Power Injector Issues

[shreemahida]

Hello,

The power injector I am currently using (Model: DPSN-35FB A) has a blinking green LED for AP Power and a solid green LED for AC Power. I'm not sure if this is supposed to happen or if there is something wrong with the power injector. 

Appreciate the help

i found on some power injectors that pins that send power they change.

throw i not shure but i removed wires from pins 5,6,7,8 and unit powers up

this sujest that power is sent on pins one throw 4

i have confirm that two of wires are carrying voltage

so how cable is wired is most imported

u can not use cross over cable between the injector or ap

i can not confim this is case for all units,

only ones i have. but would make sence that cisco would do everything the same

now i not sure if power sent on all 4 wires or just two , i not gone so far,

i shut down the swich as got to cold to work on

but something to consider

[jamesbos96602]

i confirm that cisco uses pins 1-2 -3 -4 for power  u can not use a cross over cable,  5-6 7-8 is use for data ,

no other company dose this that meens  must be cisco device unless u change the cable

now it might need cross over cable from swich to poe  i seen this as well

but from poe to ap wires  must be stait throw

Does the power injector work?

[jamesbos96602]

if he has lights it working quistion becomes if he has right cables for it , some times a crossover cable needed befor the injector some do not requre this but u never use cross over cable after the injector u burn something out

[Scott Fella]

I never seen a power injector that uses a crossover cable.  How I understood the question is if the blinking lights were okay, so yes, the power supply has power to it, I want to know if the ap powers up or not.

[jamesbos96602]

i have had units requred cross over cable  but u got flashing green light it not the injector, it in the cables or there is reason why

the data is not going to device,  wifi up . dose this wifi use a controler to run it , or is it stand alone 

probem is it not linking or getting dhcp , where i start is reset the wifi, if that fails replace bouth cables,. if  that fails then replace injector , if it like to a controler probem is in controler and i run debug commands see if anything pops up

some wifi requres a encripted channel as u not stated how this wifi is set up or show logs of wifi best we do is guss

@shreemahida does your ap power up?

[jamesbos96602]

Ap powers or light not be green sound like not getting data or encryption not same 

willing bet it working on dhcp 

and not getting dhcp addresses 

but without debug logs every thing said Gus’s work 

sold green light when unit a) has static ip and can access the gateway or b) until on dhcp

wich until waiting for dhcp ip assignment 

c) one or both cables has problems of some kind 

d) encryption dose not match the dhcp server and or gateway
