• Cisco 1252 s with regular 802.3af PoE switch - what are the impacts?

  Does anyone have an experience of real life to the deployment of the 1252 s on 802.3af regular PoE switches?  I have a few 1252 s a certain ports PoE 3560 and issuing upward with alarms 'low power '.

  I wonder what the impact of the real world with this scenario.  The 1252 s have both 2.4 Ghz and a radio-5, 0 Ghz in them and I have HT enabled on the controller.

  I wonder what capabilities I lose by running on 802.3af food in addition to the inconvenience of the alarms.

  Thanks in advance!

• IEEE 802.3 af, options of distribution of power on Cisco products

  Hello world.

  IEEE 802.3af - 2003 described five 5 classes of power a device can belong to. It is worth noting that this isn't

  required that a seller of PSE implements classification of power, as these classifications are optional.

  Cisco implements this option in its IEEE - 802.3af - compliant device PoE (ip phone. AP, etc.) ?

  (1) cisco has adopted a cautious approach to the allocation of the authority by which the PSE will allocate either the IEEE 802.3af standard class, the Cisco Discovery Protocol negotiated value or 7W per device, the discovered device.

  (2) what is the default if we have a switch compatible cisco 802.Wireless af and cisco 802.3 af compatible peripheral PoE IE will allot of power using the classification of power or uses CDP to allocate the desired power or simply allocate 7w?

  Thank you

• 1130AG Radio will not allow.

  So no Rabbit trail, point line 18 above is because I use a (non-Cisco) POE injector which IS 802.3af compliant. (http://www.engeniustech.com/resources/NPE-4818_PoE.pdf).  It's cheaper than buying a POE switch (Cisco or otherwise) for a single POE device in the remote office to both users. ($21)

  The device connects to a 3com switch (after crossing the POE injector).

  TAC said the guarantee missed last month (May), and I could do either unique suppport @ $400 / hr, or probably better to buy a new.

  Before buying a new, what might I be missing that could solve this problem?

  Thank you

  James

  You have a problem with the firmware of the radio.  You can see with rcore files generated and the mac address of the radio is showing that all zeros.  You could try to load a different version of the code to the AP.  It would put a new radio on the AP firmware file.

• Injector POE 10 SX20 and tactile

  Hi all

  Tap 10 includes POE as Touch 8 injector?

  If this isn't the case, when we use 10 touch with the SX20 and there is no switch POE, CTS-POE-NIJ is necessary, I guess.

  But we can control CTS-POE-NIJ separately on CCW, so if you forget to order CTS-POE-NIJ with SX20, what can we do?

  10 Touch works with standard POE injector like that?

  http://www.TP-link.com/LK/products/details/?model=TL-POE150S

  Kind regards

  Kotaro

  None of the documents I've seen says that the PoE injector comes with the Touch 10.  Because they were originally designed for the MX series include the port 10/100 PoE to connect to and the SX10 compatibility and SX20 has been a recent addition of compatibility (in TC7.2 +), I guess that if you ordered one, it would not come with the PoE injector.

  The only documentation of note that I found (the SX80 administrator guide) says that there need to be a Midspan PoE injector, or to power it with a PoE switch.  So, any 802.3af injector that works with Touch 8 should also work fine for 10 touch.  (And Yes, a quick glance at the specifications, the device of binding TP that you linked seems to be a device that would work).

  You can probably order the good injector PoE of CIsco on CCW, you just find the correct part number high range - similar to the additional licenses for endpoints - these can be a little hard to find if you don't know the right of departure (and, no, I don't know where to find the PoE injector but maybe someone else can help).

  Otherwise, you can wait a few months and you will be able to pair it directly via the USB port (the TC7.3 release notes: "A Cisco adapter USB-to-Ethernet brand will be available in March 2015").

• C1250 AP required using POE power

  Hello

  I have questions about the AP C1250.

  -What are the energy needs POE for the AP and the Cisco 3560 and 4900 is the correct POE power to support?

  -Also, should I get the injector of power to power the switch online usage? Another word if PoE, can I connect the Ethernet cable between the switch port directly into the Ethernet port on the AP without the power injector?

  Really enjoyed for more information.

  1250 with a single radio or 802. 11A / n and 802.11bg / n

  15.4

  1250 with two 802. 11A / n and 802.11bg / n radio *.

  18.5W

  Basically you can use the 802.3af switch power to 1250, as long as you have the intention to use only 1 radio. If you did, it there would be no power injector and here for the AP could have just an ethernet cable from the ap to the switch.

  However, if you plan to use two radios, power exceeds 15.4 (802.3af maximum) which means that you will need to use a special power injector for it or the power room. Otherwise, I think that there are a few switches that support this 'high power' mode, but I don't know what they are...

• WAP321 - power

  Hello!

  What is the power required by WAP321? There is no information on the standard IEEE 802.3af class to the datasheet.

  Thank you

  Leonardo.

  Hi, my name is Eric Moyers. I am a network Support Engineer in the Cisco Small Business Support Center. Please use the Forums to Post community of Cisco.

  If you look at the data sheet attached to the WPA321 to the end, inside table 1, there is a section titled PoE.

  PoE

  802.3af PoE: PoE 10.6W peak power

  It is the most power you expect WAP to draw. So, as long as the switch can provide at least a lot more current, you should be fine.

  Thank you

• SG100D - 08 p - how much power per port?

  Hi all.  The Cisco documentation goes on to say '33.6W' dedicated power budget.  I'm new to PoE, but what this cdoesn can't answer is if you can get all the 33W on e to asingle port if you want to, or is it a share of about 8. xW by port.  I would like to connect an AP541N for example, which has a maximum circulation of 9.9W, so a single port on the SG100D - 08 p must support that much.

  I'm sure that PoE is designed to facilitate a port unequal distribution else you would be stuck with a single type of device on all ports of a same switch, but I want o confirm if I can.  Thank you!

  Hi, the Valley of the switch cannot provide more than 12.95 Watts per port. 802.3af specifies 15.4 watts which results in maximum actual 12.95 per port.

  The maximum budget would be 33.6w for the switch set in the 802.3af parameter.

  It can supply enough all class 3 poe (up to 3) device and enough power up to 8 class 1 device poe and 4 class 2 poe devices

• SG200-08 (SLM2008T) - is there a PD power option?

  The original SLM2008 had the ability to be powered by PoE - DP 802.3af on port 1.

  This option is always available on the latest SLM2008T? I can't find what he mentioned in the Cisco documentation.

  Web sites of some providers online States that it is an option, but I don't know if they have just updated their contact information to reflect the new model.

  Happy new year to all.

  Hello kmccourt,

  I checked it for you and found that the SL2008T has a PoE in the port. It can be powered by PoE on port 1.

• 1400 series 802. 11 a bridge with Catalyst 3524 switch?

  According to the documentation below, "you cannot provide redundant power to 1100 and 1200 access points with the two power DC to its port and inline power from a patch panel or powered switch to the access point Ethernet port'. How about the 1400 series bridges? You can use a power injector to power and also connect it to a catalyst 3524 switch (WS-C3524-PWR-XL-EN)? He will know not to draw power from the switch? Or should it be plugged into a hub, and the hub plugged into the switch? Or what would be the recommended configuration? 3524 switch already has 350 access points and a trendy 350 bridge. What would be the risks, if any, plug the bridge 1400 series also in the switch so that it is also a power injector-shoot?

  Thanks for the tips!

  Use the power only one Option

  "You cannot provide redundant power to 1100 and 1200 access points with the two power DC to its port and inline power from a patch panel or powered switch to the Ethernet port on the access point. If you are using power to the access point from the two sources, the switch connection control panel or power could close the port to which the access point is connected. Figure 1 illustrates the configuration of power, which can stop the port on the Panel of brewing or powered switch.

  "Figure 1 bad power Configuration with the help of two Power Sources

  "Operating Radio 5 GHz requires power injector, power Module or Catalyst 3550-24 PWR Switch

  "The series 1200 power injector and power module support operation 1200 series of the 5 GHz in the access point radio." Currently, the Catalyst 3550-24 PWR switch supports power for radio 2.4 GHz and 5 GHz radio. other switches and power patch panels could provide not enough power for the 5 GHz radio.

  "Access point requires 1200 Series universal power supply and power injector.

  "The 350 series universal power supply and power injector are not compatible with the 1200 Series access point. If you use a power injector or a power module to power a series 1200 access point, you must use a universal power supply series 1200. If you need to use an injector to power to inject into the access point Ethernet port, you must use a power injector 1200 series. »

  The power injector is between the switch and access point online. If your power injector fails, you have lost connectivity to the switch anyway. And to power from a device to a switchport works only if they are directly linked together; You can't have any other intermediate devices in the path.

  In short: No. is not a matter of being a bad idea, it is not be possible to try again.

• Feed an AP1132 with PWRINJ4?

  Hello

  I have a question of compatibility with PWRINJ3 and PWRINJ4, here is my situation.

  I have the material in my company:

  -AP1130 and PWRINJ3 (and I have no spare parts left for the power injector)

  -AP1142 and PWRINJ4 (I have lots left spare parts...)

  Recently, a PWRINJ3 stopped working and I was wondering if I could use a PWRINJ4 to power an AP1132?

  In the cisco docs, this power injector is not marked as compatible, but given that these AP are marked as consistent 802.3af, seems would be reasonable to think that these power injector uses this standard to power the access point.

  But since I'm not sure of this fact, I would like your opinion on that.

  Thanks for the help

  Cisco docs:

  PWRINJ3: http://www.cisco.com/en/US/prod/collateral/wireless/ps7183/ps469/product_data_sheet09186a00800f927d.html

  Hello

  I believe that the years 1130 are not compatible with PWRINJ4.

  PWRINJ4 is used to supply APs as the years 1140 and 1250 s 3500 series

• AIR-AP1231G and PoE

  Evening,

  I have a number of AIR-AP1231G scattered in my factory. All are fed power inline injectors and are working properly.

  I am wanting to buy a number of PoE switches that will have the task off the injectors inline for an easier game to the top.

  I bought a Cisco 300 Series 10 Max PoE Switch port, however the AIR-AP1231G won't start when you plug into the switch. No light on the switch or the AP.

  Oddly enough, I have an AP1242G AIR of what powers well without any problem of the switch.

  Is there any configuration, I need to do on the access point so that it can turn on from the switch? The datasheet of the switch indicates that it is 802.3af. I tried the access point on the 10MP models of 28 p of the 300 series and no go.

  Can someone tell me please in the right direction? I'm really lost and PoE is slightly beyond me at the minute.

  Hi Tim,.

  You are welcome

  Yes, it's worth a try. The 1230 is shown as it is supported.
