The reported issues was discovered during training by the user facility.Per the manufacturer's subsidiary, the user facility's service technician found that all pumps worked as intended when attached to the left side of the pump, and only one pump worked on the right side.After attaching any second module, all modules attached to the right side went down.He reassembled the network interface card (nic) board of the right side and the unit worked as intended.

The reported complaint was confirmed.Per data log analysis, on (b)(6) 2018, the central control monitor (ccm) is intermittently sending specific reset request to several modules: air bubble detector, occluder, temperature, level, pressure, large roller pump.Only one of the modules logs (temperature) covered that date and it was reporting ¿5v supply voltage test failure¿ events.This will then cause the red ¿x¿ and possible a ¿?¿ as reported.Most likely all of the listed modules were reporting the 5v error.If all were connected to the same network interface card (nic) the possible causes are the power manager, the nic, or the power cable that connects the power manager to nic.The cable connection is the most likely cause.If additional information becomes available on this complaint that would alter the facts and/or conclusion, a supplemental report will be filed accordingly.
