RESTET to Factory

Use the reset button, while its powered on, hold it down for 10 seconds

the default IP is 192.168.1.251 default user/password is admin / admin

HOWEVER after a reset, dont have the switch plugged into a DHCP network, because DHCP is hardcoded as "ON" and that Ip will get over written. This isn't a problem, its just that you will have a frustrating time to make the IP work! So keep it stand alone until you either hardcode an IP or set the

You will then see on the screen "Enter Password: to Reset Settings."
When prompted for the admin password, enter the MAC address using the keypad (switch between numeric/alphanumeric as needed).

Here's what isn't mentioned a lot.

When you are entering in the alpha characters, you need to press the button on the phone to match the count of the characters.

So if your mac is 64167FE4, you would type in

64167 then on your phone press the "1->Aa" button and then press the 3 button three times to get an "F", because "F" is the 3rd alpha character on the 3 button
Before you enter in a numeric value, make sure you press the A-a1 button until you see it look like "1->Aa" which means you can type in number values.

Repeat this process until you get all the values typed in.
Confirm the reset when prompted.
The phone will reboot and restore factory settings, including resetting the admin password to 456.
