Due to Insuffiecnt inline pwer. Upgrade inline power source or install power injector.

Dear All,

Here is my issue, Firstly, i plugged the AP 2702i to the switch port model 3560G using RG-45 cable. When i logged into the Ap through the Web Browser, i saw this message as mentioned in the subject title.

At the same time, i touched the AP from the back and it is hot.

Secondly, i plugged the Power Adapter into the AP and now it becomes a little hot. is it normal or not?

After that i typed CLI to check the status and below is the output from the AP:

Kindly suggest me what to do? how can i use PoE without the Power Adapter and avoid heat? is there something special i have to do?

Thank you very much for all your good support.

can you post same output from Switch show inline power from Switch.

[Mahmoudhbm]

Dear balaji.bandi,

Thank you very much for your reply as usual.

Here are two outputs as you requested, kindly keep in mind the AP is connected on switch port number gig0/21.

appreciate it.

is the port connected ? 0/21 we do not see any device connected.

Hello,

Yes, it is connected, check below picture.

the 3560g on supports PoE (15W), and I believe the 2702s need PoE+ (30W) to work. so in short, I do not believe that a 2702 will work with a 3560G, you'd need a new switch that supports PoE+.

Hello cmarva,

Thank you very much for your reply.

Make sense, but recently i am using the power adapter, i remember Mr. Jeremy since CCNA R&S days has explained about the inline power and how to configure the port to use it.

The label on the AP port is PoE and NOT PoE+ with respects of what you answered.

Thank you.

the 2700 series works on PoE standaard; y, take a look at the data-sheet

Power draw    ● AP2700: 15W

PoE+ not necessary, but not all features are enabled on standard PoE

802.3at PoE+

●  Enhanced PoE

●  Cisco AP2700 power injectors (AIR-PWRINJ4=)

●  Cisco AP2700 local power supply (AIR-PWR-C= or AIR-PWR-D=)

Note: If 802.3af PoE is the source of power, the access point will dynamically shift from 3x4 to 3x3 and come up under PoE.

when using a power injector you may disable PoE on the interface with command  "power inline never"

the AP will get noticeable warm, but you can still touch it.  

Cisco Aironet 2702i Operating temperature: 32° to 104°F (0° to 40°C

Cisco Aironet 2700e Operating temperature: −4° to 122°F (-20° to 50°C)

the image you showed reads power-OK / full-power , so this does not look like a problem

test again with PoE from the switchport and issue the command on the switch

     show power inline <interface> detail

Hello pieterth,
using the CLI you have mentioned solved my issue. i configured the power inline never on the port where it is directly connected to the switch and i connected the AP directly to the AC Power Adapter.

I kept the AP On from yesterday till now and no heat at all that's why i replied now :)

Once again, Thank you very much for your great efforts.

hi Mahmoud,

good to hear the situation improved.

and thank you for the points

2700/3700 will operate with 15.4w PoE.
When in 15.4w, the three highest MCS rates are disabled.

Hello cmarva,
You are totally correct.
I solved the heat issue by using the command power inline never.

Once again, Thank you for your reply.
