ScreenOS provide two methods to reset a device to the factory default settings.<\/p>\n
Hard reset (Pinhole reset)
\nSoft reset (Console login)<\/p>\n
The pinhole reset method can be difficult to achieve if you do not have a console session going to see the prompts.\u00a0 As the process requires two times holding in the reset button at the correct intervals.\u00a0 This can be done by observing the lights but can be tricky to get the timing right.<\/p>\n
The console login with the serial number is quite easy if the cable is available and the unit accessible.<\/p>\n
An important caveat to using these methods is that both of these reset functions can be disabled by a configuration statement.\u00a0 And if the current configuration does disable the feature you cannot perform that type of reset.\u00a0 Check for this in the configuration.<\/p>\n
set admin hw-reset<\/p>\n
If you do not have the root login to the device but have another login, you have other options.<\/p>\n
Reset the password of the root user if your account has permission, download the configuration and replace the root login statements with these default ones that will set the user\/password to netscreen\/netscreen. Then load and replace this configuration into the device.<\/p>\n
set admin name “netscreen”
\nset admin password “nKVUM2rwMUzPcrkG5sWIHdCtqkAibn”<\/p><\/blockquote>\nReferences:<\/h2>\n
