To put your computer to sleep, you can
m press the power button on the front of the computer
m select a sleep mode in the Energy Settings portion of the Control Strip
m choose Sleep from the Special menu
When the computer is in sleep, the front panel power button light pulses.
You wake the computer by pressing the power button on the front panel of the computer or
by pressing a key on the keyboard. With some Apple monitors, you can also use the monitor
power button to put the computer to sleep and wake it.
Not all PCI cards or replacement AGP cards comply with the computer’s power management
standards. If you install a non-compliant card, the computer can still enter sleep mode, but it
will not achieve maximum energy savings. You can use the Apple System Profiler to find out
whether an installed card is compliant.
For more information about energy-saving options, see Mac Help.
Attaching SCSI Devices to Your Computer
Some Power Mac G4 computer configurations come with an Ultra160 Dual Channel SCSI
card installed in a PCI slot with one or more internal SCSI hard disks connected to it. You can
install additional internal SCSI hard disk drives up to a maximum of three drives. It’s
recommended that you only connect SCSI Ultra160 LVD hard disk drives to the internal port
of the Dual Channel SCSI card. You can connect external SCSI devices, including older drives
with slower data transfer rates, to the external port of the Ultra160 Dual Channel SCSI card.
Because the card has two channels, one connected to the internal port and another
connected to the external port, connecting older devices to the external port doesn’t slow
down the transfer rate of the internal hard disk drives.
Apple recommends that you use only SCSI Ultra160 LVD devices as internal hard disk drives.
To connect older SCSI devices that use a 25-pin or a 50-pin connector—such as Zip drives,
scanners, or DAT drives—you need to purchase SCSI adapters, or purchase and install an
additional “legacy” SCSI PCI card (one that supports older devices).
