Hello all,

First time posting here so if my jargon or lingo is off stay with me. I am troubleshooting a Cisco 3800 series router for my company. I get alot of these in and while I am no expert by any means I can handle most of them. This one booted up and gave me this error:



Memory byte = 0xa000000008555554

Memory byte = 0x0000003455555554

Memory error location = 0xa00055d0


Lower 64K Memory test error !!!



Memory byte = 0xa000000008555554

Memory byte = 0x0000003455555554

Memory error location = 0xa00055d0


Lower 64K Memory test error !!!



So I replaced the SDRAM memory and it booted properly without issue. I thought I was out of the woods. I went to go through my normal procedures the console worked fine and I upgraded the Switch's IOS deleted the TXT configuration I used and write erased the rest to set it back to put on the shelf. I went back to the RTR to do the same deleted the TXT file and wr er and when I reloaded it froze up at this screen:

Proceed with reload? [confirm]

*May 28 19:08:33.359 GMT: %SYS-5-RELOAD: Reload requested by admin on console. Reload Reason: Reload Command.

From there it just froze. I tried to restart the router and I can't even get anything from the console port. I didn't plug anything into the console port that would burn it out so I'm not sure what would have caused this or how I go about fixing it. So I turn to yall what say you? If you need more info please let me know. Baud rate is 9600-8-N-1
 
the same console cable and hyperterminal program works with other routers its just specific to this one router
 
there isnt an error message... the error is that the console port just stopped working during a reboot and now i cant get anything not any garbled characters.
 
Sorry---I meant the previous error message with the bad memory, but it would have had to boot...sorry.

Being a 3800, do you have SmartNet? How old is it? It has a 90 warranty...
