Step 3 Lay out the new cable.
Lay out the new cable in the same way as the old one. Note the following points:
● Lay out optical or QSFP+ cables in the cabinet by observing installation
regulations. You are advised to arrange new cables in the same way as
existing cables. Ensure that cables are routed neatly and intact.
● Separate optical or QSFP+ cables from power and signal cables when laying
out the cables.
● Bend optical or QSFP+ cables with a bending radius of at least 4 cm (1.57 in.)
to prevent damage to core wires. Ensure that the cable sheath is intact. Lay
out optical or QSFP+ cables for easy maintenance and capacity expansion.
● Bind optical cables with cable ties. Ensure that optical cables are bound
closely, neatly, and straight, and cable ties are in even distance and fastened
properly.
Step 4 Replace the cable.
1. Remove the old 56G IB cable.
Release the latch and remove the cable. See Figure 3-20.
Figure 3-20 Removing a 56G IB cable (using an IB FlexIO card with two 56G
ports as an example)
2. Connect the new 56G IB cable.
Remove the dust-proof cap on the port, and insert the cable connector into
the port. See Figure 3-21.
When you hear a "click" and the cable cannot be pulled out, the connector is secured.
