Requirements for completing the redundant AC-power switch connection chart

If you are using the optional redundant AC-power switch feature, you must fill out the redundant AC-power switch connection chart before this feature can be installed.

  1. Download the redundant AC-power switch connection chart:
  2. Go to: www.ibm.com/support.
  3. Under Support shortcuts, click Plan and install documentation.
  4. In the search box, type and search for IBM System Storage SAN Volume Controller Planning Information; then click on the search result.
  5. Click the desired link to download it to your computer.

Determine if you want to use the redundant AC-power switch to power one or two nodes. If you plan to power two nodes, the nodes must be in different I/O groups. Therefore, a clustered system with a single I/O group requires two redundant AC-power switch units.

You must plan the route of the input power cables for the redundant AC-power switch units. These cables are connected to the front edge of the redundant AC-power switch and must be routed to the power distribution unit for the rack. You might have to leave a free slot in the rack to allow the cables to run from front to back.
