- Potential poor image quality. A single loss of sync it not likely to cause visual problems for a display, but if multiple losses of sync occur in a ProLink5 circuit, particularly a system that lacks redundant PLRs, all modules between the points of failure may go blank.
IDM / System Health Event(s)
- Loss of Sync (ProLink5, Port A or Port B)
- Product Family:
- Product: System Health, IDM
- Component: PLR
- Control System: Venus Control Suite
- The PLR receives ProLink5 data on two ports - A and B. A loss of sync on one port will cause the PLR to switch to the other port. While a loss of sync itself is a non-visual event, it may be caused by the reset or failure of a module directly connected to the PLR, and therefore may be an indirect indicator of a visual outage.
- If redundant PLRs are not configured, a persistent loss of sync on a ProLink5 circuit indicates that module data redundancy has been lost. Another loss of sync on the same circuit will result in a visual outage affecting all modules between the two points of failure.
- If redundant PLRs are configured, you may experience a loss of sync on a PLR ProLink5 without a loss of module redundancy, provided that all modules are in sync on both ports.
If redundant PLRs are not configured, look for events indicating that the module connected to Port A or B (depending on the alert) of the PLR experienced a reset or diagnostic failure, and use the display's webcam to determine if there are any visual issues occurring on the display.
If no such events exist, inspect the Serial ATA cable connection between the PLR and the module connected to Port A or B (depending on the alert) of the PLR.
If redundant PLRs are not configured, determine whether a loss of sync on Port A or B (depending on the alert) of the PLR is expected.
