Appendix D Configuring the Switch with the CLI-Based Setup Program Taking Out What You Need 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 1 SYST RPS MASTR STAT DUPLX SPEED STACK MODE 12 1X 34 56 78 9 10 11 12 11X 2X 12X 13 14 13X 15 16 17 18 19 20 21 22 23 24 23X 14X 24X Catalyst 3750 SERIES 2 3 90533 4 1 Catalyst 3750 switch 3 AC power cord 2 RJ-45-to-DB-9 adapter cable 4 StackWise cable (optional) 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. OL-6336-09 Catalyst 3750 Switch Hardware Installation Guide D-3

Configuring the Switch with the CLI-Based Setup Program
Taking Out What You Need
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
