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).
Step 8. 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 “Removable-media
drive problems” on page 200 or “Universal Serial Bus (USB) port problems” on page 203.
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:
Step 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).
Step 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.
Step 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).
Step 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 193.
Power problems
Use this information to diagnose and resolve power issues with the blade server.
To check for power problems, make sure that:
• The LEDs on all the BladeCenter power modules are lit.
• Power is being supplied to the BladeCenter unit.
• The BladeCenter unit support installation of the blade server type.
• 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).
• 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).
• 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).
