7 Powering on the Cisco uBR7225VXR Router
After installing your Cisco uBR7225VXR universal broadband router and connecting cables, check the following conditions
before powering on the router:
•Every component is securely inserted in the right slot and the captive installation screws are tightened.
•All network interface line cables are connected to the Ethernet ports on the NPE.
•Hybrid fiber-coaxial (HFC) network cable is connected to the cableinterface cards.
•A compact flash card is installed in a compact flash slot in the front panel of the NPE. Use only authorized, Cisco provided
compact flash cards.
•Each AC-input power cable is connected.
•The console terminal is connected.
Caution If a cable interface line card or the network processing engine is not properly seated or not fully locked into place,
the Cisco uBR7225VXR router might enter a continuous restart loop.
To power on the CiscouBR7225VXR router, complete the following steps:
Step1 Place the power switch on the power supply in the ON (|) position. Repeat this step if a second power supply is installed.
Two green LEDs on each power supply turn on indicating normal power supply functionality.
Step2 Listen for the fans; you should immediately hear them operating. In a very noisy environment, also look for air
movement around the chassis to verify that the fans are operating. If the Cisco uBR7225VXR router was recently
switched off, it might take up to 90 seconds for the power supply to restart and the fans to start operating.
Step3 Observe the initialization process. When the system boot is complete (a few seconds), the NPE begins to initialize the
cable interface line cards.
Note By default, Cisco uBR-MC16U or Cisco uBR-MC28U cable interface line cards have no output until the downstream
signal frequency is set and the no cab down rf-shut command is applied.
