C–22 Rack information
Hitachi Unified Storage VM Block Module Hardware User Guide
• An appropriate freight elevator must be available for transporting the
rack to upper and lower floors.
• Do not lay the rack down because the sheet metal may twist or distort.
• If the rack already has storage system components mounted in it, it may
be heavy (250 lbs. to approximately 1000 lbs).
Tools required for installation
The following tools are required for securing products to the rack-mounting
holes on a Hitachi rack:
• Adjustable wrench
• Cage nut tool
• Phillips screwdriver
All necessary screws, washers, cage nuts, and a cage nut too are suppled
with the rack. When installing equipment, be sure to:
• Install the front anti-tip stabilizing plate to provide greater stability and
safety. See Stabilizing the rack on page C-23 and Installing side
stabilizer plates on page C-25. Figure C-12: View of Hitachi Rack with
Side Stabilizer Plates Installed on page C-26 shows an how to install the
stabilizer plates.
• Mount heavier storage equipment such as the controller chassis at the
bottom of the rack first. Then install equipment in the upper half of the
rack.
Checking the hardware
If the rack is ordered empty, it should come with all components. If
additional features or options were ordered, or if the rack was ordered with
Hitachi Data Systems products pre-installed, verify that all items have been
received.
Casters
The casters enable movement of the rack across short distances in order to
position it for final installation. As soon as the rack is in its final position for
installation, adjust the leveling feet so that the full weight of the rack is
supported by them.
The casters can only support the weight of the rack with installed
components for short periods of time and not designed to support the full
weight of the rack on a long-term basis. If this occurs, the casters may be
damaged.
Leveling feet
The leveling feet, located beside each caster on the Hitachi rack, unscrew
and extend to the floor. These feet support the rack and help compensate
for uneven surfaces as shown in the following figure.
