Installing or replacing an expansion canister
You can reinstall an expansion canister in a 5U92 disk 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 5U92 disk enclosure and the system. The
expansion enclosure contains two expansion canisters. Figure 61 on page 62 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.
