Side cable entry point for network cabinet

The side cable entry point in a network cabinet allows organized, secure, and flexible routing of cables through side panels using brush panels or pass-through openings.

Overview

Side cable entry points are designed to facilitate efficient cable routing between adjacent cabinets or from external sources into the cabinet without compromising airflow or security. These entry points are typically integrated into side panels or gland plates and can accommodate multiple cable types, including Ethernet, fiber optic, and power cables .

Design Features

• Pass-Through Openings: Side panels often include multiple brush-lined openings, commonly sized around 4”W x 8”H, positioned at both high and low points to maximize flexibility for cable entry and exit .
• Brush Panels: These reduce air leakage, maintaining thermal management within the cabinet while allowing cables to pass through without sharp bends .
• Gland Plates and Cable Entry Modules: Some cabinets use modular gland plates that can be replaced with cable entry plates or grommets. These provide IP protection, secure routing, and support for cable diameters ranging from 8 mm to 36 mm .
• Mounting and Security: Side panels are typically screw-fastened or quick-release, with internal fasteners to prevent tampering. Keyed locks may be included for additional security .

Installation and Routing

• Cables are routed through the side entry points directly onto cable clamp rails or management channels, minimizing bending radii and preventing signal interference .
• Side panels can be used in high-density environments, allowing cables to pass between cabinets without overhead or underfloor routing, which simplifies maintenance and scalability .
• For modular setups, unused openings can be covered with solid steel plates to maintain airflow and security .

Benefits

• Organized Cabling: Reduces clutter and simplifies maintenance.
• Airflow Integrity: Brush panels prevent hot air recirculation and maintain cooling efficiency.
• Scalability: Facilitates expansion of network infrastructure without major reconfiguration.
• Compliance: Supports adherence to standards like ISO/IEC 27001 and DIN EN 50174 for structured cabling . In summary, the side cable entry point is a critical feature for efficient, secure, and scalable cable management in network cabinets, combining brush panels, pass-through openings, and modular gland plates to optimize routing, airflow, and protection.
