Connecting an additional monitor
You can use an additional monitor with your server if you install a video
expansion card. See “Installing an Expansion Card” earlier in this chapter
for instructions.
When you connect an additional monitor:
m Make sure that the ventilation openings on the server and the monitors are
clear and unobstructed.
m If necessary, configure the monitor options. See the documentation that
accompanied the monitor and “Configuring Your Monitor” in Chapter 1 of
the Wo rk gr oup Server Administrator’s Guide.
m If there is interference on your screens or on a television or radio near your
server, reposition or separate the affected equipment.
Connecting a trackball or other input device
Your server has an Apple Desktop Bus (ADB) port, which you use to connect
the mouse, the keyboard, and other input devices such as a trackball, a bar-
code reader, or a graphics tablet.
You can usually connect up to three ADB devices in a chain to a single port.
The exact number depends on how much power the devices require.
IMPORTANT
The total power used by all ADB devices connected to your
server must not exceed 500 milliamperes (mA). Information about the power
requirements of the mouse and keyboard are in Appendix B, “Technical
Information.” Check the information that came with your other ADB devices
for power requirements.
