System Requirements for YCM Server

To deploy YCM Server, you need to know the requirements of hardware, Ethernet port, and operating system.

Important: The private subnet of the server MUST be set to one of the following subnet options, otherwise the server installation would fail.
  • 10.0.0.0/8
  • 172.16.0.0/12 (excluding the 172.17.x.x and 172.19.x.x IP address ranges)
  • 192.168.0.0/16
Tip: We provide a server calculator to help you calculate the required server configurations for the entire deployment of Yeastar P-Series Cloud PBX. For more information, see Server Calculator.
