4 Troubleshooting
Introduction
This chapter presents troubleshooting information. Basic tips for start-up problems are presented, audio cues
and LED indicators are described and interpreted, and error messages (and how to retrieve them) are
described. In addition, problems that are associated with I/O functions and paths are discussed here.
Troubleshooting Methodology
WARNING Always disconnect the power cords and unplug telephone cables before removing
the server cover. Disconnect telephone cables to avoid exposure to shock hazard
from telephone ringing voltages. Disconnect the power cords to avoid exposure to
high energy levels that may cause burns when parts are short-circuited by metal
objects such as tools or jewelry.
CAUTION Do not operate the server for more than 2 minutes with any cover (including power supplies
and disk drives) removed. The covers also provide EMI containment and direct airflow within
the chassis. Depending on which cover or assembly is missing, the server may shutdown,
interrupting operations. In addition, damage to system components may result due to
overheating.
You can safely remove the front grill while the HP Server is running to remove and replace
hot-swap fans. The hot-swap power supplies and one hot-swap fan (accessible from the rear of
the chassis) can be replaced at any time. For any other service activity requiring access to
internal components, power down the server and observe all safety precautions.
The server was tested prior to shipping and should be in perfect working order. Failures encountered during
installation may be due to damage that occurred in transit. Reseating connectors may clear problems that
result from rough handling. If you are installing components or assemblies, compatibility problems or
incorrect installations may be the cause of problems. If you are installing components or assemblies, check
that items are correctly installed and that all connectors are fully engaged. If the unit will not power on,
check the power source before proceeding.
If a problem is encountered during initial operation, remove any add-in or optional components and retest the
server before continuing. Verify basic server operation before installing additional cards and configuring
software and hardware for your system requirements.
Troubleshooting is based on observation of server status indications and error messages, and by checking
system event logs. The system e-buzzer will provide an immediate indication of any start-up problems. LED
indicators can be observed on the front and rear of the server. Error messages are displayed on local and
remote consoles. System history (console, event, and history logs) are available through the management
processor, and can be accessed through the console. Additional information about troubleshooting can be
found in the hp Integrity cx2600 Operation and Maintenance Guide.
