1Purpose

This quick start guide shows you how to install a Cisco uBR-MC16 cable interface line card in the Cisco uBR7200 series router.

2Feature 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

3Prerequisites

•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.

4Installing 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 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.

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:

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).
