The Cisco® PIX® 64-Bit/66-MHz 4-Port Fast Ethernet Interface Card delivers a high-performance PCI interface, increased port density per PCI slot, and easy integration with the market-leading Cisco PIX Security Appliance Series. For small to medium-sized business, large enterprise, and service provider networks, the Cisco PIX Security Appliance Series offers extensible solutions that provide robust, enterprise-class, integrated network security services with solid investment protection. This 4-port Fast Ethernet card takes full advantage of this extensibility, enabling enterprises to segment their networks and provide a wide-range of high-performance security services including stateful inspection firewalling, advanced application and protocol inspection, VPN, inline intrusion protection, and rich multimedia and voice security services in an easy-to-deploy solution. Native High-Performance Bus Interface Drives Scalable Security Services The Cisco PIX 64-Bit/66-MHz 4-Port Fast Ethernet Interface Card natively supports high-bandwidth 64-bit/66-MHz PCI bus interfaces, including those found in Cisco PIX 535 Security Appliances, enabling enterprises to deliver high-performance security services for rapidly evolving network environments that require Fast Ethernet connectivity. By providing compatibility with 32-bit/33-MHz PCI bus interfaces, this interface card can also be deployed within other modular models of the Cisco PIX Security Appliance Series. Part of the family of high-performance, 64-bit/66-MHz PCI-enabled cards for the Cisco PIX Security Appliance Series, including the Cisco PIX VPN Acceleration Card Plus (VAC+) and the Cisco PIX Gigabit Ethernet Interface Card, the Cisco PIX 4-Port Fast Ethernet Interface Card allows enterprises to take full advantage of the high-performance architecture of Cisco PIX 535 Security Appliances, and deliver highly scalable security services for the most demanding enterprise environments. Multiple Network Interfaces Facilitate Enhanced Network Security The Cisco PIX 64-Bit/66-MHz 4-Port Fast Ethernet Interface Card enables enterprises to physically separate/segment network traffic for improved security. Increased network segmentation allows enterprises to create separate security "zones," each with its own set of security policies. These zones can range from the Internet, internal corporate departments/sites, to network segments sometimes referred to as demilitarized zones (DMZs) which provide shared network services between two or more other zones. Multiple interfaces on a single card conserve valuable PCI slot space and maximize throughput per slot. Plugging multiple cards into extensible Cisco PIX Security Appliances achieves overall higher port density and scales as customer requirements grow. Standards-Based Solution Lowers Total Cost of Ownership The Cisco PIX 64-Bit/66-MHz 4-Port Fast Ethernet Interface Card conforms to Ethernet and Fast Ethernet standards. The card is automatically detected when installed in Cisco PIX Security Appliances, minimizing operating expenses while maximizing the return on networking investment.
