For More Information on Using Ethernet

Additional information, including setting up an Ethernet network or transferring ﬁles using

Ethernet, is available in Mac Help. Choose Mac Help from the Help menu and search for

“Ethernet” or “network.”

For information on networking products you can use with your Macintosh Server G4, go to

the Macintosh Products Guide at www.apple.com/guide

Putting the Server and Network Services to Sleep

For best performance, your server’s Energy Saver System Preferences are set so that the

server never sleeps. When the server is in sleep, network services are inaccessible and server

software cannot work. You can set the server to sleep after a certain period of inactivity, but

this is not recommended for server applications. Sleep is a state in which your server uses

very little power. If you would like to minimize power consumption but keep server software

and services available, use a screen saver program or turn off your monitor.

When the server is in sleep, the power button light on the front panel pulses. You wake the

server by pressing the power button on the front panel of the server or by pressing a key on

the keyboard. With some Apple monitors, you can also use the monitor power button to put

the server to sleep and wake it.

For more information about putting your server to sleep and other energy-saving options,

see Mac Help.

Connecting SCSI Devices to Your Server

Some Macintosh Server G4 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 four 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).
