HP HSR 6600 Router Series - HP A6600_HSR6602-CMW520-R3103P04 Release Notes Release Notes

 If no backup configuration has been saved but it is still possible to access the device

management via some method while running the old code (e.g. Console, Telnet or SSH), then

you can redefine all the device management passwords as required.

 If after a downgrade it is impossible to login to the device via any method, then there are two

ways to recover the router:

 From the BOOT menu, set the new code to run again and reboot the device. Disable Telnet

authentication:

User-interface vty 0 4

Authentication mode none

Then save the configuration and downgrade the code again, login via Telnet and reset all

the passwords as required.

 From the BOOT menu. On boot-up, use Ctrl+B to enter the Boot menu and then force the

unit to use the factory default configuration (bypassing the user configuration). The unit will

then need to be fully reconfigured.
