SETUP GUIDE
WARNING
DO NOT MIX MODEM TYPES IN THE SWITCH.
For the CRS-200 to operate correctly, identical modem types must be used for all traffic modems, and the
redundant modem. As an example, it is not permissible to have a mixture of CDM-500 and CDM550T
modems within the same redundancy switch group.
IMPORTANT NOTE
For correct operation of the CRS-200, the Modems must have the following Firmware versions installed:
CDM-500 - Version 1.18 or later
CDM-550 - Version 1.15 or later
CDM-550T - Version 1.10 or later
If the modems do not meet this requirement, please contact the factory to arrange for a free upgrade to be
sent to you.
Once the switch and all the modems have been mounted, the user must properly attach all
required cabling and configure the system for correct operation. What follows is a step by
step description of this process. Please leave the switch and all modems powered off until
all connections are ready.
