Installing NetLink modem cards 24Model 1001MC Operations Guide 2 • Hardware installationHardware setup for a Model 1095RCThe following must be done to configure your Model 1095RC hardware for use with the Model 1001MC net-work management station:• Connect frame ground to signal ground (see section “Configuring frame ground”)• Set the system address (see section “Setting the 1094ARC system address”)When you are finished, install the Model 1095RC front card and rear I/O card using the installation proce-dures in the manual that came with the modem.Configuring frame groundThe Model 1001MC uses an internal bus to communicate with the NetLink modems installed in your system.The Model 1095RC rear I/O card must have frame ground (GND) connected to signal GND through a 100-ohm resistor. This is done by configuring a jumper on the modem’s rear I/O card. Refer to the installationmanual that came with the rack card for more information on this jumper setting.Setting the 1095RC system addressThe manual that was shipped with the 1095RC defines switch S1 as Address. This switch sets the address ofthe modem in the NetLink system. Each card in the chassis is given a unique address through the setting ofswitch S1.Note Standalone units use the address of the rack card that they are con-nected to.Polling overview. The Model 1001MC sends poll messages along the internal bus looking for cards installedin the system. Once a card is found it is placed online and communication with the management station canbegin.If the address of the NetLink modem is not configured or does not match the address range of the rack that itis installed in, the Model 1001MC may not recognize the card. The address range that is polled is determinedby the configuration of the system. The system administrator must make sure that the software configurationwithin the Model 1001MC matches the hardware configuration of the system.Polling rack #1 and daisy-chained racks. The Model 1001MC uses the number of power supplies in the sys-tem to determine what the address range of the individual racks will be. The number of power suppliesinstalled in each rack is entered on the Modem Information page. If the system is set for two power suppliesinstalled, the 1001MC will automatically set the number of slots available (displayed on the Modem Informa-tion page) in the chassis to 13. If the system is set for a single power supply installed, the 1001MC will auto-matically set the number of slots available in the chassis to 15.Table 6.
