Connecting the Two-Lane Links
5. One cable at a time, connect the cable ends. Table 4-24 shows the cable
connections.
6. Check the link-alive LED near each PIC port. The link-alive LEDs should light a few
seconds after the cable is connected at both ends. If the link-alive LEDs do not
light:
a. Try reconnecting the cable, using care to align the key on the cable plug with
the PIC connector.
b. Make sure the dust caps are removed from the cable ends.
c. If possible, try connecting a different cable.
7. Continue until all cables on a fabric are connected.
Caution. During an upgrade from a split-star topology to a tri-star topology, you must first
connect all cables on the X fabric and then wait for the guided procedure to prompt you to
connect the cables on the Y fabric.
