Connector and Cable Specifications
This appendix describes the Catalyst 3560 switch ports and the cables and
adapters that you use to connect the switch to other devices.
Connector Specifications
These sections describe the connectors used with the Catalyst 3560 switch.
10/100 Ports
The 10/100 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts
with internal crossovers. These ports have the transmit (TD) and receive (RD)
signals internally crossed so that a twisted-pair straight-through cable and adapter
can be attached to the port. Figure B-1 shows the pinout.
Caution PoE faults are caused when noncompliant cabling or powered devices are
connected to a PoE port. Only standard-compliant cabling can be used to connect
Cisco pre-standard IP Phones or 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.
