4.2 Monitor LED Indication and Memory Backup Selection

After verifying proper operation of the power supply, turn your system ON to check the operation of
the monitor LED on the base board. The LED should flicker rapidly indicating the main processor is
functioning.
Now move the Memory Backup Selector to the ON position (Figure 2-5). Failure to do so may re-
sult in a loss of programming data and customer data in the event of a power failure.

4.3 PCB Verification

Before connecting all MDF cabling, plug in a test cable to the Champ connector on the base board
(Figure 2-3). Connect a display keyset and verify that it is working.
Use maintenance program MMC 727 (System Version Display) to verify the system version and
software version and to confirm the status of installed cards. If you are unsure about this, please
contact your dealer for advice.
Remove the test cable and plug in an amphenol-type cable and an RJ-45 cable to the MDF. Pro-
ceed with the rest of the installation.

4.4 Default Trunk and Station Numbering

When the system starts up, the CPU reads the expansion slot and the option connections for the
presence of a card and identifies its type. It stores this as the default configuration.
The system assigns trunk numbers beginning with 701. Station numbers begins with 201. The
keyset connected to the lowest port is assigned to the operator by default and all incoming trunk
calls ring the station until the default data is changed by programming.
Station and trunk numbers can be changed, rearranged and reassigned as needed using MMC
724 (Dial Numbering Plan).
