Chapter 4 Installing the Sun XVR-4000 Graphics Accelerator Hardware 27
The CPU indicator LEDs are located on the centerplane bar between slots B and C of
the system (
FIGURE 4-8
). On the centerplane bar, you will see icons to the left of the
LEDs that indicate that slot “D” is the topmost slot.

Sun XVR-4000 Graphics Accelerator Power LED Indicator
If there is a CPU module/Sun XVR-4000 graphics accelerator in any slot, ensure that
the corresponding green LED is lit. The green power LEDs of both the CPU and Sun
XVR-4000 graphics accelerator should always be in agreement, but the one on the
Sun XVR-4000 graphics accelerator is the most positive indicator that the board is in
fact powered up.
If any of the green power indicator LEDs on installed Sun XVR-4000 graphics
accelerators are not illuminated after attempting to power-up the system, power off
the system and apply thumb pressure to the center of any Sun XVR-4000 graphics
accelerator whose green LED failed to light. Note if any additional board travel is
experienced. If the board is not completed seated, push the board fully into place.
Then you may recheck the right-hand and left-hand captive screw torques with the
torque driver to ensure the screws are tightened to 8 in-lbs (0.90 meter-newtons).
