The I/O controller, port adapters, Port Adapter Jacket Card, power supplies, and network processing
engine or network services engine slide into their respective chassis slots and connect directly to the
routers midplane; there are no internal cables to connect. The midplane distributes power from the power
supplies to the I/O controller, port adapters, Port Adapter Jacket Card, fan tray, and network processing
engine or network services engine.
The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to
packet memory on the network processing engine or network services engine, arbitrates traffic across
the PCI buses, and generates the clock signals for the port adapters on each PCI bus.
The Port Adapter Jacket Card does not support OIR. However, the port adapter installed in the Port
Note
Adapter Jacket Card does support OIR.
The Cisco 7204VXR operates as either a tabletop or a rack-mounted unit. A rack-mount kit is standard
