APPENDIX A
Modular Port Adapter Configuration Guidelines
The maximum recommended bandwidth points on each Peripheral Component Interconnect (PCI) bus
is 600 points. For best performance we recommend that you avoid using port adapters that exceed the
total available bandwidth for your router.
Table A-1 shows the modular port adapter bandwidth points available for each model and Table A-2 lists
the port adapter bandwidth points.
Note For the Cisco 7140-2MM3, we recommend that you use port ATM 1/0 as your primary interface and port
ATM 2/0 as your backup interface.
