Abstract
The Remote Supervisor Adapter II, BMC, and BladeCenter Management Module use a variety of TCP/IP ports for communication. This technote lists them and indicates which ones the administrator can and cannot change. You need to ensure that your network (firewalls and routers) allows communications through these ports for the adapter and Management Module to function properly.
