IBM RS/6000 SP - Manual (Page 42)

Refer to notes at beginning of “SP Switch function (MAP 0620)” on page 1-17 for more information
on cable connections and logical-to-physical frame translations.
c. Be aware that for logical frames consisting of two physical frames, all out.top even-numbered
nodes represent nodes physically located in the expansion frame (F/C 1010) but at the next lower
slot number. For example, L01-N04 (logical frame 1, node 4) could be physically located at
E02-N03 (physical frame 2, slot 3).

v “On board connections...” Go to “Step 0620-041” on page 1-35 to replace the
switch assembly.
2
(2 of 5)
v “Primary node connection...”
v “Node connections...” on same switch
as primary node
v If this is a standard node, go to “Step 0620-005” to
check “primary” or “secondary” processor node
connection.
v If this is a dependent node (connection to router), go
to
″ Dependent node (MAP 0630) ″ in RS/6000 SP:
System Service Guide .

v “Wrapped ports”
v “frame # to frame #”
v “switch # to switch #”
v “Switch connections...”
Go to “Step 0620-021” on page 1-29 to check the
wrapped port or external switch connection.

v “Node connections...” not on same
switch as primary node. v If this is a standard node, go to “Step 0620-005” to
check “secondary” processor node connection.
v If this is a dependent node (connection to router), go
to
″ Dependent node (MAP 0630) ″ in RS/6000 SP:

(5 of 5)
v All problems in
/var/adm/SPlogs/css/out.top file have
been addressed. Go to “Step 0620-043” on page 1-36.
Step 0620-005
The /var/adm/SPlogs/css/out.top file indicates a problem with a “Primary node” or “Secondary node”
connection.
1. Open frame rear cover and check the cable connection from the indicated SP Switch jack to the
processor node.
2. Is there a cable connected to the indicated jack on the SP Switch?
v If yes, go to “Step 0620-008” on page 1-23.
v If no, go to “Step 0620-006”.
Step 0620-006
No cable connected at the indicated jack on the SP Switch (refer to the tables in “Switch data cables” on
page 2-13).
1. Should there be a cable connecting the indicated jack to a processor node?
v If yes:
a. Connect a switch data cable from this jack to the proper processor node.
b. Go to “Step 0620-043” on page 1-36.
v If no, go to “Step 0620-007”.
Step 0620-007
A switch cable is not required on the indicated jack.
