than those previously listed indicates an error is most likely on the compact
disc or its controller module, but never rule out the possibility of an error on
the SCSI controller itself.
2.19 TEST 5 - SYS - Interrupt Controller and
Ethernet ID ROM
The interrupt controller manages the device interrupts in the system and
the Ethernet ID ROM is checked for valid contents. The SYS code shows
0000.0100 if the keyboard is disconnected from the system box.
Self-test is used to troubleshoot the SYS circuits. The system exerciser does
not test the SYS circuits. Enter TEST S to run self-test. Enter TEST 50 to
see the results.
A code of 0000.0001 next to the SYS mnemonic indicates no errors detected
with the SYS circuits. Replace the system module if any other code is listed
(except 0000.0100 as previously described and 0000.0004 as described in the
following section).
2.19.1 Addltlonal SYS Information
A code of 0000.0004 next to the SYS mnemonic indicates an error in the
Ethernet ID ROM. Since the ROM is not an FRU, you most replace the
system module but do not swap the Ethernet ID ROM as instructed to when
replacing the system module. Leave the ROM on the new system module
in this case. Notify the system manager of the new Ethernet ROM since the
Ethernet address for the system is now different.
Appendix B contains the power-up and self-test error codes.
2.20 TEST 4 - 8PLN - 8-Plane Graphics Module
The 8-plane graphics module contains the video circuits and memory for color
graphics on a color monitor or shades of gray on a monochrome monitor.
Self-test and the system exerciser are used to troubleshoot the graphics module.
Enter TEST 4 to run self-test. Enter TEST SO to see the results or enter TEST
80000106 and 4 at the prompt to run the system exerciser on just the 8-plane
graphics module circuits.
A code of 0000.0001 (self-test) next to the 8PLN mnemonic indicates no errors
detected with the graphics module. Refer to Section 2.20.1. l if any other code
is listed.
