1075BSetting the MDI mode of an Ethernet interface
IMPORTANT:
Fiber ports do not support the MDI mode setting.
You can use both crossover and straight-through Ethernet cables to connect copper Ethernet interfaces.
To accommodate these types of cables, a copper Ethernet interface can operate in one of the following
Medium Dependent Interface (MDI) modes:
• Across mode
• Normal mode
• Auto mode
A copper Ethernet interface uses an RJ-45 connector, which comprises eight pins, each of which plays a
dedicated role. For example, pins 1 and 2 transmit signals, and pins 3 and 6 receive signals. The pin
role varies by the MDI modes as follows:
• In normal mode, pins 1 and 2 are transmit pins, and pins 3 and 6 are receive pins.
• In across mode, pins 1 and 2 are receive pins, and pins 3 and 6 are transmit pins.
• In auto mode, the interface negotiates pin roles with its peer.
To enable the interface to communicate with its peer, make sure its transmit pins are connected to the
remote receive pins. If the interface can detect the connection cable type, set the interface in auto MDI
mode. If not, set its MDI mode by using the following guidelines:
• When a straight-through cable is used, set the interface to operate in the MDI mode different than
its peer.
