Today, April 13, 2018, we updated the MSA Firwmare site (www.hpe.com/storage/MSAFirmware). It now includes the latest Drive Enclosure Firwmare for the MSA Expansion module and the D2700.
At top of the page you will see a new tab/button to click to view the "Drive Enclosure Firmware"
Take a look and feedback is always welcome.
Cheers!
