Installing or replacing an expansion canister: 2077-92F
You can reinstall an expansion canister in a 2077-92F expansion enclosure or replace a faulty expansion
canister with one from FRU stock.
Before you begin
Important: You can replace an expansion canister without powering off the expansion enclosure.
However, to maintain operating temperature, replace the expansion canister within 10 minutes of its
removal. When an expansion canister is removed, 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 2077-92F expansion enclosure and
Storwize V5000 Gen2 system. The expansion enclosure contains two expansion canisters. Figure 40 on
page 49 shows an example of an expansion canister. If either of the two expansion canisters has a
failure, the other expansion canister assumes the full I/O load.
