Raised-ﬂoor Installations

The SGI Origin 3900 system does not require a raised-ﬂoor system. However, SGI

recommends a raised-ﬂoor system because it provides convenient routes for underﬂoor

air circulation and for power and communication cabling.

SGI recommends a minimum raised-ﬂoor height of 12.00 in. (305 mm).

Each rack that you install on a raised ﬂoor requires a ﬂoor cutout for cabling. When you

design your raised-ﬂoor system, place perforated ﬂoor panels or ﬂoor grilles near the

base of the front of the system racks, not directly under them. Figure 6-2 illustrates the

ﬂoor cutout for a single Origin 3900 rack.

The computer room ﬂoor must support the weight of all the system racks in your

conﬁguration. Each component rests on four leveling pads and casters that concentrate

the weight of the cabinet on a small surface area.

Additional ﬂoor support pedestals increase the ﬂoor-loading strength of the raised ﬂoor.

If your computer site lies in an earthquake zone, you can secure the computer system

components to the computer room subﬂoor for added stability. Refer to Chapter 7,

“Securing the Cabinets”, or contact your site planning representative for additional

details.

If you have any questions about the structural capabilities of any ﬂoor, please contact a

qualiﬁed structural engineer. If you do not install your system on a raised ﬂoor, SGI

recommends that you install ﬂat cable covers to protect cables from damage and to

protect computer room personnel from injury.
