Abstract
The management processors integrated in System x, BladeCenter and Flex System servers 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. The management processors covered are:
* Chassis Management Module (CMM)
* Integrated Management Module II (IMM2)
* Integrated Management Module (IMM)
* BladeCenter Advanced Management Module (AMM)
* BladeCenter Management Module (MM)
* Remote Supervisor Adapter II (RSA II)
* Baseboard Management Controller (BMC)
