Taking Out What You Need
Remove the items shown in Figure D-1 from the shipping container:
Figure D-1 The Catalyst 3750 Switch, Adapter Cable, AC Power Cord, and the StackWise Cable
Note For a DC switch, you will have a DC power supply terminal block.
You need to provide the Category 5 or later straight-through cables to connect the switch ports to other
Ethernet devices.
You can use the mdix auto interface configuration command in the CLI to enable the automatic
medium-dependent interface crossover (auto-MDIX) feature. When the auto-MDIX feature is enabled,
the switch detects the required cable type for copper Ethernet connections and configures the interfaces
accordingly. Therefore, you can use either a crossover or a straight-through cable for connections to a
copper 10/100, 10/100/1000, or 1000BASE-T SFP module port on the switch, regardless of the type of
device on the other end of the connection.
The auto-MDIX feature is enabled by default on switches running Cisco IOS Release 12.2(18)SE or
later. For releases between Cisco IOS Release 12.1(14)EA1 and 12.2(18)SE, the auto-MDIX feature is
disabled by default. For configuration information for this feature, see the switch software configuration
guide or the switch command reference.
