1 Introduction

GigaAccel 180 is an accelerator board based on IBM’s PowerXCell 8i

processor. The board has 4GB of DDR2 SDRAM, two 1 Gigabit Ethernet Ports,

one x16 PCI Express interface, and it can run Linux. This makes it possible to

put the vastly superior floating-point calculation capabilities of PowerXCell 8i

on a standard workstation. Since this accelerator board does not have a hard

disk drive, it network boots by obtaining the boot image from the boot server

through a TCP/IP network.

3 Connection of GigaAccel 180

This section explains the instructions for connecting GigaAccel 180 onto

the host machine. The target host machine must have a x16 PCI Express

interface (2 slots), and an AUX 12V 6-pin power connector for PCI Express.

3.1 Preparations

Prepare the following cables which are included in the packaging.

ySerial cable

yEthernet crossover cable

If possible, please work by using "Static electricity prevention wristband (SANWA

SUPPLY TK-SE6)" etc. to prevent damage due to static electricity when connecting

GigaAccel 180.

3.2 Directions of connection

(1) Connect the 3-pin end of the serial cable to the board’ serial port. 9-pin side

is put out from an empty slot to the outside of the host machine.

Serial connector(3-pin)

* Connect the marked end to the outside

Serial connector(9-pin)

[Note] If the host machine has no serial port(9-pin side), please connect the serial cable

to the USB port by using USB-serial conversion cable.

(2) Open the computer case, confirm that an x16 PCI Express slot is available,

then remove that slot cover and the slot cover below it.

(3) Insert GigaAccel 180 into the empty x16 PCI Express slot.

x16 PCI Express slot

[Note] PCI-express connectors must be handled with care. If the connector is not

installed firmly on the slot, GigaAccel180 may not function correctly.

(4) Attach the PCI Express AUX 12V 6-pin power connector to GigaAccel 180.
