Dell OptiPlex GXa Systems Service Manual
1-4
The low-profile chassis can only accommodate one external drive device
(diskette drive or tape drive). Other chassis configurations can accommodate
two external drive devices.
NOTE: If the diskette drive and tape drive are both attached to the diskette drive
controller on the system board, only the diskette drive is configured in the
System Setup program as Drive A or Drive B. The tape drive will then be listed
as Not Installed (under either the Drive A or Drive B category).
Built-In SVGA Subsystem
The Dell OptiPlex GXa systems include a built-in high-performance 64-bit
accelerated graphics port (AGP) subsystem, implemented on the system board,
which drives an external SVGA monitor. The AGP contains a dedicated bus
that bypasses the PCI bus and allows for interconnection of the video subsystem
directly to the Pentium chip set for extra high performance required for 3D
video subsystems. This architecture also off-loads the PCI bus providing greater
performance for devices attached to the PCI bus.
The maximum supported resolutions include 1600 x 1200 pixels with 256 col-
ors noninterlaced and 1024 x 768 pixels with 65,536 colors noninterlaced. The
SVGA subsystem consists of the following major components:
•
ATI 3D Rage Pro SVGA video controller
•
2-MB synchronous graphics random-access memory (SGRAM) video
memory (expandable to 4 MB via a video-memory upgrade kit)
•
15-pin monitor port
Built-In Audio Controller
The built-in audio controller is a single chip that connects to the ISA bus. The
audio controller has analog jacks for line-in and microphone input. The single
line-out output jack provides stereo output for a line-level input to an external
amplifier or drives stereo headphones. See "Technical Specifications" found
later in this chapter for audio jack input and output specifications.
Built-In Ethernet NIC Support
The Dell OptiPlex GXa systems have an integrated 10/100-Mbps 3Com
3C905 Ethernet NIC subsystem. The subsystem supports both the 10BASE-T
and 100BASE-T standards. The NIC subsystem connects to the Ethernet net-
work through a single RJ45 connector on the back of the computer. The RJ45
connector and the NIC interface circuitry are mounted on the system board.
The NIC connector on the computer's back panel has the following indicators:
•
A yellow activity indicator flashes when the system is transmitting or
receiving network data. (A high volume of network traffic may make this
indicator appear to be in a steady "on" state.)
•
A green link integrity indicator lights up when there is a good connection
between the network and the NIC. When the green indicator is off, the sys-
tem is not detecting a physical connection to the network.
