Chapter 1 Overview
Field-Replaceable Units
Port Adapters
The port adapters installed in Cisco 7100 series VPN routers are of the same type as those installed in
the Cisco 72xx family routers. For information on supported port adapters, refer to the Cisco Product
Catalog or contact your local sales representative. The port adapters provide network interfaces to
connect the router to external networks.
For a complete list of port adapters available to the Cisco 7100 series VPN routers, see the Cisco 7100
Series VPN Router Documentation—DOC-7814391=

All port adapters available for the Cisco 7100 series connect directly to the router and are locked into
position by a locking tab with two screws (see Figure 1-26). To remove or replace a port adapter, you
must loosen the screws (using a number 2 Phillips screwdriver) and slide the tab down. To lock the port
adapter in place, slide the tab up and tighten the screws.
Note Detailed port adapter installation information is contained in the installation note for the port adapter.
For example, if you plan to replace a four-port Ethernet port adapter in your Cisco 7100 series VPN
router, refer to the PA-4E Ethernet 10BaseT Port Adapter Installation and Configuration note. The
document is available online and on the Documentation CD-ROM.

Caution To ensure adequate airflow across the router port adapters, a port adapter or a blank port adapter must
be installed in each port adapter slot. The product number for the blank port adapter is
MAS-7100-PABLANK=.
Integrated Service Module (ISM)/Integrated Service Adapter (ISA)
The ISM/ISA is a Layer 3 encryption module that supports IP Security Protocol (IPSec) encryption of
IP datagrams. In addition to enabling the secure use of public switched networks and the Internet through
encryption, the ISM/ISA supports all encryption features supported by the Cisco IOS software. The
hardware-based services provided by the ISM/ISA improve the overall performance of Cisco 7100 series
routers by off-loading data encryption processing from the main system processor.
For more information on ISM or ISA features and for installation and configuration information, refer
to the Integrated Service Adapter and Integrated Service Module Installation and Configuration online.
