4.1PWR (Power)

•On (Green) - Indicates that the EMC39-12 is receiving power.

•Off - Indicates that the unit is not receiving power. Check the input power source (circuit breakers, fuse, power cord, etc.). If the proper source is present, the problem could be with the unit.

4.2XMT (Transmit)

•On (Flashing Green) - Indicates that the unit is transmitting data packets from the twisted pair port to the ﬁber optic port. The ﬂash of the LED is pulse stretched for viewing effect. The LED could be on solid because of this viewing effect.

•Off - No activity
