LABEL DESCRIPTION
PKI Storage
Space in Use This bar displays the percentage of the NWA’s PKI storage space that is
currently in use. When you are using 80% or less of the storage space,
the bar is green. When the amount of space used is over 80%, the bar
is red. When the bar is red, you should consider deleting expired or
unnecessary certificates before adding more certificates.
Replace This button displays when the NWA has the factory default certificate.
The factory default certificate is common to all NWAs that use
certificates. ZyXEL recommends that you use this button to replace the
factory default certificate with one that uses your NWA's MAC address.

listed in alphabetical order.

recommended that you give each certificate a unique name.

issues a certificate. Use the
My Certificate Import screen to import
the certificate and replace the request.

certification authority, such as a common name, organizational unit or
