POE Injector for AP541N

Question, for the AP541N
wireless AP, what POE injector are you supposed to use?
The web site states any enterprise class af POE injector will do, but the AP1131 POE injector does not work with the AP541N.
Thanks!
Jeff

If you are looking at buying the switch just for the 1 access point, I would look for one of our small unmanaged switches. If you are just using the access point for general wireless connectivity, I would look at the SD208P. If you are wanting to use multiple SSIDs separated on different VLANs then I would look at one of our Small Business 300 Series Managed Switches with PoE, for example SF302-08MP.
The PWR-INJ4 was mentioned earlier, while that may work, (supply enough power to power the unit, please be mindful of the power requirements and not to over power the unit) that Enterprise device was not made specifically with powering any of our Small Business class devices in mind, so that combination has never been tested and validated.
I hope this helps, if you have more questions I am more than happy to answer them.

Can i use this PoE Injector for Cisco Aironet 1602?

Hi, i want to inject PoE to my new AP (Aironet CAP1602i) and i'm looking for injector, i found this one in my local store: : http://download.level1.com/level1/datasheet/POI-2002-V1_SPEC_V1.0.pdf
will it work? i'm afraid of the voltage. it specified 54V on the datasheet, but i understood that there is a PoE power negotiate.
Please advise.
Thanks,
Shai

The image of the injector? i've posted the datasheet, it has all the relevant information and i hope you can look at it.

Hi [email protected], what country are you trying to use the injector?

PoE injector needed for WAP4410N

I bought 2 WAP4410N wireless routers but it did not come with a PoE injector. We do not have a PoE capable switch. I have a couple of 3COM PoE injectors but am concerned about differing PoE standards could cause the 3Com PoE injector to damage the WAP4410N.
I cannot find a PoE injector on the Cisco website. Can anyone provide the Cisco part number for a PoE injector for the Cisco WAP4410N or provide assurances about the 3COM PoE that I have for the 3COM 3CRWER100-75 access points?

Rob,
Thank you very much for your quick response. This is exactly the
information that I needed!

PoE Injectors and distance limitation

Greetings,
Do Cisco PoE injectors for 3500 APs and 1552e APs act as a repeater? Another words, can we run 100m cat5e from the network to the injector and then another 100m from injector to the AP?
Thanks in advance!

Hi Scott,
I am not sure I understand. The ethernet to the AP traverses the injector, so I could interpret your answer as "Yes, you could dod 100m from the switch to the AP".
My setup is:
Ethernet switch === 100m ==== PoE Injector === 100m ==== AP
Another words my total ethernet run is 200m. This "should" work IF the PoE injector regenerates the signal, like a repeater. This is the piece that I do not know.
Thanks!

Power Injector for WAP200

Hello
I need your advice on whether power Injector for Aironet AP’s can be also used for SB WLAN products.
Is AIR-PWRINJ4= compatible with WAP200??
Any advice would be very appreciated.
Best Regards,
Allan Kim

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center.
Currently there are no Cisco/Linksys POE approved injectors for this device or any of our other small business products. Our recommendation for powering these units are to use either the supplied power adapter or a POE Switch that is 802.3af compliant. Any of our switches with a P in the model number would be perfect. Here is a link for you to our switches.
http://www.cisco.com/cisco/web/solutions/small_business/products/routers_switches/index.html
While it is possible for that Cisco Enterprise Injector to mentioned above should work, It has just not been tested so we can not completely recommend it.
Hope this helps.

Cisco PoE switch for WAP321

Could someone please point me to a Cisco small business switch that would be capable of powering five WAP321's?
I don't know the power profile on these APs but have noticed that the PoE injectors pump out 16.8 MAX watts. I can't find anywhere what the power profile is on WAP321 APs but ~17 WATTS seems to me to be quite high.
In fact, I was interested in the SF100D-16P which has a power budget of 64W over 8 ports... the price range is in my budget.
Could anybody tell my if the SF100D-16P can power 5-6 WAP321's sufficiently? Thank you.

The WAP support 802.3 AF. Although I don't know specific detail for the power profile I can assure it should not exceed 15.4 WATT. Typically the small business power draw is less than 8 watt per port. Devices which support CDP will also have a min/max draw that optimizes the POE functions.
However, the datasheet and admin guide does not make mention of any CDP

Confusion around PoE module for 800 series

There seems to be a lot of confusion around the PoE module for the Cisco 800 series routers
I'd like to know if the Cisco 887VA and 897VAW routers can have the internal PoE module fitted as an after sale item?
I see reference to 800-IL-PM-4= but searching for that amongst suppliers seems to show an external Power injector that connects to 4 Ethernet ports on the router and then from there you connect the external devices.
What I want to get is the internal daughtercard that adds PoE to the router itself.
Can anyone help me identify the right part please?

You can get the PoE daughter card pre-fitted before the appliance leaves the factory or you can do it yourself as an after-sales item.
800-IL-PM-4 is the daughter card. Read the Q & A below:
Q. Can the PoE be upgraded after ordering?
A. Yes, you can upgrade the PoE on all models except the C892FSP-K9, which does not support PoE at all. For all Cisco 890 Routers, the product ID (PID) for the PoE upgrade is 800-IL-PM-4=. This PID comes with two power supply options: 80 or 125 watts. The older CISCO890 requires the 80-watt option, whereas the newer C890 requires the 125-watt option.
Q. Why do some routers use 80 watts and others 125 watts for PoE?
A. The 80-watt power supply is used in addition to the standard 60-watt power supply, so you will have two power supplies connected to the router. For the newer routers we combined these two power supplies into the one 125-watt power supply (hence we have a 4-pin connector). Both models support the base router as well as 4 ports with standard PoE.

PoE Injector options?

Just wondering what other people are doing for power in a PoE environment that doesn't use PoE line cards. We use 6509's for core layer and a combination of 4006 and 36xx series switches for access layer.
We have a very HIGH port count which would be expensive to straight up swap out. Cisco stopped selling the WS-PWR-PANEL, so I'm curious as what other solutions people have come up with.
At the moment, I'm looking at the PowerDsine 6548 as a possible solution since it's just not fiscally justifiable to provide a power injector for every user at the desktop level.

If you are looking at buying the switch just for the 1 access point, I would look for one of our small unmanaged switches. If you are just using the access point for general wireless connectivity, I would look at the SD208P. If you are wanting to use multiple SSIDs separated on different VLANs then I would look at one of our Small Business 300 Series Managed Switches with PoE, for example SF302-08MP.

PoE injectors usage

Hi, sorry for stupid question.
Can I use PoE injector (even a third party one) for connecting a PoE Cisco device to a Non-PoE Cisco switch? (Of cause if the power output is enough). Or there is some kind of limitations?

You should be able to.
The injector is just sending power down the CAT cable to the end device.
Thanks

1231A Access Point and 3rd Party PoE Injector

I have a TrendNet TPE-101I power injector and I'm trying to power a 1231A via PoE. The injector is 802.3af-compliant. Is there any way to make this work with a 1231 or do I need to go find a Cisco-branded injector for this model? I attempted to make a reverse polarity Cat5 cable yesterday, but that didn't seem to work. I am by no means a skilled cable-maker, so it may have been what I built. I crimped a standard 568B pinout on one side (WOr-Or-WGr-Bl-WBl-Gr-WBr-Br) and the following pinout on the other end: WOr-Or-WGr-WBr-Br-Gr-WBl-Bl. I know these APs were part of the nascent days of 802.3af, so given reverse polarity, what did I do wrong? Or is it simply not possible? -Chris

Chris, it appears you need to make a cable that has "straight-thru" data but "crossover power" looking at your wire color description.
I would suggest using two jacks with 24gauge wire between them instead of trying to crimp the RJ45 connectors for ease of rewiring.
Sounds like you are adapt at making cables so try this:
Between the jacks wire pins 1,2,3 & 6 together.
Then wire pin 4 on jack 1 to pin 8 on the other and pin 5 on jack 1 to 7 on the other to cross the power. Then wire from jack 2 to 1 the same way.
This should have the appearance of connecting the blue pins to the brown ones keeping the correct polarity.
Good luck.
Kevin

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:
http://www.google.com/products/catalog?hl=en&biw=1168&bih=723&q=cisco+AIR-PWRINJ4%3D&um=1&ie=UTF-8&tbm=shop&cid=1924636136971570879&sa=X&ei=oGf_TcGfHoy40AH2xLDjAg&ved=0CIMBEPICMAU#
should work, Cisco should be able to confirm . . .
If not then I would try:
http://www.versatek.com/products/cisco_power_injector.htm?_kk=cisco%20PoE%20injector&_kt=90d05a21-707c-456a-8dc9-c92b9a334f1b&gclid=CPnpz-nlxKkCFUqM5godGH4Mmw
I know your original post was in January and you may have created that 100m power cord but I hope this helps others.

390W PoE-Budget for Cisco 3650-24 Port Model

Can anyone provide a "show power inline" with the available PoE-Budget for the new Cisco 3650-24 PoE+ Switch? We have to be sure that the 390W from the Datasheet is 100% correct.
Many thanks
Manuel

I am not sure how many people have deployed 3650 series switches, as they are brand new. If you are not sure about the documentation, ask your system engineer to clarify it for you.

POE extenders for wireless

I have a park area that requires POE cameras for security and wireless coverage. It is an outdoor park and the distances in some places exceed 100M. I was looking at POE extenders, but have read the Cisco switches have an issue allowing the extenders due to time delays. Anyone have any knowledge?

May not work. This is because mid-span PoE is still limited by 100 metres standard. And, here's the kicker, extending the range doesn't mean you've extended Layer 2. If you go beyond 100 metres, with or without mid-span PoE, then you can be guaranteed your link may operate in 10 Mbps, half duplex.
If you want to extend the distance covered, then run a 90-metre copper run to the central location and install a PoE switch there. Take note, that the cable run is made out of COPPER. This means that if lightning strike on the switch won't just damage the switch but anything connected to this switch using copper. One way out is to use fibre optic run to span the distance so the surge of the current will not go back to the core.
