downstream (DS) port.  
2 Feature Description  
QUICK START GUIDE  
The RF downstream port rings and end  
tabs are green for uBR-MC16U (see  
Figure 2) and slate blue for uBR-E-16U.  
The Cisco uBR-MC16 cable interface line card  
improves RF performance, supports spectrum  
management, increases system performance and  
supports online insertion and removal (OIR).  
The line card is available in three configurations:  
Step 2 Connect the upstream cables to the

Cabling the Cisco uBR-MC16X  
The Cisco uBR-MC16X cable interface line card  
(not supported on Cisco uBR7225VXR) does not  
have an onboard upconverter. The card may  
require up to 10-dB of attenuation due to a higher  
IF output power (higher than legacy Cisco cable  
interface line cards). To cable the card:

The IF downstream port ring and end tabs  
are yellow. See Figure 3.  
If you are using the Cisco uBR-MC16 line card  
to replace a different type of card, you must  
reconfigure the MC16U/X/E card.  
Step 2 Add RF attenuators as required to get the  
correct IF output. Insert the attenuator  
between the downstream IF output cable  
and the upconverter. See Figure 3.  
Note  
The cable interface line card insertion and  
removal method is the same for all the  
Cisco uBR7200 series routers.  
We recommend that you reload a Cisco 7200  
series router when replacing a cable interface  
line card with a card of a different type.  
Step 3 Connect the upstream cables to the  
upstream ports on the card (US0—US5).
