My grandstream 101 voip phone

I was using a Grandstream 101 voip phone when accidentally using a power supply having 9 volts DC. Its power is actually 5 volts. The internal program of the phone is working ok and could reset itself. The problem now, it could not anymore link with the D-LINK router which is connected to the internet. Upon examination of its board the maximum voltage of the capacitors were 16volts. There was no burn parts observed. What do you think is the problem. Other Grandstream model used with this router has no problem at all. Lixberto

Power supply polarity for Viking K-2000-DVA

The center pin of the power jack on the unit is negative (-) 12 volts DC. It is also common to all of the input common terminals. This is important when using a common power supply for other equipment such as 12 volt battery backed system for an alarm system.

My handy tone-486 box keeps flashing red every 3 seconds and I have no dial tone. My internet works and I have power and a working phone line to the box. Help.

Lifted this straight from the manual:

Button flashes every 4 seconds
(if SIP server is configured)
HT–486 fails to register

So basicly, that means your HandyTone 486 ATA fails to register with the SIP-server. That means you either have not recieved your IP-tele yet, or that your ISP have failed to register you.

A wrong pass word was entered and the devise was can i access the device again?

you would need to factory reset the adapter if you dial *** then 02 it will give you ip address now if you put the ip address into your main web browser it will pull up a configuration page for your handy tone you will see a tab on the left hand side that says reset click that and factory reset the device this should wipe out all current configurations on tht device

Have system for voip. Only can't hook up the

Try getting a router that has one in/4 out between modem n voip. Your voip unit should have an RJ45 connector to connect to router, not your computer. The USB connector might be to connect the voip to a different type of router, and will not be used. The 2 phone connectors are for two different phone lines that your voip provider can provide you with.

Password for 486

Remove the battery from the mother board.
Jumper the CMOS to discharge it. You may
want to check you Mother Board manual, to
see which jumper it is. Some require you to
turn the Mother Board BACK ON for two seconds. (It will NOT come up, just will
discharge the CMOS and the battery will NOT
be there to replace the energy, so everything
is GONE. You will know if you have done it right, when
you boot up again, the BIOS will NOT recognize the hard disk (need to set it up
again), the date will be wrong (set it up again also) and the floppy drive will not
be recognized (new setup). But then try your password. It should let
you right in then. Let me know if it works. Best Regards, PS Make sure you have the right mother
board jumpers to discharge the CMOS, YOU
CAN DO DAMAGE ALSO, if they are not the
right ones.
