Typical config: 22.8kg (50.4lbs.)
Maximum config: 29.2kg (64.3lbs.)
Temperature Operating: 5° to 35°C (40° to 95°F)

Humidity Operating: 8% to 85%
Non-operating 8% to 90%
Maximum Altitude (non-
pressurized)

Power Supply Choice of:
850W 88% Efficient wide-ranging, active Power Factor Correction
1125W 90% Efficient wide-ranging, active Power Factor Correction
NOTES : The 1125W power supply can also supply 1275W of output power when the input voltage is
greater than 105V. If the input voltage is less than 105V, but greater than 90V for any reason, the
maximum power that can be drawn is 1125W. An uninterruptible power supply (UPS) is highly
recommended if 1275W output power is desired.
