Chapter 2: Hardware Installation
2.1 Installation Requirements
Before installing the Content Security Gateway, make sure your network meets the following requirements.
- Mechanical Requirements
The Content Security Gateway is to be installed between your Internet connection and local area network.
The Content Security Gateway can be placed on the table or rack. Locate the unit near the power outlet.
- Electrical Requirements
The Content Security Gateway is a power-required device, it means, the Content Security Gateway will not
work until it is powered. If your networked PCs will need to transmit data all the time, please consider use
an UPS (Uninterrupted Power Supply) for your Content Security Gateway. It will prevent you from network
data loss. In some area, installing a surge suppression device may also help to protect your Content
Security Gateway from being damaged by unregulated surge or current to the Content Security Gateway.
- Network Requirements
In order for Content Security Gateway to secure your network traffic, the traffic must pass through Content
Security Gateway at a useful point in a network. In most situations, the Content Security Gateway should
be placed behind the Internet connection device.
