April 22 is Earth Day, our mother planet. Have you ever wondered whether the place where you work, study or stay has solutions that reduce the consumption of our planet’s resources?

Primus Foundation – non public school – example of Cisco Meraki implementation

We will give an example of the implementation of the solution at our client, which took place in 2016 and has been bringing benefits every day since then. Who? All of us and that’s beautiful.

1. About the Primus Foundation:

The school was established on the initiative of a group of enthusiasts – parents who decided to create a school for their children that they dreamed of when they were children. In 1992, their dreams came true! The school exists to this day, enjoying high prestige among Warsaw schools – not only private ones.

The Primus Foundation has been educating Warsaw children and youth for over 30 years.They base their activities on three pillars: high quality of learning, subjectivity of students and sports.With the help of professional staff, it puts great emphasis on the effects of teaching, which can be seen every year in the results of its students in subject olympiads and final exams. Thanks to small classes, they maintain the family character of the school and approach each person individually. They do not use bells, and during breaks they encourage them to use the ubiquitous sofas and chess sets. The physical aspect is equally important for the school – thanks to a full-size hall, outdoor sports fields and an outdoor gym, they have a wide range of opportunities to organize PE classes. Those who are more willing can participate in internal and external competitions, and those who are less willing can relax during a walk with poles in the Kabacki forest or do yoga. Importantly, it is not a private school, but nonpublic – which means that the entire profit is invested in the further development of the school. Graduates can easily get into their dream universities both in Poland and abroad.

The Foundation consists of:

2. What did the client contact us about?

The Primus Foundation, which manages a non-public school in Warsaw, has been looking for network solutions on the market for a long time so that build a reliable network infrastructure for more than 650 students and teachers. The school had a need building a WiFi network to which tablets used by students could be connected. The WiFi network needed wireless points connected to switches to operate, and an intelligent firewall was to ensure overall security.

Market analysis:

The Foundation conducted market research and examined various aspects:

  • purchase cost
  • implementation time
  • maintenance cost (the amount of time it takes to manage)
    ease of management (the school has limited resources)
  • reputation as a manufacturer and partner
  • technical support
  • security against unwanted content for students.
  • ease of integration with iPad tablets
  • energy costs and the ability to manage the power supply of connected devices

3. Our proposed solution.

After analyzing many solutions from various manufacturers, tests were carried out and an offer prepared by our engineers based on the system was selected Cisco Meraki.

The project included

  • WiFi network design – with site survey
  • installation of structured cabling for new devices
  • delivery, configuration and training on Cisco Meraki network equipment, including:
    • 37 MR32/MR52 wireless points
    • 2 PoE switches MS220-24P
    • 1 MX100 edge firewall
    • full license for 5 years.

4. The result of our work:

  • we have identified the best places to install wireless points
  • we installed new structured cabling
  • we installed wireless points and firewall switches
  • we have configured the entire network
  • we trained the administrator

5. Customer benefits:

  • quick implementation time
  • simple maintenance and management
  • automatic updates
  • one dashboard to manage the entire system
  • turning off the power on PoE ports
    • Energy saving
    • improved security, no one could connect to the network outside working hours
    • cost reduction
    • reduction of heat and C02 emissions

In 2021, the customer migrated the firewall to a more efficient one, i.e. MX250.

6. Solved problems:

Solved problems in school with Meraki Solutions:

„The problem concerned filtering out pages containing content inappropriate for students – in most cases it was pornography. After consulting with a Cisco representative, we were able to determine that the unfiltered pages were mainly those that did not contain content in the page description in the <description> tag, or the description was about something completely different. Filtering based on analyzing the content of the page also did not work properly, as it turned out that most of the descriptions posted there were text in the form of images. Most of the undesirable sites came from Russia and several Asian countries. As part of the tests, traffic from these countries was blocked. … everything works wonderfully, and we haven’t noticed that the restrictions put in place have affected the school in any way.”

7. Save on Cisco Meraki:

The school uses two Cisco Meraki switches, which provided PoE power for 63 hours a week, and the power was turned off for 105 hours (outside school opening hours). We checked how much energy the school saved for almost 8 years by turning off 33 PoE ports that powered wireless points.


The current topology of the Foundation’s network in elementary school and high school:

PoE port power schedule

  • Monday – Thursday – during working hours, i.e. from 7.30 a.m. to 17.30
  • Friday – during working hours, i.e. from 7.30 a.m. to 11 p.m
  • Saturday – from 7.30 a.m. to 14.00
  • Sunday – PoE power off

Below is a screenshot from the dashboard of how easy it is to set such a schedule. After setting, you can assign it to selected ports, e.g. those that have the appropriate TAG.


Selected ports worked all the time, and the rest were turned off and on at specified times.



Assumption: power on 33 PoE ports on average 63 hours a week.

  • Saving
    • 62.5% on energy (105h out of 168h per week)
    • withinyear amounted to 1,855 kWh
    • withinfive years 9,273 kWh
    • withineight years 14,837 kWh

If the power were also turned off during the holidays, the savings would be greater.

Data and calculations

The dashboard allows you to check your current energy consumption. This makes it easier to calculate actual savings.

As you can see below, the PoE consumption is 183.2W when the devices are running.

After hours of operation, power consumption dropped to 9.6W
