Step 2 Check the model of the new network cable.
Step 3 Number the new cable.
● The new cable must have the same number as the old one.
● Use the same type of labels for optical cables. Record the name and number
of the local device to be connected on one side of a label and those of the
peer device on the other side. Attach a label 2 cm (0.79 in.) away from the
end of a network cable.
Step 4 Lay out the new cable in the same way as the old one.
● Lay out optical cables or SFP+ cables in the rack based on installation
regulations. You are advised to arrange cables in original mode. Ensure that
cables are routed neatly and intact.
● Separate optical cables or SFP+ cables from power cables and signal cables
when laying out the cables.
● Bend an optical cable or SFP+ cable with a bending radius of at least 4 cm
(1.57 in.) to prevent damage to core wires. Ensure that the cable is intact.
Ensure that optical cables or SFP+ cables are laid out for easy maintenance
and capacity expansion.
● Bind optical cables with cable ties. Ensure that optical cables are routed
straightly and bound neatly and that cable ties are installed at even spacing
and fastened properly.
Step 5 Connect the cable to an optical port.
When you use an optical cable:
1. Remove the old optical cable from the server.
2. Connect the new optical cable.
– Connect the new optical cable to the same port as the old one.
– Connect the optical cables to the optical module securely.
a. Insert the optical module into the optical port. See (1) in Figure 5-12.
b. Close the latch on the optical module to secure it. See (2) in Figure 5-12.
c. Insert the optical cable into the optical module. See (3) in Figure 5-12.
