APPENDIX A: UPLOADING SSL SECURITY CERTIFICATES
A.1.6 UPLOADING THE .PEM FOR PLUS GATEWAY WEB UI
To upload the .PEM for the Plus Gateway Web UI, open the Settings / Services menu as shown in Figure A-6:
1. Click on the Choose file button next to the Upload Certificate File field.
If the file format is correct (see instructions below), then your certificate can be used immediately.
You can open Web UI with HTTPS and verify that your SSL certificate is used.
If there is a problem with the certificate and Web UI doesn't open with HTTPS, open it again using HTTP and replace
the .PEM file again.
NOTE: On older F4 platform gateways, the .PEM's total file size must be less than 4KB, regardless of the used
private key size. If you exceed this file size, the unit won't be able to use the certificate, and the Web UI won't
load over HTTPS.
Also note that using a very large private key can cause Web UI slowdown. The newer F7 platform units, however,
don't have this limitation.
