Unpacking the system
NOTE: Unpacking, installing, and deploying your Dell Storage must be carried out only by a certified
service technician.
Before you begin, make sure the site where you intend to set up and use the Dell Storage has the
following:
• 208 V power from an independent source or a rack power distribution unit with a UPS (110 V power
will not work.).
• A 5U space in the lower 20U of the rack. If planning to install above the 20U mark, a customer-
provided mechanical lift must be made available.
Installation overview
The installation process includes the following general tasks.
CAUTION: If installed in a closed-or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient temperature. Therefore, install the
equipment in an environment compatible with the maximum ambient temperature (Tma)
specified by the manufacturer. For more information, see the Technical Specifications section in
this document.
1. Assemble the rails following the safety instructions and the rack installation instructions provided
with your system.
2. Unpack the enclosure.
WARNING: Two people using lift straps are required to avoid injury.
3. Install the enclosures into the rack.
• Always load the rack from the bottom for weight stability.
• If you have fewer than the maximum number of enclosures, you can allow room for expansion.
