Slow printing


Either the power supply in not generating proper 48 Volts or the controller board is not detecting a 48V output from the power supply.
First of all make ensure that power supply and controller board are correctly connected (check for loose contacts). Unfortunately there's not much you can do. The problem is either in the power supply or the controller board. There is a special tool for testing the power supply and deciding whether to change the power supply or the controller. From what i've seen in the field, most of the times its the power supply that fails. I can send you the power supply test procedure. If youre interested letme know your email.

Not working cisco 7962


For starters, have you obtained a Cisco Phone power supply for your 7962G? These phones require either a local 48V AC Adapter, or Power Over Ethernet, in order to power up.

7945g can't use power supply of 7940


You'll need to buy a another power supply unless you have power over Ethernet. The power supply for 7940G/7960G is CP-PWR-CUBE and for 7941G/7945G you'll need a CP-PWR-CUBE-3. Yes, I know, I just got one of those and it's a pain to configure it, but I got it working... ;-)

P.S. If you haven't notice, you will be dealing with a whole different thing, the configuration/settings will ALL (except for the dialplan file) different from the 7940G... Good Luck ;-)

I need a 5kW DC generator with -48v output.


I have 5kW generators that produce -48V DC. The problem is that unless your generator is designed to produce -48V DC it would be difficult to retrofit an existing AC voltage output with a DC output.

Connecting phantom microphones without result


if you have a volt meter check the supply is working correctly
48v dc phantom power should be found between these pins on any xlr mic cable.

pin 1 and pin 2
also between pin1 and pin 3

make sure you have amps turned down before checking/switching 48v phantom power

as if all is up and running it can cause big noise in the speakers.

let me know how it goes
