Hi ,
I'd like to know if there's anyone who can help or have seen this in the past.
8861 phones with expansion still disconnecting and cannot boot since the parameter " Power Negotiation " disabled on the phone.
if the parameter is enabled , the expansion cannot turn on .
all the phones impacted are running on the same switch
cucm 10.5.2
Firmware sip88xx.12-5-1SR2-2
many thanks for your help

Hi Mike,
i can see the AdminPwerMax and AdminConsumtipn is 15.4 W on the switch int :
Available:3537(w) Used:1006(w) Remaining:2531(w)

I do not know exactly what the requirements are for a Cisco 8861 + 1 expansion module . where I found that the expansion alone needs 5 w

Thank you very much,
we are using a WS-X45-SUP7 line-card wich support only RJ-45 PoE IEEE 802.3af and Cisco prestandard .
i am not sure that we can increase the max power with this type of line-card.
for the moment, a colleague is forcing the "AdminConsumption" directly on the int to 14.2 and it works but I doubt very much that it's not the best practice and i ignor the impact that this workaround can cause .
