I have new ASA5520. After configured and upgrade with ASA 8.0(3) image its works for few times (few times means after restarted several times). But now the error comes as "Booting system, Please wait..." nothing else appear.
Can anyone suggest what could be the problem. Thanks
Try loading the image on the ASA through rommon mode:
Here are the steps for loading image from rommon mode:
Step1 Power off the adaptive security appliance, and then power it on.
Step 2 During startup, press the Escape key when you are prompted to enter ROMMON mode.
Step3 In ROMMOM mode, define the interface settings to the adaptive security appliance, including the IP address, TFTP server address, gateway address, software image file, and port, as follows:
rommon #1> ADDRESS=10.132.44.177
rommon #2> SERVER=10.129.0.30
rommon #3> GATEWAY=10.132.44.1
rommon #4> IMAGE=f1/asa800-232-k8.bin
rommon #5> PORT=Ethernet0/0
Please make sure that the Tftp server is connected to the interface.
Step 5 To validate your settings, enter the set command.
rommon #6> set
Step 6 Ping the TFTP server by entering the ping server command.
rommon #7> ping server
Step 7 Load the software image by entering the tftp command.
rommon #8> tftp
Step 8 Reload the security appliance to run the new image.
rommon #9> reload
After the software image is successfully loaded, the security appliance automatically exits ROMMOM mode.
Here is the document to do the same:
If this does not work, then you would need to RMA the device.
