to install it in the rack. Even after the drives, power supply units, secondary
expander modules, canisters, fans, and top cover are removed, the enclosure

shows an example.

expansion enclosure above position 22U in the rack.

service task (for example, replacing the enclosure), you must also perform the
following tasks:
v Reinstall all of the following parts:
– Cover
– Drives
– Fan modules
– Power supply units and 1U fascia
– Secondary expansion modules
– Expansion canisters (and SAS cables)
v Reconnect both power cables to the expansion enclosure.
