Cutting and Placement of Floor Panels
This section provides recommendations for making the necessary openings in the raised floor for installing
the Eserver pSeries 655.
The x-y alphanumeric grid positions are used to identify relative positions of cutout floor panels that may
be cut in advance.
1. Measure the panel size of the raised floor.
2. Verify the floor panel size. The floor panel size illustrated is 600 mm (23.6 in.) and 610 mm (24 in.)
panels.
3. Ensure adequate floor space is available to place the frames over the floor panels exactly as shown in
the illustration. For front-to-back and side-to-side clearances, refer to "Considerations for Multiple
System Installations" on page 115. Use the plan view if necessary. Consider all obstructions above and
below the floor.
4. Identify the panels needed, and list the total quantity of each panel required for the installation.
5. Cut the required quantity of panels. When cutting the panels, you must adjust the size of the cut for
the thickness of the edge molding you are using. The dimensions shown in the illustrations are finished
dimensions. For ease of installation, number each panel as it is cut, as shown in the following
illustration.
Note: Depending on the panel type, additional panel support (pedestals) may be required to restore
structural integrity of the panel. Consult the panel manufacturer to ensure that the panel can
sustain a concentrated load of 567 kg (1250 lbs). For multiple frame installation, it is possible
that two casters will produce loads as high as 1134 kg (2500 lbs).
6. Use the raised floor diagram on the next page to install the panels in the proper positions.
Notes:
a. This floor-tile arrangement is recommended so that the castors or leveling pads are placed on
separate floor tiles to minimize the weight on a single floor tile. Furthermore, we recommend that
tiles bearing the weight (having castors or leveling pads on the tiles) be uncut to retain the strength
of the floor tile.
b. The following illustration is intended only to show relative positions and accurate dimensions of
floor cutouts. The illustration is not intended to be a machine template and is not drawn to scale.
