AP1252 poe
Hi,
My WLC is running code 5.2.178, and 1252AP with only one 2.4Ghz radio. I could not see the poe status indicator under wireless->ap->advanced.
From the 3560E switch, I could see the power drawn is 15.4 watts.
Question is, is there a way to force the AP to draw power @20Watts, cause when i try to connect. i only manage to connect up to 72Mbps.
Thanks
The command on the switch port is something like power inline static max 20. Make sure you have the right code on the switch that allows it. Don't know it off the top of my head, but I think th eminimum is 12.2(44)SE.
For 802.11N, you need to make sure that WMM is enabled, that you have bonded channels to give you 40mhz channel width and that you either have an open ssid or using WPA2-AES. WPA-TKIP is not supported for 802.11N.
When bonding channels in the 2.4GHz, you will have overlapping channels if you have more than one ap and is suggested that you only bond channels in the 5ghz.
Looks like your already running MIMO since you have 72mbps already.

AP1252 in dual radio mode with in-line power.
Hi,
Has anyone actually managed to deploy the AP1252s in dual radio mode and been able to power via a POE device?
The information regarding max power supplied is misleading.
For example, the 6500 802.3af POE line cards appear to only provide a max of 16.8W (from the 12.2.33SXH2 release notes).
The 4500E with the new enhanced POE line cards can apparently provide 20W with 12.2.44SG release.
The 3560E/3750E documentation is contradictory - early bulletins state support for Enh POE and then the more recent notes state that it is not supported.
Any real world experience of this issue would be greatly received.
ThanksWhat you have here is correct. 6500 with a sup720 and 12.2.33shx2 will only provide max of 16.8W. The E-Series can provide the 20W max as long as you have the correct code.

AP1252-AG with Cat 3560 / Cat 3750
Hi All,
please advise, I am probably not the only one, but I have come to realise that 15.4W provided by switch ports on 3560/3570 catalysts is not sufficient to power up an AP1252-AG dual radio device. I have read the spec and it says that a dual radio AP requires 16.9W, but a single radio AP will consume/need 12.95W plus a little more depending on the ethernet cable length. As a test I physically removed one radio from the AP1252-AG and tried to power it up via poe port on switch. The AP powered up OK with just one radio module installed.
However the AP cannot be installed with one module removed, so my alternatives are to either power the AP with direct power supply or use the Power Injector which will provide enough power to start both radios.
I was wondering whether it is possible to have both radios installed 2.4/5.0 Ghz but have one disabled through the software, so that the AP will only effectively be running with one Radio Module (UP), but it will have two Radios installed physically.
I have tried this numerous times, when I try to use poe for the ap, it negotiates with the switch port that it need more power for the two radios, the switch can't provide it so it goes into low power mode.
I was hoping that by disabling one radio and then booting the AP it would only request enough power to feed 1 radio, the switch would be able to provide the requested amount and then the AP would work. But I cannot get this to work, Is it at all possible?Well yes, if the clients are in range of the same AP, they will use the AP to communicate with one another. But if you have several APs, say one AP in one room and another AP in another room, then usually signal travels from wireless client 1 to AP 1 via the radio, then AP 1 forwards the packet over a cable to a switch that relays to the second AP, then the second AP relays the signal wirelessly to the second client. This system is used because usually APs would not use their radio to talk to each other, for many reasons.
In your case, if you have a controller, Aps need to talk to the controller, and the controller doesn't have any radio anyway, so you need cables to connect to your controller. If it is a 2100 controller, you can forget the switch and connect your APs to the controller.
If you have a 4400 series, you need a switch as APs cannot connect directly to 4400 controllers.

Is anyone aware of a Gig fiber to copper POE injector for a AP1252 that meets the 18 watt requirement? Our infrastructure is all 62.5 fiber, and the APs will be over 100 meters from the switches, so I need a media convertor, and injector to make the conversion. Thanks.
Check the data sheet and ordering guide of the 1250 AP. It should hold the information about the device.

How to make a report in RME to display all POE capable devices
Hello,
I need to create a report that will list switches in my network that support POE. Most of our switches are 3750 stack and I know most of them have POE capabilities but whenever I generate the report under RME POE Port Level Report or POE Report it gives me an error that says none of the devices are POE capabled/enabled.
Does anyone know how to generate this kind of report? I tried making a template but I still couldn't produce the result that I need.

Hello,
I have a question regarding the power consumption of a Cisco 2951 router with an AC-PoE power supply (without PoE boost).
In fact in the table (n°7) of the Cisco 2900 Series ISR (G2) datasheet, that sum up the power consumption data for Cisco 2900 series routers there is the line : "Maximum Power with PoE Power Supply (Platform Only) (Watts)", and I would like to know what is exactly the meaning about the mention "Platform Only".
Thank you for your help, best regards,Hi @francois.trarieux,
This is the maximum power that is consumed exclusively by the router from the PoE PS (Power Supply). The power capacity that the PoE PS gives to other PoE devices (IP Phones, Cameras, APs, etc) is specified in the line below "Maximum End-Point PoE Power Available from PoE Power Supply (Watts)" of the datasheet.
HTH.

POE device flapping on switch access port
I have a switch at a remote office. I have a Cisco 2851 Router and two cisco 3650 POE switches. I also have three Aruba 105 POE APs. Two are plugged into one switch, and one into another. Yesterday we had a power issue that caused all of the equipment to reboot. Everything came back up fine except the two Aruba APs that are plugged into a single switch. The other AP came up fine. When I do a show power inline, the two APs show that they are getting power from the switch.
Interface Admin Oper Power Device Class Max
Fa0/1 auto on 15.4 Ieee PD 3 15.4
Fa0/2 auto on 15.4 Ieee PD 3 15.4

When I do a show mac-address-table, I can only see the two missing APs for the brief moments that the interface is up.
What I'm trying to find out, is can this still be a part of the running configuration that never got saved or did the power disruption just cause a hardware/cabling problem?Unfortunately that's not an option here unless I ship mine out and walk a standard non-technical user through the process. But I will tell you that we moved the AP that was in port one into several other ports on the same switch with no response from the lights, show power inline command, didn't show in the MAC-address-table and then it finally worked on port 31. We moved the AP that was in FA 0/2 into several other ports as well as replaced the cable between the switch and patch panel and the only thing I show is that it registers under the show power inline command, but no light on the port and nothing in the mac-address-table. The AP is located in the ceiling so replacing it will be a last resort.
Basically I'm wondering if the device is showing power but not mac in the address table, does that demonstrate that the layer 1 is working correctly? -

SLM224P POE issue after power outage
Have recently experienced an issue where after a power outage, the device recovers with the exception of the POE ports. This device supports POE on 12 of 24 ports. I have two wireless radios (currently, with plans to expand POE need) on port e1 and e18 (poe is on 1-6 and 12-18). The devices on the non-POE ports all came back up fine following the outage, but the two radios remained inactive despite what the port management details indicated. The java indicatons indicated the ports were down, contrasting the port detail page. There was no power on either port. I recovered by logging into the unit and instigating a reboot at which point all the devices came back.
This is the second time that this has happened, the first time being written off as a fluke. I consider this a pretty serious flaw as the POE aspect is just as vital, if not more so, than a standard non-POE port recovery. The unit is on a UPS, but the outage exceeded the battery duration. The device should recover all operations automatically, without any human intervention. I see that the SRW224P also has similar issues.
There also appears to be a bug in the time setting routine. In some instances I keep getting a message indicating that the time must be later than the time being set...due to the daylight savings time. Turn this off, then set the time and then turn back DST back on. A NTP (auto) server setting would be nice.I would like to think power could be a factor as a reboot did recover the device, but as stated, it was on a UPS. Granted the battery had depleted and I guess a disturbance might have gotten by (maybe on the power-up cycle), but the device did function fine on the non-POE ports. Seems to be more of a device issue in its ability to recover and know that it has done so correctly. I like the device, just scared as I can't control when an outage or disturbance might occur and the management interface indicates the ports are up when in fact, thay are not. Thanks for the thought though, I will at least try a different make UPS.

Adding a PoE Switch to existing Network
Hello,
Currently we have a Linksys RV016 router with 3 Linksys SRW224G 24-Port Managed Switch. Can I add a PoE switch to my existing setup without any problems or I can only add none PoE switches?
If I can add a PoE switch is there a specific configuration or just plug and play?
Thanks,
BYes you can connect a PoE switch to the SRW224G switches but you will need to connect the PoE switch to a power supply. The only way that PoE (Power over Ethernet) will work is when you connect the PoE switch with another PoE switch. Only in this scenario, you won’t need to use a separate power supply for the PoE switch to work because it is getting its power form the first PoE switch / router.
Regarding if this will just be plug and play, it won’t be plug and play. If you have set up VLANs or other crucial settings in the other switches and you want it to manually set the PoE switch depending on the limitations you want for these PoE switches. -
A rugged switch that can support PoE+ on 4 ports
We are mounting 4 Access points in a parking Lott. We have wired up a cat6 cable to each AP (not power). The cat6 cables are terminated in a weather resistant outdoor box.
My question is: Does Cisco have at rouged switch that can support this setup?
The plan was to use a IE2000. However the IE-2000-16PTC-G-L that we purchased, did not deliver enough power on each port (it can deliver PoE on 4 ports, but only PoE+ on 2) My fault that I did not read the PDF thoroughly enough :-(
So question is, does cisco have a rugged switch that can deliver PoE+ on 4 ports?I believe you'd have to move up to the IE3000 series with the 8-port module (Cisco IEM-3000-4PC-4TC=). That module will deliver POE+ on 4 of its 8 ports. Reference.

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,
lachapelleHi 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. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

Ethernet Ports
The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.
Power
The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.

In the properties of our AP1131 under the advanced tab there are poe settings. I have up on this. Most of our AP1131 are powered by Cisco 3750 switches. A few are power by Cisco poe injectors.
What are the purpose of those poe settings for the AP? How would one set them for a 3750 attached AP versus one with a poe injector.Hi Craig,
The settings are described in the attached dos;
The 1131 requires either IEEE 802.3af power or needs a setting on the WLC for using power injector or Cisco Pre-Standard PoE. Our older switches could only provide Cisco Pre-Standard PoE so we had to tweak the WLC Power setting for these AP's. Once we did that the Radios came right up. Here is a reference;
You may have to enter the following info in the WLC;
While the AP boots, with its Intelligent Power Management feature, it negotiates with the switch via Cisco Discovery Protocol messages in order to provide the necessary power to the AP. Even though the power injector is connected to the AP, the AP that uses this Intelligent Power Management feature gives priority to the Cisco Discovery Protocol information in order to identify whether or not the switch can provide the power. Therefore, after the Cisco Discovery Protocol message shows that the switch does not provide sufficient power (since it is not an inline power capable switch), the AP disables its radios. At this time, the status LED of the AP turns orange and this error message is recorded:
[ERROR] : AP has not enough in-line power
to enable radio slot 1 In order to overcome this problem, issue the
config ap power injector enable installed
command on the controller that is connected with this AP. This command is available from controller version 3.2.116.21. Ensure that you use the correct version in the controller.
This command specifies that a power injector is used in order to supply sufficient power to the AP.

Does anyone know the 15.4W output power per user port in the current 802.3af is the min. or max.? I've seen conflicting info on different vendor's spec sheet. If it's the max., then why are some "802.3af" injectors outputting as much as 1A.
it is the max. 1 A POE can power multiple equipments.
