Cisco 3200 Series Rugged Enclosures

Customers can work with system integrators on enclosure solutions or they can choose a rugged enclosure from Cisco. Cisco provides rugged enclosures for the Cisco 3230 and Cisco 3270 models that address mobility needs for the public safety, transportation, and defense markets. Manufactured by Cisco, this rugged, sealed enclosure is designed for use in vehicles, trains, or airplanes. The rugged enclosure is designed and tested to withstand extended temperatures, high altitude, shock, vibration, and exposure to damp, wet, or dusty environments. The Cisco 3200 Rugged Enclosures provide:

• A rugged design meeting a wide range of environmental specifications, including MIL-STD-810F, MIL-STD-461E, NEMA 4, and SAE (J1211 and J1455) standards

• A sealed enclosure that uses conductive cooling without the use of internal fans

• A modular enclosure that offers expansion slots for future growth

Mobile Networks

The Cisco 3230 Rugged ISR offers a wireless, ruggedized, high-performance router designed to extend the IP network from wired premises out to moving infrastructure, including vehicles, trains, planes, and ships. The Cisco 3230 Rugged ISR creates a mobile network to establish a highly secure IP network for remote devices in a moving or stationary vehicle. Remote users can exchange voice, video, and data communications with a central site and securely access resources in real time. The Cisco 3230 forms a wireless network in and around a mobile network to allow users to roam while still maintaining a highly secure broadband connection.
To address the need for always-on, mobile access for mission-critical applications, the Cisco 3230 Rugged ISR uses standards-based Mobile IP features in Cisco IOS Software to allow the mobile node or network to stay connected as it moves from one wireless network to another. Transition to different wireless networks is transparent to the users and devices (such as laptops, personal digital assistants [PDAs], and surveillance cameras), and applications maintain continuous connectivity without the user having to manually intervene as WAN links change. In addition to allowing a single node or device to stay connected, the Cisco 3230 Rugged ISR allows an entire mobile network or subnet to stay connected.

Embedded Outdoor Networks

Utility and energy companies are discovering the benefits of bridging proprietary networks with IP networks. The challenge arises when these proprietary networks are located in remote sites, without temperature-controlled environments. With industrial-grade components, the Cisco 3230 Rugged ISR is an ideal platform for connecting these disparate networks to an IP network. The Cisco 3230 Rugged ISR provides standard Ethernet, serial, and wireless interfaces used to connect isolated networks or devices such as utility substations, traffic signal controllers, and video cameras to an IP network.

Network Security, Reliability, and Manageability

Cisco 3230 Rugged ISRs run Cisco IOS Software which provide capabilities for network security, manageability, and scalability. Cisco IOS Software offers integrated network security features, including authorization and authentication, stateful firewall, intrusion detection, and Triple Digital Encryption Standard (3DES) or Advanced Encryption Standard (AES) encryption for VPNs. Remote management capabilities give network managers visibility into and control over the remote network, including devices connected to the router. Powerful debug and troubleshooting commands allow network managers to quickly isolate network problems and securely make changes to network configurations.
