  • 1.  Ex4300-48P POE+ Issues

    Posted 05-08-2023 18:42
    Hello,
     
    I have two EX4300-48P in VC mode. 
     
    I have a problem with the POE - it does not work. I attached one AP, and it worked until I tried to reconnect. I tried to connect additional APs, and different models with no success. 
    Also, I tried to connect one Polycom IP phone - it also does not work. 
     
    Currently, I'm using the last Junos:
    Junos: 21.4R3-S3.4
     
    "show poe controller" returns this:
    Controller  Maximum   Power         Guard    Management   Status        Lldp
    index       power     consumption   band                                Priority
       0        925.00W   0.00W          15W     Class        AT_MODE       Disabled
       1        925.00W   0.00W          15W     Class        AT_MODE       Disabled
     
    I tried to change the management mode from Class to Static, but again without success.
     
     
     "show chassis firmware detail" returns:
    FPC 0
       Boot SYSPLD             10
       PoE firmware            2.6.3.92.1

          loader               FreeBSD/PowerPC U-Boot bootstrap loader 2.4
     
     
    I tried to connect the device direct to the switch with a 2m Cat6 ethernet cable to eliminate the eventual cable problems, and it does not work also. 
     
     
    I tried to upgrade the poe controller firmware, but the command returned: 
    (request system firmware upgrade poe fpc-slot 0)
    "Upgrade is not required."
     
    Both chassis have the same issue.
     
    I rebooted the switch, but again not working.
     
     
    Any idea what can be the problem and the solution?
     
    Best Regards,

    How's your config look?  Here's an example of what we have for one of our VC's in the building.

    set interfaces ae0 unit 0 family ethernet-switching vlan members VoIP_Flr_1
    set switch-options voip interface access-ports vlan VoIP_Flr_1
    set vlans VoIP_Flr_1 vlan-id 31

    hello

    The config of one of the ports that I'm trying is as follows:

     show configuration interfaces ge-0/0/37
    description "WiFi AP";
    native-vlan-id 10;
    speed auto;
    ether-options {
        auto-negotiation;
    }
    unit 0 {
        family ethernet-switching {
            interface-mode trunk;
            vlan {
                members [ 3 10 ];
            }
            storm-control default;
        }
    }


    show poe interface ge-0/0/37
    PoE interface status:
    PoE interface                : ge-0/0/37
    Administrative status        : Enabled
    Operational status           :  OFF
    Power limit on the interface : 15.4W
    Priority                     : Low
    Power consumed               : 0.0W
    Class of power device        : not-applicable
    PoE Mode                     :   802.3at

    To clarify, all the ports (ae, non-ae) are working fine, and I have a problem only with the POE. 

    show virtual-chassis
     
    Virtual Chassis ID: fbb0.46c9.f5d5
    Virtual Chassis Mode: Enabled
                                                    Mstr           Mixed Route Neighbor List
    Member ID  Status   Serial No    Model          prio  Role      Mode  Mode ID  Interface
    0 (FPC 0)  Prsnt    xxxxxxxxx01    ex4300-48p     255   Master*      N  VC   1  vcp-255/1/0
                                                                               1  vcp-255/1/1
    1 (FPC 1)  Prsnt    xxxxxxxxx02    ex4300-48p     128   Backup       N  VC   0  vcp-255/1/0
                                                                               0  vcp-255/1/1




    If you need another part of the configuration please specify wich part :)


    I also tried to flash the poe controller using this command: request system firmware upgrade poe fpc-slot file /usr/libdata/poe_latest.s19

    It seems like this command is reflashing the poe controller. If I understand correctly, the poe controller works fine according to the information that returns, but the device attached to the switch port is not powered.
