Connecting a Cable to an Optical Port

You can connect an optical or SFP+ cable to an optical port. You need to first determine the type of the cable to be connected.

1. Put on an ESD wrist strap. For details, see ESD Protection.
2. Check the model of the new cable.
3. Number the new cable.
   • The new cable must have the same number as the existing one to be replaced.
   • Use the same type of labels for network cables. Record the name and number of the local device 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.

4. Route the new cable.

   Route the new network cable in the same way (underfloor or overhead) as the old one.

   • Route optical or SFP+ cables in the cabinet based on the installation requirements. You are advised to arrange new cables in the same way as existing cables. Ensure that the cables are routed neatly without damage to the cable sheath.
   • Separate optical or SFP+ cables from power and signal cables when routing the cables.
   • Bend optical or SFP+ 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. Ensure that optical or SFP+ cables are properly routed for easy maintenance and capacity expansion.
   • Bind cables with ties when routing. Ensure that optical cables are routed straightly and bound neatly, and that cable ties are installed at even spacing and fastened properly.

5. Connect the cables to the optical ports.

   When you use an optical cable:

   1. Remove the optical cable to be replaced.

      Remove the existing 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 cable to the optical module securely.
      1. Insert the optical module into the optical module port. See (1) in Figure 5-12.
      2. Close the latch on the optical module to secure it. See (2) in Figure 5-12.
      3. Insert the optical cable into the optical module. See (3) in Figure 5-12.

   When you use an SFP+ cable:

   1. Remove the SFP+ cable to be replaced.

      Gently push the power connector inwards and pull the latch out to remove the cable. See Figure 5-13.

      Do not directly pull out the latch.

   2. Connect the new SFP+ cable.

      Remove the dustproof cap from the port, and insert the cable connector into the port. See Figure 5-14.

      When you hear a "click" sound and the cable cannot be pulled out, the connector is secured.

6. Check whether the new cable is properly connected.

   Power on the device, and ping the peer device connected by the new network cable. If the peer device cannot be pinged, check whether the network cable is damaged or the connectors are not securely connected.

7. Bind the new optical cable.

   Bind the new network cable in the same way as the existing network cables. You can also remove all cable ties and bind all of the optical cables again if necessary.
