The BMC web application is available via TLS-secured (https) access either directly through port 443 or indirectly through port 80 to 443. ACL rules are not applicable to prevent unsecured (http) access. A sample X.509 certificate which is a copy of the BMC, and EMA certificates are shipped along with the SBC shipment. The size of this certificate is 2,048 bits.
The BMC uses the common local certificate store of the SBC (used also for SIP/TLS) rather than having its own separate certificate store. Certificate with RSA keys up to 4,096 bits are supported. However, Sonus recommends using 2,048 bit certificates.
Enter the following URL in the browser to access the SBC BMC GUI:
where BMC IP address is the IP address of the BMC GUI.

Perform the same to select the SSL key.If you require the BMC to send a certificate chain of SSL certificates instead of its own server certificate only, you must import the intermediate CA and/or root CA certificates together with the SBC server certificate in one file. The file must contain all certificates in .pem format.
- Click Open. The selected SSL Certificate and the Privacy Key appears in the tab.
