Managing certificates and other settings

Managing certificates and other settings
Note: This feature is available only in some printer models.
The Certificate Management menu is used for configuring printers to utilize certificates for establishing SSL, IPSec, and
802.1x connections. Additionally, devices utilize certificates for LDAP over SSL authentication and address book look-
ups.
Certificates are used by network devices to securely identify other devices. Certificate Authorities (CA) are trusted
locations established on the network that are required in secure environments. Otherwise, the default device certificate
is used to identify devices on the network.
The process for creating a CA-signed certificate on a device consists of the following activities:
1
Loading of the CA certificate for a certificate authority into the device
2
Creating a Certificate Signing Request (CSR) to obtain a CA-signed device certificate
3
Generating a CA-signed certificate using the CSR by the CA administrator
4
Loading of the CA-signed certificate into the device

Installing a Certificate Authority certificate on the device

Note: This feature is available only in network printers or in printers connected to print servers.
The Certificate Authority (CA) certificate is needed so that the printer can trust and validate the credentials of another
system on the network. Without a CA certificate, the printer cannot determine whether to trust the certificate that is
presented by the system trying to create the secure connection.
Start with the certificate file (.pem format) for the CA that you want to utilize. An example of how to create this file is
provided in "Appendix A: CA file creation" on page
