Racking the hardware components

If you have not received the equipment already installed in cabinets, you must rack the components.

1. Plan out the positioning of the MetroCluster components.
   The rack space will depend on the platform model of the storage controllers, the switch types, and the number of disk shelf stacks in your configuration.
2. Properly ground yourself.
3. Install the storage controllers in the rack or cabinet.

4. Install the FC switches in the rack or cabinet.
5. Install the disk shelves, power them on, and set the shelf IDs.

   • You must power-cycle each disk shelf.
   • Shelf IDs must be unique for each SAS disk shelf within the entire MetroCluster configuration (including both sites).
6. Install each FC-to-SAS bridge:
   1. Secure the "L" brackets on the front of the bridge to the front of the rack (flush-mount) with the four screws.
      The openings in the bridge "L" brackets are compliant with rack standard ETA-310-X for 19-inch (482.6 mm) racks.

      For more information and an illustration of the installation, see the ATTO FibreBridge 6500N Installation and Operation Manual.

   2. Connect each bridge to a power source that provides a proper ground.
   3. Power on each bridge.
      Note: For maximum resiliency, ensure that bridges attached to the same stack of disk shelves are connected to different power sources.

      The bridge Ready LED might take up to 30 seconds to illuminate, indicating that the bridge has completed its power-on self test sequence.
