Chapter 2 Cisco 3270 Rugged Router Card Cisco 3270 Rugged Router Card Power Requirements The Cisco 3270 Rugged Router card uses +3.3 V, +5 V, and +12 V power sources. Typical power consumption is 20 W. The maximum calculated wattage is 26.5 W. Table 2-1 Cisco 3270 Rugged Router Card Voltages Voltage +3.3 V +5.0 V +12.0 V Current 1.8 A 4.0 A 0.05 A Power 5.9 W 20.0 W 0.6 W Power Connections (AUX) The speed of the AUX port for the Cisco 3270 Rugged Router card can be configured as 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, or 460800 bps. Use the line aux linenumber speed command to modify the speed of the port. A +5V power supply is provided for devices connected to the AUX port. A Global Positioning System (GPS) modem is used as an example in this section. Typically the +5V power supply current to GPS modems should be limited to less than 200 mA. Table 2-2 shows the pin assignments for power on the AUX port.

The security engine contains four crypto channels, a controller, and a set of crypto execution units (EUs). The SEC can act as a master on the internal bus. This allows the SEC to alleviate the data movement bottleneck normally associated with slave-only cores. The host processor accesses the SEC through its device drivers, using system memory for data storage. The SEC resides in the peripheral memory map of the processor; therefore, when an application requires cryptographic functions, it creates descriptors for the SEC that define the cryptographic function to be performed and the location of the data. The SEC bus-mastering capability permits the host processor to set up a crypto channel with a few short register writes, leaving the SEC to perform reads and writes on system memory to complete the required task.
