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.
Results
If these steps do not resolve the problem, it is probably a problem with the compute node. See
"Connectivity problems" on page 421 for more information.
Solving shared power 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 power component.
About this task
To check the general function of shared power resources, complete the following steps:
Procedure
1. Verify that the LEDs on all the power modules of the IBM Flex System Enterprise Chassis are lit.
2. Verify that power is being supplied to the IBM Flex System Enterprise Chassis.
3. Verify that the installation of the compute node type is supported by the IBM Flex System Enterprise
Chassis.
4. Verify that the power configuration of the IBM Flex System Enterprise Chassis supports the bay
where your compute node is installed.
5. Verify that the power management configuration and status of the IBM Flex System Enterprise
Chassis support compute node operation.
See the information center for your management module or the Management Module User's Guide or
the Management Module Command-Line Interface Reference Guide for more information.
