Hardware setup for a Model 2707RC
The following must be done to configure your Model 2707RC hardware for use with the Model 1001MC net-
work management station:
• Connect frame ground to signal ground (see section “Configuring frame ground”)
When you are finished, install the Model 2707RC front card and rear I/O card using the installation proce-
dures in the manual that came with the modem.
Configuring frame ground
The Model 1001MC uses an internal bus to communicate with the NetLink modems installed in your system.
The Model 2707RC 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 installation
manual that came with the rack card for more information on this jumper setting.
