IBM RS/6000 SP manual Step, SP Switch function MAP

SP Switch function (MAP 0620)

1.Make sure a wrap plug is properly installed on the connector. Refer to Figure 1-2 on page 1-4for views of the switch wrap plugs.

2.Have customer check (and update if necessary) the switch configuration file appropriately before continuing:

v For code level 1.02 and higher, use the Etopology command.

3.Did you just correct a problem with a wrap plug or correct the switch configuration? v If yes, go to ªStep 0620-043º on page 1-36.

v If no, go to ªStep 0620-041º on page 1-35 to service or replace the switch assembly.

Step 0620-008

You have a switch cable connected to the indicated jack on the SP Switch.

1.Check cable connection at SP Switch and processor node.

2.Does the cable appear to be fully connected at the SP Switch and the processor node?

vIf yes, go to ªStep 0620-009º.

vIf no:

a.Fix the cable connection problem.

b.Go to ªStep 0620-043º on page 1-36.

Step 0620-009

The cable appears to be fully connected at both the SP Switch and at the processor node.

1.From the front of the RS/6000 SP frame or from the control workstation, check the Power (green) LED on the processor node to make sure it is lit.

2.Is the Power (green) LED lit, indicating the processor node is powered on?

vIf yes, go to ªStep 0620-011º.

vIf no, go to ªStep 0620-010º.

Step 0620-010

The processor must be powered on for the switch to recognize the port.

1.Power on this processor node, and check the Power (green) LED.

2.Does the Power (green) LED stay lit, indicating the processor node is powered on? v If yes, go to ªStep 0620-043º on page 1-36.

vIf no:

a.The processor node has a power problem.

b.Go to ″Processor node diagnostics and descriptions (MAP 0130)″ in RS/6000 SP: System Service Guide 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 ªcss0º on this processor node and its associated switch port.

v Refer to ″Running diagnostics in a processor node″ in RS/6000 SP: System Service Guide and ªRunning diagnostics on a switch portº on page 3-12.

Notes:

a.Advanced cable wrap tests will not run successfully for 15- and 20-meter SPS data cables. If 15- or 20-meter data cables are used, swap or change the suspected cable.

b.Advanced ªcss0º diagnostics will require a male and a female wrap plug to perform the card wrap and cable wrap tests. When testing the SPS adapter, cable part number 46H9699 will also be required to perform card diagnostics. This cable is part of the SPS feature bill of materials.

c.If unable to run diagnostics, reseat or replace the card.

2.Do you get a Service Request Number (SRN) from ªcss0º diagnostics?
