Figure 9: E-TBT-MC04 LEDs

The E-TBT-MC04 LEDs display the operational status of the transceiver. The following table explains LED indications.

LED	Description
Collision	Blinks when detects a collision
Status	ON Solid:	UTP link established
	Blinks:	No UTP link
	5-Blink pattern: UTP polarity reversal*
Transmit	Blinks when transmitting data on the RJ-45 cable
Receive	Blinks when receiving data on the RJ-45 cable

*Note: The E-TBT-MC04 corrects reverse polarity on its receiving port UTP cable automatically.

IMPORTANT Copper based media ports: e.g., Twisted Pair (TP) Ethernet, USB, RS232, RS422, RS485, DS1, DS3, Video Coax, etc. are intended connecting to intra- building (inside plant) link segments, not subject to lightening transients or power faults. Copper based media ports: e.g., Twisted Pair (TP) Ethernet, USB, RS232, RS422, RS485, DS1, DS3, Video Coax, etc. are NOT for connecting inter-building (outside plant) link segments that are subject to lightening transients or power faults. Failure to observe this notice could result in damage to equipment.
