2.Calculate the total area that is needed for the model configuration by adding the weight distribution area to the dimensions.

3.Determine the total space that is needed for the storage units by planning where you will place each model configuration in the storage units and how much area each configuration will need based on step 2.

4.Verify that the planned space and layout also meets the service clearance requirements for each unit and system.

Note: The DS8000 requires service clearances of 121.9 cm (48 inches) at the front and

76.2cm (30 inches) at the rear. Racks can be placed side by side if floor loading restrictions allow this.

8.3.2Power requirements

When you consider the DS8000 storage complex location, consider the following issues:

￿Power control selections

￿Power outlet requirements

￿Input voltage requirements

￿Power connector requirements

￿Power consumption and environment

Power control

The DS8000 provides power controls on the model racks and through the Management Console.

The DS8000 models have the following manual power controls in the form of physical switches on the racks:

￿Remote force power off (Remote FPO) switch (available on base models)

Planning requirements: To use this feature, you must supply a remote force power off circuit. See the DS8000 Introduction and Planning Guide, GC35-0495, for more detailed information.

￿Local/remote switch (available on base models)

￿Local power on/local force power off switch (available on base models)

￿Unit emergency power off (UEPO) switch (available on all models)
