Rack warnings
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING: To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack
can weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and may become
unstable when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle
the rack from both sides.
Third-party racks
HP has not tested or validated the MDS600 with any third-party racks. Before installing the MDS600 in a
third-party rack, be sure to properly scope the limitations of the rack.
Site planning considerations
Customer facility managers and system administrators must discuss site planning, preparation, and system
installation before system delivery. A common understanding of environmental requirements and how the
systems will be delivered, configured, installed, and maintained helps to create a suitable data center and
aids the successful installation of the servers and related equipment.
It is important to plan the facility as a whole, not design based on calculations of individual system or rack
level requirements. Too many interdependencies in a modern data center make such simple calculations
unreliable. Designs and plans must be made for the data center as a whole, including all of its equipment,
with the realization that making one change in the data center environment can affect many other physical,
mechanical, and environmental aspects of the facility.
Take into account the requirements of third-party equipment and support equipment in the room. Dense
computing locations might have high power and cooling demands that could affect power and
environmental constraints. Be aware of rack positioning and airflow patterns. Ensure that the raised floor
space, cooling equipment, power supply equipment and generators, and other support equipment meet the
demands of all the servers and other mission-critical equipment.
Installing the enclosure
WARNING: The storage array with no drives installed weighs 72.58 kg (160.00 lb). With all
drives and components installed, the storage array can weigh up to 145.15 kg (320 lb). Before
configuring your rack solution, be sure to check the manufacturer weight limits and specifications.
Failure to do so can result in physical injury or damage to the equipment and the facility.
