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.
USB Mini-Type B Port
253163
Figure 1-3
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.

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.

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

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.

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:
Note
•
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.
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.

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:

Chapter 2
Switch Installation
Planning a Switch Data Stack
•
If two operating partial ring stacks are connected together using a stack cable, a stack merge can
occur. This situation reloads the whole stack (all switches in the 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:
– More than one running switch is removed without powering down.
– More than one stack cable is removed without powering down.
•
A stack split can occur in a partial ring stack if:
– A switch is removed without powering down.
– A stack cable is removed without powering down.
•
Note
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.
These results depend on how the switches are connected. You can remove two or more switches
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.
•
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.

Installing the Switch
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
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
Step 1
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).
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.
Note
Step 4
Step 5
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.
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).
Connect the other end of the cable to the port on the other switch and finger-tighten the screws. Avoid
overtightening the screws.

•
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.

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.
Catalyst 3650 Switch Hardware Installation Guide
OL-29734-01

Chapter 2
Switch Installation
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 Table 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.
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

Where to Go Next
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 Network Assistant application, which is described in the Getting Started with Cisco
Network Assistant guide. Through this GUI, you can configure and monitor a switch cluster or an
individual switch.
•
Use the CLI to configure the switch as a member of a cluster or as an individual switch from the
console. See the switch command reference on Cisco.com for information on using the CLI with the
switch.
•
Use the Cisco Prime Infrastructure application.

Table 1-12 on page 1-18 (switch power supply requirements for PoE and PoE+)
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 has dual input feeds (A and
B) and supports input voltages between -36 and -72 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.

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
Caution
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.
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.

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.
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.

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.
•
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.
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 Table 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.
•
Look for loose connections. Sometimes a cable appears to be seated but is not. Disconnect the cable
and then reconnect it.

Troubleshooting
Diagnosing Problems
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:
Caution
Note
•
Verify the status of all ports. See Table 1-3 and Table 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.
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 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.
Catalyst 3650 Switch Hardware Installation Guide
OL-29734-01
5-3
Chapter 5
Troubleshooting
Diagnosing Problems
•
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 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
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.

OL-29734-01
Chapter 5
Troubleshooting
Resetting the Switch
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.

Configuring the Switch with the CLI-Based
Setup Program
This appendix provides a CLI-based setup procedure for a Catalyst 3650 standalone switch or a switch
stack. To set up the switch by using Express Setup, see the Catalyst 3650 Switch Getting Started Guide.
Before connecting the switch to a power source, review the safety warnings in Chapter 2, “Switch
Installation.”
•

•
Entering the Initial Configuration Information, page C-5
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 Catalyst 3650
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-5.
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.
