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
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
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.

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).
Table 1-7 PoE+ Mode LED
Color PoE+ Status
Off PoE mode is not selected. None of the 10/100/1000 ports have been denied power
or are in a fault condition.
Green PoE mode is selected, and the port LEDs show the PoE+ status.
Blinking amber PoE mode is not selected. At least one of the 10/100/1000 ports has been denied
power, or at least one of the 10/100/1000 ports has a PoE+ fault.

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.

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