During repair and maintenance procedures:
•
Insert circuit cards into compatible slots only.

Turn off the circuit breaker or switch for a cabinet power supply before
the power supply is removed or inserted.
•
Software disable circuit cards, if applicable, before they are removed or
inserted.
•
Hardware disable circuit cards, whenever there is an enable/disable
switch, before they are removed or inserted.
•
Return defective circuit cards to a repair center; do not try to repair or

Communicating with the system
You can exchange information with the system through the system terminals
and the maintenance telephone. This section discusses these tools for
communicating with the system.
System terminal
You can send maintenance commands and receive system messages by
accessing the system through an RS-232 device, such as a video display
terminal (VDT) or teletypewriter (TTY).
Software format
Through the system terminal, you can enter commands that tell the system to
perform specific tasks; the system performs the tasks and sends messages
back to the system terminal, indicating status or errors. System messages,
along with indicators such as light emitting diode (LED) indicators, identify
faults in the system.
