FDDI Module Overview

If you encounter a new problem and determine that it is not the result of this installation or upgrade,

refer to the AGS+ Hardware Installation and Maintenance publication for initial system startup

troubleshooting procedures, or to the Troubleshooting Internetworking Systems publication for

additional suggestions for resolving the problem.

FDDI Module Overview

The FDDI interface modules described in this document include the single-port FDDI

communications interface card with translational bridging (CSC-C2FCIT) and the four available

ﬁber-optic transceiver appliques. While incorporating all of the functions of the C2FCI card, the

C2FCIT card provides higher speeds than the C2FCI card as well as the following translational

bridging capabilities: FDDI to FDDI (transparent), FDDI to Ethernet, and FDDI to Token Ring.

Note

(or later) bridging software on the processor card. Both the C2FCIT and CCTL2 cards must have

Microcode Version 10.0 or later.

The C2FCIT card must be installed in an AGS+ router that is running Software Release 9.1 or later

and that contains a CSC/3 or CSC/4 processor card. The router must also contain a

ciscoBus2 (CSC-CCTL2) card (which is indicated by C2 in the product number).

C2FCIT cards can be installed in any of the four available ciscoBus slots in the system card cage. A

maximum of four C2FCIT cards is allowed in the AGS+, with one FDDI applique per C2FCIT card.

The FDDI appliques are installed in the rear of the chassis in an applique card cage (Product

Number MAS-CCG).

C2FCIT Card

The C2FCIT card (see Figure 1) is one of the two AGS+ FDDI interfaces for both single-mode and

multimode network interfaces. (The other FDDI interface card is the CSC-C2FCI.) The C2FCIT

card is connected to the ciscoBus and Multibus backplanes in the AGS+ router.

The CCTL2 card is backward compatible with the FCI, HSCI/Ultra, and MEC cards, providing all

have Microcode Version 10.0 or later, and the system is running Software Release 9.1 or later. An

FCI, HSCI, or MEC card with Microcode Version 10.0 or later will include in its name C2 (C2FCI,

C2HSCI/Ultra, and C2MEC), which indicates that the card has Microcode Version 10.0 or later and

can be used with the CCTL2 ciscoBus card.

2 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques

Using the translational bridging feature with the C2FCIT card requires Software Release 9.1
