Preparing for installation

NOTE: Enclosure configurations
•
2U enclosures are delivered with CRUs and all drive carrier modules installed.
•
5U enclosures are delivered with many CRUs installed; however, DDICs must be installed during system setup.
CAUTION: Lifting enclosures
• A 2U enclosure—together will all its component parts—is too heavy for one person to lift and install into the
rack cabinet. Two people are required to safely move a 2U enclosure.
