How does a smoke alarm work?
The most common type of smoke detector uses a tiny amount of a radioactive element called americium to inject electric charges into the air. In the absence of smoke, these electric charges attach themselves to individual air molecules and the resulting ions (electrically charged molecules) move rather easily through the air. However, if there is smoke present in the air, the electric charges attached themselves to the smoke particles and the resulting charged smoke particles don't move easily through the air. The smoke detector measures how easily the charged items it produces move through the air. If these items move easily, then the air is clean. However if they don't move easily, the air contains smoke and the detector signals danger.

Precautions while using Power Supply
Pre servicing procedure
Turn off the server and all the peripherals connected to it.
Unplug all cables from the power outlets to avoid exposure to high energy levels that may cause burns when parts are short circuited by metal objects such as tools or jewelry.
During disassembly, label each cable as you remove it, noting its position and routing.
This will make the replacement of the cables much easier, and will ensure that the cables are rerouted properly to protect the cables.
Keep all screws with the units removed. The screws used in the server may be of different thread sizes and lengths; using the wrong screw in a component could damage the unit.
If server is installed in a rack, remove server and place it on a flat surface.
Disconnect telecommunication cables to avoid exposure to shock hazard from ringing voltages.
Follow the ESD precautions when handling a server component.
