Using USB Diskette or USB CD Drives

Each server module has a USB port on the front of the server module which allows you to connect a
custom cable for a diskette drive or USB CD drive. The USB drives are used to configure the server
module.
NOTICE:
The system supports only Dell-branded USB 1.1 or USB 2.0 drives. The drive must be horizontal and level
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.
NOTICE:
You cannot install a SAS drive and a SATA drive within a given server module (blade). However, you can
install server modules (blades) with SAS drives and server modules with SATA drives in the same server enclosure.
