Failed Environmental Card Canister

What Caused the Problem?
One or more environmental cards have failed in a drive enclosure.
If the only environmental card or both environmental cards have failed in the same drive enclosure, all I/O to the drive enclosure will fail. If the drive enclosure has two environmental cards, and only one has failed, you can continue to operate the drive enclosure, but should replace the failed canister as soon as possible.
