Additional Manufacturer Narrative
|
|
The customer confirmed that they did not perform a site survey prior to changing the wireless infrastructure to wlc cisco 9800l 17.9.5 ap - catalyst 9120ax.However, after changing over to this new network, testing was performed by the hospital biomed and it to test access points for using m300s, prior to using the devices with patients.No failures were found during this testing.The new infrastructure was then deployed on a single patient floor, but despite having no failures during testing, the customer found multiple m300 dropouts/offline conditions occurred.The customer returned to using their original infrastructure, wlc cisco airos 5508 running software version 8.5.151.0, to prevent further dropouts from occurring.Draeger was contacted to investigate the issue.The draeger field service engineer (fse) conducted tests using m300s with simulated data and no failures were observed during testing.However, when a patient worn device was used, the issue was observed.The log files from the fse visit at the customer's site were reviewed and found there were long stretches of retransmissions from the m300s with no response followed by probing for a new access point, indicating the root cause was related to the network.Draeger confirmed that the new infrastructure was not fit for patient use as there were too many dropouts.The customer permanently returned to their original wireless infrastructure and no further issues have been reported.Draeger recommended the customer contact cisco for further assistance regarding the use of the new infrastructure.The m300 devices were found to operate as intended and the root cause for the reported event was tied to the new cisco wireless network that used by the customer.
