

Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports more than three DRHs.



The recommended thickness of the wall of a pole is 3.5 mm (0.14 in.) or above.

A single DRH can be installed in either side-mounted or standard mode.Figure 3-7 shows a single DRH installed on a pole.



The recommended clearance ensures normal running and provides an appropriate space for operation and maintenance (OM). If there is sufficient space, leave the recommended clearance after installing the equipment.



The minimum clearance ensures normal running and heat dissipation, but OM activities such as checking indicator status and opening the cabling cavity cannot be properly conducted. If the installation space is restricted, leave the minimum clearance after installing the equipment.

3.5.2 Clearances for Three or More DRHs

This section describes the recommended and minimum clearances for three or more DRHs.



The recommended clearances ensure normal running and provide an appropriate space for operation and maintenance (OM). If there is sufficient space, retain the recommended clearances.



The minimum clearances ensure normal running and heat dissipation but do not allow OM activities such as checking indicator status and opening the cabling cavity. If the installation space is insufficient, retain the minimum clearances after the installation.
