• 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!

  Hello

  This is the command question... the AP 1252 switches POE needs improved Ex-3750-E for all operational radios... If we use only a 802.3af while a single frequency can be enabed and her we can't get a rhythm N... the link below will explain better...

• Maximum power PoE switch SG100D - 8 p

  Hi all...

  Help, please

  How PoE power of SG100D - 8 p?

  its port 8 all support PoE?

  Kind regards

  Leonardus

  Hi all

  I wrote to the product manager switch (MP) and requested a document. He continued with a few detailed characteristics indicating the budget POE of 32watts spread over the ports 1 to 4. However, my statement above is correct.

  A section of this document that the PM has sent me, is copied below.

  

  Can't blame leolaohoo for being confused, because I think not publicly in the face of a document which indicates the power dedicated to the POE ports on switches in the 100 series.

  When leolaohoo States in a question in a previous message and request confirmation, "basically what Dave said is that the switch can provide up to 8w of PoE power." my apologies for any misunderstanding.

  The unmanged 8-port POE switches CAN provide up to 32Watts of POE power spread over four ports.

  Best regards, Dave

• WAP321 Cisco PoE switch

  Could someone tell me please to a small businesses of Cisco switch that would be capable of powering of five WAP321?

  I do not know the power on these access points profile but have noticed that the PoE injectors pump 16.8 watts MAX. I find anywhere what the power profile is on WAP321 APs but ~ 17 WATTS seems to be quite high.

  In fact, I was interested in the SF100D - 16 p which has a budget of power of 64W on 8 ports... the price range is within my budget.

  If someone could tell my, if the SF100D - 16 p can power 5-6 WAP321 enough? Thank you.

  Hello Rob, the answer is Yes, the SG100D - 16 p will manage enough 5 AP.

• Aironet 2802i Radio0 has not started, not enough power POE on SG300-28PP switch

  When I restart Aironet 2802i which is powered by 28PP SG300 28 - Port Gigabit PoE + switch, I saw the following message:

  [* 13:47:31.8044 26/09/2016] Radio0 has not started, not enough power POE

  Series Aironet 2800 get started guide mentions "any 802.3at (25.5 W) compatible switch port" and SG300-28PP seems to be consistent.

  Please advise, thank you.

• Are there plans for the new ESW 500 models switch with PoE capability?

  I know that current models of ESW 500 switch don't have enough capacity to power all the switchports to 15.4, even if the ESW-540-8 p model has almost enough capacity to power all the switchports to 15.4.

  Reasons why new ESW 500 switch with PoE capacity are necessary:

  • The existing PoE 500 ESW switches have not always enough when these devices are deployed with the UC500:
    • 7945, 7965 and 797 x phones
    • series phones (not yet supported with the SBCS solution) 9900 and 8900
    • PVC2300 Surveillance Cameras
    • AP541N access points
  • The UC560 comes with all the PoE ports and requires at least an ESW switch be deployed
  • Version 48 ports gigabit switch ESW is currently available only in the version not PoE, and we need a version of 48 gigabit ports for users of the UC560 solution.

  Existing ESW 500 switch PoE capabilities are:

  • ESW-520-8 P: 60W
  • ESW-540-8 P: 120W
  • ESW-520-24 P: 180W
  • ESW-540-48P: 380W
  • ESW-540-24 P: 280W

  PoE of ESW 500 switch capabilities supporting 15.4 full power on all PoE PoE ports are:

  • 8 port: 123.2W
  • 24 port: 369.6W
  • 48 port: 739.2W

  Are there plans to release the new ESW 500 switch models increased capacity, enough to supply the full 15.4 to all PoE ports with PoE?

  Hi John - Thank you for your participation in the small community of business support. I talked to our switch product manager and want to share his response.

MsoNormalTable {mso-style-name: "Table Normal" "; mso-knew-rowband-size: 0; mso-knew-colband-size: 0; mso-style - noshow:yes; mso-style-priority: 99; mso-style - qformat:yes; mso-style-parent:" ";" mso-padding-alt: 0 to 5.4pt 0 to 5.4pt; mso-para-margin: 0; mso-para-margin-bottom: .0001pt; mso-pagination: widow-orphan; do-size: 10.0pt; do-family: "Times New Roman", "serif" ;} "}

  We have taken the conscious decision to deliver PoE as ESW and other switches for small businesses for several reasons:

  • Endpoints PoE more attract a lot less than the 15.4 W maximum power. Most IP phones are below the range of 7W.
  • A typical deployment would most PoE devices connect to a switch.
  • For these reasons, the ESW is not burdened cost with the PoE feature which would not be used most of the time.
  • All ports are still able to PoE you can connect up to 24 devices PoE Switch 24 ports to any point in time, as long as the handset is in the title of the budget.
  • Therefore, given that these products are intended for small business and the price is an important factor, we opted for this approach.

  We do not have a product at full power on all ports in the Cisco Small Business portfolio, except in the arena of 8 channels. Within Cisco, Cisco Catalyst products support this today.

  Thanks again for the question,

• GS728TP: PoE fault

  Hello

  We just purchased a Smart GS728TP PoE Switch.

  Unfortunately, when we plug in a new device requiring of PoE, the switch must be rebooted before will recognize (and power) of the new device. It works without problem once this has been done.

  I raised a support ticket and Netgear advised me, it must be a hardware failure on the device. They suggested that I return to the vendor.

  My initial intention was to buy a GS724TP, but was apparently it is now obsolete and the GS728TP was a direct replacement.

  We also have a GS748TP (purchased at the same time), and it works without any problem of PoE.

  Has anyone encountered a similar problem?

  Maybe I missed something obvious in the configuration. However, I have done a factory reset (and also waited 20 minutes to see if the switch recognizes the device without having to reboot).

  Many thanks in advance,
  Stephen

  Hello

  I am very happy to find a topic referring exactly the issue I encountered.
  I also received a replacement switch put the problem was always the same (latest firmware from the website, etc...).

  After hours of troubleshooting, I discovered that it is related to the switch cascading behind it.

  This GS728TP was connected on a GS724TP, both are POE switches, I disabled the POE feature on the two switches on the ports used for them and no problems cascading more.

  I don't know if you've had the same configuration, but in my case, it is now resolved!

  Kind regards.

• Linksys LGS308P passive POE 24V

  Hello

  I plan to buy Linksys LGS308P work with Ubiquity UniFi PSU-AC-LITE which is powered by passive POE 24V.

  To the profile for LGS308P I can't determine if it also supports passive POE 24V.

  Anyone know if this combination is possible?

  Thank you

  Pavel

  Linksys genius come back to us and the LGS POE switches do not support the 24V they mention is not compatible with PoE IEEE 802.3af / standards.

• 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").

• SG200 or SG100 switches of the series?

  Hello

  I am helping a company data selection switch and VoIP for a small company of about 40 users who is penetrating new spaces and adding VoIP.

  The subnets of voice and data will be routed to the other.  No VLAN or QoS are necessary according to the VoIP provider.

  They need ports gigabit PoE 22 for phones and no PoE ports of 40 +.

  The part-time computer scientist on the spot has no experience in the management of the switches.  So, they think about the use of six switches of SG100D - 08 p unmanaged for the PoE ports with all what SG100 switch to non PoE ports.  However, it seems that both switches of series SG200 (SG200 - 50 p and SG-200-50 or SG200-26), would be easy to set up for this purpose and require little management.  They have most of the equipment rack mounting.  It seems that SG200 switches would solve what could be a mess of this and son with six SG100D - 08 p of

  I understand that little, if any requirements for a non - PoE switch SG200-xx. Is this correct?

  Can someone please comment on how the SG200-xxP switches are easy to use and advice or suggestions?

  Thank you

  Caseranch

  Hi Caseranch, please consider that SG200 switches are not POE on each port only 1/2 of the ports. At a switch 48 Port POE 24 ports. I know this should meet your requirement, but for the future expansion of POE, another POE switch.

  You're right, in this sense, the SG200 needs very little to zero configuration. The only thing I recommend is if you buy a switch to manage, upgrade to the new firmware, factory reset the device and then install and connect things for her. This should be sufficient based on the way you describe things.

• Failure of poe SG300 - 28 p

  Hello
  I am in possession of a switch SG300 - 28 p
  I'm having trouble with poe power access point Netgear WG102
  Can you tell me if the two devices are supported?
  Thank you

  Hi Luca, looking at the site of Netgear access point is eos/eol

  http://www.NETGEAR.com/business/products/access-points-wireless-controllers/access-points/wg102.aspx#two

  He says that the product is no longer available and to look for the WG103.

  View product say it's compatible 802.3af

  Integrated IEEE 802.3af Power over Ethernet (PoE)

  Have you used this front access point? In an environment of production at one point worked with POE? When did you start to use the SX300 switch? Is the SX300 on the latest software? Do you see an indication of the State of the connection of the switch (orange or green light)? The access point works with a power adapter? Do you have any other switch POE try with? You have all different POE switch connect devices that work?

• Questions SG200 - 50 p and PoE

  Community,.

  I just bought a switch SG200 - 50 p to replace a WS-CE500-24LC, who had a limited duration (4) PoE ports.  I was running points of access Cisco 7940 IP Phone, Cisco AP1231 and AP1100 via PoE out of this switch.

  When I try to connect these types of devices in the SG200 - 50 p they don't feed upward.  What is going on?  Why these devices (IP phone 7940, 7960, phone IP, AP1100 series access point, AP1231 series access point) do not get PoE switch SG200 - 50 p?

  Is there a setting to allow these devices to receive switch PoE?

  Thanks for your help.

  Hello

  The modern series switches SGx00 accept 802.3af compatible devices.

  A coursory look at these devices, they are pre standard POE.  Check the URL of questions below for answers regarding at least the phones.

  But no where in the datasheet for the AP1231 I see that the AP 1231 is compatible 802.3af.

  There is a solution in the URL below, that is to choose a switch that can provide standard and compatible POE.
