The cable interface cards, NPE, and power supplies slide into their respective chassis slots and connect
directly to the router midplane. There are no internal cables to connect. The midplane distributes power
from the power supplies to the cable interface cards, fan tray, and NPE.
The Cisco uBR7225VXR universal broadband router may be installed on a tabletop or rack-mounted. A
rack-mount kit ships with each router. The rack-mount kit includes the hardware needed to mount the
router in a standard 19-inch equipment rack or telco-type rack.
The Cisco uBR7225VXR universal broadband router supports:
Environmental monitoring and reporting functions to resolve adverse environmental conditions

Online insertion and removal (OIR), allowing key system components to be added or removed
•
without powering off the chassis.
You can remove and replace a cable interface line card with the same type of component without

interrupting the rest of the system or having to reconfigure the system. However, to replace a
cable interface line card with a different type of card (for example, hot swapping from a
Cisco uBR-MC16U cable interface line card to a Cisco uBR-MC28U cable interface line card), you must
copy your startup configuration to your running configuration on the Cisco uBR7225VXR router to
enable the interfaces on the new cable interface line card.
The NPE does not support OIR. You must power down the chassis before removing the NPE.
