Step 0620-019
Since the diagnostics did not return an SRN, no problem was detected.
1. Have you just reseated, repaired, or replaced a component?
v
If yes, go to “Step 0620-043” on page 1-36 to verify fix.
v
If no:
a. Problem is in the SP Switch.
b. Go to “Step 0620-041” on page 1-35 to service or replace switch assembly.
Step 0620-020
The advanced diagnostics returned an SRN indicating that the diagnostics detected a problem.
1. Is this SRN the same as the previous SRN?
v
If yes, go to “Step 0620-011” on page 1-23 to perform service on the next highest priority component
in the list for this SRN.
v
If no, go to “Step 0620-012” on page 1-26 to service the new SRN.
Step 0620-021
An error message in the /var/adm/SPlogs/css/out.top file indicated that you either have an external
switch connection problem or a problem with a wrapped port. Priority 3 in Table 1-8 on page 1-22 directed
you to this step.
1. Check the specified jacks at the rear of the SP Switches for an obvious problem such as a loose
connection.
2. Pay special attention to cables that may have been moved recently.
3. Do connections appear to be okay?
v
If yes, go to “Step 0620-022”.
v
If no:
a. Fix the obvious connection problem.
b. Go to “Step 0620-043” on page 1-36 to verify fix.
Step 0620-022
The /var/adm/SPlogs/css/out.top file indicated a switch problem and all connection appeared to be okay.
Note: Be aware that in large systems, connections for SP Switches not in the multi-switch frame are
usually scattered throughout the out.top file.
1. If this is a multi-frame system, check the indicated jacks against the wiring charts for multi-frame
switch systems.
2. Is this a multi-frame system with problems reported on all switch data cables from one or more
switches?
v
If yes:
a. The problem may be caused by clocking or grounding between frames.
b. Go to “Step 0620-024” on page 1-30.
v
If no, go to “Step 0620-023”.
Step 0620-023
Some but not all switch data cables appear to be having problems.
1. Depending on whether the problem is a wrapped port or a switch-to-switch connection, perform one
of the following steps:
v
wrapped port (wrap plug installed): Remove the existing wrap plug. Install a different wrap plug on
the jacks indicated.
v
switch-to-switch connection: Disconnect the switch data cable from both ports indicated. Install
wrap plugs on the jacks indicated.
