of the server. Each time you press the system ID button, the state of both the system ID LEDs changes. The
LEDs can be changed to on, blinking, or off.
3 DIMM error LEDs
When a DIMM error LED is lit, it indicates that the corresponding memory module has failed.
4 Fan error LEDs
When a fan error LED is lit, it indicates that the corresponding system fan is operating slowly or has failed.
5 FPGA error LED
The FPGA error LED helps you identify different FPGA errors.
Status Color
Description
On Green FPGA running image is test build image.
Blinking
Green
• Blinking (blinking slowly, about one flash per second): Power Fault happened.
• Blinking (blinking rapidly, about four flashes per second): FPGA does not assert
RSMRST_N.
Off None No Power Fault.
6 FPGA heart beat LED
The FPGA heart beat LED helps you identify different FPGA errors.
Status Color
Description
On or Off Green FPGA does not work.
Blinking
Green FPGA works normally.
7 FPGA power LED
The FPGA power LED helps you identify different FPGA errors.
Status Color Description
On Green The FPGA power is on.
Blinking Green
• Blinking (blinking slowly, about one flash per second): The FPGA power is off.
• Blinking (blinking rapidly, about four flashes per second): The FPGA permission
is delayed.
