Introduction
Accessible drives
A 3,5-inch floppy disk drive (1.44 MB) and three locations for the installation of
accessible drives (CD-ROM, DVD-ROM, CD burner or tape drive) are available.
The accessible drives cannot be replaced during operation.
Alternatively, two of these locations can be used to install the optional HDD
extension box. As a result these locations are then no longer available for acces-
sible drives.
Power supply
In its basic configuration level the server has a fixed power supply unit or on/two
hot-plug power supply unit(s) that adjusts automatically to any power voltage in
the range from 100 - 127 V and/or 200 - 240 V. As an option, the standard power
supply can be upgraded to a redundant power supply (two hot-plug power
supply units). If one power supply unit fails, the second power supply unit of the
redundant configuration ensures unimpaired continued operation. The defective
power supply unit can be replaced during operation (hot-plug).
High level of availability and reliability
When memory data are accessed, 1-bit errors in the main memory are recog-
nized and automatically corrected with the ECC (Error Correcting Code)
method.
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
the case of an error and automatically ”hides“ the defective system components.
The PDA (Prefailure Detection and Analyzing) technology from Fujitsu Siemens
Computers analyzes and monitors all components important for system
reliability.
Optional add-in RAID controllers support RAID Levels 5 and 50 and increase
system availability and reliability.
The hot-swapable HDD modules provide additional protection.
