| Component | Hot-Swap Capable? | Notes | | :--- | :--- | :--- | | | Yes (Redundant models) | If your Sone248uc has dual PSUs, they are almost certainly hot-swappable. You can pull one PSU while the other handles the load. | | Storage Drives (SAS/SATA/NVMe) | Yes | The backplane supports hot-swap. You can replace a failed drive without rebooting, provided you are using a RAID controller that supports it. | | Cooling Fans | Usually Yes | Most enterprise versions feature hot-swappable fan modules. A red LED indicates a failed fan; you can pull it out and insert a new one while running. | | CPU / RAM | No | Never attempt to hot-swap a CPU or RAM stick. This will cause instantaneous electrical arcing and destroy the motherboard. | | PCIe Expansion Cards | No (Standard) | Only specialized "PCIe hot-plug" motherboards support this. The standard Sone248uc does not. |
