Increasingly, business applications and services affect aggregation requirements and router-integrated services across the WAN and metropolitan-area network (MAN)-in both the branch and headquarters. Consequently, to continue to meet the increasing needs of flexibility, capacity, and performance and maintain exceptional value and flexibility, Cisco Systems introduces the Cisco 7200VXR Series Port Adapter Jacket Card. The jacket card addresses the demand for additional slot density and flexibility by enabling the I/O slot to hold a single port adapter for additional capacity on systems with the Cisco 7200VXR Series NPE-G1 Network Processing Engine and above.
