Cisco Systems uBR-MC16U-X, uBR-E-16U User Manual
QUICK START GUIDE
Installing Cisco uBR-MC16U/X
and uBR-E-16U
Cable Interface Line Cards
1 Purpose
This quick start guide shows you how to install a
Cisco uBR-MC16 cable interface line card in the
Cisco uBR7200 series router.
2 Feature Description
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:
• Cisco uBR-MC16U—With an onboard
upconverter and green end tabs
• Cisco uBR-E-16U—With an onboard
upconverter and slate blue end tabs
• Cisco uBR-MC16X—Without an onboard
upconverter and yellow end tabs
3 Prerequisites
Step 3 With the metal carrier aligned in the slot
guides (see Figure 1), briskly slide the card
into the card slot until you feel it seat in
the backplane connectors.
Step 4 Tighten the captive screws.
Note The captive screws provide grounding for
the electromagnetic interference (EMI)
shielding.
Figure 1 Installing the Card in the Chassis
Cabling the Cisco uBR-MC16U/E-16U
The Cisco uBR-MC16U/E-16U cable interface line
card has an onboard upconverter. To cable the
card:
Step 1 Connect the downstream cable to the
downstream (DS) port.
The RF downstream port rings and end
tabs are green for uBR-MC16U (see
Figure 2) and slate blue for uBR-E-16U.
Step 2 Connect the upstream cables to the
upstream ports (US0—US5).
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:

Warning
Only trained and qualified
personnel should be allowed to
install, replace, or service this
product.
Caution You must be properly grounded
before handling this
ESD-sensitive product.
• The Cisco NPE-400 or the Cisco NPE-G1 or
the Cisco NPE-G2 network processing engine
must be used with this 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.
• We recommend that you reload a Cisco 7200
series router when replacing a cable interface
line card with a card of a different type.
4 Installing the Card
Note The uBR-E-16U line card is an entry-level
version of the uBR-MC16U line card, and
fits only in the uBR7225VXR chassis.
Step 1 Make sure that you are grounded.
Step 2 Use both hands to grasp the line card by its
metal carrier edges and align the line card
with the slot guides, component side up.

Step 1 Connect the downstream cable to the
downstream (DS) port on the card.
The IF downstream port ring and end tabs
are yellow. See Figure 3.
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.
Step 3 Connect the upstream cables to the
upstream ports on the card (US0—US5).

5 Removing the Card
To prevent the alarms from activating,
administratively shut down the card using the
shutdown command in interface configuration
mode before removing it from the chassis.
Step 1 Make sure that you are properly
grounded.
Step 2 Disconnect all the cables from the cable
interface line card.
Step 3 Unscrew the captive installation screws on
the faceplate.

Caution Always handle the cable interface line
card by the carrier edges and handle;
never touch the card's components or
connector pins.
Step 5 Place the card on an antistatic surface with
the component side facing up.
Note If the card is being returned to the factory,
immediately place it in a static shielding
bag and proper packaging for protection.
Caution For proper cooling and airflow,
always install a line card cover in an
empty line card slot.
6 Troubleshooting
Check the following:
1. Make sure that the card is securely seated in
the chassis.
If the captive screws do not tighten all the way,
the card is not properly seated in the chassis or
backplane. Carefully pull the card halfway out
of the slot, reinsert it, and tighten the captive
installation screws.
Caution A partially seated line card can cause
the router to reboot.
2. Are all enabled LEDs on?
If yes, the system is operational.
If no, check the following possibilities:
a. Verify that the card has been enabled and
configured for operation. The enabled
LED remains off when a card has not been
configured and enabled.
b. If a port is enabled but its corresponding
enabled LED is still off, check to see if the
card has pulled away from the backplane.
Reseat the card in its slot. (You do not
have to turn off the system power to do
this.) After the system reinitializes the
interfaces, the enabled LED on the card
should come on.
3. If the enabled LED remains off after the above
checks, it is likely that the system has detected
a processor hardware failure.
