Using Your Computer 49
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 open the Special menu and choose Sleep
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. 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 connect SCSI Ultra160 LVD hard disk drives only to the internal port
of the Dual Channel SCSI card. You can also 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 you can purchase and
install an additional SCSI PCI card to support the devices.
