Appendix C Status Indicator LEDs C-5
C.2 Internal Status Indicator LEDs
The Sun Fire X4100 and Sun Fire X4200 servers have internal status indicator LEDs
for the fan modules, the DIMM slots, the CPUs, and the GRASP board.
FIGURE C-3
shows the locations of the internal LEDs. TABLE C-3 describes the LED behavior.
Note – To see the CPU LEDs, the GRASP board LED, or the LEDs in the ejector
levers of the DIMM slots, you must put the server in standby power mode (shut
down with the front panel Power button, but do not disconnect the AC power
cords).
