To eliminate the need for crossover cables, the Access Optical Network
Unit has an MDI-

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.
