Connector and Cable Specifications

This appendix describes the Catalyst 3500 XL switch ports and the cables and
adapters that you use to connect the switch to other devices.

Connector Specifications

10/100 Ports

The 10/100 Ethernet ports use standard RJ-45 connectors and Ethernet pinouts
with internal crossovers, as indicated by an X in the port name. These ports have
their transmit (TD) and receive (RD) signals internally crossed so that a
straight-through cable and adapter can be attached to the port. Figure B-1 shows
the pinout.
When connecting the 10/100 ports to compatible workstations, servers, routers,
and Cisco IP Phones, you must use a straight-through cable wired for 10BaseT
and 100BaseTX (Figure B-5 illustrates the straight-through cable schematics).
When connecting to other switches or repeaters, ensure that you use a crossover
cable. (Figure B-4 illustrates the crossover cable schematics.)
Use a straight-through cable to connect two ports when one of the
Note
ports is designated with an X. Use a crossover cable to connect two
ports when both ports are designated with an X or when both ports
do not have an X.
