Power Distribution Systems (obj 2.4) Flashcards
(13 cards)
What is the purpose of Power Distribution Systems?
Crucial for consistent and reliable power delivery
Power Distribution Systems ensure that electricity is efficiently and reliably delivered to various components within a facility.
What does an Uninterruptible Power Supply (UPS) provide?
Emergency power during main power failures, surge protection, and line conditioning
A UPS typically lasts between 15 to 30 minutes and is essential for maintaining operations during power outages.
Where is a UPS typically installed in data centers?
At the bottom of each rack
Some data centers may use larger UPS systems to support multiple racks or the entire facility.
What is a Power Distribution Unit (PDU)?
A specialized device that distributes electric power to network components and computing equipment
PDUs are advanced power strips that may include power monitoring and control features.
What are the characteristics of a PDU?
May be rack-mounted or in large cabinets, provides surge protection but not full protection against complete power loss
PDUs are crucial for managing power supply in environments with multiple servers.
What is the function of generators in data centers?
Provide longer-term power during outages
Generators are typically powered by diesel, gasoline, or propane and are paired with UPS for seamless power transition.
What is the role of an automatic transfer switch?
Shifts power between UPS and generator
This ensures that power supply is maintained without interruption during an outage.
Why is Power Load Management critical?
Prevents circuit overloads and ensures efficient power usage
It requires careful calculation and monitoring of power loads on circuits.
What must be considered when installing new equipment in a data center?
Assessing power impact and balancing loads across the data center
This ensures that existing circuits are not overloaded and that power distribution remains efficient.
What is the US standard voltage for power distribution?
120 volts
This standard voltage is crucial for ensuring that equipment operates properly.
What is the European standard voltage for power distribution?
230 volts
Equipment must match these voltage standards to avoid damage or operational issues.
What can dual voltage equipment do?
Operate on both US and European voltage standards
This flexibility is beneficial for equipment used in international settings.
What are some key considerations for data center power management?
Install UPS, PDU, and backup generator, ensure seamless power transition, consider power loads and voltage requirements
These considerations help maintain reliability and efficiency in data center operations.
