Replacing a 6780 Switch
2. Label the connectors of the replacement cable with the cluster switch names and
port numbers to which the suspected bad cable is connected (such as X11, slot 12,
port 1 at one end, and X13, slot 12, port 1 at the other end).
If necessary, refer to the cabling tables in Appendix B, Cable Connections in a
Layered Topology.
3. Physically route the replacement cable along the same path as the suspected bad
cable.
4. Disconnect the suspected bad cable at both ends.
5. If the connectors on the replacement cable have dust caps, remove the dust caps
and install them on the connectors of the suspected bad cable.
6. Connect the replacement cable as labeled in Step 2.
7. Confirm that the link-alive LED lights at both ends. The link-alive LEDs should light
within a few seconds. If the link-alive LEDs do not light:
•
Try reconnecting the cable, using care to align the key on the cable plug with
the connector.
•
If possible, try connecting a different cable.
8. Direct ServerNet connectivity is automatically restored after an interval of
approximately 50 seconds times the number of nodes in the cluster (25 seconds
for nodes running G06.14 or later). If you do not want to wait, you can manually
force recovery of ServerNet connectivity:
SCF START SERVERNET $ZNET
9. Repeat Step 1 to confirm that IPC connectivity is up between all nodes on both
fabrics.
10. If connectivity problems continue with the cable, contact your service provider.
