•
Remove any jewelry or metal objects from your body because they are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit boards or
areas where power is present.
•
Do not lift the expansion enclosure chassis by the handles of the power supply units (PSUs). They are
not designed to hold the weight of the entire chassis, and the chassis cover may become bent.
•
Before moving the expansion enclosure chassis, remove the PSUs to minimize weight.
•
Do not remove drives until you are ready to replace them.
NOTE: To ensure proper expansion enclosure cooling, hard drive blanks must be installed in any
hard drive slot that is not occupied.
