Table1-8. Service Request Numbers (SRNs) for SP Switch2 adapters (continued)

Service Request

Number SRN

Source Failing Component Description Notes

Notes:

1. Ify=1in these SRNs, you must troubleshoot the SP Switch2 adapter software (SRN 765-x1xx) before you

follow procedures related to a hardware item.

2. x may be any digit.

Step 0620-012

An SRN was obtained and Table1-8 on page 1-24 was used to determine the list of possible failing

components.

1. From the list of possible failing components, use the following prioritized table (Table 1-9) to perform

service.

Table1-9. Switch Problem Priority Listing

Priority Failing Component Action

1

(1 of 6)

Software a. Have customer verify that the software is configured

and operating correctly for this processor

node/system.

b. If no problem is found, continue with next highest

priority item in the list for this SRN.

c. Otherwise, power off this processor node and continue

service at “Step 0620-013”.

2

(2 of 6)

Data cable a. Check to see if a switch cable is connected at switch

adapter of this processor node.

b. Reseat switch data cable at switch adapter of this

processor node.

c. Run advanced diagnostics on the device “cssX”

(where X=0 or 1) and its associated switch port.

d. If diagnostics fail with the previous SRN, replace

switch data cable.

e. Continue service at “Step 0620-014” on page 1-26.

3

(3 of 6)

SP Switch2 adapter a. Replacethe switch adapter card on this processor

node.

b. Reconnect all cables to the processor node.

c. Continue service at “Step 0620-014” on page 1-26.

4

(4 of 6)

System or I/O planar a. Run advanced diagnostics on the “Base System” or

I/O planar.If a problem is detected, use SRN to

service.

b. Replace the system or I/O planar on this processor

node. Make sure to reinstall all parts and cables.

c. Reconnect all cables to the processor node.

d. Continue service at “Step 0620-014” on page 1-26.

5

(5 of 6)

Wrap plug or

Terminator Checkthe wrap plug or terminator again to make sure

that it is not at fault.

6

(6 of 6)

All components replaced. Call next level of support.

Step 0620-013

An SRN listed in Table1-8 on page 1-24 indicated that you have a software problem and Priority 1 in

Table1-9 directed you to this step.
