Warning: The NAS supports replacing the redundant power supply unit

without turning off the server when redundant power supply mode is enabled.

However, you are strongly recommended to turn OFF the NAS before replacing the

power supply unit to reduce the risk of electric shock.

If you are using a single power (SP) rack mount NAS model, you can install a second

power supply unit to the NAS to upgrade the SP model to redundant power (RP)

model.
