Access Underfloor Plenum and Observe Cabling

What happens here

To run the cables, access to the underfloor plenum is required. The electrician demonstrates using a suction cup floor remover to lift the raised floor tiles. This reveals the underfloor area, which in a data center is often a 'plenum' space used for air circulation and cable management. It's crucial to use plenum-rated MC (Metal Clad) cable in this space, as specified by codes, to prevent the spread of fire and toxic fumes in case of a fire.

Goal: Gain access to the underfloor plenum for cable routing and understand plenum cable requirements.
