Stinger® FS/Stinger FS+ Getting Started Guide
Configuring Control Modules and System Timing
Configuring control module redundancy
The following example shows how to change this setting on the primary control
module, so that a Y-cable can be connected to both control modules:
admin>
read serial {1 first-control-module 2}
SERIAL/{ shelf-1 first-control-module 2 }
admin>
set console-mode = y-cable
admin>
write

Remote modem administration of redundant control modules
You can also create a bridged connection to the modems of control modules that are
equipped with internal modems. A telephone line can be bridged to both modems so
that dial-in administrative access to the primary control module takes place through
one telephone line.
To do so, you can either connect a two-wire line to the RJ-11 connector of the
modem port on each control module and then bridge the lines at a connector block,
or use an RJ-11 bridge adapter. Several types of adapters are available for bridging
RJ-11 connections. One example is shown in Figure 5-9.
