G-RAID SHUTTLE SSD fans won't turn off

The fans on the G-RAID SHUTTLE SSD won’t turn off after shutting down the computer.
iMac - MacOS Big Sur 11.63.
The fans do turn off if I eject the hard drive and then unplug the thunderbolt cable from the computer. The power button does not seem to have any function at all. We have four of these units and they all do the same thing.
