Removing an expansion canister: 2145-92F
You can remove the expansion canisters in a 2145-92F expansion enclosure.
Before you begin
Important: You can remove an expansion canister without powering off the
expansion enclosure. However, to maintain operating temperature, perform the
following tasks.
v Do not remove a faulty expansion canister until its replacement is ready to be
installed.
v 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 2145-92F expansion
enclosure and SAN Volume Controller system. If either of the two expansion
canisters has a failure, the other expansion canister assumes the full I/O load.
Figure 115 shows the features of an expansion enclosure.
