Figure 9. Unorganized cables (left) and organized cables (right) beneath a raised floor.
Electrical and network cables from devices in the racks pass through cutouts in the tile floor to
wireways and cable trays beneath the floor. Oversized or unsealed cable cutouts allow supply air to
escape from the plenum, thereby reducing the static pressure. Self-sealing cable cutouts are required
to maintain the static pressure in the plenum (Figure 10). Cable management in high-density sever
environments can significantly affect cooling issues.
