Each set of expansion enclosures is connected together sequentially through the IN and OUT SAS ports,
forming a chain with a control enclosure at the end of the chain.
Note: When you connect SAS cables between enclosures, review and follow the guidelines to ensure that
your configuration is valid. Do not begin connecting the cables until you read "SAS cabling guidelines" on
page 67.

expansion canister in the first expansion enclosure.
b) Connect SAS port 1 of the right node canister in the control enclosure to SAS port 1 of the right
expansion canister in the first expansion enclosure.
