Abstract

The systems management processors integrated in System x, Flex System, and BladeCenter servers use a variety of TCP/IP ports for communication. This document 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 management processor to function properly.

Change History

Changes in the July 13 update:

  • Added ports 5985 and 5986 to Table 4 - IMM2 section

Introduction

The systems management processors (also known as service processors) integrated in System x, Flex System, and BladeCenter servers use a variety of TCP/IP ports for communication. This document 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 management processor to function properly.

The management processors covered are:

  • Chassis Management Module (CMM and CMM2)
  • Integrated Management Module II (IMM2 and IMM2.1)
  • Integrated Management Module (IMM)
  • BladeCenter Advanced Management Module (AMM)
  • BladeCenter Management Module (MM)
  • Remote Supervisor Adapter II (RSA II)
  • Baseboard Management Controller (BMC)
