Operating Humidity
0 to 95 percent non-condensing
Storage Humidity
0 to 95 percent non-condensing
Maximum Operating Altitude
3,048 m (10,000 feet) above sea level
Storage Altitude
0 to 12,192 m (0 to 40,000 feet) above sea level
Acoustic Noise
At 25°C Ambient Temperature, less than 48 dBA
typical, at 50°C, less than 61 dBA.
Miscellaneous Operating Considerations
• No nearby heat sources such as hot air vents or
direct sunlight
• No nearby sources of severe electromagnetic
noise
• No excessive dust
• Adequate power source within six feet; one circuit
required for each power supply (see table, AC
power specifications)
• At least 2 inches (5.08 cm) on each side of the
switch unit for ventilation
• Cables should be dressed to prevent blocking air
flow.
