Chapter 2 Switch 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.

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:

–

Network Equipment Building Systems (NEBS) GR-63-CORE

–

National Electrical Manufacturers Association (NEMA) Type 1

–

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.

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.

Chapter 2 Switch Installation

Installing Devices in the 10-Gigabit Ethernet Slots

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

Installing SFP Modules

This section describes how to install and remove SFP modules in the 3560E-12SD switch slots and in the Cisco TwinGig Converter Module slots. For 24- and 48-port switches and Catalyst 3560E-12D switches, you must have a converter module installed in a 10-Gigabit Ethernet slot to use SFP modules.

See the “SFP Modules” section on page 1-5 and the switch release notes on Cisco.com for the list of SFP modules that the switch supports. 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 more information about installing, removing, cabling, and troubleshooting SFP modules, see the module documentation that shipped with your device. For module cable specifications, see Appendix B,

“Connector and Cable Specifications.”

Chapter 2 Switch Installation

Installing an SFP Module

When installing SFP modules, observe these general precautions:

• Do not remove the dust plugs from the SFP 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 SFP module can shorten its useful life. Do not remove and insert any

SFP 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 SFP module, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Caution To avoid damage to the converter module, first install the converter module in the switch 10-Gigabit

Ethernet slot before installing the SFP modules.

Installing SFP Modules

Step 2 For switches without SFP module slots, install a converter module in the 10-Gigabit Ethernet module

slot as described in the “Installing X2 Transceiver Modules and Converter Modules” section on

page 2-19.

Step 3 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the direction of the connection, either send or receive (TX or RX).

Step 4 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Step 5 For 24- and 48-port switches, position the SFP module face up to install in the upper converter module

slot (slot 1). Position the module face down to install in the lower converter module slot (slot 2). See

Figure 2-21.

For Catalyst 3560E-12D switches, position the SFP module top facing right to install in a converter module slot. See Figure 2-22.

For Catalyst 3560E-12SD switches, position the SFP module face up to install it in a module slot. See

Figure 2-23. For an example of installing SFPs in a converter module, see Figure 2-21.

Step 6 If the module has a bale-clasp latch, close it to lock the SFP module in place.

Step 7 Remove the SFP dust plugs and save.

Step 8 Connect the SFP cables.

Removing an SFP Module

To remove an SFP module from a module slot, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface.

Step 2 Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send

(TX) and which is receive (RX).

Step 3 Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean.

Step 4 If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp

latch is obstructed and you cannot use your index finger to open it, use a small, flat-blade screwdriver or other long, narrow instrument to open the bale-clasp latch.

Step 5 Grasp the SFP module, and carefully remove it from the module slot.

Step 6 Place the removed SFP module in an antistatic bag or other protective environment.

Connecting Devices to the Ethernet Ports

This section includes these topics:

• 10/100/1000 Ethernet Port Connections, page 2-26

• PoE Port Connections, page 2-26

Caution Category 5e and Category 6 cables can store high levels of static electricity. Always ground the cables

to a suitable and safe earth ground before connecting them to the switch or other devices.

Connecting Devices to the Ethernet Ports

10/100/1000 Ethernet Port Connections

The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.

The autonegotiation feature is enabled by default on the switch. At this setting, the switch ports configure themselves to operate at the speed of attached device. If the attached device does not support autonegotiation, you can explicitly set the switch port speed and duplex parameters. To maximize performance, either let the ports autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the connection.

For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is enabled by default on the switch. With auto-MDIX enabled, the switch detects the required cable type for copper Ethernet connections and configures the interface accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a switch 10/100/1000 Ethernet port regardless of the type of device on the other end of the connection.

See the switch software configuration guide or the switch command reference on Cisco.com for more information about enabling or disabling autonegotiation and auto-MDIX.

If auto-MDIX is disabled, use the guidelines in Tab le 2-1 to select the correct cable for connecting the switch 10/100/1000 Ethernet ports to other devices. See the “Cable and Adapter Specifications” section

on page B-5 for cable-pinout descriptions.

Chapter 2 Switch Installation

1. 100BASE-TX and 1000BASE-T traffic requires twisted four-pair, Category 5, Category 5e, or Category 6 cable. 10BASE-T traffic can use Category 3 or Category 4 cable.

PoE Port Connections

The 10/100/1000 PoE ports have the same autonegotiation settings and cabling requirements that are described in the “10/100/1000 Ethernet Port Connections” section on page 2-26.

The PoE ports provide PoE support for devices compliant with IEEE 802.3af and also provide Cisco pre-standard PoE support for Cisco IP Phones and Cisco Aironet Access Points.

Each port can deliver up to 15.4 W of PoE. With the 1150-W power-supply module, the Catalyst 3750E-48PS and Catalyst 3560E-48PS switches can deliver 15.4 W on all 48 ports. With the 750-W power-supply module, the switches can deliver 15.4 W of PoE on any 24 of the 48 ports, or any combination of the ports can deliver an average of 7.7 W of PoE at the same time, up to a maximum switch power output of 370 W. On a per-port basis, you can control whether or not a PoE port automatically provides power when an IP phone or an access point is connected.

Chapter 2 Switch Installation

Note On 48-port PoE switches, you must use the 1150-W power-supply module to provide full 15.4-W

capability across all 48 ports.

To access an advanced PoE planning tool, use the Cisco Power Calculator available on Cisco.com at this URL:

http://tools.cisco.com/cpc/launch.jsp

You can use this application to calculate the power supply requirements for a specific PoE configuration. The results show output current, output power, and system heat dissipation.

You must be a registered Cisco.com user to access the Cisco Power Calculator. If you do not have a user ID or password, you can register at this URL:

http://tools.cisco.com/RPF/register/register.do

For more information about the required power-supply module and the PoE specifications, see the

“Power-Supply Modules” section on page 1-15, and Appendix A, “Technical Specifications.”

Note Many legacy powered devices, including older Cisco IP phones and access points that do not fully

support IEEE 802.3af, might not support PoE when connected to the switches by a crossover cable.

Connecting Devices to the Ethernet Ports

Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Only

standard-compliant cabling can be used to connect Cisco pre-standard IP Phones and wireless access points or IEEE 802.3af-compliant devices to PoE ports. A cable or device that causes a PoE fault must be removed from the network.

Where to Go Next

If the default configuration is satisfactory, the switch does not need further configuration. You can use any of these management options to change the default configuration:

• Start the device manager, which is in the switch memory, to manage individual and standalone

switches. This is an easy-to-use web interface that offers quick configuration and monitoring. You can access the device manager from anywhere in your network through a web browser. For more information, see the switch getting started guide and the device manager online help.

• Start the Network Assistant application, which is described in the Getting Started with Cisco

Network Assistant guide. Through this GUI, you can configure and monitor a switch cluster or an

individual switch.

• Use the CLI to configure the switch as a member of a cluster or as an individual switch from the

console. See the switch command reference on Cisco.com for information on using the CLI with the switch.

• Start an SNMP application such as the CiscoView application.
