2Set the Switches

MDI-IIto MDI-XSwitch (twisted-pair port only)

To eliminate the need for crossover cables, the Access Optical Network Unit has an MDI-IIto MDI-Xswitch on its twisted-pair port. The switch is located on the front panel, to the right of the RJ-45 connector. Use this switch to configure the port for either a straight-through or crossover connection.

•The parallel symbol (II) indicates a straight-through or parallel connection. The switch is up. (default)

•The cross symbol (X) indicates a crossover connection. The switch is down.

Use the following table as a guide.

A device that is wired straight through needs one crossover connection:

If the cable is	the MDI-II to MDI-X switch setting should be
straight through	X
crossover	II

A device that is wired crossover needs a parallel connection:

If the cable is	the MDI-II to MDI-X switch setting should be
straight through	II
crossover	X
