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:
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 management module for more information).
4.
Replace the 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 119.
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
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
Management Module Command-Line Interface Reference
Guide
for information).
v
The BladeCenter unit blowers are correctly installed and operational.
If these procedures do not solve the problem, it is likely a problem with the blade
server. See “Power error messages” on page 120 and “Power problems” on page
122.
