The ISA buses and PCI buses on the Cisco 3200 Series Mobile Access Router cards provide power to
the components on the cards. Both buses comply with the PC/104-Plus standard. The ISA bus allows
PC/104-Plus ISA signals to pass through the card bus, but the Cisco cards do not use any of the signals.
The PCI bus signals allow the Cisco cards to communicate. Non-Cisco cards cannot communicate with
the Cisco
3200 Series Mobile Access Router cards over the PCI bus.
Caution If you add non-Cisco cards that generate signals on the PCI bus, the router might shut down. Do not add
non-Cisco cards that generate signals on the PCI bus.
