POE problem

Hi forum,
I have a site using mitel IP phones plugging to cisco 3560xl with POE support.
If we plugged the mitel phone into the switch port there is POE support, but if we plugged a PC back and remove the mitel phone, and after that plug the mitel phone directly to the port again, there is no poe except unless we shut and no shut the port.
why is this so?
Thanks much,
py

1130AG Access Point PoE Problem with Cat 3750G-24PS-E switch

I am having a problem on the PoE negotiation of Catalyst 3750G-24PS-E and 1130AG Access point. I used straight and cross cable for physical connection since by default the auto mdix per port of the switch is enabled/on. I used CLI, CNA and Web Device Manager on both devices to isolate and troubleshoot the problem but still the PoE negotiation on both devices won't work out. But when I used the access point into other switch (CE500 PoE Switch), the access point is working properly. Does anyone can help me to distinguish what the problem really is? The IOS Version of 3750G switch is 12.2(25) SEE2 and the 1130AG access point IOS Version is 12.3(8)JEA.

Hi Rob,
Thanks for your reply. Yes, I tried shut/no shut on the switchport many times. I saw that the switch grant power inline on the port but the port still can't/won't provide any power to boot up the access point.
Thanks,
Nelmar

PoE Problem with SRW224P

Good morning everyone,
I have 15 of these switches used for a Voip deployment.
At one point, there was a power failure on one of these, and when it turned back on, the phones didn't power up.
The switch was fully operational.
As I logged in to the switch to check PoE port config, everything was enabled, yet everything was still off, including the PoE lights on the switch. When I clicked submit on that screen, everything powered on.
This happened at least 3 times, and Linksys suggested we change the switch.
Now, this happened on another switch. We tried many different firmware versions, and we always have the same problem.
Has anyone experienced something like that?

Got the exact same thing, I thought the VoIP phones were the issue, but I got new phones just today and those don't work either.
So the switch's POE just died after a power failure...

POE Problem with SG200-26P

Having an odd situation with this switch. Set it up with two vlans and everything was gread for about 3 days then over the weekend something happened. One od the POE Phones a Cisco IP Phone 7960 started making an odd buzz sound while hooked up to port 13 on the switch. To aliviate the problem I switched the port to 14 for that phone. The buzz went away and the phone powered on. Started looking into the problem with the port and could not find any obvious problems with the port so deemed it to be a bad port. The next day the phone that was hooked to port 1 was randomly rebooting so looked into this port and while trying to find a port that worked found that ports 1-6 would not turn on the poe light on the switch and would not power the phones for a very long time without the phone rebooting. I did however find that ports 14-18 however work as they should. Is there something I am missing as to why or how ports 1-6 are not turning on POE and could they be related to the problem with port 13? Any ideas on how to fix this problem. Currently on firmware version 1.3.5.58 and boot version 1.3.5.06. thank you for your time.

David,
This sounds like the switch is failing but I could not rule out a configuration corruption. I would back up the configuration, reset to factory defaults and test only the PoE functionality. If it works, recreate the configuration (VLANs, etc.) and confirm that PoE is functioning on all ports. If you still see issues at factory default settings, call support and open a case or return the switch to the reseller for replacement.

1130AG POE problem

1130AG AP, connected with Cat6 cable to Nortel 460-24T-PWR switch.
Switch is configured to supply up to 16W power to each port. I've tried 1130 in several ports and switch displays that it is delivering 4.5W to unit in any port I try.
1130 web admin page says that inline power source insufficient to enable radios. Documentation says that AP needs to draw 12.5W.
Both units are the default configs for POE, except I disabled POE on switch ports that don't need to use it.
Both sets of documentation claim that no other config is necessary. Supposedly, I should be able to connect it and it works, yet... it doesn't.
Anyone have this kind of setup that can tell me what needs changed?
TIA
Rick

IOS is version 12.3(8)JA
The only option in the IOS command is:
power inline negotiation [injector | prestandard] source
I've tried a couple of different cables, Cat5e and Cat6.
On the web admin page, there are two options for the power source - Negotiation or Pre-Standard Compatibility. When I set it to Negotiation, the display says "NOT YET DETECTED" although the switch still shows the unit drawing 4.5W of power. Setting to Pre-Standard Compatibility displays "LOW_POWER_CLASSIC_NO_INJECTOR_CONFIGURED" with the same power consumption on the switch.

3560 POE problem

We are using 3560 POE switches to power Symbol AP's. All the documentation I've read says the 3560 can power up to 24 AP's. We are only able to plug in 7 to 8 AP's before some start dropping out. Is there any other possible cause for this other than lack of power?

if you do a "show power inline" it should give you info like this

PoE problem with 3560-48 port

I am trying to power a door entry system which is 802.3af compliant (clas 3) from a 48 port 3560. It works on a 24 port version and on an HP switch but it will not work with the 48 port variant. The error log says "power Imax error". Looking at the documentation, although the switch cannot support all 48 ports at the full 15.4W, it should be able to intelligently manage power delivery to support up to 24 devices (I only need it to support 1), but this is not happening. Does anyone have any thoughts on this problem?
Thank you.

The cause of this Message is output in the following condition.
1. Either IEEE 802.3af power device or Cisco power device is detected.
2. Power is given to the device, but link is not up with (5 or 10 seconds), and power thenwill be removed and this error message is generated.
These features have been added to Cisco IOS Release 12.1(19)EA1c .

POE on Aironet 1130ag failes

Hi, I am trying to enable POE on our three new Aironet 1130ag but they fail to get the power from 6500 switches which have WS-X6348 modules and WS-F6K-VPWR sub modules. I disabled power injector and tried power negotiation and pre-standard compatibility without any success. Thanks.

Hi Reza,
I think you have already figured out the problem here :) This module - WS-F6K-VPWR only supplies 7W of PoE power and the 1130 requires 802.3af 15W PoE;
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Config_Notes/78_10826.html#wp31976
We had this happen to us recently due to a PoE problem. The 1130 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.

Have a look at this good Q&A;
Q. As with the 1200 Series AP, can a 1130/1240 AP work with 7 watts of power to it from a pre-standard POE with 802.11g radio alone disabled?
A. No, the power consumption on the AP1240 breaks down like this:
5 GHz only radio 11.56 watts
2.4 GHz only radio 12.96 watts
Both radios on 15.0 watts
The power consumption on the AP1130 breaks down like this:
5 GHz only radio 9.750 watts
2.4 GHz only radio 9.910 watts
Both radios on 12.20 watts
In either case, you can see that, for the AP to operate with a single radio, it requires more than 7 watts of power.

POE from 3524PWR Switch for 1130AG AP?

We have a bunch of 1130AG LWAPP access points that we are installing in various locations. Those locations with newer 802.3af switches such as the 3750's and 3560's power the AP's without issue. However we have mixed results plugging them in to older Cisco POE only 3524PWR Switches.
For the most part if we plug the 1130AG's into the 3524PWR's with short patch cords they power the radios up. However, if we connect them to a longer network line (80 to 100 feet) they disable the radios and WCS alarms tell me that the switch could not supply enough power for the radios.
The Quick Start Guide (page 14) shows the 1130AG supporting both Cisco POE and 802.3af power. Is there any way to get these to reliable power up on 3524PWR switches or do I need to use power cords or power injectors?

Migrating to 1250's

We are thinking of migrating to 1250's to start preparing for 802.11n.
My questions are can you have a mixed environment with 1130's, 1231's, 1242's and 1250's. If so, are there any problems with roaming between different AP's? or Power requirements We have for the most part WS-C3750-48PS-S, WS-C3750G-48PS-S and 6500's
WS-X6148A-GE-45AF cards in the access closets.
Right now we have Cisco 7921 phones and Vocera badges on "B/G", wireless laptop carts on "A".
I am not concerned to much with increasing speed at this point I am more concerned with having a stable environment until we complete the migration.

Hi Laura,
Yes, it's most cetainly a "PoE" problem;
Powering the Aironet 1250 Series Access Point with 802.3af Power over Ethernet
The Aironet 1250 Series Access Point with one RM1252 radio module installed requires 12.95W, which is within the 802.3af Power over Ethernet (PoE) standard. Any Cisco switch supporting 802.3af may be used to power the Aironet 1250 Series Access Point with one RM1252 radio module installed. This is ideal for businesses that chose to only deploy on a single frequency (2.4 GHz or 5 GHz). A single radio provides optimum performance with approximately 300 Mbps maximum PHY data rate. Customers who deploy dual-band, 802.11n radios and power the 1250 Series using standard 802.3af will have more reliable and predictable coverage than that provided by traditional 802.11a/g networks; however, operation will be limited to a single transmitter per radio with maximum PHY data rates of 150 Mbps instead of 300 Mbps per radio. Customers with a significant investment in 802.11 a/b/g client devices that have low-to-medium bandwidth needs but high-reliability requirements will benefit the most from this type of deployment scenario.
Powering the Aironet 1250 Series Access Point with Cisco Enhanced PoE
Cisco Enhanced PoE was designed for customers who want to install new PoE-enabled technologies that require greater than 15.4W per port to function at full capability, such as wireless technology based on the IEEE 802.11n standard. Cisco Enhanced PoE provides the full power requirements for dual-radio modules and eliminates the need to run an additional cabling drop or insert a separate power injector. Support for Enhanced PoE is currently available on a variety of Cisco CatalystÂ® switching platforms. For more information on Enhanced PoE, visit
http://www.cisco.com/en/US/prod/switches/epoe.html.
What are you using for the 1252's?? If you are using an "E" Series 3750 this is a very good thread;

2960s IOS Upgrade Issue

Hi
I have a issue when i try to upgrade the IOS of WS-C2960S-48TS-L, the curretn version is 12.2(58)SE2 , the verison im trying to upgrate to is 15.2.SE6.
I do the "archive tar /xtract tftp" command to extract all the files to the flash, then i do the "boot system flash:" command to change to the new but when i reboot the switch it loads the new ios then loads the old ios and boot using the old ios, how can i change to ignore the old ios ?

Here i am again...and with new weird news.
I've made new tests and analisys on my six WS-2960S-48LPS-L.
Cables are ok (said by TDR).
Five on six no way to upgrade, from CLI, upper 15.0.1-SE. This is the newest working IOS i found, tested:
c2960s-universalk9-mz.150-2.EX
c2960s-universalk9-mz.150-2.SE6
c2960s-universalk9-mz.150-2.SE6 <-- suggested by Cisco
c2960s-universalk9-mz.150-2.SE7
c2960s-universalk9-mz.152-2a.E1
no way to boot, always the same error i've already posted.
Tried to format the rom also, always same things.
Anyway with 15.0.1-SE that should have fixed the poe problems, poe doesnt work...So i guess it's a hardware problem. Well ...5/6... i must say i have really bad luck...
But now, give me your attention please.....
One of them works, every port do its job with my voip cisco 7912 phones, with an old IOS also (12.2.58-SE2). So, i checked if it is a 2960S-48LPS-L for sure, serial number on case is the same i have on the package. It says it's a LPS-L. So, from CLI, i tried a show version....look at this:

A problem with PoE devices in the Topology view (LMS 3.1)

Hello,
the customer has a problem with PoE devices in the Topology View. :-( He doesn't see the 2960 PoE devices with the PoE filter enabled in the topology view:-( He uses LMS 3.1 on Windows.
In the NetPro discussion I found that the list of PoE devices is in the following file:
POECapableDeviceTypes.properties
but I cann't to find thid file in the campus directory. In the campus folder are following folders: bin, etc, lib and www.

WAP4410N PoE (and other) Problems

Hi!
I own two WAP4410N-E V02 Access Points and I am (too) experiencing loads of problems even after upgrading both to the BETA Software Version 2.0.5.2
As most other users keep reporting, the router, for no apparent reason, will stop allowing connections after a given amount of time. The maximum I got my AP to stay "working" was for almost 19.5 hours!!! Several of £9.99 Netgear DG384G have stayed connected for YEARS without a SINGLE failure!!!
The MOST annoying problem I have is that my WAP4410N-E V02 Access Point is NOT working with PoE and I am having the exact same problem as described on here: https://supportforums.cisco.com/thread/2122117 and my PoE is NOT a "green" PoE EEE (Energy-efficiet Ethernet) 802.3az PoE, just in case Cisco support try to blame the PoE!
And before you ask, my PoE Switch is fully IEEE 802.3af (Power over Ethernet) compatible and delivers up to 12.5 Watts per port where the WAP4410N-E V02 has a Max power draw of 10.1W....
1) With cable connected in Wireless AP connect other end of cable to PoE switch
2) POE indicated lights up on Wireless AP, followed by Yellow (right hand-side) LED on switch port and POWER lights up on wireless AP
3) Green (left hand-side) LED on switch port blinks together with ETHERNET light on Wireless AP
4) POWER on Wireless AP blinks followed by ETHERNET on Wireless AP
5) WIRELESS on Wireless AP lights up
6) Suddenly all LEDs on Wireless switch off and POE dims to off followed by LEDs on swtich port
7) the above will start all over again!!!
The same PoE switch successfuly delivers PoE to other PoE devices including one device with higher demands than the Cisco AP!
The SAME problem happens even if I disconnect all other devices and the PoE switch has up to 38.5 Watts available!!!
Also to point out that after a factory reset the AP gets an IP address of 192.168.1.245, but NO other network info via DHCP so the only way to configure it is to directly connect it to a PC! This is just unacceptable!
I am deeply unhappy with this product and the amounts of hours I have spent configuring it, testing it, re-booting it, upgrading it etc etc
I have never had a single problem like this with any of my netgear products and cisco supposed to be better and it is more expensive!
So why are we paying the extra money for? The name? Because is not for the quality for sure!!!!
I will NEVER EVER not only buy another single Cisco product, but as an IT Consultant, I will NEVER, EVER sugest CISCO for ANYHTING, except if Cisco admits that this product was a total failure and agrees to replace it straight away with another (hopefully more tested) product!
In here I can see nothing but problems (and exaclty the same problems may I add) with everyone! And all Cisco is trying to do is blame others like "it is the fault of the "PoE" switch, "have you checked this" or "have you checked that"
Come on Cisco! Admit that the product was a failure and agree to replace it for eveyone that was unluky enough to buy it! At the end of the day, most of us are IT specialists that have better things to spend their billable hours on than trying to resolve problems on a product that was a total failure!
If Cisco support wants me to spend more hours to try silly suggestions, usless firmware and try to blame other equipment that works well with ALL OTHER probucts connected to it EXCEPT the WAP4410N, I have no problem with that, but please give me your billing address so I can charge you my wasted hours on testing your product directly. I have no problem with that.
I will exept nothing else than replacement with a better product with similar feautures! Not more waiting for a year at a time for firmware updates that do NOTHING!

Hello ry:
See my suggestion above (archive and install). I would not spend anymore time with arcane UNIX commands - they are not, IMHO, going to fix anuything. An archive and install will install a fresh OS X while, at the samne time, preserving files, programs, and settings. You will, of course, need to run software update after the A&I. It is always good practice to back up before any software update.
