Installing a CA-Signed Certificate
To get a certificate from a certificate authority (CA), first create a CSR and send it to the CA. See
Creating a
CSR
(on page 185).
After receiving the CA-signed certificate, install it onto the Legrand PDU.
To install the CA-signed certificate:
1. Choose Device Settings > Security > SSL Certificate.
2. Click
to navigate to the CA-signed certificate file.
3. Click Upload to install it.
4. To verify whether the certificate has been installed successfully, check the data shown in the Active SSL
Certificate section.
Creating a Self-Signed Certificate
When appropriate certificate and key files for the Legrand PDU are unavailable, the alternative, other than
submitting a CSR to the CA, is to generate a self-signed certificate.
Note that you must enter information in the fields showing the message 'required.'
To create and install a self-signed certificate:
1. Choose Device Settings > Security > SSL Certificate.
2. Enter
information.

Only 2048 is available now.
Self-Sign
Ensure this checkbox is selected, which indicates that you are
creating a self-signed certificate.
Validity in days
This field appears after the Self Sign checkbox is selected.
Type the number of days for which the self-signed certificate will be
valid.
A password is not required for a self-signed certificate so the Challenge and Confirm Challenge fields
disappear.
3. Click Create New SSL Key to create both the self-signed certificate and private key. This may take
several minutes to complete.
