Hi Greg,
Here is the method;
Using the CLI, follow these steps to enable HTTPS:
--------------------------------------------------------------------------------
Step 1 Enter show certificate summary to verify that the controller has generated a certificate:
>show certificate summary
Web Administration Certificate................. Locally Generated
Web Authentication Certificate................. Locally Generated
Certificate compatibility mode:................ off
Step 2 (Optional) If you need to generate a new certificate, enter this command:
>config certificate generate webadmin
After a few seconds the controller verifies that the certificate is generated:
Web Administration certificate has been generated
Step 3 Enter this command to enable HTTPS:
>config network secureweb enable
Step 4 Save the SSL certificate, key, and secure web password to NVRAM (non-volatile RAM) so your changes are retained across reboots:
>save config
Are you sure you want to save? (y/n) y
Configuration Saved!
Step 5 Reboot the controller:
>reset system
Are you sure you would like to reset the system? (y/n) y
System will now restart!
The controller reboots.

Hope this helps!
