Connecting SAS cables to expansion enclosures
If you have installed expansion enclosures, you must connect them to a control enclosure.
This task applies if you are installing one or more expansion enclosures. Each control enclosure in the
system can manage two sets of expansion enclosures; each set can consist of a maximum of 10 expansion
enclosures. Therefore, each control enclosure can manage up to 20 expansion enclosures. A system that
contains two control enclosures can have up to 40 expansion enclosures.
Note: When connecting SAS cables between enclosures, you must follow a list of guidelines to ensure
that your configuration is valid. Do not begin connecting the cables until you have read "SAS cabling
guidelines" on page 23.
To install the cables, complete the following steps.
Step 1.
Using the supplied SAS cables, connect the control enclosure to the expansion enclosure at
rack position 1, as shown in .
a.
Connect SAS port 1 of the left node canister in the control enclosure to SAS port 1 of the left
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.
