Hi,
Does anybody know the motherboard diagnostic LED codes for Symmetricom 58503B (model of 2007)?
Note, in contrary to the well-documented Z3805A etc., the 58503B has only two diodes: red and a green one.
The 58503B seemed failed after a power cycle. Now kind-of reboots itself every few seconds.
Any service hints would be appreciated.

Best regards
Olgierd
