Feb 5th, 2010


When I try to boot my ASA5550 it hangs at "booting system please wait". I have tried to reseting the ASA but this doesn't help. Can anyone give me an idea of what to try as I cannot get to the rommon.


I have this problem too.

Thanks Kusankar,

The problem it that I cannot get into rommon when I press the esc key. The ASA just dosn't responds.

I would try another computer and console in and try the same and if you cannot issue a break using "esc" key then, the unit may be bad and you may have to file an RMA to get it replaced with you have valid smartnet.

Hallo Poonguzhali

We bought ASA5550 with similar issue.

Can you tell me what's RMA procedure and how long it takes?

I get the same problem after upgrading three ASA 5540s from 1GB to 2GB of RAM in order to load 8.3 code.

None of the firewalls will boot.

problem solved !!!!!

it can be a RAM problem, as was the case for me. the electric interruption has burned  RAM memory.I removed it and the firewall is running normally with the remaining RAM.

I had the same symptom from a different cause.  My ASA was hung on "booting system, please wait".  I popped in some new RAM, and it came up.  +5 for you MOUBTAHIJ.
