Lenovo BladeCenter HX5 1909 Problem Determination And Service Manual Download Page 288

Page: 288 / 313

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 chassis).

If these steps do not solve the problem, it is likely a problem with the blade server. See “Network connection
problems” on page 259.

Power problems

Use this information to diagnose and solve 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 chassis.

• The BladeCenter chassis support installation of the blade server type.

• The BladeCenter chassis has the correct power configuration to operate the blade server bay where the

blade server is installed (see the documentation for your BladeCenter chassis).

• The BladeCenter chassis 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).

• The power LED on the blade server flashes slowly before you press the power button.

Note:

While the service processor in the blade server is initializing and synchronizing with the

management module, the power LED flashes rapidly, and the power button on the blade server does not
respond. This process can take approximately 2 minutes after the blade server has been installed.

• The BladeCenter chassis 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 261 and “Power problems” on page 265.

Video problems

Use this information to diagnose and solve video issues.

To check for video problems, complete the following steps until the problem is solved:

Step 1. Make sure that:

• Both the blade server and the monitor are turned on, and the monitor brightness and contrast

controls are correctly adjusted.

• The keyboard/video/mouse select button LED on the front of the blade server is lit, indicating

that the blade server is connected to the shared BladeCenter monitor.

• The video cable is securely connected to the BladeCenter advanced management module. Non-

IBM monitor cables might cause unpredictable problems.

• The monitor works with another blade server.
• Some IBM monitors have their own self-tests. If you suspect a problem with the monitor, see the

information that comes with the monitor for instructions for adjusting and testing the monitor. If
the monitor self-tests show that the monitor is working correctly, consider the location of the
monitor. Magnetic fields around other devices (such as transformers, appliances, fluorescent
lights, and other monitors) can cause screen jitter or wavy, unreadable, rolling, or distorted
screen images. If this happens, turn off the monitor.
