Site Prerequisites

This section summarizes power, grounding, environment, and clearance requirements that must be met prior
to installing and operating the ASR 5500. For detailed information, refer to the Technical Specifications

Power and Grounding

Each PFU requires eight power feeds of 80A @ -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. For additional information on power requirements, see the Technical Specifications
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 5500 chassis to assure adequate conductivity.
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.
