Buyer Beware – Caveat Emptor.
A few solid tips to understand and keep in mind when thinking about buying a PoE (Power over Ethernet) Injector or Midspan.
First tip: Not all are created alike or are reliable.
A PoE Injector or PoE Midspan converts AC Voltage (dirty power) into a DC Voltage (clean power) signal and outputs this onto a IEEE Ethernet 802.3 standard RJ-45 female jack with a Ethernet LAN switch inside. Typically 120V AC – 260V AC input converted into a 12V DC – 90V DC output. The LAN switch can be 10Mb, 100Mb or Gigabit.
Your business deserves a solid made, reliable PoE Injector or PoE Midspan that has at least a 4 year warranty. Any downtime costs your business money. Beware of cheap Chinese LAN products as the product quality and your LAN security are often compromised.
A good PoE (Power over Ethernet) Injector or PoE Midspan is not just responsible for providing power to your PoE devices, but it also plays a very important role in the secure transfer of your data. You don’t want to worry about a simple looking PoE Injector leaking your business secrets to Chinese competitors or work at your office experiencing any technical interruptions then you should ensure that every piece of equipment is of the highest quality that you can trust.
Second tip: PoE Injectors or PoE Midspans are designed with false distance limits.
Manufactures typically follow the IEEE 802.3 Data Standards that have a distance limit is only 328 feet or 100 meters. To overcome this false distance barrier the use of PoE Extenders can drive both Ethernet and PoE up to 3,500 feet or 1,067 meters – That is over half a mile!
Third tip: Avoid PoE Injectors or PoE Midspans that use Power Detection (PD).
Part of the IEEE 802.3af and at standard for PoE allows for a Power detection (PD) protocol that will stop and shut off your power completely if a PoE device is beyond 328 feet or 100 meters because of a timing mechanism in the PD protocol.
This unfortunately is a LAN engineer design flaw as any electrician can tell you power will run over wiring a hell of a lot further than 328 feet. You don’t have to be crippled by this oversight. To overcome this issue you have two choices. 1) Get an Injector that has PD disabled or 2) Use PoE Extenders that can drive both Ethernet and PoE.
Overall: Don’t let a PoE (Power over Ethernet) Injector or PoE Midspan be the weakest link in your network. Don’t let price fool you as you get what you pay for. Look for real value in the solution you implement for the long term. Time is money and making a selection on quality, security and features needs to serve your business the way that you deserve.
The best way to ensure profitability is to invest in technology that you can trust. If the product quality is sub-par you can be sure that you will lose crucial data and productivity will ultimately head in the wrong direction.
