Table 17. Recommended operating points with the power on (continued)
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.
Table 18 gives the operating ranges that IBM recommends for an ESS with the
power on.
Table 18. Recommended operating ranges with the power on
Temperature 20 - 25°C (68 - 77°F)
Relative humidity 40 - 50%
Power off and storage environments
Table 19 gives the temperatures and humidity that IBM recommends for an ESS
with the power off.
Table 19. Recommended temperatures and humidity with the power off
Temperature 10 - 43°C (50 - 110°F)
Relative humidity 8 - 80%
Wet Bulb Temperature 27°C (80°F)
Table 20 gives the temperatures and humidity that IBM recommends for storing an
ESS.
Table 20. Recommended temperatures and humidity while in storage
Temperature 29°C (84°F)
Relative humidity 5 - 80%
Wet Bulb Temperature 29°C (84°F)
Recommended storage points or ranges
The recommended storage points or ranges are:
Wet bulb 29°C (84°F)
Temperature 1 - 60°C (34 - 140°F)
Relative humidity 5 - 80%
Energy saving law
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.
Power cable and power connector requirements
This section describes ESS power cable requirements and power connector
requirements. See “Power cables” on page 26 for the power-cable feature codes.
