Planning Your Installation
Chassis grounding is provided through the power cable, which uses a standard grounding plug. However, the
chassis also requires a reliable earth ground using the earth ground lug and hardware provided. For more
information, see the Chassis Grounding section.
Power Source and Supply
Check the power at your site to ensure that you are receiving "clean" power (free of spikes and noise). Install
a power conditioner if necessary.
A Cisco VG400 Voice Gateway with AC power supply auto selects power ranging from 100-240V. AC
versions include a 6-foot (1.8-meter) electrical power cord.
Caution
Cisco VG400 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 VG400 Voice Gateway is a viable option when the UPS is not co-located with it.
