Sound power, operating - 6.2 bel for open bay system (no hard disk drives installed) - 6.3 bel for typical system configuration (1 hard disk drive installed) Sound pressure, idling - 47 dBA for open bay system (no hard disk drives installed) - 48 dBA for typical system configuration (1 hard disk drive installed) Sound pressure, operating - 47 dBA for open bay system (no hard disk drives installed) - 48 dBA for typical system configuration (1 hard disk drive installed) These levels are measured in controlled acoustical environments according to ISO 7779 (EMCA-74), and are reported in accordance with ISO 9296 (EMCA-109). The declared sound power levels indicate an upper limit, below which a large portion of machines operate. Sound pressure levels in your location might exceed the average 1-meter values stated because of room reflections and other nearby noise. Electrical Input Sine-wave input (50±3 Hz or 60±3 Hz) is required Input voltage - Low range - Minimum: 90 V ac - Maximum: 137 V ac - Nominal: 100-127 V ac - High range - Minimum: 180 V ac - Maximum: 265 V ac - Nominal: 200-240 V ac - Input kilovolt-amperes (KVA) approximately - Minimum configuration as shipped: 0.2 KVA - Maximum configuration: 0.78 KVA Electrostatic Discharge Tested to 8 KV Immunity Verified to comply with EN 50082-1 Safety Standards UL 1950 CSA C22.2 No. 950-M93 EN 60950 and countries/regions deviations IEC 950 NOM-019 62 Netfinity Server HMM
