to fix problem.
Step 0620-011
The Power (green) LED is lit, indicating the processor node is powered on.
1. Run advanced diagnostics in service mode on device “cssX” (where X=0 or 1) on this processor node
and its associated switch port. Refer to:
v“Running diagnostics on a switch port” on page3-12.
v″Running diagnostics in a processor node″in
RS/6000 SP: System Service Guide
Notes:
a. Advanced cable wrap tests will not run successfully for 10-, 15-, and 20-meter SP Switch2 data
cables. If these data cables are used, swap or change the suspected cable.
b. Advanced “cssX” (where X=0 or 1) diagnostics will require a male and a female wrap plug to
perform the card wrap and cable wrap tests. When testing the SP Switch2 adapter, the cable
associated with the male and female wrap plugs included in the ship group must be used to
perform card diagnostics (refer to
RS/6000 SP: System Service Guide
).
c. If unable to run diagnostics, make certain the adapter is configured correctly.
d. If the adapter is configured correctly and diagnostics fail, replace the card.
2. Do you get a Service Request Number (SRN) from “cssX” (where X=0 or 1) diagnostics?
vIf yes:
a. An SRN was obtained from diagnostics.
b. Use the following SRN table (Table1-8) to continue service.
c. After using Table1-8, go to “Step 0620-012” on page 1-25.
vIf no:
a. The diagnostics did not detect a problem, therefore the problem is in switch assembly.
b. Go to “Step 0620-020” on page1-27.
