Installing the CSC-MEC and CSC-C2MEC
Multiport Ethernet Controller Cards

78-0716-02

Product Numbers: CSC-MEC2=, CSC-MEC4=, CSC-MEC6=, CSC-C2MEC2=, CSC-C2MEC4=, and
CSC-C2MEC6=

This document provides the procedures for installing the ciscoBus multiport Ethernet controller
cards (CSC-MEC and CSC-C2MEC) in your AGS+ router. The CSC-MEC is compatible only with
the first-generation ciscoBus controller card (CSC-CCTL); the CSC-C2MEC is compatible only
with the second-generation ciscoBus controller card (CSC-CCTL2). ciscoBus compatibility is
described in the section, “Configuring the CSC-MEC and CSC-C2MEC Cards,” on page 9.

 In the following sections, the terms CSC-MEC or MEC are used to indicate both cards unless
otherwise indicated. The CSC-MEC and CSC-C2MEC differ only by firmware version; the
CSC-C2MEC works only with the CSC-CCTL2. There are two hardware versions of the CSC-MEC:
Version 5.0 and Version 5.1. Version 5.1 CSC-MEC cards can be used as CSC-C2MEC cards (with
Microcode Version 10.0 or later), but Version 5.0 CSC-MEC cards cannot be used as CSC-C2MEC
cards.

The CSC-MEC card occupies a ciscoBus slot in the system card cage. Standard 15-pin or 10BaseT
Ethernet appliques, which are installed on connector plates in the rear of the chassis, provide the
interface between the CSC-MEC card and your 802.3/Ethernet Version 2 or Version 1 network.

The sections in this document include the following:

Description of Parts, page 2

Installation Prerequisites, page 7

CSC-MEC Card, page 2

Configuring the CSC-MEC and CSC-C2MEC Cards, page 9

ciscoBus Configuration Considerations, page 10

Installation, page 17

Configuring the Interfaces, page 26

With the exception of compatibility requirements and the LEDs used to verify the installation, the
procedures are the same for both the CSC-MEC (first-generation ciscoBus) and CSC-C2MEC
(second-generation ciscoBus) cards.
