Table 3 Exerciser card status LEDs
LED Name/Label Description
Status LEDs on the board
16 status LEDs in upper left corner of the
board Displays the status of the lanes (x1-x16) in the link.
All these LEDs are off if the link is not up.
If the link is up, then the LEDs are on for only those lanes that are
participating in the link.
POK When this LED is ON, it indicates that the FPGA power supplies are
operating.
This is displayed in the upper right corner of the board.
UPOK When this LED is ON, it indicates that the Power supplies for the
microprocessor system and USB are operating.
This is displayed in the upper right corner of the board.
HB This LED represents the Heartbeat. It blinks at about 1 second rate to
indicate that the microprocessor is operating.
This is displayed in the upper right corner of the board.
DONE When this LED is on, it indicates that FPGA has been programmed
successfully.
This is displayed in the upper right corner of the board.
PE3.3 When this LED is on, it indicates that the +3.3V PCI Express power
supply from the bottom (SYS) connector is up.
This is displayed in the upper right corner of the board.
3.3VA When this LED is on, it indicates that the +3.3V Aux PCI Express power
supply from the bottom (SYS) connector is up.
This is displayed in the upper right corner of the board.
PE12V When this LED is on, it indicates that the +12V PCI Express power
supply from the bottom (SYS) connector is up.
This is displayed in the upper right corner of the board.
Status LEDs on front bracket
No light There is no link up between the Exerciser card and DUT.
Green There is a link up at the Gen3 speed (8.0 GT/s).
Fast Blinking light There is a link up at the Gen2 speed (5.0 GT/s).
Slow Blinking light There is a link up at the Gen1 speed (2.5 GT/s).
Red LED The red LED on the front bracket will be on until the FPGA receives a
valid configuration.
