the center guide tab at the bottom of the housing goes into the slot on the
center support of the component mounting bracket.
3. Insert the two screws and, using a Phillips-head screwdriver, tighten the
screws to secure the component mounting bracket to the chassis.

bays from which they were removed.
NOTE: A redundant storage system has two enclosure services modules or
enclosure services expander modules. A nonredundant storage system has a
single expansion services module or enclosure services expander module and
a terminator blank. Because an enclosure services module, enclosure services
expander module, and a terminator blank install in the same manner, all these
components are referred to as an enclosure services module in this procedure.
To install the enclosure services modules, perform the following steps:
