l 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 an optical cable and those of the peer device on the
other side. Attach a label 2 cm (0.79 in.) away from the end of an optical cable.
Step 3 Lay out the new cable.
Lay out the new cable in the same way as the old one. Note the following points:
l Lay out optical or SFP+ cables in the cabinet according to installation regulations. You
are advised to arrange new cables in the same way as existing cables. Ensure that cables
are routed neatly and intact.
l Separate optical or SFP+ cables from power and signal cables when laying out the
cables.
l Bend an optical 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 or SFP+ cables
are laid out for easy maintenance and capacity expansion.
l 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 4 When you use an optical cable:
1. Remove the old optical cable.
Remove the old optical cable from the server.
2. Connect the new optical cable.
NOTE
l Connect the new optical cable to the same port as the old one.
l Connect the optical cable to the optical module securely.
1. Insert the optical module into the optical port. See step (1) in Figure 3-23.
