If you have installed expansion enclosures, you must connect them to a
control
enclosure.
Before you begin
If you purchased disk drives that were not preinstalled for you, you must
install all of the drives
before connecting the SAS cables to the expansion
enclosures.
About this task
This task applies if you are installing one or more expansion enclosures.
You can attach up nine expansion enclosures to the
control enclosure.
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.
Procedure
To install the cables, complete the following steps.
- Using the
supplied SAS cables, connect the control enclosure to the first expansion
enclosure as shown in Figure 1.
- Connect SAS port 4 of the left node canister in the
control enclosure to SAS port 1 of the left expansion canisters in
the first expansion enclosure.
- Connect SAS port 4 of the right node canister in the
control enclosure to SAS port 1 of the right expansion canisters in
the first expansion enclosure.
Figure 1. Connecting
the SAS cables
- If additional expansion enclosures are installed, connect each one to the previous expansion
enclosure, as shown in Figure 1.
- Use one cable to connect SAS port 2 of the left expansion canister in the previous
expansion enclosure to SAS port 1 of the left expansion canister in the newly installed expansion
enclosure.
- Use the second cable to connect SAS port 2 of the right expansion canister in the
previous expansion enclosure to SAS port 1 of the right expansion canister in the newly installed
expansion enclosure.
Note: A control enclosure can support up to nine expansion enclosures.
