Troubleshooting CRX and HCRX Graphics
If the workstation has one of the CRX or HCRX graphics options installed, and there
is no output on the monitor, use the following procedure to troubleshoot the problem:
1.
Power off the workstation and the monitor.
2.
Make sure that all connectors and cables are fully seated and that the monitor is
connected to the correct connector for the CRX or HCRX graphics option. See
Chapter 1 of this manual for monitor connections.
3.
Power on the monitor and the workstation.
If, after a few minutes, there is still no output on the monitor, continue to
Step 4.
4.
Power off the workstation and the monitor.
5.
Disconnect the monitor and connect it to the built–in graphics connector as
shown in Chapter 1 of this manual.
6.
If the workstation is a Model 715/C, 715/33, 715/50, or 715/75, check the
workstation’s graphics configuration switches, as shown in Chapter 3 of this
manual, to ensure that the graphics switches are set correctly for the monitor.
7.
Power on the monitor and the workstation. Observe the LED codes as they are
displayed on the front of the system unit.
8.
After the self tests have begun, when LED indicators number 8 and 4 are lit
(and all other amber LEDs are off), press the TOC switch on the front of the
system unit. (See Chapter 1 of this manual for the TOC switch location.) This
LED pattern indicates that the system is checking the CRX or HCRX graphics
for errors. See Figure 4–2.
