Cable and Adapter Specifications
Dual-Purpose Ports
The Ethernet port on a dual-purpose port uses standard RJ-45 connectors. Figure C-2 shows the pinouts.
The SFP transceiver slot on a dual-purpose port uses SFP modules for fiber-optic and copper uplink
ports. See the switch release notes for a list of supported SFP transceivers.
The auto-MDIX feature is enabled by default. For configuration information for this feature, see the
switch software configuration guide or the switch command reference.
Console Port
The console port uses an 8-pin RJ-45 connector, which is described in Table C-2 and Table C-2. The
supplied RJ-45-to-DB-9 adapter cable is used to connect the console port of the switch to a console PC.
You need to provide a RJ-45-to-DB-25 female DTE adapter if you want to connect the switch console
port to a terminal. You can order a kit (part number ACS-DSBUASYN=) containing that adapter from
Cisco. For console port and adapter pinout information, see Table C-2 and Table C-3.

SFP Transceiver Cable Specifications
Table C-1 lists the cable specifications for the rugged fiber-optic SFP transceiver connections. Each port
must match the wave-length specifications on the other end of the cable, and for reliable
communications, the cable must not exceed the required cable length. Copper 1000BASE-T SFP
transceivers use standard four twisted-pair, Category 5 or greater cable at lengths up to 328 feet
(100 meters).
