Chatsworth 39861-721 Double Perforated Metal Rear Door
Overview
The Chatsworth 39861-721 is a double perforated metal rear door designed to provide enhanced ventilation and rear access for ZetaFrame cabinets. This door is crucial for thermal management in dense IT deployments, allowing for improved airflow to dissipate heat generated by rack-mounted equipment. Its perforated design ensures that air can pass through freely, preventing overheating and maintaining optimal operating temperatures for sensitive electronics.
Compatibility
This rear door is specifically engineered for use with Chatsworth ZetaFrame cabinets measuring 52U in height and 27.6 inches in width. It is not compatible with other cabinet series or different dimensional configurations. Ensure your existing ZetaFrame cabinet matches these specifications before ordering.
Installation Notes
Installation requires basic hand tools. The door mounts to the rear of the specified ZetaFrame cabinet, utilizing existing mounting points. Ensure the cabinet is stable and properly grounded before beginning installation. The perforated design allows for rear cable management pass-through, facilitating a cleaner and more organized installation.
