4.2.1 Modem Power
Connect the power cords of each modem to a power supply and turn both modems ON.
4.2.2 Modem Firmware and Hardware Requirements
For the CRS‐311 to operate correctly when configured for use with the CDM‐Qx/QxL
or SLM‐5650/5650A modems, the Traffic Modem and the Redundant Modem must
be of the same model having identical hardware configurations, equipped with the
same option modules – all with the same firmware versions. This is mandatory for
the Redundant Modem to properly mimic operation of the Traffic Modem upon
switchover.
CDM‐Qx/QxL Firmware and Hardware Requirements: For proper redundant operation,
regardless of data interface, CDM‐Qx/QxL Firmware Version 1.1.4 or later must be used.
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‐311. 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 as follows:

4.2.2.1 Flash Upgrading
For detailed instructions on upgrading modem firmware via flash upgrade, See the pertinent
modem’s Installation and Operation Manual.
4.2.3 Modem Operational Configuration
This chapter assumes user familiarity with the individual modems’ front panel menu navigation,
and their configuration parameter selection methods. For detailed instructions on changing
configuration settings using the front panel keypad and menus, see the Front Panel Operation
chapter in the pertinent modem’s Installation and Operation Manual.
