FAQ
What is RackWatt?
RackWatt is a fully offline field toolkit designed for data center critical facilities technicians, operations engineers, and commissioning agents. It digitizes the Method of Procedure (MOP) for step-by-step execution, includes a suite of power and cooling calculators, and provides offline troubleshooting guides for equipment.
Does RackWatt require an internet connection?
No, RackWatt is designed to work entirely offline. This is crucial for data center environments which are often radio hostile and access controlled, ensuring full functionality without any connectivity.
How does RackWatt handle procedure execution?
You can build or import a Method of Procedure within RackWatt and execute it step by step. The app automatically timestamps each step, allows for notes, photos, and readings, and concludes with technician, peer reviewer, and manager signatures, exporting a signed PDF record.
What kind of calculators are included in RackWatt?
RackWatt offers a comprehensive suite of power and cooling calculators, including UPS battery runtime, UPS sizing, generator fuel runtime, three-phase power, rack power density, PUE, redundancy modeling (N, N+1, 2N, 2N+1), arc flash awareness, airflow and heat load, delta T targets, and refrigeration calculations. All results show the formula, source, and intermediate steps.
How does RackWatt assist with equipment troubleshooting?
RackWatt provides searchable, offline reference guides for various equipment like UPS, generators, electrical distribution, and cooling systems. Each entry lists warning signs and an ordered list of checks, prioritizing the most likely causes. Guided decision trees help triage issues like utility loss, unit on battery, or cooling failures.
What types of documents can be managed in RackWatt?
RackWatt supports libraries for Standard and Emergency Operating Procedures, commissioning levels, rounds and readings, preventive maintenance, work orders, incident and near miss reports, lockout tagout permits, arc flash assessments, and change/risk records. Documents can be routed to preset recipients, with emails queuing for sending when connectivity returns.
