Install The Weight Distribution Plate - IBM pseries 655 Installation Manual

Install the Weight Distribution Plate

Attention: Before installing the system, refer to the Site and Hardware Planning Information . Observe
the requirements in the Site and Hardware Planning Information relating to system weight, noise
emissions, power, and cooling.
The customer is responsible for consulting with a qualified licensed structural engineer, to determine if the
building concrete subfloor can withstand the floor loading specified in the Site and Hardware Planning
Information.
A fully populated system can weigh up to 1705 kg (3750 lbs.) with a 568 kg (1250 lbs.) concentrated load
acting on a caster. For multiple systems installation, it is possible that one floor panel will have two casters
from two adjacent systems causing 1136 kg (2500 lbs.) concentration loads into the panel. The customer
is responsible to consult the floor tile manufacturer to determine the load rating of the floor tile and the
pedestal structure supporting the floor tiles in order to ensure safe relocation and installation of the
system. Depending on the type of raised floor and the floor panel type, additional panel supports
(pedestals) might be required to restore structural integrity of the panel. Cable cutouts on a panel will
significantly reduce (up to 50 percent) the floor tile load rating. To avoid floor panel damage when moving
a system to its final installed location, it might be necessary to place protective material on the floor.
The weight distribution plate is intended for distributing load of a frame weighing more than 1136 kg (2500
lbs.) onto two floor panels. The weight distribution plate is designed for a raised-floor installation.
Note: Before performing the installation of the weight distribution, the rack must be located at its final
installation location.
1. If the rack has not been unpacked, remove all packaging and tape from the rack.
2. Position the rack according to the customer floor plan. Avoid positioning the rack on floor tiles that
have cutouts for cables or other wiring.
3. Lock each caster wheel by tightening the screw on the caster.
4. Be sure the rack is in the correct location.
5. Place a weight distribution plate (part number 11P3528) at the front and the rear of the rack, in the
approximate mounting position under the rack. Refer to the following illustration.
