0 items reviewed

Utility feeds and their upstream common points are understood.UPS capacity, battery condition and maintenance bypass arrangements are documented.Generators are tested under load and have realistic fuel and refuelling plans.Power distribution remains within capacity when one path is unavailable.Rack equipment uses separate power paths where required.Cooling capacity, airflow and localized temperature monitoring are adequate.Carrier entries and internal fibre routes are documented.Critical network and facility alarms reach named responders.Authorized personnel can access the site during an emergency.Extended-outage suppliers, contacts and escalation paths are current.Maintenance states that reduce redundancy are formally controlled.Recovery and shutdown priorities are documented for prolonged events.

Facility scope

A facility review should cover the chain from utility and carrier infrastructure to the rack. A redundant device is not protected if the shared room, distribution panel or cooling system fails.
