keeping a 3650 comfortable?

can anyone offer guidelines on acceptable environmental
operating conditions for a 3650? i.e. temperature/humidity range.
thanks.

The worst case operating conditions are based on what the disk drive and
tape drives can handle. We use the following table for 3640 and 3650
