Installation And Maintenance Precautions; Moving Racks With Casters; Connecting And Disconnecting Power To Hot-Pluggable Power Supplies - HP 245161-B22 - 10642 42U Rack Shock Pallet Best Practices Manual

Installation and maintenance precautions

To reduce the risk of electric shock or damage to the equipment when installing, maintaining, or
servicing Enterprise products, observe the general precautions listed in Table 5.
Table 5. Rack installation and maintenance precautions
Precaution
Follow manufacturer instructions
Be aware of power voltages and use
trained personnel
Secure all equipment
Provide overhead clearance for fire
sprinkler devices

Moving racks with casters

Racks with casters should be moved with care. Sudden stops, excessive force, and uneven surfaces
may cause the product to overturn. Both the 10000 and 10000 G2 Series Racks have casters which
are fixed in the front and swivel in the rear due to stability and safety concerns. Therefore, it is both
recommended and easier to move the rack with the back as the leading edge. For long, straight runs,
roll the rack with the front, fixed casters leading. For maneuverability when moving the rack into a
tight spot, it is better lead with the rear, swiveling casters. When rolling the rack, make sure to push
firmly on the front door frame and not the door mesh.
WARNING
To reduce the risk of personal injury or damage to the equipment, do not
attempt to move large equipment racks alone. Obtain adequate assistance
to stabilize the rack during movement or hire professional equipment
riggers.
CAUTION
To reduce the risk of damage to the casters, make sure that the full weight
of the rack rests on the leveling feet, and not on the casters. The casters are
designed only as an aid in moving the rack into position. They are not
designed to support the weight of the rack, and the casters may become
damaged if relied on to support the rack.

Connecting and disconnecting power to hot-pluggable power supplies

Observe the following guidelines when connecting and disconnecting power to the power supplies:
• Unplug the power cord before removing the power supply from the server.
• Install the power supply before connecting the power cord to the power supply.
• 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.
Description
Always refer to the individual equipment installation instructions for any special
considerations when installing equipment in a rack.
Some Enterprise products are capable of producing hazardous voltages and
hazardous energy levels. The installation of internal options and routine
maintenance and service of these products should be performed only by
individuals who are knowledgeable with the procedures, precautions, and
hazards associated with this type of equipment. Refer to the documentation
included with each product to determine whether it belongs in this category.
Unless the equipment is installed in a restricted access area, rack equipment
should be operated only with all enclosures in place and properly secured.
Always refer to the equipment installation guide and observe all applicable
warnings and precautions.
A minimum clearance is required between the top of the rack and any fire
protection sprinkler devices. Check your local building codes for details.
