The default PowerTag Link gateway certificate is valid for 10 years starting from the first start-up (or last reset to factory) date and this certificate must be renewed periodically (at least a few days or weeks before its expiration date). For certificates provided by the certificate authority, check for the validity period and expiration date with the certificate provider authority.
