Step 2.
To add a second expansion enclosure chain to the control enclosure, use the supplied SAS cables
to connect the control enclosure to the expansion enclosure at rack position 2. Refer to Figure
20 "Connecting the SAS cables" on page 22 for an example.
a.
Connect SAS port 2 of the left node canister in the control enclosure to SAS port 1 of the left
expansion canister in the second expansion enclosure.
b.
Connect SAS port 2 of the right node canister in the control enclosure to SAS port 1 of the
right expansion canister in the second expansion enclosure.
Step 3.
If additional expansion enclosures are installed, connect each one to the previous expansion
enclosure in a chain; use two Mini SAS HD to Mini SAS HD cables, as shown in Figure 20
"Connecting the SAS cables" on page 22.
Note: A control enclosure can support up to 20 expansion enclosures (10 above the control
enclosure and 10 below the control enclosure).
Step 4.
If additional control enclosures are installed, repeat this cabling procedure on each control
