Installing System Components
Removing a RAID Battery
1 Disconnect the cable between the RAID battery and the SAS RAID controller daughter card. See
Figure 3-12.
2 Press down and to the left on the battery carrier to disengage the carrier from the chassis battery carrier
slots.
3 Gently pulling back the two guides holding the RAID battery into the battery carrier, draw out the
RAID battery from the battery carrier.
Configuring the Boot Device
NOTE:
System boot is not supported from an external device attached to a SAS or SCSI adapter. See
support.dell.com for the latest support information about booting from external devices.
If you plan to boot the system from a hard drive, the drive must be attached to the primary (or boot)
controller. The device that the system boots from is determined by the boot order specified in the System
Setup program.
The System Setup program provides options that the system uses to scan for installed boot devices. See
"Using the System Setup Program" on page 37 for information about the System Setup program.
Internal USB Memory Key Connector
The system provides an internal USB connector located on the sideplane board for use with the optional
bootable USB flash memory key (see Figure 6-4). To boot from the USB memory key, you must specify the
USB device in the boot sequence in the System Setup program. See "System Setup Options" on page 38. For
information on creating a bootable file on the USB memory key, see the user documentation that
accompanied the USB memory key.
Installing the Optional Internal USB Memory Key
CAUTION:
Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. See your Product Information Guide for complete information about safety
precautions, working inside the computer, and protecting against electrostatic discharge.
1 Turn off the system, including any attached peripherals, and disconnect the system from its electrical
outlet.
2 Open the system. See "Opening the System" on page 55.
3 Remove the SAS controller card. See "Removing a SAS Controller Daughter Card" on page 68.
4 If present, disconnect the optical drive cable from the sideplane board.
NOTE:
You do not need to disconnect the control panel cable from the sideplane to complete the memory key
installation.
5 Press inward on the sideplane release tabs, lift the sideplane up enough to clear the system board pins,
and rotate the end of the sideplane upward. See Figure 3-32.
