Setting the address range for your NetLink modems
The Model 1001MC polls the system looking for NetLink modems. If the address of the NetLink modem is
not configured or does not match the rack that it is installed in, the Model 1001MC may not find the card.
The address range that is polled is determined by the configuration of the system. The system administrator
must make sure that the software configuration within the Model 1001MC matches the hardware configura-
tion of the system.
The Model 1001MC uses the number of power supplies in the system to determine what the address range of
the individual racks will be. The number of power supplies installed in each rack is entered on the Modem
Information page. If the system is set for two power supplies installed, the 1001MC will automatically set the
number of slots available (displayed on the Modem Information page) in the chassis to 13. If the system is set
for a single power supply installed, the 1001MC will automatically set the number of slots available in the
chassis to 15.
Using this information, the Model 1001MC will poll the specified address range in each rack. Thus, in a single
power supply system, the address range for rack #1 (the rack with the 1001MC installed) will be from address
1 to address 15
Note The 1001MC is always address 0.
