Ah, ok. That is to connect the SEE Management Server to the Symantec Encryption Management Server, formerly known as the PGP Universal Server. It is for customers who are using both the SEE and PGP products, and allows the PGP server to sync recovery tokens to the SEE server. It is not a normal setup.
Do you have a Symantec Encryption Management Server in use in addition to the Symantec Endpoint Encryption Management Server?
The rebranding of PGP products into something with a very similar naming convention can cause some confusion. We see a lot of similar questions in support.
