Chapter 1 Cisco uBR10012 Universal Broadband Router Overview

Cable Interface Line Cards

The Cisco uBR10-LCP2adapter card and the Cisco uBR10-MC16xcable interface line cards (MC16C, MC16E, and MC16S) are mechanically connected to each other by means of brackets and power connectors (see Figure 1-17). The Cisco uBR10-LCP2 not only adapts the cable interface line card to the form factor of the Cisco uBR10012 series chassis, but also provides the following:

•Proper voltage conversion for the cards and chassis

•Boot code required to use the cable interface line cards

•SDRAM for buffering packets as they are transferred between the card and the PRE

The cards are inserted into and removed from the Cisco uBR10012 series chassis as a single logical and physical unit. All Cisco uBR10-LCP2-MC16xcable interface line cards support Online Insertion and Removal (OIR). OIR uses the MAC address assigned to the Cisco uBR10-LCP2 adapter card, allowing you to replace any Cisco uBR10-MC16xcable interface line card installed on the adapter card without losing the configuration information.

Caution Do not attempt to separate or remove the cable interface line card from the Cisco uBR10-LCP2 adapter card while the adapter card is inserted in the router. Remove the cards from the chassis as a unit and then separate them on a lab bench or other area that protects against ESD damage.

Figure 1-17shows the Cisco uBR10-LCP2 adapter card with the Cisco uBR-MC16C cable interface line card installed.
