What is a Wall-Mount Network Cabinet?

A wall-mounted network cabinet is a compact cabinet that mounts on a wall or column. It is primarily used for centralized deployment and management of network equipment (such as switches, routers, and fiber optic patch panels). Its design balances space conservation and equipment protection, making it suitable for small and medium-sized network environments.

1. Features of a Wall-Mounted Network Cabinet
Space Optimization
Typically ranging from 300 to 600 mm in depth and 400 to 1200 mm in height, it is suitable for confined spaces (such as offices, corridors, and low-voltage electrical rooms).
It can be mounted on a wall or on a column, eliminating floor space.

Structural Design
Material: Cold-rolled steel (mainstream) or aluminum alloy, ≥1.2 mm thick, rust-resistant and shock-resistant.
Ventilation and Cooling: Top/bottom openings or fan-equipped (some models support forced ventilation).
Security: Lockable front door (side-opening or front-and-back opening) to prevent dust and foreign matter from entering.

Compatibility
Standard 19-inch rack width (482.6mm), supports U-mount installation (1U = 44.45mm).
Accommodates devices such as switches, routers, PDUs, and fiber optic terminal boxes.
Select models support expansion with accessories such as fixtures, cable management racks, and grounding terminals.

2. Precautions for installing a wall-mounted network cabinet
(1) Preparations before installation
Confirm the wall type and load-bearing capacity
Solid wall (concrete/brick wall): Use M8 or M10 expansion bolts (each bolt has a load-bearing capacity of ≥20kg).
Gypsum board/lightweight partition wall: must be positioned to the internal keel, or a back support frame (such as a steel pipe beam) must be installed.
Steel structure wall: Use self-tapping screws or welded brackets.
Check the integrity of the cabinet accessories
Confirm that the mounting brackets, bolts, keys and other accessories are complete.
Check whether the cabinet dimensions (height × width × depth) are consistent with the plan.
Tool preparation
Electric drill, level, torque wrench, laser rangefinder (ensure alignment).

(2) Installation location selection
Space requirements
Reserve ≥60cm of operating space in front of the cabinet and 30cm of heat dissipation clearance at the top.
Avoid installation near humid, high-temperature (such as next to a heater) or vibration sources (such as an air conditioner outdoor unit). Height planning
The bottom should be ≥30cm from the ground (moisture-proof and kick-proof), and the top should not exceed 2m (easy to maintain).

(3) Installation steps and specifications
Use a level to mark the installation hole position and ensure that the cabinet horizontal deviation is ≤2mm/m.
The drilling diameter is slightly smaller than the expansion bolt (e.g., drilling a Φ10mm hole for an M8 bolt).
Solid wall: All expansion bolts must be tightened, and the exposed thread must be ≤5mm.
Lightweight wall: The bracket must span at least two keels, with ≥4 fixing points on each side.
Mounting the cabinet
Two people work together to lift the cabinet, align it with the bracket slot, and then slowly lower it.
Check that there is no gap between the cabinet and the wall, and that the door opens and closes smoothly.
Use a 6mm² yellow-green two-color wire to connect the cabinet grounding terminal to the building ground grid, with a grounding resistance of ≤4Ω.
