# System requirements

To install and use CG 6565E boards, your system must have:

- A chassis with an available PCIe bus slot with 12 V and 3.3 V of supplied power. The slot width must be x4 or wider.

- NaturalAccess installed.

Use an uninterruptible 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.
