Facility Characteristics

This section contains information about facility characteristics that must be considered for the installation or
operation of an HP 9000 rp4410 or HP 9000 rp4440 server. Facility characteristics are:

•

Floor loading

•

Windows

•

Altitude effects

Floor Loading

The computer room floor must be able to support the total weight of the installed cabinets, servers, and
associated equipment as they are moved into position.

Floor loading is usually not an issue in nonraised floor installations. The information presented in this section
is directed toward raised floor installations.

NOTE

An appropriate floor system consultant should verify any floor system under consideration for
an HP 9000 rp4410 or HP 9000 rp4440 server installation.

Raised Floor Loading

Raised floor loading is a function of the manufacturer’s load specification and the positioning of the
equipment relative to the raised floor grid. While HP cannot assume responsibility for determining the
suitability of a particular raised floor system, it does provide information and illustrations for the customer or
local agencies to determine installation requirements.

The following guidelines are recommended:

•

Because many raised floor systems do not have grid stringers between floor stands, the lateral support for
the floor stands depends on adjacent panels being in place. To avoid compromising this type of floor
system while gaining under-floor access, remove only one floor panel at a time

•

Larger floor grids (bigger panels) are generally rated for lighter loads

CAUTION

Do not position or install any equipment cabinets on the raised floor system until you have
carefully examined it to verify that it is adequate to support the appropriate installation.
