14.4.2 Verifying a Certificate

Before you import a certificate into the WiMAX Modem, you should verify that you have the
correct certificate. This is especially true of trusted certificates since the WiMAX Modem also
trusts any valid certificate signed by any of the imported trusted certificates.

The following procedure describes how to check a certificate's fingerprint to verify that you
have the actual certificate.
1 Browse to where you have the certificate saved on your computer.
2 Make sure that the certificate has a ".cer" or ".crt" file name extension. (On some Linux
distributions, the file extension may be ".der".)
