If event monitoring is enabled, and if event notification is configured, the software also issues one or both of the following critical problem notifications:

■If one power supply shuts down, the storage management software will display a Needs Attention status in the Array Management Window.

■If both power supplies shut down, the module will shut down, and the storage management software will display a Not Responding status in the Array Management Window.

Use the following procedure to resume normal operation after a power supply shutdown.

Figure 3-16 on page 3-28shows the locations of the power supply switches.

Caution – Risk of damage from overheating. Power supplies automatically shut down when the air temperature inside the cabinet reaches 70° C (158° F). If the power supplies have shut down, immediately remove all cabinet panels to help cool the cabinet air temperature and prevent damage to the modules.

1.Remove the cover.

2.If needed, turn off the alarm.

3.Did you use the procedure “Troubleshooting the Module” on page 3-22to identify an overheating problem?

■Yes - Go to step 4.

■No - Perform the procedure “Troubleshooting the Module” on page 3-22to verify that the power supplies have shut down because of an overheating problem. When finished, go to step 4.

4.Stop I/O activity to the module and all attached modules.

5.To alleviate the overheating problem, perform any or all of the following cooling measures:

a. Immediately removing all panels from the cabinet. b. Using external fans to cool the area.

c. Shut down the power to the modules in the cabinet, using the procedure described in “Turning Off Power for a Planned Shutdown” on page 3-11.

6.Wait for the air temperature in and around the module to cool.

After the temperature inside the power supplies cools to below 70° C (158° F), the module is capable of a power-up recovery without operator intervention. After the air has cooled, the power supplies should turn on automatically. If the power supplies restart automatically, the controllers reset and return to normal operation.

7.Did the power supplies restart automatically?

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.
