AP650(AH)'s 1g or 2.5G Ethernet port

AP650(AH)'s 1g or 2.5G Ethernet port

Hi all,

question about our AP's, especially our AP650(AH)'s.  We have abotu 150 or so of them.

We have HP/Aruba 2920 and 2930F switches with Ethernet ports of 100/1000 and its fiber gbic transceiver port is 1000, so they max out at 1gb ports.

When we did this project, the consultant had us plug our AP's into the 2.5g ports of the AP's and not the 1g port, which in turn plug into our switches 1g ethernet ports.

I dont recall what his reasoning was, but im now curious as to why he would have had us do that.  is there really any difference? does it just step down to match our max port speed of 1gb (1000)?  is there any advantage of using the AP's 2.5g port against our switches 1gb port?

Many thanks,
Jason.

When connected to an 802.3af (15.4W) power source, the AP505i, AP510i/e, AP410i/e, AP610c, AP410c operate in Low Power mode with reduced functionality. For the AP505i, AP510i/e, AP410i/e, AP510C/CX, AP410C to operate in normal mode with full functionality it must be powered from an 802.3at switch port or external power supply.

 

The following tables detail the capabilities of each access point when powered using 802.3af and 802.3at.  **Select the appropriate table based on what is proposed**

Thanks all, for your reply.  I guess because it auto-negotiates down, and the fact that a switch may get replaced with a fasted connection, its best to always go with the 2.5g port on the AP's.  That way you are not on a ladder swapping out the ethernet to the other port on the AP.

 

Thanks again, Jason.

if you only have 1g on the switch it doesnt matter which port you use on the ap but i would put it in the 1gb port of the ap. It should work in both ways

It was the consultant we used for the project that said to put them all in the 2.5g port.  as i just posed below, we will keep them in that port, as im sure we will, at some point, upgrade our switches for faster inter-connects and this way, we wont be up on ladders swapping the ethernet on the AP's ports.  Thanks much, Jason
