Cisco Systems ME3600X24CXM Manual De Usuario

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 

 for descriptions of the Ethernet management port LEDs. See 

the 

 for pinout information.

For console port and adapter pinout information, see the 

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.

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.
