Network connection problems

Use this information to diagnose and resolve network connection issues with the blade server.

To check for network connection problems, complete the following steps until the problem is solved:
  1. Make sure that:
    • The network cables are securely connected to the I/O module.
    • Power configuration of the BladeCenter unit supports the I/O-module configuration.
    • Installation of the I/O-module type is supported by the BladeCenter unit and blade server hardware.
    • The I/O modules for the network interface that is being used are installed in the correct BladeCenter I/O-module bays and are configured and operating correctly.
    • The settings in the I/O module are correct for the blade server (settings in the I/O module are specific to each blade server).
  2. Check for correct I/O-module operation; troubleshoot and replace the I/O module as indicated in the documentation for the I/O module.
  3. Check for correct management-module operation (see the documentation for your BladeCenter unit).
    Note
    Some BladeCenter unit types have several management-module components that might have to be tested or replaced (see the Installation Guide for your Advanced Management Module for more information).
  4. Replace the Advanced Management Module (see the documentation for your BladeCenter unit).

If these steps do not solve the problem, it is likely a problem with the blade server. See Network connection problems.
