SafeGuard CryptoServer x
What are the different runlevels of the CryptoServer?
Basically the CryptoServer can be (if the respective software is loaded) in four different modi, depending on which firmware is actually active:
1. Power down mode
The CryptoServer is in power down mode if no firmware is active (CryptoServer is shutdown). In power down mode the CryptoServer is not able to receive any command. A hardware reset has to be performed to get the CryptoServer active again.
2. Boot loader mode
The CryptoServer is in boot loader mode if the boot loader is active, i. e. the boot loader is powered up but the CryptoServer’s operating system (if loaded at all) has not yet been started.
3. Normal operational mode
The CryptoServer is said to be in normal operational mode if it is in operational mode and the firmware modules have been started from the FLASH directory (normal way of starting).
4. Failsafe operational mode
The CryptoServer is said to be in failsafe operational mode if it is in operational mode but the (back-up copies of the) operating system module SMOS and the base firmware modules have been started from the SYS directory. (So as long as the CryptoServer is in failsafe operational mode, no module from the FLASH directory is running).
