Prior to running a Linking system, verify Primary and Satellite Luxors have the latest version of Facepack (Primary controller only) and chassis (Primary and Satellite) linking firmware. For instructions on updating your firmware, click here. Chassis firmware updates take about 15 minutes. The progress bar, shown at the bottom of the face pack, indicates the progress of the firmware update. Do not unplug the power of the Cat 5/Cat 5e/ Cat 6 connections while firmware updates are in process.
