Note Software controls the speed of the fans based on measurements from the chassis thermal sensors.

Sound power level
(AC and DC power)

Fan speed 3500 RPM, temperature 80°F (27°C):

77.2 dB—modular configuration power

Fan speed 5150 RPM, temperature 104°F (40°C):

88.8 dB—modular configuration power

Shock and vibration

Designed and tested to meet the NEBS shock and vibration standards defined in GR-63 Issue 3 March 2006.

1.Short-term refers to a period of not more than 96 consecutive hours and a total of not more than 15 days in 1 year. This refers to a total of 360 hours in any given year, but no more than 15 occurrences during that 1-year period.

2.Heat dissipation from the modular configuration DC power system based on maximum output power capacity at 90% efficiency.

3.Heat dissipation from the modular configuration AC power system based on maximum output power capacity at 92% efficiency.

Depending on the hardware deployed at your site, your system may not consume or be capable of consuming the maximum power supplied by the power system.
