meter web server
HTTP Allows non-secure access and unencrypted communications between
the client computer and the meter web server
HTTPS Allows only secure access and encrypted communications between
the client computer and the meter web server
HTTPS With HTTP
Redirect Redirects all HTTP requests to use the HTTPS web protocol.
You can change the default Assigned Port Numbers for HTTP and HTTPS . This
requires appending the changed port number for HTTP or HTTPS access to the
meter’s webpages. For example, <meter IP address>:<changed http or https port
number>.
Secure website indicator
A secure website displays a visible indicator such as a lock icon on the web
browser.
The web address prefix https:// also indicates that the website is secure.
Web browsers typically prompt or display a message to warn you if a website you
are trying to access is not secure. For https connections, this indicates that the
website’s SSL certificate is not configured properly or is missing.
Default SSL certificate and webpages security
The meter web server protocol is factory-set to HTTPS with HTTP Redirect.
The meter ships from the factory with a self-signed certificate installed, and is set
to to use HTTPS protocol when accessing the webpages. Because the SSL
certificate is self-signed and not signed by a trusted Certificate Authority (CA),
almost all browsers will flag the webpages as unsafe.
• If your meter is accessible only inside a secure network, you can add a
security exception to override how the browser identifies the webpages.
• If your meter is outside a secure network, you can install a SSL certificate
issued by a CA.
Uploading a custom SSL certificate
You can upload a custom SSL certificate through the meter webpages.
Your meter supports .pem certificate file formats.
1. Use a browser to log in to your meter.
2. Navigate to Setup > HTTPS .
3. Click Upload certificate .
4. Browse to where you saved the custom certificate, select it then click Open .
The certificate is uploaded to the meter, then the browser session is restarted.
