When you install a drive, PCI, or PCI Express adapter, save the EMCshield and filler panel from the bay or PCI adapter or PCI Express adapter slotcover in the event that you later remove the device.Installing a hot-swap hard disk driveTo install a hot-swap SAS or SATA hard disk drive, complete the following steps.Note: If you have only one hard disk drive, you must install it in the upper-left bay.1.
