Hi,

Unfortunately, this message is pretty explanatory - it points to an unrecoverable hardware problem, most probably with your memory.

You may want to open the router, dust it off if it has accumulated any dust over its time of operation, and if the RAM module can be removed, try to pull it out, dust off the memory slot, and reinstall the RAM.

If this operation does not help then I am afraid you will need to contact your support and have the RAM module or the entire router replaced.

Best regards,
Peter

The RAM in 2921 is Fixed onboard ECC memory—512 MB.

and have empty UDIMM expansion slots—1.

so I can not reinstall the RAM

what can do?

Hi Abubaker,

I am sorry to say that you most probably need to have the entire router replaced. This is a hardware issue that cannot be solved by some configuring around.

Best regards,

I had the same problem but was problem of electricity !!! The client connected the router to a UPS and the problem was there, we change to a direct electricity outlet and the problem was resolved !!
