Maintenance and Troubleshooting
Considerations
Review the following points before you begin remote maintenance procedures.
Remote maintenance overrides onsite maintenance and programming, except when onsite
I
backup or restore is in progress. Before you perform remote maintenance, notify the
customer's system manager.
You can perform remote maintenance and programming only from a DOS PC, not from the
I
UNIX environment. If you are running SPM under IS III, you cannot perform remote
maintenance.
Line noise can cause the SPM screen to display unpredictable results. If this occurs, hang up
I
and redial.
Under applicable tariffs, the customer is responsible for any charges incurred through the
I
remote use of system facilities. Precautions should be taken to prevent unauthorized use of
the system's outside lines by remote callers, also called toll fraud. See Appendix A, "Customer
Support Information," for more information about security.

Preparation for Hardware Maintenance

If you are performing onsite hardware maintenance where you need to access hardware inside the
carrier, for example remove a module, you must first remove the control unit housing, power down
the system, and then disconnect AC power.
See "Installing/Removing the Cover on the Carrier" in Installation.

I
Powering Down the System
To power down the system, follow these steps:
CAUTION:
Follow these steps in the exact sequence.
1. Turn off the power supply on the basic carrier.
2. Turn off the power supplies on the expansion carriers.
3. Unplug the system from the AC outlet.

Using WinSPM

To perform remote maintenance procedures, you must use a PC with Windows System
Programming and Maintenance (WinSPM) software. For information on setting up and using
WinSPM, see Programming Basics.
