                      SIGNAL QUALITY ERROR (SQE) TEST

                 Setting                                JP1

  »                Disabled                            Closed

                   Enabled                              Open

  Note: Signal Quality Error (SQE) is a test of the collision circuitry
  and path.

                            LINK INTEGRITY TEST

                 Setting                                JP2

  »                Enabled                             Closed

                   Disabled                             Open

  Note: Link Integrity is only used with 10Base-T wiring. When using an
  AUI transceiver, the test should be disabled.
