One of the tasks you should complete during the installation of the Cisco UCS Manager is configuring the Fabric Interconnects with a trusted SSL certificate. The procedure is straight forward, and only needs to be completed once, since the two Fabric Interconnects are clustered and the configuration is replicated between the two devices. In my example I’m using a Windows Server 2008 R2 Certificate Authority, but any CA should work, but the steps will vary a bit.
1. Login to your Windows CA web services site (https://yourCA/certsrv) and click on Download a CA certificate, certificate chain, or CRL.
2. On the next screen select the current root certificate, Base 64 encoding, and then click on Download CA certificate chain.
