Recovering BIOS Data
Two system BIOS, primary and secondary, are used to realize the duplex configuration.
Normally, the system operates with the primary BIOS. If the primary BIOS data error occurs or the
device containing the system BIOS fails, the control is immediately transferred to the secondary
BIOS. Thus, the activation of the system is ensured.
At the shipment, the latest version of system BIOS is stored both in the primary and the secondary
BIOS. If you execute the system BIOS update, the secondary BIOS is updated, and the updated
BIOS becomes the primary BIOS. Thereafter, the system is activated from that primary BIOS.
System Cooling
The chassis includes a hot-swappable fan module with six fans for cooling the processor(s), hard
drives, and PCI cards. The fan system is located in the middle of the chassis to pull cooling air
through the chassis.
