  • Removing the fan from a PoE switch

    Removing the fan from a PoE switch

    Remove the 4 screws on the back of the switch and carefully lift off the top cover. Install the Noctua fan in the same orientation. Have you ever removed fans from a switch? I just got a Cisco SF300-24PP and I expected the fan noise but not as much as it is So I'm thinking of removing the fans on it. Even under. Hopefully this guide helps any other brave souls looking to quiet down their UniFi gear. Not ideal to use this. Replacing the factory fans could be an option but for two issues; first the warranty, second finding a suitable replacement is difficult due to the signalling pin / speed pin which when wrong results in the fan light illuminating or the new fans not spinning at all. However, it doesn't show you how to replace the fans for the power supply, largely because the power supply on non-PoE EX2200s doesn't have fans (see YouTube preview above).

  • PoE Switch Calculation Method

    PoE Switch Calculation Method

    The calculation is simple: list every PoE device, note its peak power usage, sum those values, and add a safety margin. If the result is, for example, 150W, you need a switch with at least 150W total PoE power. Factoring in future expansion is also wise. This tool checks if your PoE switch can power a given number of devices (e. To do that, you have to consider the device as a whole, the ports available, and the devices that you want powered when they connect to your power sourcing equipment. Accurate PoE planning requires: Ignoring physical-layer electrical losses can result in: PoE budgeting is electrical engineering - not guesswork. Longer runs increase resistance, which raises loss between the power source. To calculate your PoE power budget, add up every device's maximum power requirement, then pick a PoE switch that can supply enough wattage for all of them at once.
