A technician working in the datacenter has finished racking a new 4U server into a new rack. Which of the following should the technician do to allow for hot/cold aisle containment?

Implementing hot/cold aisle containment is essential for efficient cooling and airflow management in a datacenter. The correct answer involves installing blanking panels in the rack. This practice helps to prevent hot air recirculation by blocking the gaps in the rack where there are no equipment installed. By doing this, the panels direct the cool air from the cold aisle to flow through the front of the servers and prevents it from mixing with the hot air exhausting from the back of the servers in the hot aisle.

The design aims to keep cold air on one side (the cold aisle) and hot air on the other (the hot aisle), promoting better cooling efficiency and temperature management within the server environment. Therefore, using blanking panels effectively maintains the integrity of this system and ensures optimal cooling performance.
