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

yes, correct. I use for this cheap multimeter in current mode. https://www.homepower.com/sites/default/files/uploads/3_cheap-meter.jpg

So, you mean, connect the power and with a wire touch the box, and that spot 28 of the chip : E28F128J3A ??
It is safe for the electrical installation? I don´t care about the switch

hmm, probably try that empty space for chip E28F128J3A, spot 28.
