Question 10.
ITCertKeys has a 10-year-old computer room with a 30 cm raised-floor plenum.
They have just completed a change out of some IT equipment and also re-cabled much of the equipment with Cat5E and fiber. They are now having cooling problems in a few areas of the room.
What are two likely cause?
A. The new IT equipment draws air bottom to top, creating heat plumes around the racks
B. When the new cabling was added, the old cable was not pulled from the raised-floor plenum,
creating air dams.
C. Some of the new IT equipment is more dense and is generating more heat than the previous
equipment at that location.
D. The new fiber cable emits more heat than the previous copper network cabling, which causes
an increase in the temperature of the air leaving the perforated tiles.
Answer: B, C
