Power injector for AP1562I

I need to power an AP1562I a little over 50 meters from indoors.  I have read the data sheet and see the listed power options, however there is no indoor injector listed that will provide enough power to keep the AP from going into low power mode.

 

I have seen the AIR-PWRINJ1500-2= that is listed for the AP1570 and AP1530.  Will it work with my 1562I?  The specs are identical to the outdoor injectors listed for the 1562I.

 

If not, are there any higher power (60W) third party injectors that will work?

 

Thanks.

Go HERE and look under Table 6.  Other than INJ6, the two other injector options are the AIR-PWRINJ-60RGD1 and AIR-PWRINJ-60RGD2.

Thanks.  As I said, I already know what the data sheet said.

Before I upgraded to 8.3.133.0 from 8.3.102.0 it was working fine using an AIR-PWRINJ1500-2.

As you can see ... the injector is no longer working with the 1562I>

[*11/15/2017 14:39:47.8148] Radio1 not started, not enough POE power
[*11/15/2017 14:39:47.8597] Radio0 not started, not enough POE power
[*11/15/2017 14:39:47.8772] DOT11_DRV[0]: set_channel Channel set to 6
[*11/15/2017 14:39:48.2840] Radio1 not started, not enough POE power

 

When I have time, I may downgrade just to see as thankfully I haven't deployed this thing yet.

Figured things out...

The 1560 and even the 2800/3800 APs do not communicate properly using the AIR-PWRINJ1500 when requesting power. The injector will only supply 15.4W to these Access Points which is definitely not enough to turn on the radios and the default power allotted to a device if the protocol request is not understood.

 

I placed the 1562I on a Cisco 2960CX for further testing and got 25.5W out of it to run it in 2x2 mode but in terms of getting 32W out of an AIR-PWRINJ1500 to run the AP in 3x3:3 mode ....

 

Sad waste of perfectly good injectors....

Re: Power injector for AP1562I

Funny that ... 

I am able to (and easily) replicate this with a 1562D/1562E powered by a AIR-PWRINJ1500.  The issue is clearly there when the controller is running 8.5.105.0 and 8.3.132.0, however, once I run 8.3.102.0 the APs are at full power.  

This definitely is an issue with a bug in the AP OS and since the 1800/2800/3800 and 1562 all share the same "code" then I would say that this issue is across that range.  

I have a TAC Case for this and will update this thread once the Bug ID is made available.

Yup same here... got a TAC guy verifying everything himself ...just waiting for his response.

Re: Power injector for AP1562I

Can you PM me your TAC Case number so we don't double up on generating a Bug ID?

Re: Power injector for AP1562I

TAC has provided the Bug ID as CSCvg99574.

Anyone who's experiencing this issue, please raise a TAC Case and tell the TAC engineer to "associate" to this Bug ID (rather than creating another duplicate Bug ID).

Has this issue been resolved? I'm not able to get the radios to work with the AIR-PWRINJ1500 :(

PWRINJ1500 & 1562 is NOT supported.

Re: Power injector for AP1562I

What is the technical reason? Seems like this is something done by choice, rather than an actual limitation.

 

If there is a bug open, then there should be a target fix!

Only Cisco internally will know why they won't support this setup.

Look above for a Bug ID.  They've classed the Bug ID as "Terminated".  Contact your SE/AM for more details.

Re: Power injector for AP1562I

So Cisco is not actively looking to provide any indoor POE injector to make this work? Other than reverting to an older version of code? Rather odd, given this unit works perfectly fine with an earlier code.

Re: Power injector for AP1562I

It's the design of the pre-1560//1570//x800 series Access Point power injectors that's the issue plus how the newer APs accept power now.

 

Before = CDP + even more restrictive coding with the PoE injector company they partnered with...

With the x800 series and if I recall right the 1560 series you should be able to use a LLDP styled PoE injector (aka use an IEEE standard PoE injector)...

 

Its been so long but I do recall using a Cisco-Meraki PoE injector on one of those Aironet APs and it actually powered up just fine...
