Managing multiple certificates
7
This 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
Configure Certificate page and then view each certificate's content, delete or export the certificate. For
information on how to access the Configure Certificate page, see Configure certificate using Web Based
Management on page 61. The Brother machine allows you to store up to three self-signed certificates or up
to four certificates issued by a CA. You can use the stored certificates for using the HTTP/IPPS protocol or
IEEE 802.1x authentication.
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 HTTP/IPPS protocol or IEEE 802.1x, you must choose which certificate you are using.
