Power-up diagnostic routines consist of the complete set of diagnostics for the system. When
enabled, they are executed upon system power-up and may last several minutes. These
diagnostics will perform a rigorous check on the response and performance of the hardware
and firmware. Any failures will be displayed on the LED display and the RS-232 terminal (when
requested), and logged in a file on the NVRAM.
The background diagnostic routines consist of the complete routines which are run during
system operation. When enabled they are executed as low priority background routines during
system operation.
Directed diagnostics are diagnostic routines that are selected by the maintenance person and
then run on specified circuits or devices.
Upon power-up or reset conditions, the diagnostics software (if enabled) has temporary control
of the entire system. Once the system has been verified and is operational, the diagnostics run
as low priority background tasks.
Modular design and functional packaging of the equipment permits rapid location and
replacement of defective components. Circuit malfunctions are detected by diagnostic routines
automatically initiated by the Main Control Card. Diagnostic routines direct service personnel
to the defective circuit card or assembly, and identify the required field-replaceable unit.
Diagnostic routines and maintenance procedures do not interfere with users unaffected by the
malfunction.
Remote Maintenance Administration and Test (RMATS) Access
RMATS allows personnel at a central maintenance center to access the SX-200 EL or SX-200
ML system and retrieve maintenance data or make programming changes.
Remote Printing of CDE Reports
CDE reports are generated and captured on the remote terminal so the user can obtain a
softcopy of the reports and print them. CDE Form 32, CDE Data Print, has two new softkeys:
DISPLAY and DISPLAY ALL. These softkeys are equivalent to the PRINT and PRINT ALL
softkeys; causing the selected print option to be executed but with the data reflected back to
the terminal. The softkeys are dependant on System Option 102, Feature Level 2 or greater.
Remote Software Download
Remote software download allows a system software upgrade to be performed from a PC
connected to a system. System software to be loaded onto the maintenance PC can be obtained
by subscribing to the Mitel Networks subscription service. At the system, System Option 109 -
Remote Software Download must have been purchased and enabled. The PCMCIA Memory
Card on the Main Control Card must be the four megabyte variant for this option.
