10/100/1000 Ethernet Ports

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 2-19 and Appendix B, “Connector and Cable Specifications.”

PoE and PoE+

The PoE+ ports use the same connectors as described in the “10/100/1000 Ethernet Ports” section on page 1-6.

These PoE+ ports provide:

•Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and support for IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port).

•Support for Cisco-enhanced PoE.

•Support for prestandard Cisco powered devices.

•Configurable support for Cisco intelligent power management, including enhanced power negotiation, power reservation, and per-port power policing.

See Table 1-12 on page 1-18 for the power supply matrix that defines the available PoE and PoE+ power per port.

Note For information on 250-W AC power supply support on the PoE-capable switch models, refer to the

Release Notes for the Cisco Catalyst 3650 Switch on Cisco.com.

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 2-21, and Appendix B, “Connector and Cable Specifications.”

Management Ports

•Ethernet management port (see the “Ethernet Management Port” section on page 1-20)

•RJ-45 console port (EIA/TIA-232) (see the “RJ-45 Console Port” section on page 1-20)

•USB mini-Type B console port (5-pin connector)

You can connect the switch to a host such as a Windows workstation or a terminal server through the Ethernet management port, the RJ-45 console port, or the USB console port (USB mini-Type B port).

The USB console port connection uses a USB Type A to 5-pin mini-Type B cable. The USB console interface speeds are the same as the RJ-45 console interface speeds.

Catalyst 3650 Switch Hardware Installation Guide

1-6	OL-29734-01

Chapter 1 Product Overview

Front Panel

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.

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 RJ-45 console port is immediately disabled, and input from the USB console is enabled. Removing the USB connection immediately reenables input from the RJ-45 console connection. An LED on the switch front panel (see Figure 1-4) 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 4-pin mini-Type B connectors resemble 5-pin mini-Type B connectors. They are not compatible. Use only the 5-pin mini-Type B. See Figure 1-3.

Figure 1-3 USB Mini-Type B Port

253163

You can use the command-line interface (CLI) to configure an inactivity timeout which reactivates the RJ-45 console if the USB console has been activated and no input activity has occurred on the USB console for a specified time period.

After the USB console deactivates due to inactivity, you cannot use the CLI to reactivate it. Disconnect and reconnect the USB cable to reactivate the USB console. For information on using the CLI to configure the USB console interface, see the switch software guide.

USB Type A Port

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 the ability to format the flash device with a FAT file system.

For more information about the switch management ports, see the switch software configuration guide and the command reference on Cisco.com and the “Connector Specifications” section on page B-1.

Chapter 1 Product Overview

Front Panel

Uplink Ports

The switch supports four SFP module slots that provide uplink ports to connect to other devices. Depending upon the switch model, the uplink port support for SFP and SFP+ modules is:

•Four slots supporting only 1-Gigabit SFP modules.

•Two slots (left side) supporting only 1-Gigabit SFP modules and two slots (right side) supporting either 10-Gigabit SFP+ modules or 1-Gigabit SFP modules.

•Four slots supporting either 1-Gigabit SFP modules or 10-Gigabit SFP+ modules.

For more information, see “Catalyst 3650 Switch Models” in Table 1-1 on page 1-1. For cable specifications, see Appendix B, “Connector and Cable Specifications.”

Note If you insert an SFP+ module in an SFP module slot, the SFP+ module slot does not operate, and the switch logs an error message. SFP modules can operate in SFP+ module slots.

SFP and SFP+ Modules

The SFP and SFP+ modules provide copper or fiber-optic connections to other devices. These transceiver modules are field replaceable, and provide 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 and SFP+ modules on the switch. For the latest information about supported SFP/SFP+ modules, refer to the Cisco Transceiver Modules Compatibility Matrix documentation at:

http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_support_tables_list.html

For information about SFP modules, see your SFP module documentation and the “Installing SFP and SFP+ Modules” section on page 2-17. For cable specifications, see Appendix B, “Connector and Cable Specifications.”

LEDs

You can use the switch LEDs to monitor switch activity and its performance. Figure 1-4 shows the switch LEDs and the Mode button that you use to select a port mode.

Port LEDs and Modes

Each Ethernet port, 1-Gigabit Ethernet module slot, 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 1-3 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 1-4 explains how to interpret the port LED colors in different port modes.

When you press the Mode button on any switch in the switch stack, all the stack switches change to show the same selected mode. For example, if you press the Mode button on the active switch to show the SPEED LED, all the other switches in the stack also show the SPEED LED.

STACK LED

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 1-5 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.

Uplink Ports LEDs

The four uplink ports have four status LEDs. Each port LED is labeled according to its SFP and SFP+ module status.

For SFP ports, a G(x) labeling nomenclature is used, where G = 1 Gigabit and x = the port number. The The G(x) label appears to the left of the uplink port LED.

For SFP+ ports, a TE(x) labeling nomenclature is used, where TE = 10 Gigabit and x = the port number. The TE(x) label appears to the right of the uplink port LED.

An SFP+ module ports has two labels, G(x) and TE(x), because it supports both SFP and SFP+ modules. The uplink port labeling layouts for the various switch models are:

•Four uplink port LEDs labeled G1, G2, G3, G4—This labeling represents four ports supporting SFP modules.

•Four uplink port LEDs labeled G1, G2, G3, G4 and two right side uplink ports LEDs also labeled TE3 and TE4—This labeling represents two ports (left side) supporting SFP modules and two ports (right side) supporting SFP and SFP+ modules.

•Four uplink port LEDs labeled G1, G2, G3, G4 and TE1, TE2, TE3, TE4—This labeling represents four slots supporting SFP and SFP+ modules.

Figure 1-6 shows an example of an uplink ports LED arrangement representing two SFP and two SFP+ ports (Catalyst 3650-48FD-S switch model).

StackWise Ports

StackWise ports are used to connect switches in StackWise stacking configurations. StackWise cables are used to connect the StackWise ports for stacking. For more information on StackWise cables, see the “StackWise Cables” section on page B-5.

A StackWise adapter must be installed in the StackWise port to enable stacking. StackWise adapter blanks installed in the StackWise ports is the default setup. For more information on StackWise adapters and StackWise adapter blanks, see the “StackWise Adapters” section on page B-6 and the “StackWise Adapter Blanks” section on page B-7.

	Catalyst 3650 Switch Hardware Installation Guide
1-16	OL-29734-01

Chapter 1 Product Overview

Rear Panel

For Catalyst 3650 switches where stacking is specified, StackWise adapters are preinstalled in the StackWise ports, and optional StackWise cables can be ordered. When stacking is not specified, but is required, the StackWise adapter blanks must be removed and StackWise adapters installed. For more information on connecting switches for stacking see “Connecting to the StackWise Ports” section on page 2-15.

Caution Use only approved cables, and connect only to similar Cisco equipment. Equipment might be damaged if connected to nonapproved Cisco cables or equipment.

Note You cannot have a switch stack containing a mix of Catalyst 3650 and Catalyst 3850 switches.

Power Supply Modules

The 24and 48-port switches are powered through one or two internal power supply modules.

Supported power supply modules:

•PWR-C2-250WAC=

•PWR-C2-640WAC=

•PWR-C2-1025WAC=

•PWR-C2-640WDC=

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 cover. The switch can operate with either one or two active power supply modules.

Table 1-1 shows the default power supply modules that ship with each switch model. All power supply modules (except the blank covers) have internal fans. All switches ship with a blank cover in the second power supply slot if switches are configured with only one power supply.

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, or with either a power supply or a blank cover.

The 250-W and 640-W AC power supply modules are autoranging units that support input voltages between 100 and 240 VAC. The 1025-W power supply module is an autoranging unit that supports input voltages between 115 and 240 VAC. The 640-W DC power supply module supports input voltages between -40 and -60 VDC.

Note For information on 250-W AC power supply support on the PoE-capable switch models, refer to the

Release Notes for the Cisco Catalyst 3650 Switch on Cisco.com.

Each AC power supply module has a power cord for connection to an AC power outlet. The 1025-W and 640-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.

Table 1-10, Table 1-11, and Table 1-12 show the PoE available and PoE requirements for Catalyst 3650 switches.

For information about replacing a power supply module, wiring a DC power supply module, and module specifications, see Chapter 3, “Power Supply Installation,” and Appendix A, “Technical Specifications.”

Fan Modules

The switch has three internal hot-swappable 12-V fan modules. 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. The switch can operate with two operational fans, but the failed fan should be replaced as soon as possible to avoid a service interruption due to a second fan fault.

Note Three fans are required for proper cooling.

Installation Guidelines

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

•For the clearance to the front and rear panels, make sure that

–Front-panel indicators can be easily read.

–Clearance is at least 4.4 in. (11.1 cm) from switch rear panel.

–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 1025-W power-supply module (PWR-C2-1025WAC=), 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.

•When connecting or disconnecting the power cord on a switch that is installed above or below a 1025-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 maximum cable length.

Catalyst 3650 Switch Hardware Installation Guide

	OL-29734-01	2-3

Chapter 2 Switch Installation

Planning a Switch Data Stack

•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.

Tools and Equipment

Obtain these necessary tools and equipment:

•A number-2 Phillips screwdriver to rack-mount the switch.

•A Torx T15 screwdriver, or the Torx T15 key that ships with StackWise upgrade kits, to install the StackWise adapter.

Verifying Switch Operation

Before you install the switch in a rack, or on a table or shelf, you should power on the switch and verify that the switch passes POST. See the “Running Express Setup” section in the getting started guide for the steps required to connect a PC to the switch and to run Express Setup.

Powering Off the Switch

After a successful POST, disconnect the power cord from the switch. Install the switch in a rack, on a table, or on a shelf as described in the Chapter 2, “Installing the Switch,” section.

Planning a Switch Data Stack

Catalyst 3650 switches can share bandwidth by using data stacking.

Chapter 2 Switch Installation

Planning a Switch Data Stack

Switch Stacking Guidelines

For general concepts and management procedures for switch stacks, see the switch software configuration guide on Cisco.com.

A StackWise adapter must be installed in the stacking port to enable stacking. The StackWise cable connects to the StackWise adapter in the stacking port. For switches ordered with stacking, the StackWise adapters are pre-installed. If the switch is not ordered with stacking, the adapters must be ordered separately and installed.

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

•Size of the switch and any optional power-supply module. The 1025-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 StackWise cable. Depending on the configurations that you have, you might need different-sized StackWise 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 Cables” section on page B-5. The “Data Stack Cabling Configurations” section on page 2-5 provides examples of recommended configurations.

•Minimum bend radius and coiled diameter for StackWise cables. Cisco recommends a minimum bend radius and coiled diameter for each StackWise cable. For more information, see Table B-1 in the “StackWise Cables Minimum Bend Radius and Coiled Diameter” section on page B-6.

•Data stacks can be created with up to nine switches in a stack.

Note You cannot have a switch stack containing a mix of Catalyst 3650 and Catalyst 3850 switches.

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.
