ASA 5510, ASA 5520, ASA 5540, ASA 5550, and ASA 5580 are supported until ASA Version 9.1

CISCO noted that “The ASA 5510, ASA 5520, ASA 5540, ASA 5550, and ASA 5580 are not supported in this release or later. ASA Version 9.1 was the final release for these models”

I installed “asa917-9-k8.bin & asdm-752-153.bin” successfully.

If you boot with asa9.2(1) above, you will get in rommon mode.

now I don’t need to worry about java version mismatch.
