LED State Description
DUP Green
Gray
The media converter is operating in full-duplex mode.
The media converter is operating in half-duplex mode.
AN Green The 10/100Base-TX port is auto-negotiating.
Note - Connection cannot be established between a 10/100Base-TX port on an AT-PB200 series
module that is configured to auto-negotiate and a 10/100Base-TX port on another AT-PB200 series
module that is configured to operate at 100 full/half duplex.
Note - The current firmware version allows the Port A Speed parameter to be set to '10M' even if Port
A is only capable of operating at a speed of 100Mbps.
Note - The current firmware version allows the Port A Mode parameter to be set to 'auto' even if Port
A is not capable of auto-negotiation.
Note - When the Port B Mode parameter is set to 'auto', the current firmware version is unable to
provide information on the negotiated speed and mode for Port B. As a result, the speed reflected on
the port image may be a '10' when it should really be '100' and vice-versa. Also, expect the DUP
LED to be gray when it should really be green or orange.
