CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementEasy
A technician is installing a new server in a rack and notices that several unused U-slots have open spaces. To maintain optimal cooling efficiency and prevent hot air from recirculating, what should the technician install in these open spaces?
- ABlanking panels.
- BCable management arms.
- CAdditional exhaust fans.
- DRack shelves for future equipment.
Show answer & explanationAnswer & explanation
Correct answer: A. Blanking panels.
Blanking panels are designed to fill unused rack spaces, preventing hot exhaust air from the rear of the rack from recirculating to the front and mixing with cold intake air, thereby maintaining efficient cooling.
Why the other options are wrong
- B. Cable management arms organize cables but do not block airflow or contribute to cooling efficiency.
- C. Additional exhaust fans might help move air, but without sealing the open spaces, they could draw hot air from the rear into the front, worsening recirculation.
- D. Rack shelves, if left empty, would still allow air to bypass equipment, compromising cooling efficiency.
Blanking Panel
A panel installed in unused rack units (U-slots) within a server rack to prevent hot air from recirculating around active equipment, thereby optimizing airflow and maintaining cooling efficiency.
- Fills empty spaces in server racks.
- Prevents hot/cold air mixing.
- Improves cooling system efficiency.
- Essential for proper data center airflow management.
Memory trick: Blanking Panels Block Bad Airflow.
