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).

Chapter 1 Product Overview

• 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)

1-6

• 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

OL-29734-01

Chapter 1 Product Overview

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.

Front Panel

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

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.

253163

OL-29734-01

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.

Catalyst 3650 Switch Hardware Installation Guide

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

Chapter 1 Product Overview

LEDs

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.”

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. Tabl e 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. Ta b le 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.

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.

Chapter 1 Product Overview

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

Supported power supply modules:

• PWR-C2-250WAC=

• PWR-C2-640WAC=

Rear Panel

• 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.

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 24- and 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.

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.

Chapter 2 Switch Installation

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.

Chapter 2 Switch Installation

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 Tab l e 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.

Planning a Switch Data 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.

connections. This stack provides only half bandwidth and does not have redundant connections.

Figure 2-4 Example of a Data Stack with Half Bandwidth Connections

Figure 2-5 and Figure 2-6 show data stacks of Catalyst 3650 switches with failover conditions. In Figure 2-5, the StackWise cable is bad in link 2. Therefore, this stack provides only half bandwidth and

does not have redundant connections. In Figure 2-6, link 2 is bad. Therefore, this stack partitions into two stacks, and the top and bottom switches become the active switch in the stack. If the bottom switch is a member (not active or standby switch), it reloads.

Power-On Sequence for Switch Data 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

active switch and the standby switch.

• There are two ways to elect an active switch:

–

If you want a particular switch to become the active switch, configure it with the highest priority. Among switches with same priority, the switch with the lowest MAC address becomes the active switch.

–

If you want a particular switch to become the active switch, power on that switch first. This switch remains the active switch until a reelection is required. After 2 minutes, power on the other switches in the stack. If you have no preference as to which switch becomes the active switch, power on all the switches in the stack within 1 minute. These switches participate in the active switch election. Switches powered on after 2 minutes do not participate in the election.

If changes are made to the stack without powering down the switches, the following results can occur:

OL-29734-01

Planning a Switch Data Stack

• If some switches in the stack are completely separated from the stack, a stack split can occur.

• A stack split can occur on a full ring stack if:

• A stack split can occur in a partial ring stack if:

• In a split stack, depending on where the active and standby switches are located, either two stacks

might be formed (with the standby taking over as the new active switch in the newly formed stack) or all the members in the newly formed stack might reload.

from the stack without splitting the stack.

For conditions that can cause a stack reelection or to manually elect the active switch, see the stacking software configuration guide on Cisco.com at this URL:

http://www.cisco.com/go/cat3650_docs

Changes to Switch Stack Membership

If you replace a stack member with an identical model, the new switch functions with exactly the same configuration as the replaced switch, assuming that the new switch (referred to as the provisioned switch) is using the same member number as the replaced switch.

The operation of the switch stack continues uninterrupted during membership changes unless you remove the active switch or you add powered-on standalone switches or switch stacks.

Note A switch stack always has one active switch and one standby switch. The active switch contains the

saved and running configuration files for the switch stack. If the active switch becomes unavailable, the standby switch assumes the role of the active switch, and continues to the keep the stack operational.

For powered-on switches:

• Adding powered-on switches (merging) causes all switches to reload and elect a new active switch

from among themselves. The newly elected active switch retains its role and configuration. All other switches change their stack member numbers to the lowest available numbers and use the stack configuration of the newly elected active switch.

2-8

• Removing powered-on stack members causes the switch stack to divide (partition) into two or more

switch stacks, each with the same configuration. This can cause an IP address configuration conflict in your network. If you want the switch stacks to remain separate, change the IP address or addresses of the newly created switch stacks.

If a newly created switch stack does not have an active switch or standby switch, the switch stack will reload and elect a new active switch.

Catalyst 3650 Switch Hardware Installation Guide

OL-29734-01

Chapter 2 Switch Installation

Note Make sure that you power off the switches that you add to or remove from the switch stack.

After adding or removing stack members, make sure that the switch stack is operating at full bandwidth. Press the Mode button on a stack member until the Stack mode LED is on. The last two right port LEDs on all switches in the stack should be green. Depending on the switch model, the last two right ports are 10-Gigabit Ethernet ports or small form-factor pluggable (SFP) module ports (10/100/1000 ports). If one or both of these LEDs are not green on any of the switches, the stack is not operating at full bandwidth.

If you remove powered-on members but do not want to partition the stack:

• Power off the switches in the newly created switch stacks.

• Reconnect them to the original switch stack through their stack ports.

• Power on the switches.

Connecting to the StackWise Ports

Before connecting the StackWise cables, review the “Planning a Switch Data Stack” section on page 2-4. Always use a Cisco-approved StackWise cable to connect the switches.

Caution Removing and installing the StackWise cable can shorten its useful life. Do not remove and install the

cable more often than is absolutely necessary (removing and installing it up to 200 times is supported).

Step 1 Remove the dust covers from the StackWise cables and store them for future use.

A StackWise adapter must be installed in the StackWise port to enable stacking. The default setup is that StackWise adapter blanks are installed in the StackWise ports. If StackWise stacking is ordered with the switch, StackWise adapters are already installed in the StackWise ports, and you can proceed to step 4.

Step 2 Remove the StackWise adapter blanks from each destination StackWise port using the Torx T15 Allen

key provided in the stacking kit (or a Torx T15 screwdriver), as shown in Figure 2-11. Store them for future use.

Step 3 Install a StackWise adapter in each destination StackWise port, and secure in place using the supplied

Torx T15 key, or a Torx T15 screwdriver, as shown in Figure 2-12.

Connecting to the StackWise Ports

Note It is not necessary to remove the fan modules prior to removal or installation of the StackWise

adapter. If the installation is performed with the system powered-on, the fans must be left in the installed position at all times.

Step 4 Connect the StackWise cable to the StackWise port on the switch rear panel:

a. Align the StackWise cable connector with the StackWise adapter in the StackWise port.

b. Insert the StackWise cable connector in to the StackWise port as shown in Figure 2-13. Make sure

that the Cisco logo is on the top side of the connector.

c. Finger-tighten the screws (clockwise direction).

Step 5 Connect the other end of the cable to the port on the other switch and finger-tighten the screws. Avoid

overtightening the screws.

Statement 1008

• 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 necessary.

• To prevent ESD damage, follow your normal board and component handling procedures when

connecting cables to the switch and other devices.

Observe these precautions:

Step 1 Attach an ESD-preventive wrist strap to your wrist and to an earth ground surface.

Step 2 Find the send (TX) and receive (RX) markings that identify the top of the SFP module.

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

Step 3 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Step 4 Align the module in front of the slot opening, and push until you feel the connector snap into place.

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 you cannot use

your finger to open the latch, use a small, flat-blade screwdriver or other long, narrow instrument to open it.

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

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

Connecting Devices to the Ethernet Ports

• 10/100/1000 Ethernet Port Connections, page 2-19

• PoE+ Port Connections, page 2-21

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.

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.

OL-29734-01

Catalyst 3650 Switch Hardware Installation Guide

2-19

Connecting Devices to the Ethernet Ports

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 l e 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.

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 2-19. 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 1-12 on page 1-18 for the power supply modules required to support PoE and PoE+ on 24- and 48-port switches.

Straight-Through Cable

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.

Installation Guidelines

Table 3-1 lists the switches and the compatible 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 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.

• The power supply is hot-swappable. In some configurations, such as full PoE+ or power-sharing

mode, removing a power supply causes powered devices to shut down until the power budget matches the input power of a single power supply. To minimize network interruption, hot swap the power supply ensuring that the remaining supply has sufficient PoE power for all powered ports.

For the switch commands that display available power budget, see the software configuration guide.

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.

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 cover.

Installing the Fan

This chapter describes how to install a fan module.

• Overview, page 4-1

• Fan Module Installation, page 4-2

• Finding the Fan Module Serial Number, page 4-4

The switch has three fan modules. Fan modules are hot-swappable. A powered switch should always have more than one operational fan. The switch can operate with two operational fans and one nonfunctional fan, 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.

Diagnosing Problems

The switch LEDs provide troubleshooting information about the switch. They show POST failures, port-connectivity problems, and overall switch performance. You can also get statistics from 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.

CHA P T E R

Switch POST Results

Approximately 30 seconds after the switch powers on, it begins the power-on self-test (POST), which can take up to 5 minutes to complete. During POST, the SYSTEM LED blinks green. When POST is complete, the SYSTEM LED turns solid green, the ACTV LED is green if the switch is acting as the active switch.

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.

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.

• For Catalyst 3650 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.

Chapter 5 Troubleshooting

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 (100 meters or less) 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-7.

• 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 Tab le 2-1 for recommended Ethernet cables.

Link Status

Verify that both sides have a link. A broken wire or a shut-down port can cause one side to show a link even though the other side does not have a 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.

5-2

• Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable

and then reconnect it.

Catalyst 3650 Switch Hardware Installation Guide

OL-29734-01

Chapter 5 Troubleshooting

10/100/1000 Port Connections

A port appears to malfunction:

• Verify the status of all ports. See Table 1-3 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. Reenable the port if necessary.

• Verify the cable type. See Appendix B, “Connector and Cable Specifications.”

PoE and PoE+ Port Connections

A powered device connected to a PoE port does not receive power:

• Verify the status of all ports. See Tab l e 1-3 and Ta b l e 1-7 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. Reenable 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.

Diagnosing Problems

Caution Noncompliant cabling or powered devices can cause a PoE port fault. Use only compliant cabling to

SFP Modules

connect Cisco prestandard IP phones, wireless access points, or IEEE 802.3af-compliant devices.

Use only Cisco SFP modules.

• Inspect the uplink port 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. Reenable the port if needed.

• Make sure that all fiber connections are clean and securely connected.

• For CX1 module connections and fiber connections, make sure that cable routing does not violate

the minimum allowed cable bend radius. See the module documentation for specific cabling requirements.

Note When ordering or using CX1 cables, ensure that the version identifier is 2 or higher.

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 reenable 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, reenable 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

Chapter 5 Troubleshooting

maximum link distances with MMF connections.

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.

5-4

Catalyst 3650 Switch Hardware Installation Guide

OL-29734-01

Chapter 5 Troubleshooting

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

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 reboots the switch.

To reset the switch:

1. Press and hold the Mode button (Figure 1-1 on page 1-5).

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.

You can also configure the switch by using the CLI setup procedure. See Appendix C, “Configuring the

Switch with the CLI-Based Setup Program.”

Replacing a Failed Data Stack Member

To replace a failed data stack member:

1. The replacement switch must be a Catalyst 3650 switch.

2. Power down the failed switch. Remove AC or DC input power.

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.
