Connecting Speakers and a Microphone
If the system includes separate powered speakers and a microphone, connect the speakers to
the Line Out port on the audio card, and connect the microphone to the Microphone port on
the audio card. Connect the speaker power AC adapter to the appropriate speaker(s), and
then to a grounded, three-prong AC wall outlet. See the audio card documentation delivered
with the system for more detailed connection information.
If the system includes a multimedia keyboard, see the multimedia keyboard documentation
delivered with the system for connection information.
Connecting an External SCSI Device
Two SCSI adapters are available as options for the TDZ 2000 GL2: a dual channel Ultra
Wide option, and a single channel Low-Voltage Differential (LVD) option. If your system
includes one of these SCSI adapters, you can connect internal and external SCSI devices,
such as hard disk drives or tape drives, to the system. Internal SCSI devices included in the
system are already connected to the internal connector of the SCSI adapter. You can connect
external devices to the external connector on the SCSI adapter.
NOTE The system BIOS will attempt to start the system using a hard disk drive connected to the
bootable SCSI adapter in the lowest PCI slot. To start the system using an external SCSI
hard disk drive, you must ensure the drive’s SCSI adapter is installed lower in slot order than
all other bootable SCSI adapters
The Ultra Wide SCSI adapter provides a maximum data transfer rate of 40 MB per second.
If you connect a non-Ultra Wide SCSI device to the adapter, data transfer rates are limited to
the speed of that device.
The LVD SCSI adapter provides a maximum data transfer rate of 80 MB per second. If you
connect a non-LVD SCSI device to the adapter, data transfer rates are limited to the speed of
that device.
CAUTION Using a non-compliant SCSI-1 device with your system may cause your system to stop
working or lead to other unpredictable results.
You can connect up to 15 external SCSI devices to an installed SCSI adapter. However, the
number of drives and length of the cables used to connect the drives is limited in most SCSI
modes. SCSI-2, Ultra SCSI, and Ultra SCSI impose shorter cable restrictions than SCSI-1.
