Understanding Power Cycle in Networking: Study Notes for Kerala PSC & SSC Exams

Updated on December 31, 2025

Welcome to the Computer Science and Technology Study Materials section from CoreNetworkZ EdTech Solutions for students preparing for SSC, DSSSB, and Kerala PSC examinations. Today, I will explain the concept of Power cycling.

How does This Study Material help PSC, SSC, and DSSSB Aspirants?

SSC, DSSSB, and Kerala PSC conduct examinations for various IT posts. The concept of a 'Power Cycle' is a fundamental troubleshooting step frequently asked in Computer Assistant, System Analyst, and Scientific Assistant exams.

Kerala PSC Degree Level examinations have a Computer Science section where students can expect questions about Power Cycling.

You can check the Kerala PSC Degree Level Common Prelims Syllabus under the Computer Science section. I recommend you download the syllabus using this official link.

  2. Wait 30 seconds

  3. Reconnect the Power supply

  4. Wait for one minute and ensure the active LED lights on the device are not blinking (Power light, Internet light, etc. ).

  6. Does unplug the power cable of modem/router have the same effect of turning off power?(the power cable still plugged tho)

  7. @Elizabeth,

    Theoretically it has the same effect but in technician's point of view, unplug the power chord is better.
