We have an MX2800 DS3 AC Redundant with RJ Patch Panel & I see the warranty expiration is 10/27/2018. We are running the 3.42A code. I don't see an End-of-Life announcement for this product. Please let me know if Adtran is planning to release any updated hardware for this line. The only design suggestions I’d make are about the power. The current unit runs only on 110VAC. It would be great if the unit could run on 220VAC power. It would also be great if the chassis power had redundant, field-replaceable power supplies. We have been very pleased with the performance of this multiplexer & hope Adtran continues to innovate this product line.
You are correct the MX2800 is not considered to be End-of-Life. Software version 3.42A is the current released software. There are three redundant power options for the MX2800 110VAC via Power Supply Module P/N 1202289L1, -48VDC via Power Supply Module P/N 1202289L2, and +/- 24VDC via Power Supply Module P/N 1202289L3. These units are field replaceable by removing the front cover secured by a single thumb screw.
