Power Injector & WISM

I am trying to connect a Aironet 1242 LWAPP AP to a Cisco 3524 non POE switch.For some reason I cannot access the power settings for the APs.What I do is ,got toConfigure ->Access points and slect the AP.My gut feeling is that I should modify the poer settings inorder to connect a power injector.I get a consistant amber light on the status LED and I feel its not normal...

When an LWAPP-enabled access point (such as an AP1131 or AP1242) is powered by a power injector that is connected to a Cisco pre-Intelligent Power Management (pre-IPM) switch, you need to configure power over Ethernet (PoE), also known as inline power. You can configure PoE through either the GUI or the CLI.

Report for Power Injector State

I need a report for all Power Inyector installed with a AP, how i have this information in a report?
please i need help

The is no way to detect if your using a power injector or not. There are commands to enable if your using a power injector, but that doesn't mean its not connected to a PoE switch.
That would be a manual process of going to each ap and looking.

Power Consumption of Power Injector

Hi,
Hope you can assist me. My customer requested me to calculate the power consumption required for the installation of one unit of AP 1510 using the following power injector, part no: Power Injector (AIR-PWRINJ1500). He would like to know the cost required so that the building management can include the necessary cost of the implementation of the device.
From my initial research, I notice the following input power requirement
Power Injector
Input: 100-240V ~ 1.5A (300Watt)
Output: 48V ~ 1.2A (58Watt)
Power consumption: 240*1.5 = 360 W = 0.36KW
Assuming cost per unit is 0.39 cent
Amount required per hour = 0.36*0.39 = 0.14 cent
Amount required per day = 0.14*24 = 3.36 dollar
Is my calculation correct?
Thanks.

LWAP PoE settings when using power injector

We have 3500 series access points connected to a 5508 WLC. What power over ethernet option should I select for an AP thats using a power injector? Prestandard State or Power Injector State?

Just leave it alone. This setting is for old APs like the 1130 and 1240 and older.

Incorrect power injector

I have purchased several AIR-LAP1242AG-E-K9 but had no POE switches so I needed power injectors; we ended up purchasing AIR-PWRINJ-FIB without noticing that they were also media converters.
Is there any converter I can use to convert back to copper? I wanted to confirm this before getting to the inevitable conclusion that we need to exchange them for the AIR-PWRINJ3

Hi Javier,
You may want to take a look at the following media converter:

Aironet 1310, power injector and poe cable

Hello,
Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
Thanks in advance,
lachapelle

Hi lachapelle,
Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
Dual coaxial cable to run from the power injector to the 1300. See attached notes:
Cisco Aironet 1300 Series
Cisco Aironet 1300 Series Access Point/Bridge Power Injector
The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters.

Sorry, but Power over Ethernet is not supported on the AirPort Extreme.

Power Injector for 1310 wireless bridge

Hello,
We have a failed power injector on a 1310 series bridge. Will the "Power Injector LR" from a 1410 series bridge work on the 1310?
Thank you,
Matt

No... both have a different output and should not be used interchangeably.

Can not find Power Injector for wap2000.

Hello everybody.
Not long ago i was bought Cisco wap2000 access point for small business, and now the problem is to find power injector for this device.
I am already tried to use AIR-PWRINJ3, but access point did't turn on.
Why?
Which power injector should i use with this device?
Thanks.
PS.
Please, don't judge me, for my bad english. =)

I would think that:

should work, Cisco should be able to confirm . . .
If not then I would try:

I know your original post was in January and you may have created that 100m power cord but I hope this helps others.

WAP4410N - Will the PWRINJ4 power injector be compatible

Good day,
We have purchased a few WAP4410N access points at some of our small remote offices. The switches in the offices is not PoE capable, therefore we require power injectors. I have a PWRINJ3 injector in my posession, so have tested it with the AP's, but it does not seem to be compatible.
Before I purchase power injectors, I would like to know whether the PWRINJ4 will be compatible, if not, which power injector does Cisco recommend for the WAP4410N.
Kind Regards
Adrian

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.
We get this question a lot with our wireless AP's. Currently there is not an Injector that we recommend with our wireless AP's. Your best bet is to purchase a small unmanaged PoE switch for all of your AP's. I would suggest something like a SG-200-08P.
http://www.cisco.com/en/US/products/ps11229/prod_models_comparison.html
Cisco currently has an injector in works for our small business devices, but the timeframe for availability is unknown at this time.
There are some 3rd party infectoers on the market(including Cisco Enterprise injectors that could possibly work, however since we do not support them and they have not been certified for use with our small business devices we can not recommend or support them. (even though some customers have been lucky enough to get them to work)
Hope this helps, please let me know if I can answer any other questions.
Thanks

Cisco Power Injector - AIR-PWRINJ4

                   Hi there, I have a quick question about Cisco Power Injector.
                    we bought a number of Air-PWRINJ4 year ago, mainly for extending the power via Cat5 ethernet cable to AP 1225 in warehouse. the output is 56V 0.55A.
                    Now I have a couple of spare left, my quesiton is if it is OK to directly power 3502I AP, which requires imput 48V and .35A. from the bag of Air-PWRINJ4, it indecates that the 3500 series is also included.

HI Scott, thanks for the reply, I have tested it works fine, but what will happen if we plan to use it for long run, does it will demage the APs?    in the packaging bag it says: Power Injector - AP 1140/1250/1260/3500 Series - SPARE
on the site I am setting up the AP, there is no POE switch and I don't have adapter with exact output for APs.

Power injector compatibility - air-pwrinj4

Does anyone know if the air-pwrinj4 (power injector for the 1250 and 1140 series) will power a 1240 and/or 1210 series AP?

Great, this will help with an AP upgrade this weekend. Thanks!

Power Injector AIR-PWRINJ1500-2 LEDs Continously blinking

Hi,
I am facing a strange problem with the AIR-PWRINJ1500-2.
At times the injector behaves perfectly fine but once Switched Off & again Powered On, all 3 LEDs, never become stable & blink continuously.
Has someone seen such a behavior ? Pls, share.
Thanks in advance.

Hey Ahmed,
My understanding is the power injector is not supported for the 1552CU and your only powering options are the following:
1552C/1552CU
• 40-90 VAC, 50-60 Hz, quasi-square wave, Power over Cable
• 12 VDC

BR1310 power injector red when power is removed, and restored.

Hello,
Have a set of BR1310G-A-K9-R with AIR-PWRINJ-BLR2 injectors, feed by P/N 34-1537-02 REVA0.
If 1310 connected to injector, powered by the transformer (mentioned above)when power applied, red light between power plug and coax connector is red, no lights on back of 1310. If I then disconnect the power plug from the injector, and reconnect, same light turns green.
Any suggestions? I didn't purchase the equipment, perhaps the parts listed above are not compatible?
Thanks for any help,
Jeff
Edit missing number.

Check for loose connections.the maximum distance between BR1310 and power injector is 100m.If this doesnt work Try to replace the power injector and see if it works.Perhaps replacing the power injector mostly would resolve.
