The Vertiv Smaract Server 9HE cabinet is a 19-inch floor-standing cabinet with a height of 9 U, designed for use in server and network environments. It features a frame structure with integrated side panels, a lockable front door with perforation, and also a perforated and lockable rear door. The construction made of server steel sheet ensures high stability and mechanical strength. The front and rear doors enable optimal air circulation, which is important for cooling installed devices. The cabinet is painted in RAL7021 Black, integrating it visually into professional IT environments.

Applications
This cabinet is suitable for use in data centers, server rooms, IT infrastructures, and other environments where structured and secure mounting of 19-inch devices is required. The 9 U height provides sufficient space for smaller servers, network switches, routers, or other IT components. The lockable doors increase the security of installed devices against unauthorized access.

Functions and Equipment in Detail
The cabinet is equipped with four 19-inch mounting rails (BL2.5 mm), enabling flexible device mounting. The mounting rails are attached front and rear to vertical profiles, ensuring stable and secure fixation of devices. An earthing set is included in the delivery scope to enable safe electrical earthing of installed components. Additionally, four levelling feet are integrated, allowing for level and stable positioning of the cabinet on various floor surfaces.

Technology Explained Simply
The perforation of the front and rear doors ensures efficient ventilation, supporting the cooling of devices installed in the cabinet. The mounting rails with a spacing of 2.5 mm (BL2.5) comply with the standard for 19-inch mounting and allow the attachment of devices using standard screws. The vertical profiles at front and rear provide a stable mounting base. The earthing set serves for the safe dissipation of electrical voltages and protects against electrostatic discharges. The levelling feet allow height adjustment to compensate for floor unevenness.

Compatibility and Accessories
The cabinet is compatible with accessories from Knürr, including mounting kits for mounting rails (BL2.5 mm, 50- and 100-pack) and L-rails in size T 900/1000 with a length of 711 mm. Additionally, a plinth for cabinet size B600/T900 is available, enabling stable floor fixation. These accessories can be used to expand mounting and fastening options.

Mounting and Installation
Mounting is performed via the pre-defined mounting rails and vertical profiles. The levelling feet are already installed and can be adjusted according to floor conditions. Earthing is carried out using the earthing set included in the delivery scope. The lockable doors are equipped with integrated locking mechanisms ensuring secure closure. Installation requires no additional tools other than standard screwdrivers or screwdrivers for mounting devices.

Advantages in Operation
The cabinet provides a stable and secure mounting environment for IT devices. The integrated earthing and levelling feet ensure safe and level positioning. The perforation of the doors supports cooling, increasing the operational reliability of the devices. The lockable doors protect against unauthorized access. Compatibility with standardized accessories facilitates adaptation to individual requirements.
