Installing or replacing an expansion canister: 2145-92F
You can reinstall an expansion canister in a 2145-92F 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 2145-92F expansion
enclosure and SAN Volume Controller system. The expansion enclosure contains
two expansion canisters. Figure 59 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.
