IBM DS6000 Series Power requirements, Environmental requirements, Input voltage requirements

Use the following steps to calculate the required space for your storage units:

1.Determine the dimensions of each model configuration in your storage units.

2.Determine the total space that is needed for the storage units by planning where you will place each storage unit in the rack.

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

7.2.2Power requirements

We describe here the input voltage requirements for the DS6000 series.

Input voltage requirements

The DS6000 series has built-in redundant, auto-sensing, auto-ranging power supplies. The power supplies are designed for operation in a voltage range of 90-257 V AC, 50-60 Hz.

Table 7-4lists the input voltages and frequencies that the DS6000 series power line cords support. The values apply to both of the primary line cords to any storage or expansion enclosure in a DS6000 series. The DS6000 series power inputs are single phase.

Table 7-4 DS6000 series input voltage requirements

Characteristic	Value
Nominal input voltages	100-127 RMS V AC
	200-240 RMS V AC
Minimum input voltage	90 RMS V AC
Maximum input voltage	264 RMS V AC
Input frequencies	50 ± 3.0 Hz
	60 ± 3.0 Hz

Two independent power outlets for the two DS6000 power line cords are needed by each base model and expansion model.

Important: To eliminate a single point of failure, the outlets must be independent. This means that each outlet must use a separate power source and each power source must have its own wall circuit breaker.

7.2.3 Environmental requirements

To properly maintain your DS6000 storage unit, you must install your storage unit in a location that meets the operating environment requirements.

Table 7-5describes the environment operating requirements for the DS6000 series.

Table 7-5 Operating environment

Powered on temperature limit	10 - 40° C (50 - 104° F)
Powered off temperature limit	10 - 52° C (50 - 126° F)
