Use IE to look at http://www.hp.com/networking/configurator/.

Click the Product Selectors | Switches, and you can put in the relevant details and have it help select a model or models for you.

Thank You "Richard"

This site is also useful to me, but i want technical support my problem is crossover cable is support to cisco ip phone 7960g but "Stright Through Cable is not Getting Power"

 And my swtich model is : HP ProCurve Switch 2610-24-PWR (J9087A)

Unrucky! That is why you should stick to standards-based products!

The Cisco 7960G phone requires pre-standard power (ie not POE/802.3af)

You may be able to get the 2610 to provide "pre-standard" power, but I haven't tried. The ProVision based ProCurve switches have "power-over-ethernet pre-std-detect" that you could try.

 i try this command also power on pre-standard detection but my ip phone is not getting power still same problem.

Hi

So command "power pre-std-detect" doesn't resolve the issue for you? Do you have this problem with all the switch ports? Are you running current SW for your switch? Are you running current FW on the phones?

I'm not too familiar with these phones, but I'm not familiar with any issues like this between them and the 2610 switch. Have you tried manually setting the port mode to MDI or MDIX?

If you have a current FW / SW versions and you have tried manual setting, contact support.

 hi arimo,

i try MDI and MDIX manually its not get power in straight through cable but crossover cable is working in MDI mode. and i upgrade FW also no responses in my switch. iam no t upgrade FW in Cisco Ip phone 7960g.

Hi

A colleague stumbled on the solution:

http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02596877&lang=en&cc=us&taskId=&prodSeriesId=3751584&prodTypeId=12883

QUESTION: What pre-standard PoE devices are supported?

ANSWER:

• Cisco 7902G, 7905G, 7912G, 7940G, 7960G IP Phones
• Cisco Aironet 350, 1100, 1200, 1230AG Access Points
• Mitel 5220 (non-dual mode) IP Phone

NOTE: Cisco pre-802.3af standard phones require the use of a cross-over cable from this switch to their device. These devices are dependent on the polarity of the DC voltage (a violation of the 802.3af standard).

So because of the phone design you have no other option but cross-over cables.

hi arimo,

if i upgrade my cisco  phone 7960g FW then possibility to rectify the following problem.

Hi again

Nope, I don't think that's going to help.

I'm not familiar with these phones, but generally power supply wiring is a hardware design. That can't be changed through firmware.

Hi

I have J8164A (2626) deployed and is not powering up my 7912 cisco phones but wokring with latest models. I have found the command

power-over-ethernet pre-std-detect  as a solution. Now i have replaced the switch by J8692A 3500yl and able to configure the above command and phones are taking power. Please anyone help out me on why the same command is not available on 2626. Also let me know which is the latest verison of FW for the 2626 switch.
