Per data log review, on 22-dec-2020, many of the pumps and modules were reporting '5 volt (v) supply voltage test failures'.This will cause an alarm tone to sound, failed indications on the main screen, and a red x on the pump and module icon as reported.The following are the pumps and modules that reported the 5v error.Some of the logs did not export properly so there were likely more that had the 5v issue.The log confirms the complaint, the likely cause is in the power cable from the power manager to the right network interface card (nic), the power manager, or the nic.During laboratory analysis, the product surveillance technician (pst) observed some significant buildup on the three fuses associated with the 5v line, removing and re-seating the fuses restored some of the original contact surface.The reported complaint was not reproduced during evaluation.
