Cable Extension for SX Enclosure

The APC AR7756 is a 750mm wide overhead cable extension designed for SX enclosures. It integrates a vertical exhaust duct to direct hot air away from equipment. This accessory suits data-centre operators who need structured airflow management above their racks. It ships new in black finish.

Thermals and Airflow

The vertical exhaust duct channels heated air upward, reducing recirculation inside the enclosure. Passive operation means no added fan noise or power draw. The 750mm width matches the enclosure aperture so airflow stays contained. Normal use keeps aisle temperatures lower without active cooling components.

Mounting and Compatibility

The kit includes brackets that bolt to the top of an SX enclosure, aligning the duct with the overhead cable tray. No software or configuration is required. Installers who need a different enclosure width or a horizontal exhaust path cannot use this kit. The 2016 release date confirms mature mechanical design.

Questions about this item

How is the 750 mm wide overhead cable extension mounted to the SX enclosure?

The kit attaches to the top of the SX enclosure using the supplied brackets and fasteners; the step often missed is aligning the duct flanges before tightening so the vertical exhaust path stays straight.

What maintenance will the vertical exhaust duct need over time?

Dust builds up on the inner duct surfaces, so schedule periodic vacuuming or compressed-air cleaning to keep airflow unrestricted.

What limit appears first when the duct runs continuously at full load?

The 750 mm width fixes the maximum cross-sectional airflow, so sustained high-density heat loads will hit that thermal capacity before any mechanical wear occurs.
