Hello,

 

I have tried to power an AP over a 6 meter long cable and I cannot power it using TL-SG2210MP ports.

 

I have checked the specifications for POE:

Switch 

• Standard: 802.3at/af compliant

EAP245V3 

• 802.3af/A PoE  

• 48V Passive PoE (+4,5pins; -7,8pins. PoE Adapter Included)

 

Tried with 3 cables, 1) a premade 5m FTP cat5E, 2) a 6m cable made by me using a FTP cat5E (solid copper 300 MHz bandwith, it's basically a cat6) and 3) a 0.5 UTP cat5E patch cord.

- with cables 1) and 2) I cannot power the EAP from the switch, but I can power them using the supplied injector (they pass connection test on all pairs and they are good on network mode and they also pass POE fine with the injector)

- with the 3) - patch cord - I can power the device both from the swithc and from the POE injector.

 

I have connected the switch in standalone mode and made slot 8 from the switch high priority POE and tried to connect the FTP cables to that slot, but still, no resolve. 

 

What gives?

 

I think the injector is using 48V Passive Poe but when I use the switch it is unable to negociate power with the device. what can I do, or what am I doing wrong? I am kind of bummed in spending so much money on the switch without having the posibility to actually use it.

 

LE: got tired and just used the POE injector, but when connecting the data port from the injector to the switch nothing happen and I cannot establish a wired connection with the AP. Tried with both cables, premade and custom, nothing. If I remove the same patch cord from the injector and insert it in an laptop I have a network connection, no problem. the same with the other two cables. 

 

the only way to have a wired connection is with the short patch cable.  this is truly maddening!

 

 

In port 4 I have a gigabit connection with the laptop. The same cable (cable 2 , premade purchased cat5E FTP) cannot give POE to the EAP. in the port 6 I have the UTP path cord with the EAP.  the link is only yellow 100 Mbps.

 

next step I remove the patch cord from port 6 and EAP, insert it in slot 5 and the laptop and the controller shows gigabit connection,

 

Should I be worried? RMA the EAP? First EAP works fine with an injector and a 15m cat 5e FTP T568B terminated cable (300 MHz, solid copper same as the 2) cable used with the second AP and also has gigabit connection.
