Figure 1-5 PA-A6-T3—Faceplate View

The PA-A6 can be installed on the Cisco 7200 series routers, Cisco 7200 VXR routers, Cisco 7201

router, Cisco 7301 router, Cisco 7304 PCI Port Adapter Carrier Card in the Cisco 7304 router,

Cisco 7401ASR router, Cisco 7500 series routers using VIP4-50 and VIP4-80, and Cisco 7600 series

routers using FlexWAN modules. There are no restrictions on slot locations or sequence; you can install

a PA-A6 in any available port adapter slot.
