Temperatura i vlažnost vazduha u data centru
Moraju zadovoljiti kriterijume definisane od proizvođača same IT opreme (ili od ASHRAE) – na frontu rek kabineta.

Merenje temperature u data centru
Na 5 cm od fronta IT opreme, na 3 tačke po visini reka
Najbolje je ako se vrši konstantni monitoring temperatura
