ASA 5520 with DC power supply is only available with the default encryption license (ASA5500-ENCR-K8), which supports only DES encryption.
How can one order a strong encryption license (ASA5500-ENCR-K9) to use with ASA5520-DC-K8?
The ASA5500-ENCR-K9 license is not on the price list. Can one just ask it, free of cost, to http://www.cisco.com/go/license ?
Thanks for your help,
