Setting Up an SSL/TLS Certificate
Important: Legrand uses TLS instead of SSL 3.0 due to published security vulnerabilities in SSL 3.0. Make sure
your network infrastructure, such as LDAP and mail services, uses TLS rather than SSL 3.0.
Having an X.509 digital certificate ensures that both parties in an SSL/TLS connection are who they say they
are.
Besides, you can create or apply for a multi-domain certificate with subject alternative names.

To obtain a CA-signed certificate:
1. Create a Certificate Signing Request (CSR) on the Legrand PDU. See
Creating a CSR
(on page 185).
2. Submit it to a certificate authority (CA). After the CA processes the information in the CSR, it provides
you with a certificate.
3. Import the CA-signed certificate onto the Legrand PDU. See
Installing a CA-Signed Certificate
(on
page 187).
Note: If you are using a certificate that is part of a chain of certificates, each part of the chain is signed during
the validation process.

A CSR is not required in either scenario below:

Make the Legrand PDU create a
self-signed
certificate. See
Creating a Self-Signed Certificate
(on
page 187).

Appropriate, valid certificate and key files are already available, and you just need to import them. See
Installing or Downloading Existing Certificate and Key
(on page 188).
