WS-PWR-PANEL for AVAYA/NORTEL IP Phones

Hello all

Fisrt of all would like to thank you all for those who going thru this session:

We are running a call centre in india with AVAYA Ip Solutions. LAN/WAN side is completely engineerd with CISCO Devices whre we recently bought 10 Nos. for WS-PWR-PANEL to power up AVAYA/NORTEL IP Phones under the perspetion that this does support well.

We knew that AVAYA IP phone just need 48 V DC on pair 7&8 to power up over LAN. And this wouldnt support any Phone discovery algorithms or other varients from PSE while the voltage should be at a constant value of 48V.

We enabled WS-PWR-PANEL on blast mode, and we are able to see 48V between pairs 4&7 and 5 & 8 (both). When we interconnect this to an AVAYA Phone, the voltage suddently gets reduced to 9V DC. I hope this is becoz of IPPPs phoen discovery algorithms and associted CDP. IS there a way to disble CDP on PWR-PANEL and completely by pass phone discovery ?

Couple more info..

01. When we enable Blast mode , the "status "LED on WS-PWR-PANEL (along with all 48 ports in Green mode ) get on stationary "RED" . while on normal mode status mode glows as Green . Isint that Common ?

02. The port by which AVAYA IP phone connected shows on continouse binking, does that mean that it looks for phone discovery ? If yes, how do i disble that ?Any jumper settings insdie the box ?

Would appreciate if some one could help us in this reagrd with some quick views..

thanks

Re: WS-PWR-PANEL for AVAYA/NORTEL IP Phones

This power panel provides continous -48 VDC power. The power specifications of the power panel doesnt match with that of the Avaya phones. This problem has been detected earlier also. The avaya phones are not compatible with the Cisco power panel WS-PWR-PANEL.
