i have a new ASA 5520 with only factory default settings. I ran the commands below on the CLI as instructed for a Cisco document but i cannot access it via https://192.168.1.1/admin like it says i should be able to.
Step 1 
To identify the IP addresses from which the security appliance accepts HTTPS connections, enter the following command for each address or subnet:
hostname(config)# http source_IP_address mask source_interface
Step 2 To enable the HTTPS server, enter the following command:
hostname(config)# http server enable
Step 3 To specify the location of the ASDM image, enter the following command:
hostname(config)# asdm image disk0:/asdmfile
when i ran step 3 i got a printout of Device manager image set, but unable to find disk0: /asdmfile??
any help ?
