Cisco 3270 Rugged Router Card
This chapter describes the features of the Cisco 3270 Rugged Router card. The Cisco 3270 Rugged
Router card is the core component of a Cisco 3270 Mobile Access Router. It is compatible with other
Cisco 3200 Series router mobile interface cards (MICs), such as the Wireless Mobile Interface Card
(WMIC). The Cisco 3270 Rugged Router card is also available as a standalone router card (to be
embedded into a third-party enclosure).
The Cisco 3270 Rugged Router card includes the host processor, memory, ports, and LED signals.
Additional components provide power and link interfaces; for example, the Serial Mobile Interface Card
(SMIC) provides the serial interfaces. The exact configuration of your router will vary, depending on
how the device was configured by the vendor.
The Cisco 3270 Rugged Router card has the following features:
• Support for the PC/104-Plus form factor.
• Dual 32-bit PCI buses, one running at 66 MHz and the other at 25 MHz.
• 256-MB, 64-bit, unbuffered, double data rate (DDR), synchronous DRAM.
• 64-MB, 16-bit flash memory.
• Two Fast Ethernet ports with autonegotiation.
• Two Gigabit Ethernet port signal sets with autonegotiation; the router can be ordered with support
for one fiber-optic port and one copper port, or with two copper ports.
• Console port signals, with modem flow control.
• Asynchronous EIA/ITA 232 serial port signals with 5V auxiliary power for GPS/AUX devices.
• Two USB 2.0 high-speed (480-Mbps) port signal sets.
• High-performance hardware encryption processor.
• Zeroization to clear up any trace of user data or binary code.
• Industrial-grade components that support local component ambient temperature ranges.1
• An enhanced PCI-to-PCI bridge that supports asynchronous operation. The asynchronous bridge
allows each port to run from a separate independent clock for the highest performance. A
synchronous clock forces one side of the bridge to slow down to support a slow device on the other
side of the bridge; asynchronous bridge clock domains can be arbitrarily different.

+85°C device temperature as opposed to local component ambient temperature.
