Currently, any JACE-NXS ships with the SP2 (service pack 2) version of Windows XP Embedded (XPE). As shipped, Windows XPE on the JACE-NX may need to be updated with the latest security patches. In addition, a feature of Windows XPE SP2 is the Windows Firewall, which is factory-configured to permit network access to only selected TCP/IP ports used in NiagaraAX.
