Security Issues for Certain Firmware Revisions
Error Messages and Secure Environments

Error Messages and Secure Environments

If you cannot upgrade the firmware prior to using the security features, 

Keysight will help you to recover from error messages that may appear after 

executing the security functions. The error messages indicate that instrument 

system files have been erased. The following list shows some possible error 

messages:

—

256, File name not found; /SYS/LICENSE.TXT

—

617, Configuration Error; License file not found. Creating 

empty one.

—

A missing or damaged system file was encountered while 

trying to diagnose the system.

Even if these error messages appear, the security function has completely 

sanitized the instrument. If the instrument is located in a secure environment, it 

is safe to remove it. After removing it from the secure area, follow the process 

below to recover the lost system files.
