Data cables should not be located near high voltage power lines, power transformer
telephone cables, or in elevator shafts. They should not cross walkways. If you must
cross walkways, cover the cables with a cable bridge.
You must also take cable lengths into consideration. Single-ended circuits are
susceptible to all forms of electromagnetic interference. As line length increases beyond
fifty feet, the reliability of the RS232C cable connected to the terminal and printer
decreases rapidly. If local terminals are to be located further than fifty feet from the
computer, we recommend you use low capacitance twisted-paired overall shielded
cables. If this cable does not solve your problem then signal conditioning equipment will
be needed to improve the signal.
VERIFYING VOLTAGE COMPATIBILITY
Different parts of the world use different standards for electricity. For example, most
areas of the United States use 115 volt electricity. Many other areas of the world use
220—240 volt electricity.
Verify the input voltage before plugging in your computer. The illustration of the back
panel earlier in this chapter shows the location of the input voltage switch.
If your computer is not set to the voltage you require, do not change the switch setting
without checking with your VAR first. Your VAR will insure that you have the proper
input voltage switch setting and power cord for your installation.
VERIFYING THE BOOT ID SWITCH SETTINGS (EAGLE 100-500 COMPUTERS ONLY)
The boot ID switches on the back panel of your computer are usually set for you at the
factory or by your VAR. The switch settings define what hard disk drive/backup device
combination your computer uses to boot from.
When you press the reset button, the computer reads the system initialization command
file and the system monitor to get itself up and running. You can select which device the
computer reads these files from by changing the boot ID switches. These four toggle
switches are accessible through a small opening in the back panel of your computer.
The word BOOT is silkscreened just below the opening where the four boot switches
reside.
The switches are numbered from top to bottom (1-4). Switches 1 and 2 are for the main
boot device; switches 3 and 4 select the alternate boot device.
The following diagram shows the various switch settings for both main and alternate
devices:
