Management and Console Port
You can connect the switch to a host such as a Windows workstation or a terminal server through the
10/100/1000 Ethernet management port or the console port. The 10/100/1000 Ethernet management port
connection uses a standard RJ-45 crossover or straight-through Ethernet cable. The console port
connection uses a RJ-45-to-DB-9 female cable.
The Ethernet management port operates in any combination of 10, 100, or 1000 Mb/s, and its traffic is
isolated from the other ports. See

10/100/1000 Gigabit Ethernet Ports
The 10/100/1000 Ethernet ports use standard RJ-45 connectors with Ethernet pinouts. The maximum
cable length is 328 feet (100 meters). The 100BASE-TX and 1000BASE-T traffic requires Category 5,
Category 5e, or Category 6 unshielded twisted pair (UTP) cable. The 10BASE-T traffic can use
Category 3 or Category 4 UTP cable.
The autonegotiation feature is enabled by default. The switch ports configure themselves to operate at
the speed of attached devices. If the attached device does not support autonegotiation, you can explicitly
set the switch port speed and the duplex parameters. To maximize performance, either let the ports
autonegotiate both speed and duplex, or set the port speed and duplex parameters on both ends of the
connection.
For simplified cabling, the automatic medium-dependent interface crossover (auto-MDIX) feature is
enabled by default. The switch detects the required cable type for copper Ethernet connections and
configures the interface accordingly. You can use either a crossover or a straight-through cable for
connections to a switch 10/100/1000 Ethernet port, regardless of the type of device on the other end of
the connection.
SFP+ and SFP Modules
The switch 10-Gigabit Ethernet SFP+ modules are used for connections to other devices. These
transceiver modules are field-replaceable, providing the uplink interfaces when inserted in an SFP+
module slot. You can use any combination of SFP+ or SFP modules. The SFP+ modules have LC
connectors for fiber-optic connections. The SFP+ module slots support SFP+ and 1000BASE-X SFP
modules. The SFP+ module slots do not support 100BASE-X and 1000BASE-T modules.
Use only Cisco SFP+ or SFP modules on the switch. Each Cisco module has an internal serial EEPROM
that is encoded with security information.
