2 Unpacking and Assembling the Racks

This chapter describes the following procedures related to unpacking and assembling the racks
when they arrive at your site:
• Thermal stabilization (see
• Removing packaging from the racks (see
• Removing a rack from a pallet (see
• How to inspect the racks (see
• Leveling the racks (see
• Bolting the racks together (see
• Installing side panels (see

2.1 Thermal Stabilization

Before you remove the racks from their packaging, it is important to allow the cluster components
enough time to adjust to the local temperature and humidity of their new operating environment.
Failure to thermally stabilize cluster components can potentially damage drive media or associated
electronics when you activate the cluster.
Environmental stabilization begins when the equipment is placed in the room in which it is to
be installed. If the rack arrives in a plastic bag, leave the bag in place until the rack has adjusted
to the local temperature and humidity. To ensure proper operation of storage devices, the rack
temperature must be within 18°–29°C (65°–85°F).
stabilize racks based on the ambient shipping temperature.
If condensation is visible on the rack or on any component inside the rack, stabilize the rack in
the operating environment for 6 hours or until the condensation is no longer visible, whichever
is longer. If condensation is not visible, thermally stabilize the rack for the amount of time specified
in Table 2-1.

2.2 Removing Rack Packaging

The racks arrive at the installation site on a loading pallet surrounded by layers of protective
plastic, corrugated cardboard packaging, and stretch film. The side of each box is printed with
a few basic diagrams that show how to remove the rack from its packaging and from the pallet;
