POE issue on cat 3550

[kmoshayedi]

01:12:51: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error, Interface Fa0/7

: Power given, but link is not up

I have connected a voip phone and ip camera getting the same error.. any idea ?

[kmoshayedi]

yes cisco IP phone or AP work fine.. .. I tested the camera and other Snom IP phone with a netgear POE switch and worked fine..guess we are going to dump our POS 3550 and get something that can do the job .. we have over 30 phone IP phones and I am not about to connect an injector in. .. POE ..

[kmoshayedi]

cat 3550 inline power POE = POS lol

[kmoshayedi]

according to the specs this unit is

IEEE 802.3af Power over Ethernet (PoE) Standard Compliant; 8 x  

[kmoshayedi]

SO the answe is NO .. EXPERTS

Q. Does the Catalyst 3550-24 PWR switch support the upcoming 802.3af inline power standard?

A. This switch will support the Cisco inline power implementation and 15.4W/port on all 24 ports. 802.3af

compliance cannot be claimed due to the current status of the proposed standard (draft form) and litigation involving

an alleged patent violation for the power disconnect portion of this standard. Full 802.3af compliance is dependent

on the outcome of this litigation. Vendors claiming current support for this standard should also inform their

customers of the risk associated with draft standard claims. The 802.3af standard is expected to be ratified Q2CY03.

Backward compatibility will ensure that previously sold Cisco IP phones and wireless access points will be compatible

with the new Catalyst 3550 inline power switch. Development of an 802.3af inline power Catalyst 3550 switch has

been difficult because of the uncertainty that has existed in the formation of the final IEEE standard.

Hi,

Will you please make sure you have "spanning-tree portfast" settings on the interaces. You can also try to extend the initial power shutdown delay to e.g. 90 seconds via the interface command "power inline delay shutdown 20 initial 90" or even further (to its maximum 300). To get more information about the PoE problem will you please set "debug ilpower controller" and do "shut/no shut" of the interface and post the output of the debug.

Thanks & Regards,

Antonin

set the timer to 20 /90

and here is the debug

is  802.3af support class 3 or 1

[amikat]

Hi,

Which Snom IP phone you are trying to connect? Majority of Snom models are 802.3af Power Class 1 or 2, but there are also models which use non-standard PoE solution.

Best regards,

Antonin

[kmoshayedi]

I have tried snom 360 and 320 ..  also a IP camera

[amikat]

Hi,

Both these IP Phones are of 802.3af Class 1, ie. requiring very low power. I try to find out if there are any specific requirements for these models, hope to came back soon.

Best regards,

Antonin

Hi,

I have tried to get detailed information about the 802.3af poe support for both the Cat3550-PWR switch and Snom IP Phones and failed. The information provided is rather ambiguous and I have not this setup in my lab. While your posted "sh power inline" output clearly indicates that Snom phone has been detected via Fa0/7 interface I also found the Cisco document saying that this switch does not support 802.3af at all:

http://www.cisco.com/warp/public/cc/pd/si/casi/ca6000/prodlit/psnap_br.pdf

The only other attempt I would try is to take the Snom Phone directly to the switch (provided you have an access) and connect it via short patchcord (to eliminate RF noice and possible cabling issues). BTW I hope you are using straight and not crossover cable.

I am planning to get the equipment and try locally in my lab, but it may take weeks or months to fulfil. I am sorry I cannot provide more help at the moment.

Best regards,

Antonin
