Note: In a frame with processor nodes, entries for the switch will refer to “node17” or “slot17”. In a
multi-switch frame, switches will be listed as even slot addresses.
Notes:
1. SP Switch2 advanced diagnostics use the 8.75 meter data cable provided by the SPS feature bill of
material.
2. Advanced cable wrap tests will not run successfully for 10-, 15-, and 20-meter SPS data cables. If
these data cables are used, change the suspected cable.
