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

Hi, you probably doesn't read carefully what Mike F. wrote in his post. Return and read again 🙂

With a cable we use oscilloscope prove make connection between ground on any point at the board and the pin 28 of U19 Intel JS28F128J3D75 flash memory this pin is A1 address bus pin, this make the Freescale processor jump to some instruction with result like this.

Thanks for your really quick response@feldsam
But I don´t know how to do that.
I have open a serial connection to the switch and the only message I can see is this:
Enterasys C3-Series Boot Code...
SDRAM Circuit Test of 255MB
100%

Then it does nothing.

hello, as I wrote, you need to flash FW version 06.61.05.0009 which contains PROM also.

I have the same issue. Could you help me with that?

Welcome to the Hub Feldsam....great to have you join us.

Better yet, great that you found a resolution to your problem. Thanks for letting the Community know.

I noticed that this thread pre-dates GTAC Knowledge, so thought I'd throw a link in an applicable article for those in the future that read this thread.
