Requirements and Tips
for Pre-Installation of Class One Systems

Server Hardware Requirements :

  • Hardware is recommended to be a device with an age of less than 3 years.
  • Minimum 8GB of RAM and 500GB of HD
  • We recommend 16GB and HD 1TB
  • 2 GHz or higher processor
  • Any improvement in hardware is always appreciated (RAID 1, 5, …) …
  • As is normal for being a server, the use of UPS (UPS) is recommended.
  • The Server must have a fixed static IP .

Requirements Router Ports addressed to the Server IP .

  • 9091 (for the operation of the Applications),
  • 22 for access by terminal (SSH) with username and password “sudoer” (port 22 is the default, but you can define another or redirect any other port on the external IP to 22 of said served

Essential for external access .

  • The establishment must have fixed public IP

Supported operating systems

Class One recommends Linux operating system.


  • Being under a Web platform, any hardware is valid in principle (notes, PC, Tablets, Smartphones, …), they must necessarily have a browser (browser). We recommend installing Google Chrome
  • Higher / lower job memory is significant when viewing large reports on jobs.

CWM – Customer Web Mobile

  • Due to its special accessibility characteristics, it is recommended that it be mounted on a different server, and even on another external hosting

External Backup

  • As typical security requirements, it is advisable to backup internally and externally.


  • We recommend that the server is always on a private network for its own safety.

Some Special Requirements

  • Some payment method interfaces require a proxy to redirect their requests to the program (port. 80, 443, …)
  • OTA’s must be registered and therefore in this case it is mandatory to have a fixed public IP.
  • Some Interfaces require a Windows system in a workstation and relate this in the Interface configuration in the Class One application. They can be connected by USB or have a folder that must be shared by network (VoXel) </ li>
  • Tickets printers must support 48 cls (columns) format, the example we give is the Epson TM-T20II
  • Tablet “kitchen caller”, acoustic warnings of the kitchen caller not compatible with iOS devices
