The maximum cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5, Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use Category 3 or Category 4 UTP cable. For information about the 10/100/1000 Ethernet port connections and specifications, see the “10/100/1000 Ethernet Port Connections” section on page 2-28 and Appendix B, “Connector and Cable Specifications.” PoE+ Ports The PoE+ ports use the same connectors as described in the previous section and provide this support. • Support for IEEE 802.3af compliant powered devices (up to 15.4 W) • Support for IEEE 802.3at compliant powered devices (up to 30 W) • Support for Cisco enhanced PoE • Support for prestandard Cisco powered devices Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 1-3 Chapter 1 Product Overview Front Panel Description • Configuration for StackPower PoE+. When the switch internal power supply module(s) cannot support the total load, StackPower configurations allow the switch to leverage power available from other switches (only Catalyst 3750-X switches) • Configurable support for Cisco intelligent power management, including enhanced power negotiation, power reservation, and per-port power policing Depending on the installed power supply modules, each port can deliver up to 30 W of PoE+. See Table 1-17 for the power supply matrix that defines the available PoE and PoE+ power per port. Note The output of the PoE+ circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1. For information about power supply modules, PoE+ port connections, and PoE+ specifications, see the “Power Supply Modules” section on page 1-17, the “PoE+ Port Connections” section on page 2-28, and Appendix B, “Connector and Cable Specifications.” Network Modules The switch has one hot-swappable network module that provides SFP and SFP+ uplink ports to connect to other devices. You must insert the network module during switch operation. Operating the switch without a network module is not supported. A blank module is available. The switch generates logs when you insert or remove a network module with SFP ports. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 1-4 OL-19593-01 Chapter 1 Product Overview Front Panel Description Table 1-3 Network Modules Network Module1 Description Blank This module has no uplink ports. 1-Gigabit Ethernet This module has four 1-Gigabit SFP module slots. Any combination of standard SFP modules are supported. SFP+ modules are not supported. If you insert an SFP+ module in the 1-Gigabit network module, the SFP+ module does not operate, and the switch logs an error message. 10-Gigabit Ethernet This module has four slots. Two slots support only 1-Gigabit SFP modules, two slots support either 1-Gigabit SFP or 10-Gigabit SFP+ modules. The four slots are grouped as two pairs with each pair consisting of one SFP slot and one SFP+ slot. Each pair supports either two 1-Gigabit SFP modules or one 10-Gigabit SFP+ module. A 10-Gigabit SFP+ module cannot operate at the same time as the corresponding 1-Gigabit SFP module in the pair. Supported combinations of SFP and SFP+ modules: • Slots 1, 2, 3, and 4 populated with 1-Gigabit SFP modules. • Slots 1 and 2 populated with 1-Gigabit SFP modules and Slot 4 populated with one 10-Gigabit SFP+ module. • Slot 2 populated with one 10-Gigabit SFP+ module and Slots 3 and 4 populated with 1-Gigabit SFP modules. • Slot 2 and Slot 4 each populated with 10-Gigabit SFP+ modules. A 10-Gigabit SFP+ module takes precedence over a 1-Gigabit SFP module except when an SFP module is first inserted in Slot 1 and has link. When you insert an SFP+ module in Slot 2, the SFP in Slot 1 retains link. The SFP+ module in Slot 2 does not operate. When the SFP module in Slot 1 is shutdown, loses link, or is removed, the SFP+ module in Slot 2 becomes operational. At this point, the SFP module in Slot 1 will not become operational under any circumstance for as long as an SFP+ module remains in Slot 2 whether it is link up or not. The same precedence applies to Slots 3 and 4. 1. All network modules are hot-swappable. For information about the network modules, see the “Installing a Network Module in the Switch” section on page 2-23. For cable specifications, see Appendix B, “Connector and Cable Specifications.” SFP and SFP+ Modules The switch-Gigabit Ethernet SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These transceiver modules are field-replaceable, providing the uplink interfaces when installed in an SFP module slot. The SFP modules have LC connectors for fiber-optic connections or RJ-45 connectors for copper connections. Use only Cisco SFP modules on the switch.

Blinking amber The power supply in a switch has failed, and the XPS is providing power to that switch (redundancy has been allocated to this device). Port LEDs and Modes Each Ethernet port and 10-Gigabit Ethernet module slot has a port LED. These port LEDs, as a group or individually, display information about the switch and about the individual ports. The port mode determines the type of information shown by the port LEDs. Table 1-8 lists the mode LEDs and their associated port modes and meanings. To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change. Table 1-9 explains how to interpret the port LED colors in different port modes. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 1-9 Chapter 1 Product Overview Front Panel Description When you press the Mode button on any switch in the Catalyst 3750-X switch stack, all the stack switches change to show the same selected mode.

The interface supports Cisco USB flash drives with capacities from 64 MB to 1 GB. Cisco IOS software provides standard file system access to the flash device: read, write, erase, and copy, as well as formatting of the flash device with a FAT file system. You can boot the switch from a USB drive. For information about the switch management ports, see the switch software configuration guide and the command reference on Cisco.com and the “Connector and Cable Specifications” section on page B-1. StackWise Ports The Catalyst 3750-X switch ships with a 0.5-meter StackWise cable (CAB-STACK-50CM) that you can use to connect the StackWise ports. Caution Use only approved cables (CAB-STACK-50CM, CAB-STACK-1M, CAB-STACK-3M, CAB-STACK-50CM-NH,CAB-STACK-1M-NH, or CAB-STACK-3M-NH), and connect only to similar Cisco equipment. Equipment might be damaged if connected to nonapproved Cisco cables or equipment. You can order these StackWise cables from your Cisco sales representative: • CAB-STACK-50CM (0.5-meter cable) • CAB-STACK-1M= (1-meter cable) • CAB-STACK-3M= (3-meter cable) Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 1-16 OL-19593-01 Chapter 1 Product Overview Rear Panel Description • CAB-STACK-50CM-NH= (0.5-meter cable, nonhalogen) • CAB-STACK-1M-NH= (1-meter cable, nonhalogen) • CAB-STACK-3M-NH= (3-meter cable, nonhalogen) Power Supply Modules The 24- and 48-port switches are powered through one or two internal power supply modules. The “Switch Power Supply Modules” section on page 1-17 and Table 1-16 describe the supported power supply modules. Switch Power Supply Modules The switch has two internal power supply module slots. You can use two AC modules, two DC modules, a mixed configuration of one AC and one DC power supply module, or one power supply module and a blank module. The switch can operate with either one or two active power supply modules or with power supplied by an XPS-2200. A Catalyst 3750-X switch that is in a StackPower stack can operate with power supplied by other switches in the stack. Table 1-1 and Table 1-2 show the power supply modules that ship with each switch model. All power supply modules (except the blank modules) have internal fans. All switches ship with a blank power supply module in the second power supply slot. Caution Do not operate the switch with one power supply module slot empty. For proper chassis cooling, both power supply module slots must be populated. The 350-W and 715-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1100-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The 440-W DC power supply module has dual input feeds (A and B) and supports input voltages between 36 and 72 VDC. The output voltage range is 51–57 V. Each AC power supply module has a power cord for connection to an AC power outlet. The 1100-W and 715-W modules use a 16-AWG cord (only North America). All other modules use an 18-AWG cord. The DC-power supply module must be wired to a DC-power source. The XPS-2200 powers connected switches when the power supply is removed or fails. When a new switch power supply is installed, the switch software polls the device. The switch power supply again provides power, and the XPS-2200 is available to power other devices. Table 1-16 shows the power supply modules available for Catalyst 3750-X and 3560-X switches and power supply configurations based on switch models.

Statement 387 The Cisco XPS-2200 is a expandable power system that can support nine network switches and provides power to one or two failed switches at a time. It senses when the power supply of a connected switch fails and provides power to the failed switch. Use the XPS-2200 only with approved Cisco XPS cables. You can order these XPS cables for connecting your switch to the XPS-2200 from your Cisco sales representative: • CAB-XPS-58CM (0.58-meter cable) • CAB-XPS-150CM (1.5-meter cable) The Cisco XPS-2200 has a nominal output level of –56 V. The total maximum output power depends on the installed power supply modules. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 1-19 Chapter 1 Product Overview Rear Panel Description The nine ports on the XPS-2200 provide the power and management signals to the Catalyst 3750-X and 3560-X switches. Other switch models do not support this management communication. The XPS-2200 communicates with each switch through the 12-pin cable. All connected switches can simultaneously communicate with the XPS-2200. You can configure these XPS-2200 features through the switch software: • Enable XPS active or standby mode for each connected switch • Configure switch priority for XPS support • List the connected switches and power supply module sizes • Report when a switch is powered by the XPS • Report the XPS power supply module status • Read and monitor backup, failure, and exception history See the switch software configuration guide on Cisco.com: http://www.cisco.com/en/US/products/ps10745/products_installation_and_ configuration_guides_list.html StackPower Connector (Catalyst 3750-X Switches) The Catalyst 3750-X switches have a StackPower connector for use with Cisco StackPower cables to configure a switch power stack that includes up to four switches. By adding an XPS-2200 expandable power system, you can configure a power stack that comprises up to nine switches. A switch power stack can be configured in redundant or power-sharing mode. You can order these StackPower cables from your Cisco sales representative: • CAB-SPWR-30CM (0.3-meter cable) • CAB-SPWR-150CM (1.5-meter cable) For details about connecting StackPower cables and StackPower guidelines, see the “Planning a StackPower Stack (Catalyst 3750-X Switches)” section on page 2-8. Management Ports Ethernet Management Port You can connect the switch to a host such as a Windows workstation or a terminal server through the 10/100 Ethernet management port or one of the console ports (see Figure 1-5 and Figure 1-6). The 10/100 Ethernet management port connection uses a RJ-45 crossover or straight-through cable. The RJ-45 console port connection uses the supplied RJ-45-to-DB-9 female cable. The USB console port uses a USB type-A-to-USB 5-pin mini-Type B cable. Table 1-19 shows the Ethernet management port LED colors and their meanings. Table 1-19 RJ-45 Console Port LED Color Description Green Active link to PC Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 1-20 OL-19593-01 Chapter 1 Product Overview Management Options Table 1-19 RJ-45 Console Port LED Color Description Off Inactive link Amber POST failure USB Mini-Type B Port The switch provides a USB mini-Type B console connection on the front panel, and the RJ-45 console port on the switch rear panel. Console output is always active on both connectors, but console input is active on only one connector at a time, with the USB connector taking precedence over the RJ-45 connector. Use a USB type-A-to-USB 5-pin mini-Type B cable to connect a PC or other device to the switch. The required USB cable is included in the optional accessory kit, (part number 800-33434). The connected device must include a terminal emulation application. Windows PCs need a driver for the USB port. See the “Installing the Cisco Microsoft Windows USB Device Driver” section on page C-3 for installation instructions. When the switch detects a valid USB connection to a powered device, input from the Ethernet connection is immediately disabled, and input from the USB console is enabled. Removing the USB connection immediately reenables input from the Ethernet connection. An LED on the switch front panel (see Figure 1-2) is green when the USB console connection is enabled. The switch provides a configurable inactivity timeout that reactivates the RJ-45 console if no input activity has occurred on the USB console for a specified time period. After the USB console has been deactivated due to a timeout, you can restore its operation by disconnecting and reconnecting the USB cable. You can disable USB console operation by using Cisco IOS commands. See the switch software configuration guide for details.

Note The grounding architecture of this product is DC-isolated (DC-I) 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 SFP or SFP+ module minimum bend radius and connector length is met. See the SFP or SFP+ module documentation for more information. • For switches with the optional 1100-W power-supply module (C3KX-PWR-1100WAC=), first rack-mount the switch before installing the power-supply module. • Make sure power-supply modules and fan modules are securely inserted in the chassis before moving the switch. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 2-3 Chapter 2 Switch Installation Planning a Switch Data Stack (Catalyst 3750-X Switches) • When connecting or disconnecting the power cord on a switch that is installed above or below a 1100-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 SFP+ 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 minimum 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 (only with the DC power supply) – National Electrical Manufacturers Association (NEMA) Type 1 – International Electrotechnical Commission (IEC) IP-20 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 Data Stack (Catalyst 3750-X Switches) Catalyst 3750-X switches can share bandwidth by using data stacking. • Switch Data Stacking Guidelines, page 2-5 • Data Stack Cabling Configurations, page 2-5 • Data Stack Bandwidth and Partitioning Examples, page 2-7 • Installing the Switch, page 2-14 Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 2-4 OL-19593-01 Chapter 2 Switch Installation Data Stack Cabling Configurations Switch Data Stacking Guidelines For general concepts and management procedures for switch stacks, see the switch software configuration guide on Cisco.com. When adding a Catalyst 3750-X switch to a Catalyst 3750 switch stack, review the Catalyst 3750-X 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 1100-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 1-16. The “Data Stack Cabling Configurations” section on page 2-5 provides examples of recommended configurations. • For rack-mounted switch stacks connected to the XPS-2200, review this recommended sequence of events: – If you are using the XPS-2200, install the XPS first at the bottom of the stack. If needed, allow one RU space between the XPS and the first switch above to provide room for cabling. – Connect the 12-pin XPS cables to the XPS-2200. – Rack-mount the switches. If you have the optional 1100-W power-supply module, first mount the switch before installing the power-supply module. – Connect the XPS cable to the first switch above the XPS-2200. Connect the stack cables to the first switch above the XPS. – Connect the XPS cable to the second switch above the XPS-2200. Connect the stack cables to the next switch above the XPS. – Repeat until all switches are connected. • For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see the “Planning a StackPower Stack (Catalyst 3750-X Switches)” section on page 2-8. Data Stack Cabling Configurations 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.

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 1 minute. These switches participate in the stack master election. Switches powered on after 1 minute 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. Planning a StackPower Stack (Catalyst 3750-X Switches) Catalyst 3750-X switches can share power by using the StackPower feature. • StackPower Stacking Guidelines, page 2-8 • StackPower Cabling Configurations, page 2-9 • Installing the Switch, page 2-14 StackPower Stacking Guidelines You can configure a StackPower stack for either power sharing or redundancy. In power-sharing mode, the power of all the power supplies in the stack is aggregated and distributed among the stack members. In redundant mode, when the total power budget of the stack is calculated, the wattage of the largest power supply is not included. That power is held in reserve and used to maintain power to switches and attached devices when one power supply fails. Following the failure of a power supply, the StackPower mode becomes power sharing. Note Power-sharing mode is the recommended configuration for Catalyst 3750-X switches. The Catalyst 3560-X switches support only redundant mode. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 2-8 OL-19593-01 Chapter 2 Switch Installation StackPower Cabling Configurations For general concepts and management procedures for switch power stacks, see the switch software configuration guide on Cisco.com. Before connecting the switches in a power stack, keep in mind these guidelines: • A switch power stack can include a maximum of four switches in a ring topology and nine switches in a star topology with the XPS-2200. • Size of the switch and any optional power supply module. The 1100-W power-supply module is 1.5 inches longer than the other modules, and with the attached cable retention clip, it extends 3 inches from the switch chassis. 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 StackPower cable, the 0.3 meter cable is supplied. If you need the 1.5 meter cable, you can order it from your Cisco supplier. For cable part numbers, see the “StackPower Connector (Catalyst 3750-X Switches)” section on page 1-20. The “StackPower Cabling Configurations” section on page 2-9 provides examples of recommended configurations. • For rack-mounted switch stacks that are members of a data stack and a StackPower stack, see the “Switch Data Stacking Guidelines” section on page 2-5. • For rack-mounted switch stacks connected to the XPS-2200, review this recommended sequence of events: – If you are using the XPS-2200, first install the XPS at the bottom of the stack. If needed, allow one RU space between the XPS and the first switch above to provide room for cabling. – Connect all the 12-pin XPS cables to the XPS-2200 as needed. – Rack-mount the switches. If you have the optional 1100-W power-supply module, first rack-mount the switch before installing the power-supply module. – Connect the XPS cable to the first switch above the XPS-2200. Connect the stack cables to the first switch above the XPS. – Connect the XPS cable to the second switch above the XPS-2200. Connect the stack cables to the second switch above the XPS. – Repeat until all devices are connected. StackPower Cabling Configurations This section describes the recommended cabling configurations for a StackPower stack. There are two types of StackPower cables. The cable in Figure 2-8 connects a Catalyst 3750-X switch to another 3750-X switch in a power stack or to an XPS-2200. The cable in Figure 2-9 connects a Catalyst 3750-X or 3560-X switch to an XPS-2200. Note All cable connectors are keyed and color-coded, as are the connections on the switches (See Figure 1-6 and Figure 1-7 on page 1-15). Both cable types are available in two lengths.

Installing a Network Module in the Switch These sections describe how to install and remove 1-Gigabit Ethernet and 10-Gigabit Ethernet network modules that provide uplink ports for the switch or the blank module, which provides no uplink ports. See the “Network Modules” section on page 1-4. Note There must be a supported network module in the network module slot. If no uplink ports are required, insert a blank network module. An empty slot generates error messages. The network module is hot-swappable. If you remove a module, replace it with another network module. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 2-23 Chapter 2 Switch Installation Installing a Network Module in the Switch Use only Cisco network modules and SFP or SFP+ modules with the switch. For information about supported SFP modules, see the “SFP and SFP+ Modules” section on page 1-5. For more information about installing, removing, cabling, and troubleshooting network modules, see the module documentation on Cisco.com. For module cable specifications, see Appendix B, “Connector and Cable Specifications.” Tools and Equipment You need to supply a number-2 Phillips screwdriver. Installing Network Modules When installing network modules, observe these general precautions: • Do not remove the EMC plug from the 10-Gigabit Ethernet slot until you are ready to install an SFP or SFP+ module. Either a module or a dust plug must be installed in the slot at all times. • Do not remove the dust plugs from the fiber-optic 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 a network module can shorten its useful life. Do not remove and insert any network module more often than necessary. • To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices. 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 Position the module face up to install in the module slot. See Figure 2-25. Slide the module into the opening until the back of the module faceplate is flush with the switch faceplate. Fasten the captive screws to secure the network module in place. Caution Do not insert or remove a network module with attached fiber-optic cables. A module interface might change to an error-disabled state when a network module is inserted or removed with connected fiber-optic cables. 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.

Connecting Devices to the Ethernet Ports Caution • 10/100/1000 Ethernet Port Connections, page 2-28 • PoE+ Port Connections, page 2-28 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. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 2-27 Chapter 2 Switch Installation Connecting Devices to the Ethernet Ports 10/100/1000 Ethernet Port Connections The 10/100/1000 Ethernet ports use 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 Table 2-3 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. Table 2-3 Recommended Ethernet Cables (When Auto-MDIX is Disabled) Device Crossover Cable1 Straight-Through Cable1 Switch to switch Yes No Switch to hub Yes No Switch to computer or server No Yes Switch to router No Yes Switch to IP phone No Yes 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 2-28. These ports can provide PoE or PoE+ inline power. PoE inline power supports devices compliant with the IEEE 802.3af standard, as well as prestandard Cisco IP Phones and Cisco Aironet Access Points. Each port can deliver up to 15.4 W of PoE. PoE+ inline power supports devices compliant with the IEEE 802.3at standard, by delivering up to 30 W of PoE+ power per port to all switch ports. See Table 1-17 on page 1-18 for the power supply modules required to support PoE and PoE+ on 24- and 48-port switches. To access a PoE planning tool, use the Cisco Power Calculator available on Cisco.com: http://tools.cisco.com/cpc/launch.jsp Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 2-28 OL-19593-01 Chapter 2 Switch Installation Where to Go Next You can use this application to calculate the power supply requirements for a specific PoE configuration. Enter the number and types of powered devices that you plan to attach to the switch, and the calculator shows the PoE or PoE+ power required and the system power consumption. 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: 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 1-17 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. Caution PoE faults are caused when noncompliant cabling or powered devices are connected to a PoE port. Use only standard-compliant cabling to connect Cisco prestandard IP Phones, 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. Warning Voice over IP (VoIP) service and the emergency calling service do not function if power fails or is disrupted. After power is restored, you might have to reset or reconfigure equipment to regain access to VoIP and the emergency calling service. In the USA, this emergency number is 911. You need to be aware of the emergency number in your country. Statement 361 Warning Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if interconnections are made using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods, unless the exposed metal parts are located within a restricted access location and users and service people who are authorized within the restricted access location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key or other means of security. Statement 1072 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. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 2-29 Chapter 2 Switch Installation Where to Go Next • 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.

A Catalyst 3750-X switch that is part of a StackPower stack operates with power supplied by other stack switches. You can use two AC modules, two DC modules, one AC and one DC module, or one module and a blank cover. All power supply modules have internal fans. All switches ship with a blank cover in the second power supply slot. The XPS-2200 operates in two modes: • In StackPower mode, it supplies power to the switches in the power stack (only Catalyst 3750-X switches with IP Base image). • In expandable power supply mode, it supplies power to a switch when the switch power supply is removed or fails. When you install or replace a power supply module, the switch software polls the device. After polling, the power supply module provides power to the switch, and the XPS-2200 is available to power other devices. Table 3-1 describes the supported internal power supply modules.

Observe these guidelines when removing or installing a power supply or fan module: • Do not force the power supply or fan module into the slot. This can damage the pins on the switch if they are not aligned with the module. • A power supply or fan module that is only partially connected to the switch can disrupt the system operation. • Remove power from the power-supply module before removing or installing the module. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 3-5 Chapter 3 Power Supply and Fan Module Installation Installing an AC Power Supply • You can remove and replace the power supply when the switch is connected to an XPS-2200 without interrupting normal switch operation. After a delay of about 3 seconds, the switch power supply automatically provides power, and the XPS-2200 is available to power other devices. Caution Do not operate the switch with one power-supply module slot empty. For proper chassis cooling, both module slots must be populated, with either a power supply or a blank module. Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029 • The switch supports hot swapping of a fan module. When replacing a fan, you should complete the replacement procedure within 5 minutes to avoid overheating the switch. • The switch continues to operate when there is one failed chassis cooling fan. If one fan fails, the switch sends an error message. If a second fan fails, the switch sends an error message, writes a failure log to flash memory, and shuts down. • Make sure that all power supply and fan modules are securely seated before moving the switch. • When replacing the 1100-W or 715-W power supply, verify that you are using the correct power cord (CAB-16AWG-AC, only in North America). Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206 Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from the device manager, the CLI, or an SNMP workstation. See the software configuration guide, the switch command reference guide on Cisco.com, or the documentation that came with your SNMP application for details. Switch POST Results As the switch powers on, it begins the power-on self-test (POST), a series of tests that runs automatically to ensure that the switch functions properly. It might take several minutes for the switch to complete POST. When the switch begins POST, the Status LED turns green. The System LED blinks green, and the other LEDs stay green. When POST completes successfully, the System LED remains green. The XPS LED is green for some time and then returns to its operating status. The other LEDs turn off and return to their operating status. If the switch fails POST, the System and Ethernet management port LEDs turn amber. Note POST failures are usually fatal. Contact your Cisco technical support representative if your switch does not pass POST. Switch LEDs Look at the port LEDs for information when troubleshooting the switch. See the “LEDs” section on page 1-8 for descriptions of the LED colors and their meanings. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 4-1 Chapter 4 Troubleshooting Diagnosing Problems Switch Connections Bad or Damaged Cable Always examine the cable for marginal damage or failure. A cable might be just good enough to connect at the physical layer, but it could corrupt packets as a result of subtle damage to the wiring or connectors. You can identify this situation because the port has many packet errors or the port constantly flaps (loses and regains link). • Exchange the copper or fiber-optic cable with a known good cable. • Look for broken or missing pins on cable connectors. • Rule out any bad patch panel connections or media convertors between the source and destination. If possible, bypass the patch panel or eliminate media convertors (fiber-optic-to-copper). • Try the cable in another port to see if the problem follows the cable. • Catalyst 3750-X switch StackWise cable: remove and inspect the cable and StackWise port for bent pins or damaged connectors. If the StackWise cable is bad, replace it with a known good cable. Ethernet and Fiber Cables Make sure that you have the correct cable: • For Ethernet, use Category 3 copper cable for 10 Mbps UTP connections. Use either Category 5, Category 5e, or Category 6 UTP for 10/100 or 10/100/1000 Mbps connections. • Verify that you have the correct fiber-optic cable for the distance and port type. Make sure that the connected device ports match and use the same type encoding, optical frequency, and fiber type. For more information about cabling, see the “SFP and SFP+ Module Cable Specifications” section on page B-5. • Determine if a copper crossover cable was used when a straight-through was required, or the reverse. Enable auto-MDIX on the switch, or replace the cable. See Table 2-3 for recommended Ethernet cables. Link Status Verify that both sides have link. A broken wire or a shut down port can cause one side to show link even though the other side does not have link. A port LED that is on does not guarantee that the cable is functional. It might have encountered physical stress, causing it to function at a marginal level. If the port LED does not turn on: • Connect the cable from the switch to a known good device. • Make sure that both ends of the cable are connected to the correct ports. • Verify that both devices have power. • Verify that you are using the correct cable type. See Appendix B, “Connector and Cable Specifications” for more information. • Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable and then reconnect it. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 4-2 OL-19593-01 Chapter 4 Troubleshooting Diagnosing Problems 10/100/1000 Port Connections A port appears to malfunction: • Verify the status of all ports. See Table 1-8 on page 1-10 for descriptions of the LEDs and their meanings. • Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or shut down. Re-enable the port if necessary. • Verify the cable type. See Appendix B, “Connector and Cable Specifications.” PoE Port Connections A powered device connected to a PoE port does not receive power: Caution Note • Verify the status of all ports. See Table 1-9 and Table 1-13 for descriptions of the LEDs and their meanings. • Use the show interfaces privileged EXEC command to see if the port is error-disabled, disabled, or shut down. Re-enable the port if necessary. • Verify that the power supply installed in the switch meets the power requirements of your connected devices. See the “Power Supply Modules” section on page 1-17 for more information. • Verify the cable type. 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 switch by a crossover cable. Replace the crossover cable with a straight-through cable. Noncompliant cabling or powered devices can cause a PoE port fault. Use only compliant cabling to connect Cisco prestandard IP phones, wireless access points, or IEEE 802.3af-compliant devices. The output of the PoE circuit has been evaluated as a limited power source (LPS) per IEC 60950. SFP Modules Use only Cisco network modules and SFP modules. • Inspect the network module and SFP module. Exchange the suspect module with a known good module. • Verify that the module is supported on this platform. (The switch release notes on Cisco.com list the SFP and SFP+ modules that the switch supports.) • Use the show interfaces privileged EXEC command to see if the port or module is error-disabled, disabled, or shut down. Re-enable the port if needed. • Make sure that all fiber connections are clean and securely connected. • For CX1 module connections, make sure that cable routing does not violate the minimum allowed cable bend radius. See the module documentation for specific cabling requirements. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 4-3 Chapter 4 Troubleshooting Diagnosing Problems Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher. • For long wave SFP+ modules, a mode conditioning patch might improve performance over maximum link distances with MMF connections. Interface Settings Verify that the port or interface is not disabled or powered off. If a port or interface is manually shut down on either side of the link, it does not come up until you re-enable the interface. Use the show interfaces privileged EXEC command to see if the interface is error-disabled, disabled, or shut down on either side of the connection. If needed, re-enable the interface. Ping End Device Ping from the directly connected switch first, and then work your way back port by port, interface by interface, trunk by trunk, until you find the source of the connectivity issue. Make sure that each switch can identify the end device MAC address in its Content-Addressable Memory (CAM) table. Spanning Tree Loops STP loops can cause serious performance issues that look like port or interface problems. A unidirectional link can cause loops. It occurs when the traffic sent by the switch is received by the neighbor, but the traffic from the neighbor is not received by the switch. A broken cable, other cabling problems, or a port issue could cause this one-way communication. You can enable UniDirectional Link Detection (UDLD) on the switch to help identify unidirectional link problems. For information about enabling UDLD on the switch, see the “Understanding UDLD” section in the software configuration guide on Cisco.com. Switch Performance Speed, Duplex, and Autonegotiation Port statistics that show a large amount of alignment errors, frame check sequence (FCS), or late-collisions errors, might mean a speed or duplex mismatch. A common issue occurs when duplex and speed settings are mismatched between two switches, between a switch and a router, or between the switch and a workstation or server. Mismatches can happen when manually setting the speed and duplex or from autonegotiation issues between the two devices. To maximize switch performance and to ensure a link, follow one of these guidelines when changing the duplex or the speed settings: • Let both ports autonegotiate both speed and duplex. • Manually set the speed and duplex parameters for the interfaces on both ends of the connection. • If a remote device does not autonegotiate, use the same duplex settings on the two ports. The speed parameter adjusts itself even if the connected port does not autonegotiate. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide 4-4 OL-19593-01 Chapter 4 Troubleshooting Resetting the Switch to the Factory Default Settings Autonegotiation and Network Interface Cards Problems sometimes occur between the switch and third-party network interface cards (NICs). By default, the switch ports and interfaces autonegotiate.Laptops or other devices are commonly set to autonegotiate, yet sometimes issues occur. To troubleshoot autonegotiation problems, try manually setting both sides of the connection. If this does not solve the problem, there could be a problem with the firmware or software on the NIC. You can resolve this by upgrading the NIC driver to the latest version. Cabling Distance If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable distance from the switch to the connected device meets the recommended guidelines. See the “Cable and Adapter Specifications” section on page B-5. Resetting the Switch to the Factory Default Settings If you have configured a new switch with a wrong IP address, or if all of the switch LEDs start blinking when you try to enter Express Setup mode, you can clear the IP address that is configured on the switch. Note Resetting the switch deletes the configuration and reboots the switch. To reset the switch: 1. Press and hold the Mode button (Figure 1-1 on page 1-3). The switch LEDs begin blinking after about 2 seconds. If the LEDs above the mode button turn solid green, you can release the Mode button and run Express Setup to configure the switch. If the LEDs do not turn solid green, continue with the next step. 2. Continue holding down the Mode button. The LEDs stop blinking after an additional 8 seconds, and then the switch reboots. The switch now behaves like an unconfigured switch. You can configure the switch by using Express Setup as described in the switch getting started guide on Cisco.com. You can also configure the switch by using the CLI setup procedure. See Appendix C, “Configuring the Switch with the CLI-Based Setup Program.” Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 4-5 Chapter 4 Troubleshooting Finding the Switch Serial Number Finding the Switch Serial Number If you contact Cisco Technical Assistance, you need to know the switch serial number. Figure 4-1 shows the serial number location. You can also use the show version privileged EXEC command to see the switch serial number.

The replacement switch must be a Catalyst 3750-X switch. 2. Power down the failed switch. Remove AC or DC input power, and if the switch is part of a StackPower stack, remove the StackPower cables. 3. Make sure the replacement switch is powered off, and then connect it to the stack. If you had manually set the member numbers for the switch stack, manually assign the member number of the failed switch to the replacement switch. To manually assign the stack member number, see the switch software configuration guide on Cisco.com. 4. Make the same Gigabit Ethernet connections on the replacement switch that were on the failed switch. 5. Reinstall any modules and cable connections. 6. Power on the replacement switch. The replacement switch will have the same configuration for all the interfaces as the failed switch and will function the same as the failed switch.

To set up the switch by using Express Setup, see the Cisco 3750-X and 3560-X Switch Getting Started Guide. Before connecting the switch to a power source, review the safety warnings in Chapter 2, “Switch Installation.” Accessing the CLI Accessing the CLI Through Express Setup You can access the CLI on an unconfigured switch by placing the switch in Express Setup mode and then connecting a switch Ethernet port or the Ethernet management port to the Ethernet port of your PC or workstation. To put the switch into Express Setup mode, follow the steps described in the getting started guide for powering on the switch and using Express Setup. When the switch is in Express Setup mode, open a Telnet session to the switch by entering the IP address 10.0.0.1. Enter the setup user EXEC command. Enter the information described in the “Entering the Initial Configuration Information” section on page C-6. After you have entered the configuration information for the switch, save it to flash memory by using the write memory privileged EXEC command. Note While in Express Setup mode, the IP address 10.0.0.1 remains active on the switch until you enter the write memory command. You lose the Telnet connection after entering the write memory command. For more information about using the CLI, see the command reference for this release. Accessing the CLI Through a Console Port You can enter Cisco IOS commands and parameters through the CLI. Catalyst 3750-X and 3560-X Switch Hardware Installation Guide OL-19593-01 C-1 Appendix C Configuring the Switch with the CLI-Based Setup Program Accessing the CLI Note If you have stacked Catalyst 3750-X switches, connect to the 10/100 Ethernet management port or console port of one of the stack switches. You can perform the initial configuration for the entire stack on any switch in the stack. Use one of these options to access the CLI: • RJ-45 Console Port • USB Console Port RJ-45 Console Port The RJ-45 console port is on the rear panel of the switch. Step 1 Connect the RJ-45-to-DB-9 adapter cable to the 9-pin serial port on the PC. Connect the other end of the cable to the switch console port.
