General Console Troubleshooting Procedures
-
To diagnose Console problems:
1. Load from boot tape. If the console loads OK, replace the hard
disk drive.
NOTE: Use a tape made from the “Create Boot Tape” function. To load
from tape, insert the boot tape and power up the console. Hold [HDWR
ALARM] throughout the Hardware Power Up Diagnostics screen until the
console indicates loading from the streaming tape. After the console
displays the Main Menu, enter [DISK DIRECTORY PEERWAY], cursor to
the “ TAPE” field, and press [ENTER]. Then perform the “Restore Tape
Files to Disk” function. Cycle DC power and try to load using the
Winchester disk. If the console still will not boot from the hard disk,
replace the disk drive assembly. For the Enhanced or Standard
Engineering Keyboard (1984--1654--000x): Hold the “H” key in place of
[HDWR ALARM].
2. If the console will not load from tape, replace the SCSI interface
card.
NOTE: Do not replace a SCSI Interface card with a Disk Interface card.
