Cisco 7970 Brightness

[Anonymous]

Hi,

I have got a cisco 7970 running Sip, working ok in regards to calls via 3cx.
One problem the brightness is only half way. I have changed settings to max on the phone but still its in low power mode.
Its plugged in with a Cp-pwr-cube3, I was under the impression that POE will force it to run in half brightness mode. As i am using the power cube this has got me stumped.

Any ideas i've searched everywhere :cry:

This is a quote from this web page..."the reason a phone might power up in low power mode with the power injector is due to the phone's inability to distinguish midspan versus switch power when receiving power over Ethernet."
