Switch S1-8: Loopback tests
Use switch S1-8 to allow the Model 2707RC to enter loopbact test mode
when the DTE raises the appropriate loop request pin.
Switch S3: DIP switch or NMS (network management system) control
The Model 2707RC can be configured and managed via DIP switches, or
NMS-SNMP/HTTP through a Patton Model 1001MC management card
acting as a proxy agent. (refer to the 1001MC user manual when using
this mode). Switch S3 selects control and management mode for the
Model 2707RC.
Hardware Reset .
The Model 2707RC is set at the factory for DIP switch
control. If the user has changed control to NMS, and then needs to revert
to DIP switch control, use the following procedure:
1. Pull the Model 2707RC out of the rack.
2. Set all switches (S1 and S3) to the ON position.
3. Install the card into the rack and power up the unit.
4. Pull the card out again and change the switches to the desired set-
tings. The unit is now under DIP switch control.
5. Install the card back into the rack.
NMS Control.
When switches S3-1 to S3-8 are set to a setting other
than the ones shown in Table 6, the Model 2707RC enters NMS control.
While under NMS control, each of the Model 2707RC cards housed in a
rack must have an address. Table 7 and Figure 3 show examples of
address settings. The table follows the hexadecimal system, where
switch SW3-1 is the least significant bit (LSB), and SW3-8 is the most
