Note
  1. Chassis is powered on.
  2. Chassis is removed from original shipping container and is installed but not in use, for example, during repair, maintenance, or upgrade.
  3. A3 - Derate maximum allowable temperature 1°C/175 m above 950 m.
  4. 5°C/hr for data centers employing tape drives and 20°C/hr for data centers employing disk drives.
  5. The minimum humidity level for class A3 is the higher (more moisture) of the -12 °C dew point and the 8% relative humidity. These intersect at approximately 25°C. Below this intersection (~25C) the dew point (-12 °C) represents the minimum moisture level, while above it relative humidity (8%) is the minimum.
  6. Moisture levels lower than 0.5°C DP, but not lower -10 °C DP or 8% relative humidity, can be accepted if appropriate control measures are implemented to limit the generation of static electricity on personnel and equipment in the data center. All personnel and mobile furnishings and equipment must be connected to ground via an appropriate static control system. The following items are considered the minimum requirements:
    1. Conductive materials (conductive flooring, conductive footwear on all personnel that go into the datacenter, all mobile furnishings and equipment will be made of conductive or static dissipative materials).
    2. During maintenance on any hardware, a properly functioning wrist strap must be used by any personnel who contacts IT equipment.
  7. The equipment acclimation period is 1 hour per 20 °C of temperature change from the shipping environment to the operating environment.
  8. Condensation is acceptable, but not rain.
  9. Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use.
  10. The noise emission level stated is the declared (upper limit) sound power level, in bels, for a random sample of machines. All measurements are made in accordance with ISO 7779 and reported in conformance with ISO 9296. Actual sound-pressure levels in a given location might exceed the average values stated because of room reflections and other nearby noise sources. The noise emission level stated in the declared (upper limit) sound-power level, in bels, for a random sample of system.
