Consideration Description
Lightning The user is protected under the UL codes against over voltage
in the system. However, the system itself is susceptible to over
voltage, such as lightning, depending on the configuration. The
loss of service because of an over voltage condition can result
in the loss of one or more of the following elements:
● Terminal loss
Power requirements
● Port loss
● Media Module loss
Acoustic noise generated 50 dBA maximum
Electromagnetic
compatibility standards
● Power supply within the G700
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
Air flow with the power
supply fan failure
In front of the backplane, airflow is 264 linear feet per minute
average. If a fan fails in front of the backplane, airflow
becomes 174 lfpm average, with a range from 42 to 340 lfpm.
Minimal air flow at power supply if power supply fan fails.
The power supply complies with FCC Part 15, Subpart B Class B and EN55022 Class B
requirements for conducted and radiated electromagnetic interferences (EMI). You can use the
power supply in single or multiple G700 Media Gateways. The power supply must allow the
system to comply with Class B requirements with +6 dB of margin.
This power unit can be a single power supply or multiple modules that are sized and scalable for
the load. The Avaya Ethernet switches have a power unit that meets the 802.3 AF standard and
provides remote power for the telephone. The power supply meets all applicable global
standards for safety, immunity, and emissions, and is verified by in-country testing.
