Observing Operating Precautions; Booting The System From A Cd-Rom - Intergraph StudioZ GT RAX Setup Manual

38
If external RAID disk array cabinets are connected to the system, always power on or off the
system as follows:
Turn power on to the InterRAID cabinets first, listen for the audible beep, and then turn on
power to the system base unit.
Turn off power to the system base unit first, and then turn power off to the InterRAID
cabinets. If you turn power off to the InterRAID cabinets first, the RAID controller will read
the drives in those cabinets as dead the next time you turn power on to the system. If this
happens, refer to the Mylex documentation for drive recovery procedures.

Observing Operating Precautions

Observe the following precautions when operating the system:
When restarting the system, use the operating system controls instead of turning the power
switch off and on. Use the power switch only when instructed, or as the last alternative for
restarting the system.
Never turn off power to the base unit when the disk access LED is lit.
After turning off power to the base unit, wait at least 30 seconds before turning the power on
again. This allows the power supply to stabilize and the disk drives to stop spinning.

Booting the System from a CD-ROM

You can boot the system from a bootable CD-ROM if needed. However, you cannot set the
system's SCSI CD-ROM drive to be the permanent boot device.
NOTE You cannot install Windows NT 4.0 by booting from the Windows NT 4.0 CD-ROM,
which contains the wrong SCSI controller driver. You must use the Setup diskettes
to install Windows NT 4.0.
To boot the system from a bootable CD-ROM:
1. Insert the bootable CD-ROM in the system's CD-ROM drive.
2. Restart the system.
3. As the system boots -- for example, during the memory test or when the Intergraph Computer
Systems logo displays -- press
NOTE You must press
The system's SCSI CD-ROM drive does not display in the BIOS Setup program as a
boot device.
4. When a pop-up window displays a list of the system's boot devices, use the arrow keys to
highlight the SCSI CD-ROM drive, and then press
NOTE Do not select the ATAPI CD-ROM drive.
