U4305A Exerciser Card 1
Figure 2 U4305A/U4305B Exerciser Card components on front bracket
The hardware components displayed in the above figures of the U4305A/U4305B Exerciser card are
described:
•
Edge Connector : This component is used to connect the U4305A/U4305B card with a PCIe
Connector on the backplane board, or with a system.
• Status LEDs (on board) : This component has the LEDs to display the status information about the
participating lanes of the link and power status of board and exerciser card. 16 LEDs displaying
the lane status are in the upper left corner of the board and the rest of the 7 LEDs are in the upper
right corner of the board. The module number to which U4305A/U4305B is configured is also
displayed in the upper left corner.
To get a description of each LED on the board, refer to the topic “Exerciser Card Status LEDs in
this chapter.
• Status LEDs (on front bracket) :
The green LED represents the link speed status and has the following different states:
•
No light means there is no link up between the Exerciser card and DUT.
• Green light means there is a link up at the Gen3 speed (8.0 GT/s).
• Fast blinking light means there is a link up at the Gen2 speed (5.0 GT/s).
• Slow blinking light means there is a link up at the Gen1 speed (2.5 GT/s).
The red LED on the front bracket will be on until the FPGA receives a valid configuration.
