48 Port Full PoE vs 48 Port PoE

Guys I am trying to determine what the difference between "full poe" and "poe"

I am replacing a few WS-C3560G-48PS-S switches at my clients and need to make sure I am providing them with the same PoE functionality that they currently have with the WS-C3560G-48PS-S.  I am trying to decide from the sku's below.  I also would like to use stackpower.  Any help would be great!!

WS-C3750X-48P-S    
WS-C3750X-48PF-S


WS-C3750X-48P-L    
WS-C3750X-48PF-L

Re: 48 Port Full PoE vs 48 Port PoE

2960S/X/XR, 3560X/C/CX, 3750X, 3560 & 3850 support PoE+ (up to 30.0w per port).  Some 3850 support uPoE.

Like any Cisco Catalyst 48-port standard PoE switch, it will only support up to 24 ports at 15.4w (on a first-come-first-serve-until-full) but can support 48-ports at 7.7w (some can).

A "full" 48-port PoE means that the switch can support 15.4w to all 48 ports.

Does this help?  Please don't forget to rate useful posts.  Thanks.

Re: 48 Port Full PoE vs 48 Port PoE


As per datasheet in 3850 switch, WS-3850-48P should be able to support PoE+ -- up to 30W.

However, in the cisco power calculator http://cpc.cloudapps.cisco.com/cpc/FXS.cpc  why I couldn't chose any item with 30W?

can anybody tell me is 3850-48P could support 30W PoE?

 

many thanks~

3850-48P can support 30w. 

The question you need to ask:  How many ports can the switch support 15.4w or 30.0w?

Re: 48 Port Full PoE vs 48 Port PoE

how many port support can actually be count using the power calculator. however,

Cisco Power calculator do not have option for 30W equipment for 3850.

 

In cisco Power calculator for 2960X, there is option for 30W equipment.
