removing the MBM. Refer to“To remove a wallmounted expansion unit” on page 185 for
more information, then proceed to step 7.

If there is more than one cable, mark the cables to identify the port from which they were
removed.

surface.
7 Pull the ejector lever out with your index finger. Then grasp the ejector lever with your thumb
and index finger and pull outward to disengage the MBM (see Figure 67). Finish removing the
MBM by hand.
