If these steps do not resolve the problem, it is likely a problem with the blade server. See “Universal
Serial Bus (USB) port problems” on page 213 for more information.
Solving shared network connection problems
Problems with BladeCenter shared resources might appear to be in the blade server, but might actually be
a problem in a BladeCenter unit network connection resource.
To check the general function of shared BladeCenter network connection resources, perform the following
procedure.
1. Verify that the network cables are securely connected to the I/O module.
2. Verify that the network cables are securely connected to the I/O module.
3. Verify that the power configuration of the BladeCenter unit supports the I/O module configuration.
4. Verify that the installation of the I/O-module type is supported by the BladeCenter unit and blade
server hardware.
5. Verify that the I/O modules for the network interface are installed in the correct BladeCenter bays.
6. Verify that the I/O modules for the network interface are configured correctly.
7. Verify that the settings in the I/O module are correct for the blade server. Some settings in the I/O
module are specifically for each blade server.
8. Verify that the I/O modules for the network interface are operating correctly.
Troubleshoot and replace the I/O module as indicated in the documentation for the I/O module.
9. Verify that the management module is operating correctly.
See the online information center or the Problem Determination and Service Guide or the Hardware
Maintenance Manual and Troubleshooting Guide for your BladeCenter unit.
Some BladeCenter unit types have several management-module components that you might test or
replace. See the online information or the Installation Guide for your management module for more
information
10. Replace the management module.
See the online information center or the Problem Determination and Service Guide or the Hardware
Maintenance Manual and Troubleshooting Guide for your BladeCenter unit.
If these steps do not resolve the problem, it is likely a problem with the blade server. See “Network
connection problems” on page 194 for more information.
Solving shared power problems
Problems with BladeCenter shared resources might appear to be in the blade server, but might actually be
