    Wink PoE Problems

    I have a Cisco WS-C3560-8PC in our maintenance dept that shows the following when I run a show power inline.

    Interface Consumption Admin
    Configured Consumption (Watts)
    ---------- ----------- -------------------

    Fa0/1 NO 0.0
    Fa0/2 NO 0.0
    Fa0/3 NO 0.0
    Fa0/4 NO 0.0
    Fa0/5 NO 0.0
    Fa0/6 NO 0.0
    Fa0/7 NO 0.0
    Fa0/8 NO 0.0

    I have two Cisco PoE phones hooked up to this switch that are on and I can see when I run show CDP Neighbor any ideas. I have reset the switch physically. I'm guessing this thing is fried I just wanted a second opinion.

    Thanks!!

    Unusuaul..

    try a
    power inline never
    then
    power inline auto

    Also
    sh interface capabilities
    see if it mentions POE.


    If you bought it new just get the supplier to raise a TAC with Cisco, if they can't advise of a fix then they will replace it.

    No luck with the first commands. This switch is out of warranty so I think it's time to get a new one. We are going to have our electrician look at the power in this building before replacing the switch.

    FastEthernet0/1
    Model: WS-C3560-8PC
    Type: 10/100BaseTX
    Speed: 10,100,auto
    Duplex: half,full,auto
    Trunk encap. type: 802.1Q,ISL
    Trunk mode: on,off,desirable,nonegotiate
    Channel: yes
    Broadcast suppression: percentage(0-100)
    Flowcontrol: rx-(off,on,desired),tx-(none)
    Fast Start: yes
    QoS scheduling: rx-(not configurable on per port basis),tx-(4q2t)
    CoS rewrite: yes
    ToS rewrite: yes
    UDLD: yes
    Inline power: yes
    SPAN: source/destination
    PortSecure: yes
    Dot1x: yes

    Thanks for all your help with this issue!

    It's under cisco lifetime waranty, so long as you know who you got it from.


    I would download and install the latest IOS from cisco for the model as it may be a IOS glitch.
