Equipment layout and clearances
		GO

Purpose

Minimum clearances must be maintained between the cabinets and surrounding building parts/cabinet to accommodate the installation and maintenance of the base station.

Planning guidelines

The following constraints must be considered for cabinet clearances:

In line-ups where battery back-up cabinets may be needed, the footprint location must be ascertained ahead of time because batteries cannot be added easily to side-by-side cabinets when battery back-up cabinets are in the center of a line-up.

The battery cabinet must be installed adjacent to the power cabinet.

Equipment layout with 3GP24i (new site)

The following diagram shows the equipment layout for a typical new indoor Macrocell site.

Notes:

The cabinets may be placed with zero clearance to the rear wall.

The cabinets may be placed with zero clearance to the side wall, however some clearance is recommended.

Minimum space between the EZBFi frame and the adjacent cabinet or frame is 57 mm (2.24 in.) (if the edge of the template is cut at the dotted line).
