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 Category5, 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 page2-19 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 Table1-12 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 page1-17, 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 page1-20)
•RJ-45 console port (EIA/TIA-232) (see the “RJ-45 Console Port” section on page1-20)
•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.
