4. Verify that the monitor works with another blade server.
5. Move the device and the monitor at least 305 mm (12 in.) apart, then turn on the
monitor.
Attention: Moving a color monitor while it is turned on might cause screen
discoloration.
If the monitor self-tests show that the monitor is working correctly, the location of the
monitor might be affecting its operation. 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.
6. Verify that the management module is operating correctly.
See the documentation for your Bull Blade Chassis - Enterprise.
Some Bull Blade Chassis - Enterprise types have several management-module
components that you might test or replace.
See the
Installation Guide for your management module for more information.
7. Replace the monitor cable, if applicable.
8. Replace the monitor.
9. Replace the management module.
See the
Problem Determination and Service Guide or the Hardware Maintenance
Manual and Troubleshooting Guide for your Bull Blade Chassis - Enterprise.
If these steps do not resolve the problem, it is likely a problem with the blade server. See
“ Monitor or video problems “, on page 162 for more information.
2.15 Solving undetermined problems
When you are diagnosing a problem in the
Escala BL460
blade server, you must determine
whether the problem is in the blade server or in the Bull Blade Chassis - Enterprise.
•
If all of the blade servers have the same symptom, it is probably a Blade Chassis -
Enterprise problem; for more information, See the Hardware Maintenance Manual and
Troubleshooting Guide or Problem Determination and ServiceGuide for your Bull Blade
Chassis - Enterprise.
• If the Bull Blade Chassis - Enterprise contains more than one blade server and only one
of the blade servers has the problem, troubleshoot the blade server that has the
problem.
Check the LEDs on all the power supplies of the Bull Blade Chassis - Enterprise where the
blade server is installed. If the LEDs indicate that the power supplies are working correctly,
and reseating the blade server does not correct the problem, complete the following steps:
1. Make sure that the control panel connector is correctly seated on the system board.
See “ System-board connectors ” on page 12 for the location of the connector.
