Solving Shared Network Connection Problems - IBM Flex System p270 Compute Node Installation And Service Manual

2. Verify that power management is set correctly for your IBM Flex System Enterprise Chassis
configuration.
3. Verify whether the problem is being experienced on more than one compute node.
4. Perform a test of the failing function on a compute node that is known to be operational.
5. Try the compute node in a different bay.
6. Try a compute node that is known to be operational in the bay with the failing compute node.
7. Verify that the compute node and the monitor are powered on.
8. Check for network connection problems, as described in "Solving shared network connection
problems."
9. Check for power problems, as described in "Solving shared power problems" on page 484.

Solving shared network connection problems

Problems with shared resources might appear to be in the compute node, but might actually be a
problem in a IBM Flex System Enterprise Chassis network connection resource.
About this task
To check the general function of shared network connection resources, complete the following steps:
Procedure
1. Verify that the network cables are securely connected to the I/O module.
2. Verify that the power configuration of the IBM Flex System Enterprise Chassis supports the I/O
module configuration.
3. Verify that the installation of the I/O-module type is supported by the IBM Flex System Enterprise
Chassis and compute node hardware.
4. Verify that the I/O modules for the network interface are installed in the correct bays of the IBM Flex
System Enterprise Chassis.
5. Verify that the I/O modules for the network interface are configured correctly.
6. Verify that the settings in the I/O module are correct for the compute node. Some settings in the I/O
module are specifically for each compute node.
7. 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.
8. Verify that the management module is operating correctly.
9. Replace the management module.
