Installation Instructions; Before You Begin - Dell PowerVault MD1120 Installation Manual

• Always load the rack from the bottom up, and load the heaviest item
in the rack first.
• Make sure that the rack is level and stable before removing or inserting
a component in the rack.
• Do not overload the AC supply branch circuit that provides power
to the rack. The total rack load should not exceed 80 percent of the branch
circuit rating.
• Ensure that proper airflow is provided to components in the rack.
• Do not step on or stand on any component when servicing other
components in a rack.

Installation Instructions

This installation guide provides instructions for installing one or more
systems in a four-post rack cabinet. The RapidRails™ rack kit can be installed
in all the system manufacturer's rack cabinets without tools; the VersaRails™
rack kit can be installed in most industry-standard rack cabinets. The
procedures for installing both RapidRails and VersaRails rack kits are similar.
One rack kit is required for each system to be installed in the rack cabinet.

Before You Begin

Before you begin installing your system in the rack, carefully read "Safety
Instructions" earlier in this guide. For additional information, also read
the safety instructions found in your Product Information Guide.
CAUTION:
When installing multiple systems in a rack, complete all of the
procedures for the current system before attempting to install the next system.
CAUTION:
Rack cabinets can be extremely heavy and move easily on their
casters. They do not have brakes. Use extreme caution while moving the rack
cabinet. Retract the leveling feet when relocating the rack cabinet. Avoid long
or steep inclines or ramps where loss of cabinet control may occur. Extend
the leveling feet for support and to prevent the cabinet from rolling.
NOTE:
For instructions on installing the system itself, see "Installing the System in
the Rack."
