Installing The FLEX Bay M.2 Enclosure
The FLEX Bay enclosure is an optional kit that will need to be purchased
separately if it was not ordered when the original system was built. See
for additional information and images of parts.
1. Locate the area in the chassis where the FLEX bay kit will be installed.
2. If it has not already been removed, remove the FLEX Bay bezel cover and
metal insert. From inside the system (1) lift the two tabs to release the
bezel cover and then (2) push on the center post to pop the bezel cover
out.
