Using Tests
The system uses two types of tests to check system hardware
operation:
Power-up self-tests, which run a comprehensive test of the
system hardware
Subtests, which run individual tests or test scripts
If you run a test script, you can select one of several prepared
scripts or create your own.
Using Slot Numbers in Test Commands and Error Messages
Test commands and error messages include slot numbers that
identify the hardware to which the test command or error
message refers.
Slot number 3 always refers to the base system hardware,
which includes the following:
System module
CPU module
Memory modules
Base system Ethernet controller
Base system SCSI controller
Serial line controllers
Slot number 2 refers to the TURBOchannel option slot
nearest the power supply.
Slot number 1 refers to the middle TURBOchannel option
slot.
Slot number 0 refers to the TURBOchannel option slot
farthest from the power supply.
Figure 3-1 shows the slot numbers for the base system and the
option modules.
