to operate properly.
NOTE:
If the drive must be designated as the boot drive, connect the USB drive, restart the system, then enter the
System Setup Program and set the drive as first in the boot sequence (see "Using the System Setup Program" on
page 43). The USB device will be displayed in the boot order setup screen only if it is attached to the system before
you run the System Setup program.
Hard-Drive Features
Each server module supports one or two hot-pluggable SAS hard drives, or one or two hot-pluggable
SATA hard drives. See Figure 1-4 and Table 1-3 for information on the hard-drive indicators. Different
patterns are displayed as drive events occur in the system.
NOTICE:
Each server module must have a hard drive or a hard-drive blank installed in each hard-drive bay.
