The z15 can be installed on a raised or non-raised floor. For more information about weight distribution and floor loading tables, see IBM 8561 Installation Manual for Physical Planning , GC28-7002. This data is used with the maximum frame weight, frame width, and frame depth to calculate the floor loading. 

Weight estimates for the maximum system configurations on the 8561 are listed in Table 11-12.

Notes: Consider the following points: 

GLYPH<SM590000> Weight is based on the maximum system configuration. 

GLYPH<SM590000> All weights are approximate and do not include Earthquake Kit hardware. 

GLYPH<SM590000> Be certain that the raised floor on which you are installing the server can support the weight. 

The power and weight estimation tool for Z servers on Resource Link covers the estimated weight for your designated configuration. It is available on IBM Resource Link website. 

## 11.3 Physical planning 

On the Resource Link page, click Tools → Power and weight estimation . 

This section describes the floor mounting, power, and I/O cabling options. For more information, see IBM 8561 Installation Manual for Physical Planning , GC28-7002. 

## 11.3.1 Raised floor or non-raised floor 

z15 servers can be installed on a raised or non-raised floor. The water-cooled models require a raised floor. 

Note:  On the z15, all I/O cabling and power cords come from the rear of the machine; therefore, all related features for Bottom and Top Exit cabling are in the rear of the frame.
