Modem, RMI/TMI, and Switch Configuration MN/CRS300.IOM
5–2
5.2 Modem Configuration
5.2.1 Modem Power
Connect the power cords of each modem to a power supply and turn all modems ON.
5.2.2 Modem Firmware and Hardware Requirements
For the CRS-300 1:10 Redundancy Switch to operate correctly, it is important that all Traffic
Modems and the Redundant Modem must be of the same model. In addition to matching
hardware requirements, the Redundant Modem must have the same software revision and
installed options so that the it can properly mimic all Traffic Modems.
Permitted modem models and firmware versions are as follows:
Modem Modem Firmware Version

SLM5650/5650A Firmware and Hardware Requirements: In order to support the desired
redundancy, the appropriate firmware must be loaded in the SLM-5650/5650A base modem,
Network Processor (if applicable) and CRS-300. Higher versions of the firmware continue
support for the given interface (i.e. the highest version supports all interfaces); the lowest
firmware versions required to support a given interface type are shown in the following table:
