## Questions & Answers

**Q: Which side of the PoE injector should this be placed?  On the powered side (between PoE/I and the camera) or between the PoE/I and the router?**
A: Man my bad. I though you were looking to buy Ethernet extenders/surge protectors. Yes I use these and the definitely go inbetween the endpoint and the PoE injector/switch. I place mine close to the camera/access point/weather indicators. Hopefully I can delete all that other stuff out.

**Q: How do you know if it's working properly or not? There are no indicator lights on it. Thanks.**
A: This surge suppressor uses fast gas discharge tubes (GDTs) to suppress high energy transients, typically from lightning, but with very low capacitance so as to not affect high speed data circuits (yes this unit works for GigE). The GDTs will show physical damage after a high energy event that leads to failure. Take a look after any lightning hit or nearby hit to your building. However, a series of smaller events may not lead to visible failure, so the unit should be replaced based on an expected frequency of smaller surge events. Note GDTs require high voltage and induced current to trigger, so a close lightning strike (e.g., your backyard) may be one minor GDT event. Check the unit and replace after ~20 such events. A GDT/MOV tester can be purchased, but they are very $$$$ (continuity test is insufficient, you need a breakdown discharge test).  A multimeter continuity test will show open for a good GDT and a typcially failed GDT (failure closed is possible after a severe event in which case damage is visible)  For a typical GDT datasheet see Littlefuse SL1003A Series GDTs here: http://www.littelfuse.com/~/media/electronics/product_catalogs/littelfuse_gdt_catalog.pdf.pdf

**Q: for poe camera on a tower, how will this be mounted to the tower**
A: You should ground the surge protector to your house's common electric ground so mount it as close to your power meter as possible and connect the ground wire there.

**Q: Are the gas discharge tubes replaceable or must the entire unit be replaced after a strike?  Does Tupavco offer the replacements?**
A: The gas discharge tubes are not replaceable. That said, unless the unit takes a direct hit, there is probably no need to replacement. The telephone companies who used to use these to protect lines would leave them in place for years without them loosing effectiveness.
