■POST LEDs: To help diagnose POST failures, a set of four bi-color diagnostic LEDs is located on the back edge of the baseboard. Each of the four LEDs can have one of four states:

Off, Green, Red, or Amber. During the POST process, each light sequence represents a specific Port-80 POST code. If a system should hang during POST, the diagnostic LEDs present the last test executed before the hang. When reading the lights, the LEDs should be observed from the back of the system. The most significant bit (MSB) is the first LED on the left, and the least significant bit (LSB) is the last LED on the right.

See “POST Progress Code LED Indicators” on page 2-30for details regarding the POST LED display.

■CPU Fault LEDs: A fault indicator LED is located next to each of the processor sockets. If the server Baseboard Management Controller (BMC) detects a fault in any processor, the corresponding LED illuminates.

■Memory Fault LEDs: A fault indicator LED is located next to each of the DIMM sockets. If the BMC detects a fault in a given DIMM, the corresponding LED illuminates.

One LED for each DIMM is illuminated if that DIMM has an uncorrectable or multi-bit memory error. The LEDs maintain the same state across power switch, power down, or loss of AC power.

■Fan Fault LEDs: Depending on the server model, the fan header may include a fan fault LED. If the BMC detects a fan fault, the LED illuminates. If the fan fault LED is lit, the entire fan module must be replaced.

■System Status LED: Indicates functional status of the server board. Glows green when all systems are operating normally. Glows amber when one or more systems are in a fault status. This LED mirrors the function of the system status LED on the front panel.

See Table 2-7 on page 2-18for a description of the LED states.

■+5V Standby LED. This green LED is on when the server is plugged into AC power, whether or not the server is actually powered on. AC power is applied to the system as soon as the AC cord is plugged into the power supply.

■System ID LED. This blue LED can be illuminated to identify the server when it is part of a large stack of servers. See “System ID LEDs” on page 2-23for details.

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.
