Card LEDs
`~êÇ=ibaë
On the front edge of all cards, two LEDs indicate the card’s power status, and the status of
all FPGAs on the card.
Figure 2-13.
Card front edge LEDs
Following are descriptions of the two LEDs:
1)
Card Power LED
The
Card Power LED
indicates power status for the card.
~
Green
= card power is OK.
~
Red
= power is bad (or has failed) on the card.
~
Off
= the chassis is turned off or power has failed.
2) Loaded
LED
The
Loaded LED
indicates the status of all FPGAs on the card.
~
Green
= all FPGAs are loaded successfully.
~
Red
= an FPGA is bad, or software has not properly loaded.
~
Off
= the chassis is turned off or power has failed.
Note
An
FPGA
(field-programmable gate array) is a semiconductor
device that can be configured by the engineer after
manufacturing — hence the name "field-programmable.”
