significantly increases the system’s serviceability and availability by providing the

ability to replace hard drives, fan units, and power supplies without service

disruption.

Power Supply Redundancy

The SPARC Enterprise T5120 and T5220 servers provide two hot-swappable power

supplies, enabling the system to continue operating should one of the power

supplies fail or if a power source fails.

Environmental Monitoring

The SPARC Enterprise T5120 and T5220 servers feature an environmental

monitoring subsystem that protects the server and its components against:

■ Extreme temperatures

■ Lack of adequate airflow through the system

■ Power supply failures

■ Hardware faults

Temperature sensors are located throughout the system to monitor the ambient

temperature of the system and internal components. The software and hardware

ensure that the temperatures within the enclosure do not exceed predetermined safe

operation ranges. If the temperature observed by a sensor falls below a low-

temperature threshold or rises above a high-temperature threshold, the monitoring

subsystem software lights the amber Service Required LEDs on the front and back

panel. If the temperature condition persists and reaches a critical threshold, the

system initiates a graceful system shutdown. In the event of a failure of the system

controller, backup sensors protect the system from serious damage, by initiating a

forced hardware shutdown. Required LEDs remain lit after an automatic system

shutdown to aid in problem diagnosis.

The power subsystem is monitored in a similar fashion by monitoring power

supplies and reporting any fault in the front and rear panel LEDs.

Support for RAID Storage Configurations

You can set up hardware RAID 1 (mirroring) and hardware RAID 0 (striping)

configurations for any pair of internal hard drives, providing a high-performance

solution for hard drive mirroring.
