RTN Expansion Chassis Configurations
The MicroNet TMR5200 can expand from a single main rack to a maximum 4-rack system by using Remote
RTN modules and copper or fiber optic Ethernet switches. A maximum of 3 MicroNet Plus expansion racks (14
slot or 8 slot versions) or MicroNet Simplex racks (6 or 12 slot versions) are supported. If desired, fiber optic
Ethernet switches can be used to locate each chassis in a different location. It is required to use Woodward
approved Ethernet hardware for robust operation.
Ethernet Switch Hardware
For systems with more than a single RTN module, copper or fiber optic Ethernet switches are required to
achieve communication and hardware redundancy. Specific Ethernet switches have been tested and
approved to obtain expansion chassis real time performance and redundancy.
Due to the critical nature of communications with an RTN expansion rack, it is required to use Woodward
approved copper and fiber Ethernet switches for robust system operation. At the time of this writing, the
following hardware part numbers are approved.
For redundant operation, the control can use any combination of power supplies.
The power supplies can only be installed into slots PS1 (power supply #1) and PS2 (power supply #2). If
redundant power supplies are not needed, blanking plates must be installed in the slots not being used.
Branch circuit fuses, circuit breakers, and wiring must meet appropriate codes and authorities having
jurisdiction for the specific country (CE, UL, etc.). See Table 4-3 for maximum recommended fuse or
breaker ratings. Do not connect more than one main power supply to any one fuse or circuit breaker. Use
only the wire sizes specified in Table 4-3. which meet local code requirements. Time delay fuses or circuit
breakers must be used to prevent nuisance trips.
In the event that on supply needs to be replaced, the recommended method for changing
Power Modules is with the power off (to the module being removed and the module being inserted).
The system will tolerate this “cold swap” method without failure.
