replacement. When the hard disk drive status LED indicates a drive fault, you can replace a hot-swap drive without turning off the server. Each hot-swap drive that you plan to install comes mounted in a hot-swap-drive tray. The drive must have a single connector attachment (SCA) connector. Hot-swap-drive trays come with hot-swap drives. The hot-swap bays are connected to a SCSI backplane. This backplane is the printed circuit board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives.

replacement.
When the hard disk drive status LED indicates a drive fault, you can
replace a hot-swap drive without turning off the server.
Each hot-swap drive that you plan to install comes mounted in a hot-swap-drive tray.
The drive must have a single connector attachment (SCA) connector.
Hot-swap-drive
trays come with hot-swap drives.
The hot-swap bays are connected to a SCSI backplane.
This backplane is the printed
circuit board behind the bay.
The backplane controls the SCSI IDs for the hot-swap
drives.
The following illustration shows the hot-swap-drive backplane component locations, as
viewed from the front of the server.
Note:
The hard disk drive activity LED and hard disk drive status LED on the
backplane match the hard disk drive activity LED and hard disk drive status
LED on the hot-swap drive.
The following illustration shows the rear connectors on the hot-swap-drive backplane,
as viewed from the rear of the server.
Note:
When you install hot-swap hard disk drives, install them in the following order:
bay 7, bay 6, and bay 5.
