AP-205H Ethernet ports function

Hi community,


What is the function or role of the different Ethernet ports in AP-205H? I am clear that E1-E3 ports are the downlinks, and E0 is the uplink, but which E0 specifically? There is a E0 at the back, a E0/PT at the bottom and a PT port at the back. What is the relation between all of them? The AP-205H Installation Guide says:


Additionally, the IAP-205H access point has a Pass-Through (PT) port at the back (Figure 2) and an E0/PT port at the bottom (Figure 3). The E0/PT port acts primarily as a Pass-Through (PT) port. Alternatively, the E0/PT port can serve as an E0 uplink port and accepts 802.3af/802.3at PoE power when the E0 and PT ports at the back of the AP are physically bridged by an Ethernet cable.


PT is a Pass-Through port, but E0/PT is also a Pass-Through port. But what does exactly mean a Pass-Through port? I don't understand that explanation. Can you put an example? I am powering my AP-205H with a DC power source (no PoE), what port do I have to use for the uplink? E0 at the back? Or E0/PT at the bottom? Or either?


Many thanks in advance.

Answered here. PT on the back is with just wires connected to the E0/PT on the bottom of the AP and allows you to connect the uplink on either the back or the bottom. When mounted to the wall, you could even use the Pass-through to patch another UTP or even analog phone cable from the wall to the bottom of the AP.

If you have urgent issues, please contact your Aruba partner or Aruba TAC (click for contact details).
