  • If you are using a dedicated network, the branch server requires at least two network interfaces: one connected to the WAN with a reachable SUSE Manager Server, and one connected to the internal branch LAN.

  • Terminals require a LAN connection to the branch server network.

5. POS Terminal Requirements

Table 4. Hardware Requirements for Terminals
Hardware Recommended

RAM:

Minimum 1 GB for hosts that need to run OS images built with Kiwi (PXE booted or not)

Disk Space:

Disk space depends on size of the OS image

For more information, see the documentation of the underlying system (in this case: SUSE Linux Enterprise Server 15).

For more information on SUSE Manager for Retail POS terminals, see documentation on SUSE Manager Salt clients (client-configuration:client-config-overview.adoc).

5.1. UEFI Secure Booting Requirements

Secure boot from the network using UEFI PXE or UEFI HTTP is supported on both SUSE Linux Enterprise Server 12 and SUSE Linux Enterprise Server 15. Booting from a hard disk using UEFI Secure Boot is fully supported on SUSE Linux Enterprise Server 15 images only.

You cannot boot SUSE Linux Enterprise Server 12 images using UEFI secure boot from a hard disk. This is due to limitations with the legacy Kiwi service. You need to either disable UEFI secure boot, or upgrade your terminals to SUSE Linux Enterprise Server 15.
