• Do not remove a faulty expansion canister until its replacement is ready to be installed.
• Do not remove an expansion canister from an operational enclosure for more than approximately 10
minutes. The reduction in airflow through the enclosure might cause the enclosure or its components to
shut down to protect from overheating.
About this task
An expansion canister provides SAS connectivity between the 2076-92F expansion enclosure and
Storwize V7000 system. If either of the two expansion canisters has a failure, the other expansion
canister assumes the full I/O load. Figure 107 on page 97 shows the features of an expansion enclosure.
