Redundant Hot-Swap System
Your redundant hot swap system features the following major components:
Single or dual high-performance Pentium Xeon processors in a 608 pin Intel Xeon
processor socket.
512 MB to 4 GB of ECC SDRAM (DDR333), using up to four DIMMs.
A high-performance synchronous system bus to interconnect the CPU and memory
subsystems with a bridge to expansion bus I/O.
On-board enhanced SATA 1.0 interface controller
Four integrated I/O expansion PCI slots (2 x 32bits/33MHz PCI; 2 x 64bits/66MHz
PCI-X)
Integrated CD-ROM and 1.44MB diskette
Six SCSI or four S-ATA hard disk expansion bays accessible from the front of the
chassis.
Four removable media expansion bays
High degree of hard disk drive fault tolerance and advanced disk array
management features through the use of RAID Technology if the optional RAID
controller is installed or using the embedded S-ATA host RAID controller.
Embedded PC-compatible support (serial, mouse, keyboard, diskette, USB, LAN,
and video).
Integrated onboard ATI RAGE XL Video Graphics Array (VGA) controller with 8
MB of video memory.
Optional SCSI or S-ATA controller. Refer to specifications in the guide
accompanying the controller board.
Integrated onboard Network Interface Controller (NIC), an Intel 82541 PCI LAN
controller for 10; 100 or 1000 Mbps Fast Ethernet networks with one RJ-45
Ethernet connectors.
On-board enhanced IDE interface controller (ATA100 × 2)
Two integrated universal serial bus (USB) ports.
Chassis that supports up to two power supply units. The additional power supply is
needed to provide redundant power (i.e., the system will continue to operate with a
single power supply failure).
Self-contained power supply units that are hot swappable and can be easily
installed or removed from the back of the chassis without turning the system power
off.
Key locked front bezel.
Easy access to all parts for service.
