Cisco C7200-JC-PA interface cards/adapter

7200 VXR Series Port Adapter Jacket Card, Spare 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. Benefits of the jacket card include the following (refer to Table 1 for details):
-Provides one additional slot for single port adapter (selected port adapter).
-Allows a high-bandwidth port adapter-such as the hardware based security encryption module SA-VAM2+ and the 2-Port Packet/SONET OC3c/STM1 Port Adapter-to be moved onto a dedicated Peripheral Component Interconnect (PCI) bus that the Cisco NPE-G1 or NPE-G2 provides.
-Reduces PCI contention among other port adapters.
-Provides a cost-effective way to increase the slot density in parallel to the increased switching capacity of the newest engine of the platform-the Cisco NPE-G2.
