c.Replace the remaining processor with a known functional processor. If the problem is resolved after you restart the server, a fault exists with one or more of the original processors. Install each processor and its associated PPM (if applicable) one by one, restarting each time, to find the faulty processor or processors. Be sure the processor configurations at each step are compatible with the server requirements.

System open circuits and short circuits

Action:

CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

1.Check the server LEDs to see if any statuses indicate the source of the problem. For LED information, refer to the server documentation.

2.Remove all power sources to the server.

3.Be sure no loose connections (on page 15) exist in the area.

4.Be sure each component in the area is working. Refer to the section for each component in this guide.

If you cannot determine the problem by checking the specific area, perform each of the following actions. Restart the server after each action to see if the problem has been corrected.

•Reseat all I/O expansion boards.

•Be sure no loose connections (on page 15) exist in the rest of the server, particularly with the cables that connect to the system board.

•Be sure no foreign material exists, such as screws, bits, or slot bracket blanks, that may be short circuiting components.

External device problems

Video problems

Screen is blank for more than 60 seconds after you power up the server

Action:

1.Be sure the monitor power cord is plugged into a working grounded (earthed) AC outlet.

2.Power up the monitor and be sure the monitor light is on, indicating that the monitor is receiving power.

3.Be sure the monitor is cabled to the intended server or KVM connection.

4.Be sure no loose connections (on page 15) exist.

•For rack-mounted servers, check the cables to the KVM switch and be sure the switch is correctly set for the server. You may need to connect the monitor directly to the server to be sure the KVM switch has not failed.

•For tower model servers, check the cable connection from the monitor to the server, and then from the server to the power outlet.

5.Press any key, or type the password, and wait a few moments for the screen to activate to be sure the energy saver feature is not in effect.

6.Be sure the video driver is current. Refer to the third-party video adapter documentation for driver requirements.

ProLight Server specifications

The HP ProLiant server series is designed to deliver exceptional performance, scalability, and reliability for a variety of workloads, making it a popular choice among businesses of all sizes. Known for its robust architecture, the ProLiant series integrates cutting-edge technologies to support critical applications, virtualization, and cloud computing.

One of the defining features of HP ProLiant servers is their advanced management capabilities, facilitated by HP Integrated Lights-Out (iLO) technology. This embedded management tool offers remote access and monitoring capabilities, enabling IT administrators to oversee servers even when they are powered down. iLO provides essential features like firmware lifecycle management, power consumption monitoring, and system health checks, all of which simplify management and enhance uptime.

HP ProLiant servers leverage Intel's latest Xeon processors, which deliver impressive processing power and energy efficiency. The architecture supports multi-core processing, allowing for greater parallelism and improved operational efficiency. Furthermore, the series supports various memory configurations, with options for scalable and high-speed memory that can significantly enhance performance in memory-intensive applications.

Storage is another strength of the HP ProLiant series. The servers provide a range of storage options, including HDDs and SSDs, which enable organizations to configure systems to meet their performance and capacity requirements. HP’s Smart Array technology allows for advanced RAID capabilities, providing added data protection and redundancy, ensuring that critical information remains secure even during hardware failures.

HP ProLiant servers also focus on security, featuring built-in security technologies to protect against potential threats. Technologies such as silicon root of trust, secure boot, and firmware validation help safeguard server integrity from the ground up.

Scalability is essential for growing businesses, and the ProLiant series is designed to accommodate increasing workloads efficiently. Its modular architecture allows for seamless upgrades, ensuring that organizations can expand their infrastructure as needed without extensive downtime or resource expenditure.

In conclusion, the HP ProLiant server series blends performance, management, security, and scalability, making it a reliable choice for enterprise IT environments. With its robust features, advanced technologies, and focus on security and manageability, HP ProLiant servers provide businesses with the capability to meet their evolving IT demands effectively.
