You can install or replace a drive without turning off the storage array, which helps you avoid significant interruption to the operation of the system. The EMI integrity and cooling of the storage array are protected by having all drive bays covered or occupied. The number of the installed drives in your storage array varies depending on the storage array model. The vacant bays are occupied by dummy drive trays. When you install a drive, save the removed dummy drive tray from the drive bay in the event that you later remove the drive and need the dummy drive tray to cover the place. Attention: An unoccupied drive bay without any other protection might impact the EMI integrity and cooling of the storage array, which might result in overheating or component damage. To maintain the EMI integrity and cooling of the storage array, install a new drive as soon as you remove the failing one or the dummy drive tray. Before you begin, review the following drive installation rules: • Follow the order of the drive bays when installing a drive. See "Front view of the storage array" on page 10 to locate the drive bays in your storage array. • For drives with different capacities, install the drive by following the order of the drive bays as well as the order from the lowest capacity to the highest capacity. Before you begin, print all the related instructions or ensure that you can view the PDF version on another computer for reference.
