M4300-96X Max POE 15W ports

I have just seen this small snippet in the spec sheet for the M4300-96X switch.

    *Only first 6 slots are delivering PoE power to APM408P cards for 48 PoE+ ports per switch.

 

Since POE is a copper Base-T thing, It looks like its only the APM408P which does POE on this type of switch.

So even with a 1200W PSU, only 48 ports can do POE.... is that right ?

  • Yes, this is related to the power lane availability to the first six slots, and also mentioned on the module specs:

    - Port card with 8-port 100M/1G/2.5G/5G/10GBASE-T PoE+
    - Fits into one front slot of M4300-96X Modular Managed Switch
    - M4300-96X offer 12 slots in 2RU for 8x10G or 2x40G port cards
    - PoE is supported up to 48 x 10G PoE+ 30W per system (first 6 slots)
    - 1440 W PoE Budget with 2 x APS1200W shared PSUs

      Thanks for the confirmation.

      So I have 5 floors with need for 80ports of POE+ 1Gbps per floor.

      Looks like I am going to have to have 2 stacks to achieve this....

      Cant see another way given the 8 devices limit in a stack.

      Apart from the additional overhead of management of 2 stacks, thereis not

      neccessarily a big downside to this I guess, so long as transit is fat enough... 4* 10G etc...

        Sigh, yes, two M4300-96X enclosures, but both can be configured into a single stack of course. LaurentMa can you confirm this svp.?
