THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
•Turn the television or radio antenna until the interference stops.
•Move the equipment to one side or the other of the television or radio.
•Move the equipment farther away from the television or radio.
•Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

10/100/1000 Ethernet Ports
251960
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 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

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.

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.

For information about SFP modules, see your SFP module documentation and the “Installing SFP and SFP+ Modules” section on page 2-25. For cable specifications, see Appendix B, “Connector and Cable Specifications.”
Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher.
The Catalyst 3560-X switch supports the SFP module patch cable (CAB-SFP-50CM), a 0.5-meter, copper, passive cable with SFP module connectors at each end. This cable is only used with 1-Gigabit Ethernet SFP ports to connect two Catalyst 3560-X switches in a cascaded configuration.
LEDs
You can use the switch LEDs to monitor switch activity and its performance. Figure 1-2 shows the Catalyst 3750-X switch LEDs and the Mode button that you use to select a port mode.

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.

The stack LED shows the sequence of member switches in a stack. Up to nine switches can be members of a stack. The first nine port LEDs show the member number of a switch in a stack. Figure 1-3 shows the LEDs on the first switch, which is stack member number 1. For example, if you press the Mode button and select Stack, the LED for port 1 blinks green. The LEDs for ports 2 and 3 are solid green, as these represent the member numbers of other switches in the stack. The other port LEDs are off because there are no more members in the stack.

USB Type A Interface
The USB Type A interface provides access to external USB FLASH devices (also known as thumb drives or USB keys).
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)

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 24and 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.

Chapter 1 Product Overview
Rear Panel Description
For information about replacing a power supply module, wiring a DC power supply module, and module specifications, see Chapter 3, “Power Supply and Fan Module Installation,” and Appendix A, “Technical Specifications.”
Fan Modules
The switch has two internal hot-swappable 12-V fan modules, each with two fans. The air circulation system consists of the fan modules and the power supply modules. The airflow patterns vary depending on the power supply configuration.
Figure 1-8 shows the airflow patterns for the 24and 48-port switches. The blue arrow shows cool air flow, and the red arrow shows warm air flow. When the fan modules are operating properly, a green LED is on at the top left corner of the fan assembly (viewed from the rear). If the fan fails, the LED turns to amber.

XPS Connector
Warning Attach only the following Cisco external power system to the switch: XPS 2200. 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.

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.
