6 Rack kit accessories

Dell offers thermal, power, and management rack solutions as well as optional rack accessories
designed for maximum compatibility with a wide array of rack enclosure configurations.

Thermal solutions

In order to help with proper air flow in the rack and improve cooling efficiency, Dell offers optional
rack fan kits and blanking panels.
Blanking panels
Dell offers closeout filler panels in a variety of sizes and materials to fit in the Dell PowerEdge racks.
Closeout filler panels, also called blanking panels, provide a way to fill unused rack space in the front
of a rack, resulting in improved air flow to the installed equipment, and reducing hot air recirculation
to the front of the rack. Using closeout filler panels helps to implement data center best practices,
which lead to a common goal: creating the coldest possible intake temperature with the highest
possible volume of chilled- air delivery and the warmest possible exhaust temperature.
Plastic closeout filler panels are tool- less, and provide easy and quick snap- in installation for square-
hole racks. These are available in 1U and 2U sizes.
Steel closeout filler panels provide support for more types of racks, with tooled installation for
square, round, or threaded holes. Multiple sizes are available for optimizing coverage in 1U, 2U, 3U,
or 6U increments, as listed in Table 5. Hardware with #10- 32 threads is provided to support
installation in threaded hole racks.

Fans
Dell offers three rack fans that can be installed in the top of the 42U and 48U racks to facilitate the
movement of air through the upper canopy. The options are 120V, 208V, and 230V to handle
different voltage requirements. The package includes the rack fan, power cable, grounding cable
and cover.
