storage system are already connected in a SAN or direct attach
configuration. Complete the tasks highlighted with grey in the
checklist before the service provider arrives.
The Without Access Logix column does not apply to CX300, CX500, and
CX700 storage systems because they ship from the factory with the Access
Logix enabler installed.
