General System Problems Troubleshooting with the NeXTSTEP Operating System As has been described previously, you can diagnose hardware problems for the Epson NX system by inserting a DOS boot or diagnostics diskette and running the checks in this chapter. The paragraphs below describe a few features of the NeXTSTEP operating system that may be useful for a service technician to know during troubleshooting. 1 Like the UNIX operating system, NeXTSTEP needs to be powered down in an orderly manner. If you want to exit NeXTSTEP and power off the system: Hold down the right Alt key, press Num Lock, and then press h to halt the system. 2 If there is an abnormal system shut down, the NeXTSTEP operating system runs an extensive check of the hard disk drive to investigate the problem. The screen displays the message "Checking disks" for several minutes. After successfully running the system check, NeXTSTEP cleans the file system state (i.e., performs the procedure for an orderly shutdown), and then reboots. The system displays the message "Pile system clean" during initialization of the software. (In some instances of abnormal shutdown, the site system administrator (SUPERUSER) will be required to intervene and manually clean the file system.) 2-20 Epson NX Service Manual

Troubleshooting with the NeXTSTEP Operating System
As has been described previously, you can diagnose hardware problems for the Epson NX
system by inserting a DOS boot or diagnostics diskette and running the checks in this
chapter. The paragraphs below describe a few features of the NeXTSTEP operating system
that may be useful for a service technician to know during troubleshooting.
1
Like the UNIX operating system, NeXTSTEP needs to be powered down in an orderly
manner. If you want to exit NeXTSTEP and power off the system:
Hold down the right
Alt
key, press
Num
Lock,
and then press
h
to halt the system.
2
If there is an abnormal system shut down, the NeXTSTEP operating system runs an
extensive check of the hard disk drive to investigate the problem.
The screen displays
the message “Checking disks” for several minutes. After successfully running the
system check, NeXTSTEP cleans the file system state (i.e., performs the procedure for
an orderly shutdown), and then reboots. The system displays the message “Pile
system clean” during initialization of the software.
(In some instances of abnormal shutdown, the site system administrator
(SUPERUSER) will be required to intervene and manually clean the file system.)
