Starting in AX-3.4, support was added for an Supervisor running on Red Hat Enterprise Linux 5 distribution on a specific PC platform (contact your Tridium sales channel for further PC platform details). This document provides installation details specific to this Linux Supervisor. For related details on NiagaraAX platform operation, see the NiagaraAX Platform Guide section “Linux-based Supervisor.”

Note that the station running on a Linux Supervisor is “owned” by a specially created user/group niagarad:niagarad, and therefore cannot bind to Linux “root owned” software ports 1-1024. This is not an issue for the conventional port (3011) used for a platform connection, but does affect the standard port used by the station’s WebService (Http Port), which cannot be used at the default port (80) setting. In addition, other software ports potentially used by various drivers must be adjusted above port 1024.
