Power Supply System
If you use a DC cabinet, ensure that the outputs of the DC power distribution box fall within the range of –72 V DC to –38 V
DC. Two different power sources are required for redundancy.
If you use an AC cabinet, ensure that the outputs of the AC power distribution box fall within the range of 90 V AC to 264 V AC.
Two different power sources are required for redundancy.
Clearance Requirements
Airflow clearance: The spacing between the air intake of the cabinet and neighboring objects must exceed 75 mm. If the air
intake of the cabinet is next to another communication device, the spacing must exceed 150 mm.
Maintenance clearance: The spacing between the rear of the cabinet and neighboring objects must exceed 350 mm for
maintenance.
Cabinet Clearance Requirements (Using N68E-22 As an Example)
Aisles in the equipment room ≥ 1000 mm; aisles between cabinet rows ≥1000 mm
