Digital Certificate for SSL communication Managing multiple certificates 2 The multiple certificate feature allows you to manage each certificate that you have installed using Web Based Management. After installing certificates, you can view what certificates are installed from the Certificate page and then view each certificate's content, delete or export the certificate. For information on how to access the Certificate page, see Digital Certificate Installation uu page 4. 2  For Printer models The Brother machine allows you to store up to three self-signed certificates or up to three certificates issued by a CA. You can use the stored certificates for using the HTTPS/IPPS protocol or IEEE 802.1x authentication.  For DCP and MFC models The Brother machine allows you to store up to four self-signed certificates or up to four certificates issued by a CA. You can use the stored certificates for using the HTTPS/IPPS protocol, IEEE 802.1x authentication or a Signed PDF. You can also store up to four CA certificates for using IEEE 802.1x authentication and SSL for SMTP/POP3. We recommend you store one certificate less and keep the last free to deal with certificate expiration. For example, if you want to store a CA certificate, store three certificates and leave one storage as a backup. In the case of re-issuing the certificate, such as when the certificate is expired, you can import a new certificate to the backup and then you can delete the expired certificate, to avoid configuration failure. Note • When you use HTTPS/IPPS, IEEE 802.1x or Signed PDF (for DCP and MFC models), you must choose which certificate you are using. • When you use SSL for SMTP/POP3 communications (for DCP and MFC models), you do not have to choose the certificate. The necessary certificate will be chosen automatically. 19
