Power distribution system

Power distribution systems

Used to ensure consistent and reliable power delivery for networking equipment, infrastructure, and environments

Uninterruptible power supply (UPS)

An electrical apparatus that provides emergency power to a load when the input power source fails

Good for short-duration power outages

Usually installed in server racks

Power distribution unit (PDU)

A specialized device for distributing electric power to various network components and computing equipment

Only designed to provide power protection from surges, spikes, and brownouts

Like a power strip

Generator

Installed outside of a datacenter to provide longer-term power during a power outage in a region

Can be powered by diesel, gasoline, or propane

Managing power loads

Critical in preventing circuit overloads and ensuring efficient power usage inside datacenters

Usually done by someone calculating and monitoring the power loads on each circuit

Voltage considerations

Always check the voltage on the device you are installing

Most equipment are considered dual-voltage and can be configured to operate at either 120 volts or 230 volts

Voltage

Electric potential difference and is a key factor in power distribution systems
