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:

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:

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
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).
