2. Take the following actions to connect Controller 0A to its related expansion modules. The example below
has 3 expansion enclosures directly below the storage enclosure.
IMPORTANT Best practice is to use the expansion Port A for input and Port C for output.
a. Insert a mini-SAS data cable into the left controller, Controller 0A, then connect the other end to SAS
port A in the first expansion enclosure, 1A.
b. Insert a mini-SAS data cable from SAS port C in the first expansion enclosure, 1A, and connect the other
end to SAS port A in the second expansion enclosure, 2A.
c. Insert a mini-SAS data cable from SAS port C in the second expansion enclosure, 2A, and connect the
other end to SAS port A in the third expansion enclosure, 3A.
3. Take the following actions to connect Controller 0B to its related expansion modules.
IMPORTANT Best practice is to use the expansion Port A for input and Port C for output.
a. Insert a mini-SAS data cable into the right controller, Controller 0B, and connect the other end to SAS
port A in the third expansion enclosure, 3B.
b. Insert a mini-SAS data cable from SAS port C in the third expansion enclosure, 3B, and connect the
other end to SAS port A in the second expansion enclosure, 2B.
c. Insert a mini-SAS data cable from SAS port C in the second expansion enclosure, 2B, and connect the
other end to SAS port A in the first expansion enclosure, 1B.
