Use an HTTP session to download and install an SSL security
certificate file on the switch
If you use HTTPS instead of HTTP to access the main local browser user, you are not
required to obtain an SSL certificate. The security warning that might display in your
browser prompts you to confirm that the self-signed certificate of the switch is valid.
Once you do so, the browser warning might no longer display when you log in.
However, if you obtain an SSL security certificate from a certificate authority, you can
download and install the SSL security certificate through an HTTP session using your
web browser.
For an SSL security certificate, you must download two Privacy Enhanced Mail (PEM)
files to the switch:
•
SSL Trusted Root Certificate PEM File: The SSL trusted root certificate PEM file,
which must be in the format xxxxCERTxxxxx.pem.
•
SSL Server Certificate PEM File: The SSL server certificate PEM file (the key file),
which must be in the format xxxxKEYxxxxx.pem.
Before you can download and install an SSL security certificate, you must disable HTTPS
on the switch.
To disable HTTPS and use an HTTP session to download and install an SSL security
certificate file on the switch:
1. Launch a web browser.
2.
In the address field of your web browser, enter the IP address of the switch.
The login page displays.
3. Click the Main UI Login button.
