Chapter1 Cisco uBR7225VXR Overview
CiscouBR7225VXR Universal Broadband Router
•A midplane that serves as the interconnect between the cable interface line cards and the other
components of the system. See the “Subchassis and Midplane” section on page1-17.
•A fan tray, enclosing internal fans that draw cooling air into the chassis to maintain an acceptable
operating temperature. See the “Fan Trays” section on page 1-14.
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 cableinterface 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 uBR7200 series universal broadband routers supports:
•Environmental monitoring and reporting functions to resolve adverse environmental conditions
before loss of operation.
•Online insertion and removal (OIR), allowing key system components to be added or removed
without powering off the chassis.
Caution You can remove and replace a cableinterface 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 CiscouBR7225VXR router to
enable the interfaces on the new cable interface line card.
Caution The NPE does not support OIR. You must power down the chassis before removing the NPE.
