LABEL DESCRIPTION
PKI Storage Space

This bar displays the percentage of the NXC’s PKI storage space that is currently in use. When
the storage space is almost full, you should consider deleting expired or unnecessary
certificates before adding more certificates.
My Certificate Setting
Add Click this to go to the screen where you can have the NXC generate a certificate or a
certification request.
Edit Double-click an entry or select it and click Edit to open a screen with an in-depth list of
information about the certificate.
Remove The NXC keeps all of your certificates unless you specifically delete them. Uploading a new
firmware or default configuration file does not delete your certificates. To remove an entry,
select it and click Remove. The NXC confirms you want to remove it before doing so.
Subsequent certificates move up by one when you take this action.
Object References You cannot delete certificates that any of the NXC’s features are configured to use. Select an
entry and click Object References to open a screen that shows which settings use the entry.

each certificate a unique name.
