1 Feature Description

The Cisco uBR10-MC5X20S, U, and H cable
interface line cards transmit and receive RF signals
between the subscriber and the headend.
Frequency ranges:

• Cisco uBR10-MC5X20S—5–42 MHz

• Cisco uBR10-MC5X20U—5–65 MHz

• Cisco uBR10-MC5X20H—5–65 MHz

The Cisco uBR10-MC5X20S/U/H cards have five
downstream (DS) ports and twenty upstream (US)
ports. The US ports are either fixed to a specific DS
port or dynamically assigned to one or more DS
ports, depending on the Cisco IOS software
release.

2 Installing the Card

If you are replacing a Cisco uBR10-MC5X20S or U
card with a Cisco uBR10-MC5X20U or H card,
you must reconfigure the card.

Step 1 Make sure that you are grounded using an

ESD-preventive wrist or ankle strap.

Step 2 Remove the protective sticker covering the

DS ports.

Step 3 Verify that the ejector levers are open.

Step 4 Grasp the faceplate with one hand and

place your other hand under the card.

Step 5 Align the upper and lower edges of the

card with the upper and lower guides in
the chassis.

Step 6 Slide the card into the slot until you can

feel it seat in the backplane connectors.

Step 7 Close both ejector levers to secure the card

in the chassis. Engage and begin tightening
the captive screws first by hand. Then, use
either a T-10 Torx (included in the line
card accessory kit) or a common flathead
screwdriver to tighten the captive screws
between 5 to 7 in-lbs.

Caution Only tighten the captive screws to a

maximum of 7 in-lbs.

Tip Make sure that the captive screws are

secure for proper electromagnetic
interference (EMI) shielding.

Cabling the Card

Depending on your universal cable holder (UCH),
refer to Cabling the Cisco uBR10-MC5X20S/U/H

Interface Line Card with UCH1 Quick Start Guide

or Cabling the Cisco uBR10-MC5X20S/U/H

Interface Line Card with UCH2 Quick Start
Guide.

3 Removing the Card

Shut down the card interface before removing the
card from the chassis. Refer to “Shutting Down
and Restarting the Interface” in the

Cisco uBR10012 Software Configuration Guide.

If the maintenance LED is on, you can remove the
card without affecting system operations.

Removing the UCH

For more information about the universal cable
holders UCH1 and UCH2, refer to Cabling the

Cisco uBR10-MC5X20S/U/H Interface Line Card
with UCH1 and Cabling the Cisco uBR10­MC5X20S/U/H Interface Line Card with UCH2.

ESD-preventive wrist or ankle strap.

Step 2 Loosen the leadscrew (counterclockwise)

on the UCH until it is completely
disengaged from the faceplate.

Step 3 Pull the UCH straight away from the

faceplate using the leadscrew.

Caution Do not use the cables to pull the UCH

Removing the Card

Step 1 Using a T-10 TORX driver tool or flathead

screwdriver, unscrew the top and bottom
captive screws on the card.

Step 2 Simultaneously pivot both ejector levers

away from each other to disengage the
card from the backplane.

Caution The upconverter on the back side of the

card may be hot.

Step 3 Slide the card out of the slot and place it

on an antistatic surface with the
component side facing up.

Tip Always install a blank cover in an empty

slot to ensure proper cooling and airflow.

4 Troubleshooting

Check the following:

1. Verify that the LEDs light and go through the
power on self test (POST) when the card is
inserted in the chassis.

2. Verify that the captive screws and ejector
levers are secure.

3. Verify that the POWER LED is on (green). If
the LED off (not green):

a. Verify that there is power to the system.

b. Verify that the card is configured for the

system.
