Environmental Considerations for the G700 Media Gateway
Consideration Description
Heat dissipation The unit uses global AC, 100-240 VAC, 50/60 Hz, 1.5
to 4.9 A, which translates to 360 to 400 Watts. However,
some is passed out the front, via -48VDC (up to 32 ports
at 1.5 Watts each for a total of 48 Watts).
Altitude and air pressure Functions at altitudes of minus 197 feet to 10,000 feet.
Air pressure is not specified.
Temperature and humidity Long term operation at +5 to +40 C at 5 to 85%
humidity. Short term operation at -5 to 50 C, at 5 to 90%
humidity, non condensing.
Air purity Indoor environments that are suitable for continuous
human occupancy.
Lightning The user is protected under the UL codes against over
voltage in the system. However, the system itself is
susceptible to over voltage (i.e. lightning) depending on
the configuration. The loss of service due to an over
voltage condition can result in the loss of one or more of
the following:
• Terminal loss
• Port loss
• Media Module loss
• Power supply within the G700
Acoustic noise generated by
unit
50dBA maximum
Electromagnetic compatibility
standards
Conforms to the electromagnetic compatibility
standards for the countries in which it operates.
European union standards Approved to Safety Standard EN60950.
Air flow with a single fan
failure
In front of the backplane is 264 linear feet per minute
average. If a fan fails in front of the backplane, 174
lfpm average, with a range from 42 to 340 1fpm.
Air flow with the power supply
fan failure
Minimal air flow at power supply if power supply fan
fails.
