# System requirements

To install and use AG 2000C boards, your system must have:

- Natural Access installed.

- A CompactPCI chassis with an H.110 compliant backplane and an available CompactPCI bus slot.

Note: The AG 2000C board can power up and function only in a chassis with a telephony backplane.

- A grounded chassis (with a three-prong power cord).

NMS recommends an uninterruptable power supply (UPS) for increased system reliability. The UPS does not need to power the PC video monitor except in areas prone to severe lightning storms.
