2.6Power-On Self Test (POST)

The BIOS indicates the current testing phase during POST by writing a hex code to the Enhanced Diagnostic LEDs, located on the rear of the server main board and visible through the back of the chassis.

If errors are encountered, error messages or codes will either be displayed to the video screen, or if an error has occurred prior to video initialization, errors will be reported through a series of audible beep codes. POST errors are logged in to the System Event Log (SEL).

During the power-on self test (POST), the server may indicate a system fault by:

■Displaying error codes and messages at the display screen

■Beeping the speaker in a coded sequence

■Illuminating the POST LEDs, visible from the rear panel, in a coded fashion

2.6.1POST Screen Messages

During POST, if an error is detected, the BIOS displays an error code and message to the screen. The tables in this section describe the standard and extended POST error codes and their associated messages. The BIOS prompts the user to press a key in case of serious errors. Some of the error messages are preceded by the string “Error” to highlight the fact that the system may be malfunctioning. All POST errors and warnings are logged in the System Event Log (SEL) unless it is full.

Note – All POST errors are logged to the SEL, which is capable of holding approximately 3200 entries. After the SEL is full, no further errors are logged. The SEL can be cleared using the SSU or the BIOS setup. The SEL is automatically cleared after running the PCT.

Table 2-9and Table 2-10contain the POST error messages and error codes.

5310 NAS specifications

Sun Microsystems, known for its innovative computing solutions, launched the Sun 5310 Network Attached Storage (NAS) system, which marked a significant advancement in the realm of storage solutions in the early 2000s. The 5310 NAS was designed to provide high-performance, reliable, and scalable storage tailored for enterprise environments.

One of the standout features of the Sun 5310 NAS is its file-serving capabilities, which support multiple protocols, notably NFS (Network File System) and CIFS (Common Internet File System). This dual-protocol support allowed organizations to seamlessly integrate the NAS into diverse IT ecosystems, facilitating interoperability between UNIX, Linux, and Windows systems. The enhanced file-sharing capabilities made it an ideal solution for businesses with mixed operating environments.

The Sun 5310 NAS incorporates cutting-edge technologies to ensure high availability and data integrity. The system utilized a RAID (Redundant Array of Independent Disks) technology, providing various RAID levels to protect against data loss while optimizing performance. Additionally, the device featured hot-swappable drives, enabling maintenance and upgrades with minimal downtime, a crucial factor for business continuity.

Equipped with advanced management software, the Sun 5310 NAS offered users an intuitive interface for monitoring storage health and performance. This software included comprehensive reporting functionalities that allowed IT administrators to oversee usage patterns and capacity planning efficiently.

Scalability was another defining characteristic of the Sun 5310 NAS. The system could easily expand with additional storage modules, accommodating the growing needs of an organization without the necessity for complete system overhauls. This flexibility ensured that businesses could adapt their storage solutions to meet evolving data storage needs without incurring significant costs or disruptions.

In terms of performance, the Sun 5310 NAS featured high I/O throughput achieved through its robust hardware architecture and optimized file serving capabilities. This performance baseline was crucial for organizations that relied on heavy data workloads and required rapid access to information.

In summary, the Sun 5310 NAS from Sun Microsystems embodied a forward-thinking approach to network storage, blending reliability, scalability, and multi-protocol support. Its user-friendly management software, combined with the robustness of RAID technology and hot-swappable drives, made it a preferred choice for enterprises looking to streamline their storage infrastructure while safeguarding critical data.
