Do not install hot-swap drives into a simple-swap server model, it is notsupported.v The simple-swap server models are available only in non-RAID configurations.v The electromagnetic interference (EMI) integrity and cooling of the server areprotected by having all bays and PCI and PCI Express slots covered oroccupied. When you install a drive, PCI, or PCI Express adapter, save the EMCshield and filler panel from the bay or PCI or PCI Express adapter slot cover inthe event that you later remove the device.To install a simple-swap SATA hard disk drive, complete the following steps:1.
