Hot-Pluggable and Hot-Swappable Components
SPARC Enterprise T5120 and T5220 server hardware is designed to support
hot-plugging of the chassis-mounted hard drives, and hot-swapping of fan units, and
power supplies. By using the proper software commands, you can install or remove
these components while the system is running. Hot-swap and hot-plug technology
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.
