CompTIA Server+ (SK0-005)Server Hardware Installation and ManagementMedium

A data center technician is installing a new rack of servers. They notice that some of the existing rack units have empty spaces between equipment, while others have gaps above and below installed servers. To optimize airflow and prevent hot spots, which of the following should the technician install in these empty spaces?

  1. APower strips
  2. BBlanking panels
  3. CCable management arms
  4. DSide panels
Show answer & explanation

Correct answer: B. Blanking panels

Blanking panels are essential for maintaining proper airflow within a server rack by blocking unused spaces, preventing hot air recirculation and ensuring cooling efficiency.

Why the other options are wrong

  • A. Power strips provide power outlets and do not fill empty rack spaces for airflow management.
  • C. Cable management arms organize cables but do not fill empty rack spaces for airflow.
  • D. Side panels enclose the sides of a rack, but not the front/rear empty U-spaces.

Blanking Panel

A modular panel designed to fill unused rack unit (U) spaces in a server rack, critical for optimizing airflow and preventing hot air recirculation.

  • Improves cooling efficiency by directing cold air through equipment.
  • Prevents hot air from bypassing equipment and recirculating.
  • Available in various U sizes (1U, 2U, etc.).

Memory trick: Blanking panels 'blank out' the hot air problem.
