Installation Guidelines

Follow these guidelines when installing the IBM SAN32C-6 switch:

  • Plan your site configuration and prepare the site before installing the switch.
  • Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate airflow. The airflow requirements are listed the Airflow Considerations section.
  • Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and sends out air to the hot aisle. For more information, see the Airflow Considerations section.
  • Ensure that the air-conditioning meets the heat-dissipation requirements listed in the Airflow Considerations section.
  • Ensure that the cabinet or rack meets the requirements listed in the Cabinet and Rack Requirements section.
  • Ensure that the chassis is adequately grounded. If the switch is not mounted on a grounded rack, we recommend that you connect both the system ground on the chassis and the site power ground to an earth ground.
  • Ensure that the site power meets the power requirements listed in the Switch Specifications. If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
    CAUTION:

    Avoid UPS types that use ferro-resonant technology. These UPS types can become unstable with systems such as the IBM Storage Networking SAN c-type Family, which can in turn have substantial current draw fluctuations because of fluctuating data traffic patterns.

  • Ensure that circuits are sized according to local and national codes.

    For North America, the 650-W power supplies require a 15-A circuit. If you are using a 200 or 240 VAC power source in North America, the circuit must be protected by a two-pole circuit breaker.

    CAUTION:

    To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power to the switch are within current ratings for wiring and breakers.

  • As you install and configure the switch, record the information.
