Status LEDs

The green Status 1 LED illuminates when the CPU detects the presence of the distant CPU. When the CPU is operating, this LED normally illuminates when the near and far CPUs are active.

The green Status 2 LED illuminates when the CPU detects the presence of data passing through the wireless link. During normal CPU operation, this LED flickers when near and far CPUs are active.

MDI/MDI-X Switch

Interconnection on a 10BaseT Network must always be between MDI to MDI-X. The transmitter of each device must connect to the receiver of the other device. The reversal of the transmitter and receive assignments is called a crossover function. Every 10BaseT interconnection requires a crossover function. Generally, 10BaseT ports on an adapter card are configured as MDI, and 10BaseT ports on a repeater/hub are configured as MDI-X.

The CPU allows you to configure its 10BaseT port as an MDI (switch out position) or MDI-X (switch in position) port. The abbreviation MDI stands for Media Dependent Interface, and is specified by the IEEE 802.3i 10BaseT standard to be the electrical and mechanical interface to the UTP wire. An MDI port transmits out to the UTP wire on pins 1 and 2, and receives from the UTP wire on RJ-45 pins 3 and 6.

The MDI/MDI-X switch swaps the pin assignments of transmit and receive data wire pairs for the 10BaseT port. MDI-X configuration is used when the remote end of the wire is connected to a network station (for example, a10BaseT adapter card) or to an MDI port on a 10BaseT concentrator. MDI configuration is used when the remote end of the wire is connected to a 10BaseT concentrator.
