PoE Passthrough Switch, 1 PoE in 4 PoE Out Extender, IEEE802.3af/at/bt PoE Powered 90W, 100Mbps Ethernet, Din Rail & Wall Mount Plug and Play

Updating my review to 5 stars based on the seller reaching out and replacing the faulty one even though they didn't have too. Excellent support.Original review below:Failed after a few weeks of use, couldn't find a way to contact the manufacturer for a replacement.

Worked out of the box no issue It was great

Does provide PoE power to downstream devices but blocks Ethernet data. None of my downstream devices were able obtain DHCP leases much less send any other data.** Update **I tracked the issue to a wiring fault. Now it works!

This review is for the 5-port 1000Mb/s (aka, gigabit) version of the switch.The device works as advertised. No down time and no data errors during one month of continuous use with a total load ranging from ~12W to ~35W. (that's about as long as I've had it in use). Using a POE switch as an auto-negotiate PSE (power source), this switch ends up being sensed and treated as an IEEE Class 4 PD (all 4 pairs are in-use for power).It operates fine when passing power at the top of of that range I mentioned (~35W, or 680mA at 53V specifically) for dozens of hours at a time, all while mounted in a passive ventilation enclosure.Recommended.

Now I don't have to step over ethernet cables laid on the floor of my RV... now I run an PoE ethernet cable under the belly of my rv to feed this little PoE passthrough Switch with ethernet connections at other end of my RV. Perfect!

It worked for about a minute, then went completely dead, not passing PoE or ethernet. Tried switch On and Off, no effect. Sending it back.

Now if it had another 10 ports for the same price, what a win :)

This 4-port PoE extender is a welcome addition to the growing zoo of PoE extender modules available on Amazon, many of which add only a single additional PoE port, i.e. 1 PoE in and 2 out. This one, with four PoE output ports, isn't really much larger than those oft-seen 1->2 extenders, and you get three more ports. Provided that you supply it from a PoE source with sufficient power, you can drive up to 60W from Port 1, and the other three up to any combo not exceeding 30W total. Pretty reasonable, considering that many common PoE devices (e.g. security cams) draw only 10-15W.I piggybacked this on top of an existing 4-output port PoE switch in my wiring closet (just contact-cemented it right on top of the metal-case switch) giving me now 7 PoE appearances, in place of the original four, and in a nice compact profile. See photo.Operationally, no issues, works fine. Tested the VLAN mode, operates as expected, providing tag-based isolation between the PoE output ports (i.e. the output ports can exchange data only with the uplink port, but not to each other.)I did notice an oddity when first installing it, but was unable to reproduce it for this review, so take this with a grain of salt: It did seem to be finicky about the order in which ports were plugged in: When the output ports were already plugged into their respective power-consuming devices, and I followed that by plugging the input port into the PoE power source, the devices did not always power up. But when I did it in the reverse order (plug in the uplink port first to its PoE source and then plug the devices in one at a time) the devices came up ok. Possibly a surge exceedance issue in the first case, I don't know, just guessing. But as I said, I couldn't reproduce this behavior when I tried again just now before writing the review. Just something to be aware of.Since it works fine and had no (reproducible) issues, five stars.
