lost operational code / firmware due to internal battery replacement ?

[Mike_F_]

After some years of use we stop and clean C3G124-48 and also replace internal bateries after doing that never more the switch boot up to operational code.

We think the system lost the firmware due to replacement of this battery (is this possible??)

The system goes only to this line and stops.

Enterasys C3-Series Boot Code...
SDRAM Circuit Test of 255MB
100%

How is possible to load again the firmware to the unit on this status.

Thanks in Advance

Solved: I had to flash few major version older fw so it flash "PROM". New PROM was also in 06.61.05.0009....Just flashing latest version is unsuficient.

Hello Mike, I have same problem, I am able to access boot menu and upload new FW by Xmodem. Problem is, that it success upload, update boot code and run into operational mode, but after reset it wont boot. I have to to same thing with short 28pin of memory every time to get unit boot. Any ideas?

Thanks for reply,

We know this method but on this case the procedure maybe will be "Empty Unit Firmware Loading" because is not possible to access boot menu, to use standard ID5605 method....
