e. For the loop with the failure, select Resources associated with loop .
f. For the HSL I/O Bridge with the resource name that you recorded, select Associated packaging
resources.
g. Record the frame ID and card position. Record this information for the first failing link in HSL link
status diagnosis form.
h. Select Display detail, and record the card position for the first failing resource.
9. Find the information for the other (second) failing resource by following these steps:
a. Record this information as the second failing resource on the link.
b. Select Cancel—>Cancel to return to the Logical hardware associated with HSL loops display.
c. Move the cursor to the HSL I/O Bridge with the name of the first failing resource, and select
Display detail—>Include non-reporting resources.
d. Follow the failed port by doing the following:
v If the leading port is failed, select Follow leading port.
v If the trailing port is failed, select Follow trailing port.
e. You have located the second failing resource on the link.
f. Record the resource name, card type-model, and part number.
g. In HSL link status diagnosis form, record the link status of each port in column A for the second
failing link. Circle 'Internal' if the port is designated as internal.
h. Select Cancel to return to the Logical hardware associated with HSL loops display.
i. Select Include non-reporting resources—>Associated packaging resources for the HSL I/O
Bridge or Network Interface Controller (NIC) with the resource name that you recorded for the
second failed resource.
j. Record the frame ID (if present), card position, and port. Record this information for the second
failing link in HSL link status diagnosis form.
k. Select Display detail and record the card position for the second failing resource.
10. Have you repeated steps 2 (See page 82) through 9 (See page 83) for a second time during this
procedure?
v No: Do the first failing link and the second failing link have the same frame ID?
– No: Continue with the next step to determine if the HSL cable connectors between the first and
second failing resources are properly seated and cleaned.
– Yes: Return to the procedure which sent you here.
This ends the procedure.
v Yes: Return to the procedure that sent you here.
This ends the procedure.
11. Disconnect the cable at the frame ID, card position, and port that you recorded for the first failing
resource.
12. Is the connection an optical link?
v No: Wait at least 30 seconds, and then continue with the next step.
v Yes: Clean the HSL cable connector and port using the tools and procedures listed in symbolic
FRU "OPT_CLN" on page 407. Then, continue with the next step.
13. Reconnect the cable to the port.
Attention: You must fully connect the cable and tighten the connector's screws within 30 seconds of
when the cable makes contact with the port. If you do not, the link will fail and you must disconnect
and reconnect it again. If the connector screws are not tightened errors will occur on the link and it
will fail.
14. Disconnect the cable at the frame ID, card position, and port that you recorded for the second failing
resource.
15. Is the connection an optical link?
