Tool-less snap in 1U and 2U blanking panels

The HotLok® blanking panel is a snap-in blanking panel that provides a 99.97+%+ effective seal in IT equipment cabinets. The state-of-the-art technology, designed for both 1U and 2U openings, controls airflow for optimized cooling effectiveness. They can help reduce hotspots and bypass airflow by preventing equipment exhaust air or hot-aisle air from migrating to the conditioned air-intake stream at the front of the cabinet. Filling unused rack spaces helps deliver lower temperature conditioned air to the upper one-third of the cabinet, typically the hottest area and most prone to equipment failure.

HotLok® blanking panels are available with an integrated temperature strip to help you identify hotspots at-a-glance. The cabinet temperatures, accurate to within +/- 1°, are indicated in colored-coded ranges based on ASHRAE recommendations:

Blue: Optimal operating range

Yellow: Acceptable operating range

Red: Outside acceptable operating range
