PowerEdge System Components

Slotted System Boards

The PowerEdge 4400, 6400, and 6450 are all 32-bit servers using Slot 2 Intel Pentium III Xeon processors.

The PowerEdge 6450 and 6400 use essentially the same system board. The PowerEdge 4400 system board is similar to that of the PowerEdge 6400; the main difference between the two is that the PowerEdge 4400 supports a maximum of two processors, while the PowerEdge 6400 supports up to four processors.

• Memory 1 and Memory 2 connectors are for the separate memory riser card. The memory riser card allows support for greater amounts of RAM than would physically fit on the system board.

• Battery is the CMOS battery that allows the system to preserve BIOS settings when powered off.

• SVR MGT provides a system management interface to a Dell Remote Assistant Card (DRAC). DRACs are discussed later in this course.

• INTRUS 2 is a connector for the chassis intrusion switches that notify the system when the chassis has been opened. INTRUS 2 is unused in the PowerEdge 6400.

• POWER 1,2,3 are all power connectors for the system board. On the PowerEdge 6400, power is supplied to the system board by a power supply paralleling backplane (PSPB).

• Fans are fan connectors that provide power and monitoring for the system fans.

• SCSI 3 is a 50-pin SCSI connector that is rerouted through the ROSB4 IDE chipset. The connector is attached to the IDE CD-ROM drive used in the system.

• SCSI 1 and SCSI 2 are both 68-pin SCSI connectors connected to the 7899 dual-channel chipset.

• Floppy is a standard floppy drive connector.

• Backplane is a connector for the SCSI backplane.

• PROC1-4 are the slots for 1 to 4 Intel Xeon™ processors supported by the PowerEdge 6400.

• INTRUS 1 is a connector for the chassis intrusion switches that notify the system when the chassis has been opened.

• PCI LED PNL connects the PCI slot indicators to the system board.

• PCI 1 supports only 32-bit PCI cards (evidenced by the shorter length of the slot as compared to the others on the system board). The PCI 1 slot is also the only slot that has a system management bus connector adjacent to it to allow support for Dell Remote Management PCI cards.

• PCI Slots 2 - 5 support 64-bit or 32-bit PCI cards (evidenced by the physically longer slot than slot 1), but only support 33-MHz PCI cards.

• PCI 6 and 7 (denoted by the green color of the slots) support only 64-bit 66-MHz PCI cards.
