Cell Board LEDs
There is one green power LED located next to each ejector on the cell board in the server that indicates the power is good. When the LED is illuminated green, power is being supplied to the cell board and it is unsafe to remove the cell board from the server.
72 Troubleshooting
There is one yellow attention LED located next to each ejector on the cell board in the server.
When the LED is flashing yellow, it is safe to remove the cell board from the server.
