Outdoor PoE switch is too hot
High temperatures may cause the power supply chip in the PoE module to trigger overheat protection, resulting in a direct power supply interruption. When installing PoE switches outside, climate control should always be considered because extreme temperature fluctuations can cause the switch to malfunction. Come-Star's industrial PoE switches can operate at temperatures ranging from -40°C to +75°C and store at temperatures from -40°C to +85°C! They can adapt to various high and low-temperature. But I'm worried about how it will handle hot summer temps (up to ~100 degrees Fahrenheit outside with 100% humidity). However, PoE setups can encounter various issues. Here are some common PoE issues and how to troubleshoot them: 1. The other option would be a standard 5 port switch with 4 PoE injectors, this is not ideal both due to price and I'd imagine this may run into the same.
