Introduction

Server Components

Chapter 1

Memory

• 12 memory DIMM slots

• 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB standard 184 pins 2.5 V DDR1, CL2, registered, ECC

• 133 MHz memory bus frequency, 266 MTransfers/s data, 8.5 Gb/s peak data bandwidth

• Minimum memory size of 1 GB with four 256 MB DIMMs

• Maximum memory size of 32 GB with eight 4 GB DIMMs

• Upgrades must be made by quads of DIMMs

• DIMMs loaded by quads enable interleaved mode & chip spare

PCI Riser

• Four independent PCI-X 133 MHz 64 bit, 3.3 V, 15 W slots. There is no 5 V card & hot plug support

NOTE Some 25 W cards are supported. See the following slot matrix (by server):

Internal Core I/O

• Dual channel SCSI U320 interface, two internal 68 pin connectors, one 68 pin external connector

• The three internal SCSI drive connectors are the 80 pin type and provide drive electrical hot-plug

capability

• One internal IDE connector for a slim-line optical device (CD and DVD)

• No floppy connector

External Core I/O

• One SCSI U320 68 pin connector

• Two 10/100/1000Base-T ethernet LAN connectors for twisted pair cable

• Four USB 2.0 ports

• Two general purpose 9 pin serial ports, 16550 compatible

Power Supply Unit

• 600 W output power

• The power supply is split in a front-end block (the actual power supply case) that converts the line voltage

into a high DC voltage. Back-end voltage regulation modules (on the system board) step down the front

end DC voltage to the required voltages

• Redundant and hot-pluggable power supplies (front-end block only)
