The 5466-1520 module is labeled as a P1020 CPU as part of the MicroNet Digital Controller series produced by Woodward Inc. out of Fort Collins Colorado. One key component of this module is the dual-core processor on the unit, this specific dual-core processor is 800 MHz. There are a number of ports on the module, which include, two Real-Time Network ports, one service port, five CAN ports, and four general-purpose Ethernet ports. In reference to the four Ethernet ports, there are two of each 100 Mbps and 1000 Mbps ports.
Typically CPU modules within the MicroNet series can be removed and inserted while the chassis is live and the 5466-1520 unit can also be removed or inserted live. An important thing to note prior to removing this module is that the module requires a reset, this notifies the module that it is going to be removed and that an effortless failover to the second CPU module will occur. There are several applications that this module will operate on such as Cyber Security and Graphical Application Programming (GAP) Applications.
As a MicroNet-Plus CPU the 5466-1520 module can be used with a redundant or simplex system, if the CPU is being used in a simplex system there will only be one CPU compared to if the CPU is being used in a redundant system there will be two CPUs no matter how many CPUs there are the initial CPU will be inserted into slot A1.
Prior to installation of the module refer to the three 26166 manuals, specific information regarding the standards of the 5466-1520 module can be found on pages 174-175 of the 26166V2 manual.
