Abstract
A blade server module in an information handling system may have secure environment and authorized removal modes in non-volatile memory. If the secure environment mode is set in the blade server module, then the authorized removal mode is read to determine whether it also is set. If both of these modes are set then authentication keys of the inserted blade server module and blade server chassis are verified as being properly associated. If the authorized removal mode is not set when the blade server module is inserted into a server chassis or authentication keys are not verified as being properly associated then the blade server module power-up sequence is disabled. The authentication keys may be administrator/user defined. The secure environment and authorized removal modes may be set and cleared by the administrator/user.
