Prosafe M4100-50G-POE+ failed after update
Hello I have a M4100-50G-POE+ which has failed after a firmware update, the power led is blinking orange. Most manuals says it has failed POST, one of them says the power supply has failed - is...
Hi waynefury,
Welcome to the community!
As I checked the initialization process of the switch that it can't load the flash2.stk1. This is a bad firmware upgrade result that it cannot load the image from the flash. May I know what firmware version are you trying to upload? Please make sure that your are uploading the correct firmware for your M4100 device. You may still recover the switch by reflashing the switch via CLI using XModem.
Please refer to this link. Hope this helps.
Regards,
Hi JohnCarloV
Thank you for your reply and the link to the recovery procedure.
Looking at my CLI output it appears that the switch has no access to its flash memory (so I never get to "Starting program at 0xXXXXXXXX" and cannot stop the boot sequence and enter the boot menu in the link provided).
It all seems to go astray at the line starting "Loading:"
The example in your link continues with "STK image is 12324100 bytes, CRC 0xFC98 3605504 bytes"
The switch I am working on returns " Could not load flash2.stk1:: Error"
Prior to that there are also "not enough PCI mem space" errors (lines starting PCI)
However I can get to the CFE> prompt by pressing Ctrl-C, is there another recovery procedure I can use?
Thank you
Wayne
