Chapter 3 Planning Your Installation
Location and Mounting Requirements
Power Source
A Cisco VG350 Voice Gateway with AC power supply autoselects either 100–127 volt or 200–240 volt
operation. AC versions include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord
indicates the correct voltage, frequency, current draw, and power dissipation.)
Power Suppy Considerations
Cisco VG350 Voice Gateway requires significantly more power because of its high-density ports and
OPX ‘Lite’ requirements.
This require a larger 48V battery backup that may need to be custom built.
To handle power failure conditions, an uninterrupted power supply (UPS) is needed. UPS is widely
available in all markets, including emerging markets (due to prevalence of UPS for personal computers).
Thus, a separate UPS for Cisco VG350 Voice Gateway is a viable option when the ISR/UPS is not
co-located with it.
If you suspect that your AC power is not clean—if lights flicker often or there is machinery with large
motors nearby—have a qualified person test the power. Install a power conditioner if necessary.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
