What role does a UPS play in a network setup?

A UPS, or Uninterruptible Power Supply, is an essential component in a network setup primarily because it provides backup power in the event of an electrical failure. This ensures that devices connected to the UPS—such as servers, routers, and switches—can continue to operate without interruption during power outages. This capability is crucial for maintaining network availability and can protect data by allowing for safe shutdowns of equipment, thereby preventing data loss or corruption.

In addition to backup power, a UPS often includes surge protection features, which safeguard equipment from voltage spikes, contributing to the longevity and reliability of network devices. This aspect is especially important in environments that demand high availability, such as data centers or enterprise networks.
