
Figure 2-8 Example of a Partitioned Stack with a Failover Condition
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.

Connecting to the StackWise Ports (Catalyst 3750-E Switches)
Before connecting the StackWise cables, review the “Planning a Switch Stack (Catalyst 3750-E
Switches)” section on page 2-6. Always use a Cisco-approved StackWise cable to connect the switches.
Follow these steps to connect the StackWise cable to the StackWise ports:
Step 1 Remove the dust covers from the StackWise cables and StackWise ports, and store them for future use.
Step 2 Use the window in the StackWise cable to align the connector correctly. Insert the cable into the
StackWise port on the back of the switch (Figure 2-16). Using a ratcheting torque screwdriver, tighten
the retainer screws to 5 lbf-in. (80 ozf-in.).
Step 3 Insert the other end of the cable into the connector of the other switch, and tighten the retainer screws to
5 lbf-in. (80 ozf-in.). Avoid overtightening the screws.
Figure 2-16 Inserting the StackWise Cable in a StackWise Port
Caution Removing and installing the StackWise cable can shorten its useful life. Do not remove and
insert the cable more often than is absolutely necessary.
When you need to remove the StackWise cable from the connector, make sure to fully unscrew the
correct screws before removing the connector. When the connectors are not being used, replace the dust
covers to protect them from dust.

These sections describe how to install and remove X2 transceiver modules and the Cisco TwinGig
Converter Modules (also known as converter modules).
Use only Cisco X2 transceiver modules, converter modules, and SFP modules with 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 more information about installing, removing, cabling, and troubleshooting X2 transceiver modules,
see the module documentation that shipped with your device. For module cable specifications, see
Appendix B, “Connector and Cable Specifications.”
Installing X2 Transceiver Modules and Converter Modules
When installing X2 transceiver modules and converter modules, observe these general precautions:
•When you install or remove the converter module, the mode on the switch changes from 10-Gigabit
Ethernet to Gigabit Ethernet or the reverse. During this mode change, data traffic on the other switch
uplink ports (X2 transceiver or SFP module ports) might temporarily stop. When you install or
remove an X2 transceiver or SFP module, traffic delay does not occur.
•Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install an X2
transceiver or a converter module. Either a module or an EMC plug must be installed in the slot at
all times.
•Do not remove the dust plugs from the fiber-optic X2 transceiver modules or the rubber caps from
the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module
ports and cables from contamination and ambient light.
•Removing and installing an X2 module can shorten its useful life. Do not remove and insert any X2
module more often than is absolutely necessary.
•To prevent ESD damage, follow your normal board and component handling procedures when
connecting cables to the switch and other devices.
To install an X2 transceiver module or a converter module, follow these steps:
Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.
Step 2 Remove the module from the protective packaging.
Step 3 Remove the 10-Gigabit Ethernet module slot EMC plug and save.
Caution Verify the correct orientation of your module before inserting it into the slot. Incorrect insertion can
damage the module.
Step 4 For 24- and 48-port switches, position the module face up to install in the upper module slot (slot 1).
Position the module face down to install in the lower module slot (slot 2). See Figure 2-17 and
Figure 2-19. Slide the module into the opening until the back of the module faceplate is flush with the
switch faceplate.
For Catalyst 3560E-12D switches, position the module top facing right to install in a module slot. See
Figure 2-18 and Figure 2-20. Slide the module into the opening until the back of the module faceplate is
flush with the switch faceplate.

Installing Devices in the 10-Gigabit Ethernet Slots
For Catalyst 3560E-12SD switches, position the module face up to install in the upper module slot
(slot 1). Position the module face down to install in the lower module slot (slot 2). See Figure 2-17 and
Figure 2-19. Slide the module into the opening until the back of the module faceplate is flush with the
switch faceplate.
Caution Do not insert or remove an X2 transceiver module with fiber-optic cables attached. An X2 module
interface might go into an error-disabled state when an X2 transceiver module is inserted or removed
with fiber-optic cables connected to the module. If the interface is in an error-disabled state, you can
re-enable the interface by using the shutdown and no shutdown interface configuration commands.
