Caution - Data cables must never turn tighter than a 5-inch (127 mm) radius. A tighter radius damages the wires and fibers inside the cable.
Note - When you install the data cables, connect cables to the lower connectors first, then connect cables to the upper connectors.
Note - Though the illustrations in this procedure picture only InfiniBand data cables, the process is identical for both InfiniBand data cables and Ethernet splitter data cables.
The shell should not be bent and should be parallel to the inner boards. If the connector is bent or damaged, use a different cable.
Ensure that the L groove is up for the top row of receptacles, or that the L groove is down for the bottom row of receptacles.
Note - On some QSFP cable connectors, there is a retraction strap. Both the retraction strap and L groove indicate the reference surface for the connector. When installing QSFP cables in the top row of receptacles (0A, 1A, 2A, and so on), ensure that the L groove and retraction strap are up. When installing QSFP cables in the bottom row of receptacles (0B, 1B, 2B, and so on) ensure that the L groove and retraction strap are down. See Switch Service, identifying the data cable.
As you slide the connector in, the shell should be in the center of the QSFP receptacle.
Use hook and loop fastener straps to bundle and secure the cables.
Note - Do not use cable zip ties to bundle or secure the cable, because the ties damage the fibers inside the cable.
If the Link LED is unlit, the link is down. If the Link LED flashes, there are symbol errors. See Switch Administration, checking the link status LEDs.
