Attention:
If you deviate substantially in either direction from these recommended operating points for extended, consecutive
hours, you expose the ESS to malfunction from extreme causes.

ESS Introduction and Planning
Table 18 gives the operating ranges that IBM recommends for an ESS with the
power on.
Table 19 gives the temperatures and humidity that IBM recommends for an ESS
with the power off.
Table 20 gives the temperatures and humidity that IBM recommends for storing an
ESS.
The recommended storage points or ranges are:

Relative humidity
The energy savings for all ESS models is:
0.001 Watts/MB for MB > 160, Category G.
Power consumption in energy savings mode is not applicable.
This section describes ESS power cable requirements and power connector
requirements. See "Power cables" on page 26 for the power-cable feature codes.
