DX4000 doesn't power on

When turning on the enclosure, nothing happens aside from red LED showing in bays 1 and 3. The display doesn’t turn on and neither does the fan. Same result with no drives inserted.

sounds bad. Contact support.wdc.com

Enclosure is no longer under warranty.

most likely the power supply failed

Have tried a number of known working A/C adapters to no avail.
