Site Recovery Manager Server instances use several network ports to communicate with each other, with client plug-ins, with Platform Services Controller, and with vCenter Server. If any of these ports are in use by other applications or are blocked on your network, you must reconfigure Site Recovery Manager to use different ports.

Site Recovery Manager uses default network ports for intrasite communication between hosts at a single site and intersite communication between hosts at the protected and recovery sites. You can change these defaults when you install Site Recovery Manager. Beyond these standard ports, you must also meet network requirements of your particular array-based replication provider.

You can change the network ports from the defaults when you first install Site Recovery Manager. You cannot change the network ports after you have installed Site Recovery Manager.
