Card LEDs
`~êÇ=ibaë
On the front edge of all cards, two LEDs indicate the card’s FPGA and power status.
Figure 2-15. 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.”
