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.
| Model | PCI Bus 0 Total Bandwidth Points Used (Slots 1, 3, 5) | PCI Bus 1 Total Bandwidth Points Used (Slots 0, 2, 4) | Bandwidth Points Available for Modular Port Adapter |
