The Allnet 48,3 cm ( 19 inch )-enclosure of the SNB series, type ALL-SNB6612BDGrau, is a pre-assembled, freestanding network enclosure with a rack capacity of 12HE. It is manufactured in light grey, similar to RAL7035, and is suitable for use in server rooms, IT infrastructures, or small network centers. The enclosure features a glass front door and a rear door, both with integrated locks, as well as two removable side panels, also with locks, enabling flexible use and maintenance. Dimensions are H656 mm × W600 mm × D610 mm, with a usable depth of 480 mm. The pre-assembled design simplifies installation, while the enclosure is fully disassemblable if adjustment or transport is required.

Applications
This enclosure is designed for use in IT and network environments where secure and structured mounting of 48,3 cm ( 19 inch ) devices is required. It is suitable for housing switches, routers, firewalls, servers, or other network equipment. Integrated cable management and brush strips at the cable entries ensure organized cabling and prevent interference from loose cables. The front patch panel depth of 75 mm provides sufficient space for cable management at the front of the enclosure.

Functions and Features in Detail
The enclosure is equipped with four mounting profiles, two at the front and two at the rear, enabling precise installation of 48,3 cm ( 19 inch ) devices. Rack units are marked on the profiles, facilitating device placement. It includes a mid-shelf (D350/W470/H45 mm) with a usable width of 450 mm, as well as a pair of L-brackets (D350/W40/H40 mm) with the same usable width, to securely fix devices. The cable management plate with cover supports structured cabling. Two fans with thermostats provide automatic cooling when temperature reaches a certain level. Grounding is achieved via an M6 grounding stud, with doors equipped with grounding cables to ensure a safe electrical connection.

Technology Explained Simply
The front and rear 48,3 cm ( 19 inch ) profiles are mounted at a distance of 400 mm, which can be adjusted in 20 mm increments up to 480 mm to support various device configurations. Adjustable feet (height 20–70 mm) allow for level positioning even on uneven floors. Cable entries are equipped with brush strips at the top (front and rear) and bottom (front, center, rear) to ensure secure and dust-free cable routing. The doors are reversible, allowing them to be mounted on the left or right side depending on space requirements. The castor set (2x with brakes, 2x without brakes) is included, facilitating transport and positioning of the enclosure.

Compatibility and Accessories
The enclosure is compatible with accessories from the SNB series, such as a castor set, cable ties in various sizes and shapes, blanking plates (4HE, tool-free snap-in), power strips (e.g., 8x or 9x outlets, CEE7 plug), Keystone module holders for patch panels, cable management plates, circuit breaker strips for DIN-rail devices, and cable ties. These components allow for individual customization of the enclosure to meet specific requirements. Additionally, UPS systems such as models PR1000ERT2UC or PR1500ERT2UC, as well as PDUs (e.g., PDU41005 with 8x IEC-C13), can be integrated into the enclosure.

Assembly and Installation
The enclosure is pre-assembled but fully disassemblable, enabling flexible assembly and transportation. Assembly is done via the designated mounting profiles, with 20 cage nuts and screws included in the delivery. The doors and side panels are equipped with locks, ensuring secure use. Adjustable feet and the castor set facilitate positioning. Cable management is supported by brush strips and the cable management plate, ensuring organized and interference-free cabling.

Operational Advantages
The enclosure offers high flexibility with adjustable profiles, reversible doors, and integrated cooling. The pre-assembled design reduces installation time, while disassemblability simplifies transport and adaptation to different spaces. Integrated grounding and brush strips at cable entries enhance safety and functionality. The combination of a glass front door, rear door, and removable side panels enables optimal ventilation and accessibility for maintenance. Compatibility with a wide range of accessories allows for customized configurations for various application scenarios.
