Installing An Optional 5U Sas Expansion Enclosure; Safety Notices And Considerations: 2077-92F - IBM Storwize V5000 Gen2 Quick Installation Manual

• A connected port on the node canister must connect to a single port on an expansion canister. Cables
that split the connector out into separate physical connections are not supported.
• Attach cables serially between enclosures; do not skip an enclosure.
• The last enclosure in a chain must not have cables in port 2 of canister 1 and port 2 of canister 2.
• Ensure that cables are installed in an orderly way to reduce the risk of cable damage when replaceable
units are removed or inserted.
See "Connecting expansion enclosures to the control enclosure" on page 21 for examples of SAS cable
connections on each system.
For information about the SAS cabling requirements for 5U expansion enclosures, see "Connecting the
optional 5U expansion enclosure: 2077-92F " on page 106.
