2.2.5 Cabling Storage Servers

After the new Storage Servers are installed, you need to connect them to the existing equipment.

The following procedure describes how to cable the new equipment in the rack.

Note:

  • The existing cable connections in the rack do not change.

  • The blue cables connect to Oracle Database servers, and the black cables connect to Exadata Storage Servers. These network cables are for the NET0 Ethernet interface port.

  • Attach and route the management cables on the CMA and rear panel one server at a time. Do not slide out more than one server at a time.

  • Start from the bottom of the rack, and work upward.

  • Longer hook and loop straps are needed when cabling three CAT5e cables or two TwinAx cables.

  1. Attach a CMA to the server.

  2. Insert the cables into their ports through the hook and loop straps, then route the cables into the CMA in this order:

    1. Power

    2. Ethernet

    3. RDMA Network Fabric

  3. Route the cables through the CMA and secure them with hook and loop straps on both sides of each bend in the CMA.

  4. Close the crossbar covers to secure the cables in the straightaway.

  5. Verify operation of the slide rails and the CMA for each server:

    Note:

    Oracle recommends that two people do this step: one person to move the server in and out of the rack, and another person to watch the cables and the CMA.

    1. Slowly pull the server out of the rack until the slide rails reach their stops.

    2. Inspect the attached cables for any binding or kinks.

    3. Verify that the CMA extends fully from the slide rails.

  6. Push the server back into the rack:

    1. Release the two sets of slide rail stops.

    2. Locate the levers on the inside of each slide rail, just behind the back panel of the server. They are labeled PUSH.

    3. Simultaneously push in both levers and slide the server into the rack, until it stops in approximately 46 cm (18 inches).

    4. Verify that the cables and CMA retract without binding.

    5. Locate the slide rail release buttons near the front of each mounting bracket.

    6. Simultaneously push in both slide rail release buttons and slide the server completely into the rack, until both slide rails engage.

  7. Dress the cables, and then tie off the cables with the straps. Oracle recommends that you dress the RDMA Network Fabric cables in bundles of eight or fewer.

  8. Slide each server out and back fully to ensure that the cables are not binding or catching.

  9. Repeat the procedure for all servers.

  10. Connect the power cables to the power distribution units (PDUs). Ensure the breaker switches are in the OFF position before connecting the power cables. Do not plug the power cables into the facility receptacles now.
