TRENDnet 5-Port Industrial Unmanaged Fast Ethernet DIN-Rail Switch, 5 x Fast Ethernet Ports, IP30, Operating Temperature Range of -40° – 75°C (-40° – 167°F), Lifetime Protection, Black, TI-E50

Work in a hot condition 135F work great.

It mounts nicely on a DIN rail but you cant easily access the release spring once it is mounted. This makes it hard to release it from the rail or move it once you have it in place. It is fairly low power and has support for dual power supplies. It doesnt come with its own 12v adapter but if you are running this in a DIN rail built enclosure you probably have a 12v din power supply. If not then you will need to get one.

Din rail mount is solid. Switch performance seems fine. No issues.

Works well

Cheap,best and compact.

Returned. 1Gbps capacity is NOT the 1Gbit/gigabit. Im betting they say this because 5x 100 Mbit, in both directions (from the switchs ports and to the switchs ports) is a total of 1Gbps, but no one else advertises switches this way. Misleading on purpose. Makes a slow switch appear as if its fast, when it absolutely is not.

Fixed my internet problems

Compact, seems rugged. Works so far.

Product worked great for what I needed

I have it installed on a DIN rail in the attic. It hasnt been through the full range of temperatures yet, so well see. Of course, I had to buy and hook up a power supply for it, bur this was not a big deal.
