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 only supports USB 1.1 drives designated by Dell for use with your system. The drive must be horizontal and level to operate
properly.
NOTE:
If the drive must be designated as the boot drive, enter the System Setup Program and set the drive as first in the boot sequence (see
the System Setup
Program"). Reset the power on the server module.
Hard-Drive Features
Each server module supports up to two hot-pluggable SCSI hard drives. If only one hard drive is used, a blank must be installed to maintain proper cooling.
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.
NOTE:
Each server module must have a hard drive or a hard-drive blank installed in each hard-drive bay.
