Step 0595-001

Perspectives indicates that a power problem exists and the yellow LED on the SP Switch2 supervisor is On and it is not flashing.

1.Perform the ªSP Switch2 supervisor self-testº on page 3-6.

v While the test is running, compare the LED conditions on the supervisor with those listed in ªSelf-test Conditionsº on page 3-7.

2.Did the supervisor pass the self-test? v If yes, go to ªStep 0595-002º.

v If no, go to ªStep 0595-003º.

Step 0595-002

The supervisor passed the self-test. This indicates that the self-test may have reset the supervisor processor and you need to determine if the problem has been cleared.

1.Refresh Perspectives.

2.Power on the switch.

3.Does Perspectives indicate that the original problem is still present or that a new problem is occurring?

vIf yes, return to the Start MAP (0100) in the RS/6000 SP: System Service Guide.

vIf no, go to the End of call procedures (MAP 0650) in the RS/6000 SP: System Service Guide.

Step 0595-003

The SP Switch2 supervisor failed the self-test therefore, you need to analyze the LED conditions you observed during the self-test.

1. Did the green and yellow supervisor LEDs light?

vIf yes, go to ªStep 0595-005º.

vIf no, go to ªStep 0595-004º.

Step 0595-004

Both green and yellow supervisor LEDs did not light during the self-test.

1.Check the supervisor LEDs on the nodes connected to the same supervisor cable as the switch.

2.Are any other supervisor LEDs lit? v If yes:

a.Replace the switch supervisor.

b.Go to ªStep 0595-008º on page 1-8.

vIf no, go to the Start MAP (0100) in the RS/6000 SP: System Service Guide and troubleshoot the supervisory bus system.

Step 0595-005

The switch supervisor failed the self-test. However, during the self-test the green and yellow LEDs on the supervisor did light.

1.Did the yellow LED flash the wrong address or was it on steady after the self-test completed? v If the yellow LED flashed the wrong address, go to ªStep 0595-006º on page 1-8.

v If the yellow LED was on steady after the self-test, go to ªStep 0595-007º on page 1-8.
