Power
A good power supply system is essential for correct operation of the gateway. The gateway supports
AC and DC power inputs. Make sure the equipment room meets the following requirements for the
power supply systems.
•
The AC power supply system is stable and reliable and capable of providing power required by
the gateway. Prepare a diesel generator as a backup power source except for the power lines.
•
The DC power supply system is stable and reliable and its output voltage is stable and within
the acceptable range allowed by the gateway.
•
Enough batteries are available to ensure uninterrupted device operation in the event of a power
failure.
For the power supply system to provide power as required by the router:
1.
Calculate the system power consumption.
The system power consumption varies by module type and density. For more information about
system power consumption calculation, see "Appendix B Technical Specifications."
2.
Select power supplies and identify the number of power supplies.
The total maximum output power of all power supplies must be higher than the system power
consumption. For more information about available power supplies, see "Appendix A FRUs and
Compatibility Matrixes."
