Perform a PCG Swap Test
Purpose To verify PCG failure by performing a PCG swap test.
CAUTION: Before performing a swap test, always check for bent pins in the
midplane and check the PCG for stuck pins in the connector. Pins stuck in
the component connector can damage other good slots during a swap test.
Action To perform a swap test on a PCG:
1. Have an antistatic mat ready.
2. Attach an electrostatic discharge (ESD) strap to your bare wrist, and connect the
strap to one of the two ESD points on the chassis.
3. Remove the rear component cover by loosening the screws on the corners of the cover
and pulling it straight out from the chassis.
4. Press the offline button on the faceplate of the PCG and hold it down until the Red
FAIL LED lights (about 3 seconds).
5. Loosen the thumbscrew on the right side of the PCG.
6. Grasp the thumbscrew and slide out the PCG.
7. Align the rear of the PCG with the guides inside the chassis.
8. Slide the PCG all the way into the card cage until it contacts the midplane.
9. Tighten the thumbscrew on the right side of the PCG faceplate.
10. Verify that the PCG is properly installed by looking at the LEDs on the PCG faceplate.
The green OK LED should light steadily.
