Introduction Server Components 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): http://www.docs.hp.com/en/SSM1-EL/slotmatrix.htm For more information regarding specific I/O cards, see: http://www.docs.hp.com/en/netcom.html 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) 18 Chapter 1
