The process that worked for me 3 times straight.
Apc switched rack pdu factory reset.
Apc switched rack power distribution units pdus enable advanced user customizable power control and active monitoring.
If you forget the password to your apc rack pdu generation 2 starts with part number ap8xxx.
Resetting the network interface using the small reset button near the network jack has no effect on the electrical output of the rack pdu or rack ats.
I could not recall the login details for any of my three pdus.
You are not able to reset the unit to the factory settings on this model without gaining access via the serial console cable which is outlined in those instructions above.
I like to wipe the configuration from equipment prior to disposal.
I just had to reset an apc pdu and go thru this hassle.
The pdu defaults to dhcp bootp so 192 168 1 202 is from the previous user.
Press reset button with paper clip only 2 sec is necessary.
Then you can recover it by connecting to the pdu via the ser.
Fortunately i still had the serial cable required to get into the console.
Immediately press reset again only 1 2 seconds needed.
I have three apc pdu ap7900 and i m about to dispose of one of them.
Network port led s will start flashing.
Remote outlet level controls allow power on off functionality for power recycling to remotely reboot equipment and restrict unauthorized use of individual outlets.
Can you get the cable.
I also had my serial cable for my laptop.
