▀ Site Prerequisites

Site Prerequisites
This section summarizes power, grounding, environment, and clearance requirements that must be met prior to
installing and operating the ASR 5000. For detailed information, refer to the Technical Specifications chapter.

Power and Grounding

Each PFU requires a power feed of 160A @ -48VDC (nominal). The feeds should be routed to the installation rack from
the site power supply using adequately sized conductors and circuit breakers in accordance with local electrical codes.
The chassis must be grounded to a site ground point using the recommended conductors and lugs. The ground point
should be in close proximity to the ASR 5000 chassis to assure adequate conductivity.

Environment

The site's heating ventilation and air conditioning (HVAC) systems must be sized to maintain the operating
temperatures and relative humidity specified in the Technical Specifications chapter. HVAC capacity requirements will
vary based on the system configuration and associated power draw, as well as the operational characteristics of other
equipment installed at the site.

Clearance

Adequate clearance must be maintained at the front and rear of the ASR 5000 chassis to assure proper air flow and
allow maintenance access for the installation, removal and replacement of components. The recommended clearance is
30 to 36 inches (76 to 92 centimeters) at the front and rear of the chassis.
