Replacing a defective Base Station
To replace a Base Station, you do not have to power down the system. When
you replace a Base Station, no portable registration information is lost.
A Re-eval recommended message will be displayed. Your choices are to
perform System Reevaluation, schedule it for off-hours, or CLEAR
to disregard
the message. You need to perform System Reevaluation only if the Base
Station location changed in addition to replacing the defective Base Station.
If troubleshooting procedures (see “Troubleshooting a Base Station” on
page 169) indicate that one or both Base Station radios are defective, the Base
Station must be replaced as follows:
1. Disable the associated TCM devices using the Administration Terminal
software (see “TCM Status” on page 132).
