I have the same switch as you...
HP Series EO1010 (HP IP KVM Console (3x1x16))
Spares 286599-001
MPN: 520-274-016 Rev B
Serial Console and OSD passwords were lost...
Here is where I am at...
This switch is a re-branded Avocent KVM switch...
It is similar to the Dell 2162-DS KVM switch...
On a complete hunch... I downloaded a (Dell/Avocent) serial password override utility at the following link
http://dell.avocent.com/index.php?option=com_phocadownload&view=category&id=13:&download=28:2161&Itemid=49
Using the utility requires you to be connected to the console's management port (serial port).
The password override utility discovers the switch over the serial cable and returns a key that is used to override the serial console password. (By the way, you can't have Putty open at the same time you are trying to run the utility).
You need to provide the key to HP Support... They utilize the key and a product number to request a generated override password from Avocent. HP Support used the Spares number to come up with a product number.
When you get the override password from HP, you simply enter the password into the password override utility which will override the existing password and restart the console.
When the console restarts the serial console password protection will be removed allowing you to access the console's configuration menu.
From there... Menu option 5 is Restore Factory Defaults.
Unfortunately... that option did not reset the OSD password (on-screen display password, sometimes referred to as the OSCAR or console password).
I will re-post if I come up with a solution for the OSD password reset.
I can access the console switch via serial cable to manage basic configuration and access via network (TCP-IP) using the HP IP Console Viewer software (using ver 4.1)... just not sitting in the server room at the console itself (...yet).
