    Chapter 3 Performing a Cable Inventory 3.3 Performing a Cable Inventory Collect and inventory the cables you ordered, if any. You should inventory spare cables from the kit and the existing multirack cables. Each Exalogic machine includes a kit of spare parts. Some spare cables are used for multirack cabling.

  • Page 23: Multirack Cabling Tasks

    Before you can set up the multirack cabling, you must first shut down the affected Exalogic machines and Exadata Database Machines. Consider the operational impact of shutting down the systems, and take appropriate action. Refer to the Oracle Exalogic Elastic Cloud Machine Owner's Guide and the Exadata Database Machine documentation for shutdown procedures.

    Chapter 4 Unbundling the Inter-Switch Cables 4.4 Unbundling the Inter-Switch Cables Unbundle the inter-switch cables. Remove the cable ties holding the cables together, such as hook-and-loop fasteners. Lay the cables out gently in collections of like length. Observe safety precautions. Be careful when handling the cables to avoid cable damage.
