Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage:
1. To avoid electrical shock, always disconnect the power from your PC chassis before you work on
it. Don't touch any components on the CPU card or other cards while the PC is on.
2. Disconnect power before making any configuration changes. The sudden rush of power as you
connect a jumper or install a card may damage sensitive electronic components.

Chapter 1. Product Introductions
1.1 Overview
MEGA-3110 series is a high-spec GPU system equipped with convertible expansion module
technology (CEM technology). It supports PCIe modular expansion functions and can be used with
nVIDIA RTX-2080 or higher GPU graphics cards or accelerator cards. It can reduce CPU loading and
increase the speed and ability of image processing.
What’s more, MEGA-3110 series uses Intel® 9th/8th CFL-R/S platform, which can support up to
octa-core processors. The configuration of 4x SATA and 2x CFast/ mSATA in the system is more
suitable for the storage and backup of large amounts of data. This series is ideal for image
recognition, security monitoring, unmanned intelligent vehicles, factory automation, machine
vision, and other fields.
