This document contains instructions for installing the multiport ciscoBus Token Ring interface card

(CSC-C2CTR) and Token Ring applique (APP-LTR2) in your AGS+ chassis. This document also

provides instructions for upgrading the C2CTR microcode by replacing a single erasable

programmable read-only memory (EPROM) component on the CSC-C2CTR card. The

CSC-C2CTR provides two or four high-speed Token Ring interfaces for connection to IEEE 802.5

and IBM-compatible Token Ring media at speeds of 4 or 16 Mbps. The APP-LTR2 provides the

interface between the CSC-C2CTR and your Token Ring network. Both the card and applique must

be installed in an AGS+ with a CSC/3 or CSC/4 processor card and a ciscoBus II controller card

(CSC-CCTL2).

Product Descriptions

The following sections contain physical descriptions and brief functional overviews of the

CSC-C2CTR card and the APP-LTR2 applique.

The CSC-C2CTR resides in the AGS+ system card cage. Each port on the CSC-C2CTR provides

one Token Ring interface and connects to an APP-LTR2 applique with an internally routed ribbon

cable. The APP-LTR2, which resides in an applique card cage, are installed in the two far right large

plate areas in the rear of the AGS+. The appliques provide the external interface to the Token Ring

network.

A typical installation, showing the interface card, the (internal) interface cable, and the interface

applique, is shown in Figure 1. The system card cage and applique card cages are not included in the

drawing in order to more clearly show the cable routing.

CSC-C2CTR Interface Card

The CSC-C2CTR, shown in Figure 2, contains four ports. The card supports two interfaces when

used with one APP-LTR2 and four interfaces when used with two APP-LTR2s. Each port (interface)

is individually conﬁgured to operate at 4 or 16 Mbps. The C2CTR-speciﬁc microcode (ﬁrmware)

resides on an EPROM in socket position U98, which may need to be replaced when the system

software is upgraded or when operating enhancements are implemented. Instructions for the

microcode upgrade can be found in the section “Upgrading Microcode” on page 34.

Figure 2 CSC-C2CTR ciscoBus Token Ring Card—Component-Side View

The four interface ports are numbered from left to right TR 0 through TR 3 when viewing the card

as installed in the system card cage. (See Figure 3.) Each port is connected to an APP-LTR2 with an

internal ribbon cable. Four green LEDs indicate the status of each port (interface). When an interface

is up, or active in the ring, the corresponding LED is on. The LED is off when the interface is

inactive, administratively down, not internally connected to the applique, or the applique is not

externally connected to the ring.

Figure 3 CSC-C2CTR ciscoBus Token Ring Card—Front-Edge View

The C2 designator in the product number indicates that the CSC-C2CTR card must be installed in

an AGS+ with a ciscoBus II controller card (CSC-CCTL2). The CSC-C2CTR can be installed in any

available ciscoBus slot except the center slot, which contains the CSC-CCTL2. However, for

optimum performance, the CSC-C2CTR should be installed in the highest-priority slot available in

accordance with the slot priority scheme described on page 9. Instructions for determining your

current system software version and the type of ciscoBus controller installed are provided in the

section “System Compatibility Requirements” on page 6.

Product Descriptions

APP-LTR2 Applique

The APP-LTR2, shown in Figure 4, provides the required high-speed interfaces between the

CSC-C2CTR and your Token Ring network. Each applique contains two female DB-9 Token Ring

connectors and the Media Access Control (MAC) circuitry for each interface. The green power LED

goes on to indicate the applique is receiving power from the CSC-C2CTR. Two ribbon cables

provide the internal connection between the applique and two ports on the CSC-C2CTR.

Figure 4 APP-LTR2 Applique

The APP-LTR2 is installed in an applique card cage mounted on the rear panel of an AGS+. One or

two appliques can be installed in each card cage. Because of internal space limitations, no more than

two applique card cages can be installed in the AGS+ chassis; therefore, a maximum of four

APP-LTR2s can be installed. A grounding strap, which is included with the applique, must also be

installed to prevent noise on the interface. Detailed instructions for installing the applique and card

cage are provided in the section “Installing the APP-LTR2 Applique” on page 20.

6ciscoBus Token Ring Card and Applique Installation and Upgrade Instructions

Installation Prerequisites

This section describes the minimum compatibility requirements that your system hardware and

software must meet before you install a new CSC-C2CTR. It describes the various commands you

can use to verify the compatibility requirements.

System Compatibility Requirements

Before installing a new CSC-C2CTR, ensure that your existing system components meet the

following minimum conﬁguration requirements for compatibility with the card:

•An AGS+ with a CSC/3 or CSC/4 processor card.

•The system is running Software Release 9.1 or later.

•A CSC-CCTL2 ciscoBus 2 controller card (Controller Type 6.0 or later) is installed.

•All ciscoBus interface cards are compatible with the CSC-CCTL2. (All must be running

Microcode Version 10.0 or later.) If you are replacing a CSC-CCTL with a CSC-CCTL2, you

must also upgrade all existing ciscoBus interfaces to Microcode Version 10.0 (or later) at the

same time you replace the ciscoBus controller card.

•All Multibus Token Ring interface cards meet the following requirements:

—CSC-1R and CSC-2R microcode is Version 1.2 or later.

—CSC-R16M microcode is Version 3.2 or later.

Refer to the section “Compatibility with Other Cards” on page 15 for compatibility requirements

for all ciscoBus and Multibus cards when running Software Release 9.1 (required for

CSC-C2CTR and CSC-CCTL2 operation).

•An applique card cage (product number MAS-CCG) is installed in the chassis, and there is at

least one empty slot available.

You received a new card cage in which the APP-LTR2 is already installed.

•There is a ciscoBus slot available (empty) for each CSC-C2CTR you will install.

You can display the current software version and the type of processor card installed with the show

version command. The current system software version is displayed in the ﬁrst line of the output,

8ciscoBus Token Ring Card and Applique Installation and Upgrade Instructions

Installation Prerequisites

For ﬁeld descriptions and additional commands, refer to the Router Products Conﬁguration Guide

and Router Products Command Reference publications.

Note If your system software, ciscoBus controller, or other interface cards in your system do not

meet the preceding compatibility requirements, contact a customer service representative.

ciscoBus Conﬁguration

Before installing a new CSC-C2CTR, ensure that all ciscoBus interface cards are the C2 type (all

have Microcode Version 10.0 or later installed), that any new ciscoBus cards you are installing will

not exceed the maximum port limits for ciscoBus interfaces, and that the ciscoBus cards will be

placed in the correct order of priority in the ciscoBus slots. The following sections describe how to

determine all of these requirements.

ciscoBus Controller Compatibility

All ciscoBus interface cards, which are listed in Table 1, contain card-speciﬁc microcode that

determines whether the card is compatible with the ﬁrst- or second-generation ciscoBus controller

card. Following are compatibility guidelines:

•ciscoBus cards with microcode versions earlier than Version 10.0 are compatible only with the

ﬁrst-generation ciscoBus controller card (CSC-CCTL).

•ciscoBus cards with Microcode Version 10.0 or later are compatible only with the

second-generation ciscoBus controller card (CSC-CCTL2).

•The CSC-C2CTR and CSC-C2FCIT are compatible only with the CSC-CCTL2. The initial

release of both cards contained Microcode Version 10.0.

Table 1 CSC-CCTL2 Interface Card Compatibility Requirements

The C2 designator added to the name of a ciscoBus interface card indicates that the card is running

Microcode Version 10.0 or later and is, therefore, compatible with the second-generation ciscoBus

controller card, the CSC-CCTL2. With the exception of a Revision 5.0 CSC-MEC (see Note

following), the ﬁrst- and second-generation ciscoBus interface cards are otherwise the same. For

example, you can upgrade a revision 5.1 CSC-MEC to a CSC-C2MEC by replacing the microcode

with Version 10.0 or later. When you upgrade the microcode on the revision 5.1 CSC-MEC to

Version 10.0, the name of the card also changes from CSC-MEC to CSC-C2MEC to indicate that it

1. Only CSC-C2MEC Revision 5.1 or later is compatible with the CSC-CCTL2.

is CCTL2-compatible. When you replace a CSC-CCTL ciscoBus controller card with a

CSC-CCTL2 ciscoBus controller card, you must upgrade the microcode on all ciscoBus interface

cards to Microcode Version 10.0 or later.

Note Only a Revision 5.1 or later CSC-MEC can be upgraded to a CSC-C2MEC. If you have a

Revision 5.0 CSC-MEC, contact a customer service representative for upgrade information.

You can display a description of the current ciscoBus controller and ciscoBus interface cards with

the EXEC show controller cbus command, an example of which is shown on page 7. The name and

controller type of each ciscoBus card, the ciscoBus slot in which it is installed, and the microcode

version of each is displayed. (Additional statistical information is also displayed for each interface

card, but is omitted from the example.)

Slot Priority The system card cage, shown in Figure 5, has nine slots, ﬁve of which are designated ciscoBus slots.

The center ciscoBus slot is reserved for the ciscoBus controller card, leaving four ciscoBus slots

available for ciscoBus interface cards.

The system uses a slot priority scheme that assigns a priority to each ciscoBus card according to the

ciscoBus slot in which the card resides. The card in ciscoBus slot 0 receives the highest ciscoBus

priority, while the card in ciscoBus slot 3 receives the lowest ciscoBus priority.

Slot priorities are set to accommodate the amount of trafﬁc generated by each interface card and the

amount of card buffering required. Each ciscoBus interface card is placed in a speciﬁc slot with

regard to other ciscoBus interface cards, if any. The order of priority is the same for both ﬁrst- and

second-generation ciscoBus controllers, except that the cards with the C2 designation can only be

used with the CSC-CCTL2.

Following is a list of ciscoBus interface cards in order of priority, from highest to lowest:

1CSC-MEC and C2MEC (10 Mbps)

2CSC-C2CTR (16 Mbps)

3CSC-HSCI and C2HSCI with an APP-LHS applique (HSSI interface) (45 through 52 Mbps)

4CSC-FCI and C2FCI (100 Mbps)

5CSC-C2FCIT (100 Mbps)

6CSC-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. Follow with the CSC-FCI and C2FCI cards. Next, install

CSC-C2FCIT cards. Last, install the CSC-HSCI and C2HSCI cards with the APP-ULA (UltraNet)

applique. Always install cards in the lowest-numbered available slot. For example, if using only

CSC-C2HSCI cards (with APP-ULA), place the ﬁrst in slot 0, the second in slot 1, and so forth.
