CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION The Cyclone Microsystems 2708 PCI Express Gen2 Expansion System is a PCI Express (PCIe) expansion system that allows the user to add up to eight PCI Express add-in-cards. Most PCs contain few PCI Express slots making them poorly suited for embedded systems requiring many different I/O boards and co-processor resources. The 2708 PCI Express Expansion System permits system developers to use powerful and cost-effective PCs as a foundation for a robust embedded system.

CHAPTER 2 THEORY OF OPERATION 2.1 THEORY OF OPERATION The basic PCI Express link consists of dual unidirectional differential links, implemented as a transmit pair and a receive pair. The signaling rate for PCI Express Gen1 is 2.5 Gigabits/second/Lane/direction and Gen2 is 5.0 Gigabits/second/Lane/direction. A link supports at least one lane. The PCIe-425 is installed in a x8, Gen1 or Gen2 host slot. The PCI Express link from the PCIe-425 over the cable to the PCIe-451 is an eight lane (x8) Gen2 link.
CHAPTER 3 EXPANSION CHASSIS 3.1 600-2708 CHASSIS The PCIe-451 Expansion Backplane is installed into a seven slot rack mountable chassis. The chassis provides access to seven of the eight PCI Express slots. All slots can accommodate standard height and full length PCI Express add-in cards. The chassis also contains three drive bays that may be used to install peripheral devices for specific applications.

CHAPTER 4 SYSTEM OPERATION 4.1 SYSTEM POWER UP The host PC with the PCIe-425 installed controls power-up for the entire system. The PCI Express cable should be connected between the PCIe-425 and the PCIe-451 and the 600-2708 power cord should be connected to the chassis and plugged into a power socket. There is a power button on the front of the 600-2708 Expansion Chassis, however, it is not connected and serves no practical purpose in this application.
SYSTEM OPERATION The top (or right) LED on the panel is "Expansion System Signal Detect". The LED is on when the PCIe-425 detects a signal on Lanes 0-3 of the PCIe cable. The LED ON indicates normal operation. If the LED is not on, there is something wrong with the cable or the expansion system is not operating properly. 4.3.
