To check for network connection problems, complete the following steps until the
problem is solved:
1.
Make sure that:
v
The network cables are securely connected to the I/O module.
v
Power configuration of the BladeCenter unit supports the I/O-module
configuration.
v
Installation of the I/O-module type is supported by the BladeCenter unit and
blade server hardware.
v
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.
v
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” on page 171.
Power problems
Use this information to diagnose and resolve power issues with the blade server.
To check for power problems, make sure that:
v
The LEDs on all the BladeCenter power modules are lit.
v Power is being supplied to the BladeCenter unit.
v
The BladeCenter unit support installation of the blade server type.
v
The BladeCenter unit has the correct power configuration to operate the blade
server bay where the blade server is installed (see the documentation for your
BladeCenter unit).
v
The BladeCenter unit power-management configuration and status support
blade server operation (see the
Advanced Management Module User's Guide or the
Management Module Command-Line Interface Reference Guide for information).
v
Local power control for the blade server is correctly set (see the Management
Module User's Guide or the Advanced Management Module Command-Line Interface
Reference Guide for information).
v The power-on LED on the blade server flashes slowly before you press the
power-control button.
Note:
While the service processor in the blade server is initializing and
synchronizing with the management module, the power-on LED flashes rapidly,
and the power-control button on the blade server does not respond. This process
can take approximately two minutes after the blade server has been installed.
v
The BladeCenter unit blowers are correctly installed and operational.
