The flexibility of mounting, airflow, and cable management options make the 5G cabinet suitable for a multitude of
industrial, telecom, and broadband applications.

The NEMA Type 3 cabinet originated as a micro data center that facilitates a nationwide roll-out of 5G wireless network coverage. Great Lakes manages an intensive inventory program to ensure each cabinet is configured with cable management, power, and grounding equipment and accessories. All customer-specified components are installed, wired, and tested at Great Lakes so that a configured cabinet arrives at the service provider’s warehouse and is ready for specialized rack-mount equipment.

Each GLBX04-5G cabinet includes listed components and accessories, as well as an airflow unit. The selected part number dictates if an AC Unit or Heat Exchanger is included with the cabinet; note that the AC or Heat Exchanger cannot be swapped in the field as the cabinet door is specific to the airflow unit.
