Is it possible that the UPS takes the load also when it is in Bypass

[idanst_apc]

Hi 

I have APC Symmetra PX 100kW Scalable to 100kW, with 5 modules. 

the UPS suddently move to bypass and after few hours come back to normal

we suspcet that event when we get the bypass alert it is still available and when there is a power failure it goes to on battery with out the shutting the server down. is it possible?

sometimes the UPS goes to by pass due to "In bypass in response to the UPS front-panel or a user-initiated software
command, typically for maintenance" although nobody touches it and some time due to overload which we dont understand why it happen

Hi,

Can you provide the full event.txt, data.txt, and config.ini files for review please? That will also share with me the firmware version on your Management Card in the UPS.

Also, I am curious to know what firmware version is on your UPS. Could you check under the UPS->Intelligence System and tell me what's under there for firmware version?

With that information, hopefully we can better tell what is going on exactly. I'd also verify there is nothing physically connected to the UPS serial port(s).

Hi 

I will try to collect the info you got but I now understand that the UPS has problem and I have some spares in stock. so the following question is much urgent 

My UPS has  a power module rack SYCF40KH and Batteries Rack SYCFXR8

Will it possible to replace the power module rack SYCF40KH with power module rack’s SYCF48KH that I have in stock, use only new power modules with 16KVA capacity (SYPM10K16H) and continue to use the same batteries and battery rack (SYCFXR8)?

Best Regards

Hi Idan,

I had to inquire with our 3 phase support team in EMEA for help with this. If you have further time sensitive questions along the same lines, I'd suggest you contact the local technical support office in your area.

The answer is: Unfortunately the older XR frame designed for the Symmetra PX products (specifically 20/40
