Connecting Devices
This section describes how to connect to the fixed switch module ports and to the 10-Gigabit Ethernet
module slot.
Connect to 10/100/1000 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 UTP cable. The 10BASE-T traffic can use Category 3 or Category 4 cable.
The autonegotiation feature is enabled by default on the switch module. At this setting, the switch
module 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 module port speed and the duplex
parameters. To maximize performance, either allow the ports to 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 on the switch module. With auto-MDIX enabled, the switch module detects the
required cable type for copper Ethernet connections and configures the interface accordingly.
Therefore, you can use either a crossover or a straight-through cable for connections to a switch
module 10/100/1000 Ethernet port, regardless of the type of device on the other end of the connection.
For more information about enabling or disabling autonegotiation and auto-MDIX, see the switch
module software configuration guide or the command reference on Cisco.com.
Install and Connect to Devices in the 10-Gigabit Ethernet Slot
The switch module 10-Gigabit Ethernet module slot is used for connections to other switches
and routers. The module slot operates in full-duplex mode and uses the hot-swappable Cisco X2
transceiver module. The X2 transceiver module has SC connectors to connect to multimode fiber
(MMF) and single-mode fiber (SMF) cables.
Use only Cisco X2 transceiver modules with the switch module. Each Cisco module has an internal
serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to
identify and validate that the module meets the requirements for the switch module.
