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

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.

Figure 1 CSC-(C2)MEC6 Controller Type 5.1 The CSC-MEC card must be installed in a router that is running System Software Release 8.3 or later and that contains a CSC-CCTL ciscoBus controller card. The CSC-C2MEC must be installed in a router that is running System Software Release 9.1 or later and that contains a CSC-CCTL2 ciscoBus controller card. - Page 3 Description of Parts Ethernet Appliques Ethernet appliques provide the external interfaces for CSC-MEC card ports. One or more appliques are mounted on a connector plate, which is installed in the rear of the router. The 15-pin Ethernet connector applique connects to a 10Base5 (thick -wire), 10Base2 (thin-wire), or 10BaseT (UTP) network with the appropriate MAU or Ethernet transceiver.
- Page 4 The 15-pin Ethernet attachment unit interface (AUI) connector, shown in Figure 3, provides a standard Ethernet IEEE/802.3 connection between a CSC-MEC card port and the external Ethernet network. An Ethernet transceiver, which is required for use with this connector, provides the connection to thick-wire, thin-wire, twisted-pair, and other Ethernet media.

Installation Prerequisites ciscoBus Configuration Considerations Before installing the CSC-MEC in the card cage, ensure that you have the correct type of ciscoBus controller installed (CSC-CCTL or CSC-CCTL2) and that the ciscoBus interface cards will be placed in the correct slots per the slot priority requirements described in “Slot Priority,” on page 11. - Page 11 6 CSC-HSCI and C2HSCI with an APP-ULA applique (UltraNet interface) (125 Mbps) Install CSC-MEC or C2MEC cards in the lowest-numbered slots, beginning with slot 0 (which has the highest priority), followed by CSC-C2CTR cards. After all CSC-MEC and CSC-C2CTR cards are installed, install CSC-HSCI and C2HSCI cards with the APP-LHS applique in the lowest-numbered available slots.
- Page 12 Installation Prerequisites ciscoBus Port Limitations The CSC-MEC card will operate with any other ciscoBus interface cards; however, buffering and switching demands on the ciscoBus controller and processor card limit the number of interfaces that can be mixed without impeding performance of the high-speed ciscoBus interfaces.
- Page 13 Table 6 is an example of how the system assigns Ethernet interface addresses in a chassis with one CSC-MCI 2E2T card and two CSC-MEC6 cards. The CSC-MCI is a Multibus card, and the CSC-MEC is a ciscoBus card; therefore, the CSC-MCI interface addresses are assigned first. Table 6...

Page 17: Installation
The following sections describe the procedures for installing a CSC-MEC card and Ethernet appliques. The CSC-MEC card is installed in the system card cage, which you access by removing the access panel on the front of the chassis. To access the system card cage, it is not necessary to disconnect cables from the rear of the chassis, or to remove the top cover of the chassis. - Page 18 Slip on an ESD wrist strap and connect it to the chassis as described in “Preventing Electrostatic Discharge Damage,” on page 17. Note If you are installing a new CSC-MEC card, disregard steps 4 through 6; skip to step 7. Step 4 If you are replacing an existing CSC-MEC card, disconnect the cables from the front of the card to be removed.
- Page 19 Step 10 Place any additional CSC-MEC cards sequentially into slot 1, then 2, then 3. Step 11 If Ethernet appliques for all the CSC-MEC ports are already installed, connect the internal ribbon cables from each applique to the CSC-MEC ports. Refer to the labels on the cables, if any, and to the labels on the applique ports to ensure you connect the correct applique to each port.
- Page 20 Individual plates are secured with two screws, large plates with six. Caution If you are installing a 10BaseT applique, ensure that the CSC-MEC card jumpers are set for Ethernet Type 2 (IEEE 802.3). (Refer to the section “Cables” on page 5.)
- Page 21 LEDs indicate the presence (correct installation) of ciscoBus cards in the ciscoBus. The LEDs on the CSC-MEC card are on when the corresponding port (immediately to the right of each LED on the card) is connected to an external interface. If any 10BaseT appliques are installed, the LEDs on the applique indicate the state of that interface.
- Page 22 Installation ciscoBus Controller Card LEDs Depending upon whether you installed a CSC-MEC or a CSC-C2MEC, you will check the following ciscoBus controller card: • If you installed a CSC-MEC (first-generation ciscoBus interface card), check the LEDs on the CSC-CCTL ciscoBus controller card.
- Page 23 Installation CSC-MEC Card LEDs On the CSC-MEC, an LED is located to the right of each port. (See Figure 15.) After the system has booted, the LED for each connected port should be on. Ethernet 0 LED Ethernet 5 LED Figure 15 CSC-MEC Card—Front-Edge View...
- Page 24 Installation Restarting the System To check the installation, first verify the ciscoBus controller card LEDs, then the CSC-MEC LEDs, then any applique LEDs with the following steps. Before turning on the system power, ensure that you are able to access the rear of the chassis to observe the LEDs on the applique.
- Page 25 (See Figure 15.) If any LEDs for a connected port are not on, do the following: • If no LEDs on the CSC-MEC are on, turn OFF power to the system, remove and reseat the CSC-MEC, and reboot the system. •...
