Cisco UCS C220 M4S FlexFlash Controller Replacement

[joshua.krugjohann]

Hi,

I have a project in which I am upgrading 3 Cisco C220 M4S's to ESXi 6.7 (PID: UCS-SP-C220M4-A1). 

One of the hosts seems to have a bad FlexFlash controller in it.  I've not worked on M4's much, but in my research, it's been suggested in at least one place that M4's don't have field replaceable FlexFlash Controllers but rather need the whole motherboard replaced. 

Can anyone confirm this?

I've included screenshots of the server hardware fault on the server in question from UCS Manager in case anyone wanted to see it, but i think this is more of a hardware question than troubleshooting at this point.

Thanks in advance, any help is greatly appreciated.

You are correct.

The SD card slots (and related controller chipset) are part of system board in the 220 m4s.

Assuming you have attempted:

• power drain
• reset CMOS settings
• reset FX3/flexflash controller
• HUU upgrade

Hi Kirk, thank you for the confirmation.  By the screenshots above, does this seem to indicate the FlexFlash controller itself is bad, or that I should simply replace the SD cards?  I can provide more screenshots if needed.

The error is saying the actual flexflash controller is not responding..
