Question

Hello!

I have PoE splitter (802.3 at) which is used to power raspberry Pi. I use TSW 100 to power PoE Splitter. But power is floating, i.e. raspberry Pi is turned on for 5-6 seconds, then it turns off for a second and then turns on again and then turns off...

In documentation it is said that TSW 100 supply 802.3 at. What can be the problem?

The cable and connection are good. Splitter is workable. Splitter works with another PoE Switch DH-PFS4210-8GT-DP (IEEE802.3af/IEEE802.3at/Hi-PoE) stable.

I tested another PoE splitter (802.3 at, 802.3 af) with TSW100. It worked stable.

Thank you!

Hello,

You have mentioned that TSW100 works fine with another PoE splitter. I suspect that there may be an issue with the splitter itself. Could you share any documentation of said splitter (there may be compatibility issues)? Also, can you tell me more about the cable? Please, only use UTP (Unshielded) cable only when connecting non-Active PoE (non 803.3af/at) equipment.

Regards.

Thank you for answer! That splitter is from China so I couldn't get documentation. I tested both splitters with several PoE switches, also checked PoE wires for switches. 

I came to the conclusion that the problem is in PoE types.

TSW100 is Type B and The splitter which have problems supports only Type A. Another splitter supports both Types so it worked with TSW100. Other swithes supports Type A or both Types, so The splitter worked with them.

Thank you
