Handling Problems
If a problem arises, you must first make sure that all power and SCSI
cables are properly connected. Follow these steps to check the cables:
1. Turn off the terminal and all peripheral devices such as printers and
modems.
2. Turn off all expansion boxes.
3. Turn off the system unit.
4. Check that the following cables are correctly connected at both ends:
• Console cable (linking the local terminal to the system unit)
• Terminal power cord
• System power cord
• Expansion box connector cable to system unit
• Expansion box power cord
At this point all components should be off and any problem caused by badly
connected cables remedied. Now, set the on/off switches on your equipment
to 1 (on), in the order given in the following list.
1.
Turn on expansion boxes in the following order:
• RZ55 hard disk expansion box
• TK50Z tape expansion box
• RRD40 compact disc expansion box
2. Turn on the printer and modem, if you have this equipment.
3. Turn on the terminal.
4. Turn on the system unit.
The power-up test display should appear. If it does not, see Section 6.1,
