- Warning The SGI InfiniteStorage 15000 MUST be grounded before applying power.
- Warning To ensure protection against electric shock caused by HIGH LEAKAGE CURRENT (TOUCH CURRENT), the SGI InfiniteStorage 15000 must be connected to at least two separate and independent sources. This is to ensure a reliable earth connection.
- Warning To ensure your system has warning of a power failure please disconnect the power from the power supply, by either the switch (where present) or by physically removing the power source, prior to removing the PCM from the enclosure/shelf.
- Warning Do not remove covers from the PCM. Danger of electric shock inside. Return the PCM to your supplier for repair.
- Warning Operation of the Enclosure with ANY modules missing will disrupt the airflow and the drives will not receive sufficient cooling. It is ESSENTIAL that all apertures are filled before operating the unit.
- Important Observe all applicable safety precautions, e.g. weight restrictions, handling batteries and lasers etc., detailed in the preceding paragraphs when dismantling and disposing of this equipment
- Important SGI InfiniteStorage 15000 drive enclosures should only be installed in SGI InfiniteStorage 15000 racks. Mounting and installing these drive enclosures in any other rack is not authorized or supported by SGI.
- Warning It is recommended that you do not slide more than one enclosure out of the rack at a time, to avoid danger of the rack tipping over.

- Controller Installation
- 1. Unpack the controller system.
- 2. If it is necessary to install the controller in the 19-inch cabinet(s), contact your service provider.
- 3. Set up and connect the drive enclosures to the controller.
- 4. Connect the controller to your Infiniband (IB) or Fibre Channel (FC) switch and host computer(s).
- 5. Connect your RS-232 terminal to the controller.
- 6. Power up the system.
- 7. Configure the storage array (create and format LUNs - Logical Units) via RS-232 interface, Telnet, or GUI.
- 8. Define and provide access rights for the clients in your SAN environment. Shared LUNs need to be managed by SAN management software. Individual dedicated LUNs appear to the client as local storage and do not require management software.
- 9. Initialize the system LUNs for use with your server/client systems. Partition disk space and create file systems as needed.
