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

4 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques
FDDI Module Overview
The single-mode transceiver provides connectivity to single-mode FDDI fiber for distances up to
6.2 miles (10 kilometers). The connector is a simplex FC-type interface that accepts standard
8.2 to 10/125 micron ( 0.5) single-mode fiber-optic cable.
The multimode connectors are FDDI-standard physical (PMD) connectors. The connectors accept
FDDI standard 62.5/125 micron multimode fiber-optic cable using the media interface connector
(MIC). The MIC can also accept alternate cable sizes, such as 50, 85, or 100-micron multimode
fiber. Use care when using alternate fiber sizes, to avoid violating optical power budget restrictions.
The multimode/multimode applique also provides a DIN port for connecting an optional optical
bypass switch, which allows the light signal to pass directly from the receive port to the transmit
port. When this optical bypass is used, the signal is not repeated, and significant signal loss may
occur when transmitting to stations at maximum distances.

8 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques
Installation Prerequisites
System Compatibility
Followingarethephysicalrequirementsandlimitationsthat you must consider before installing new
FDDI components in your system. For example, to obtain optimum performance, you must ensure
that the new components are compatible with the existing system configuration and that you place
interface cards in the proper card-cage slots.
Your AGS+ must meet the following general compatibility requirements before you install a
C2FCIT card and associated appliques:
•Your AGS+ has a CSC/3 (or later) processor card running Software Release 9.1 or later.
•An applique card cage (Product Number MAS-CCG) is installed in the chassis with at least one
empty slot available, or you received a new card cage in which the FDDI applique is already
installed.
•The currently installed ciscoBus cards meet the rules provided in the section “Slot Priority” on
page 9.
•You have a second-generation ciscoBus card (CSC- CCTL2) installed; the first-generation
ciscoBus (CCTL) card is not compatible with the C2FCIT card.
•Your C2FCIT and CCTL2 cards must have Microcode Version 10.0 or later.
•Use the show version command to verify the type of processor card and software release and the
show controller cbus command to verify the microcode versions.
•Your site must have the appropriate network interface wiring with which you will connect the
router to your FDDI ring(s).
•To operate with the CCTL2 card, all other ciscoBus cards in the AGS+ must have Microcode
Version 10.0 or later (C2FCI, C2HSCI, and C2MEC, and so forth).
•The power budget of your chassis will not be exceeded by adding more C2FCIT cards. Current
draw for the C2FCIT and applique is 6.9A (7.7A with any traffic), and the power dissipation is
36W.
•Microcode upgrades—If you are upgrading to C2FCIT Microcode Version 10.3, your system
software must be Software Release 9.1(1) or later. For additional information, refer to the section
“Upgrading Microcode” on page 28.
Note If your current system configuration does not meet all of the above requirements, contact a
customer service representative for information on hardware and software upgrades.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment
andimpairelectricalcircuitry.Itoccurswhenelectroniccomponentsareimproperlyhandledandcan
result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
•Before you open a chassis, ensure that power to the unit is turned off, but that the power cord is
connected to the wall receptacle. Having the power cord connected will ensure a ground path for
any ESD voltages.
•Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin
contact.

Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques 9
Installation Prerequisites
•Connect the equipment end of the strap to an unpainted surface of the chassis frame or another
proper grounding point or surface. We recommend that you attach it to the inside bottom of the
chassis, or to the rear panel (inside or outside), without making contact with any connectors or
appliques.
•Avoidcontactbetween equipment and clothing. Thewrist strap only protectsthe equipment from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
•Handle printed circuit cards and appliques by the edges only; avoid touching the components,
traces, or any connector pins.
•Place a removed card component-side-up on an antistatic surface or in a static shielding bag. If
the component will be returned to the factory, immediately place it in a static shielding bag.
•Do not remove the wrist strap until the installation is complete.
Caution For safety, periodically check the resistance value of the antistatic strap. The
measurement should be between 1 and 10 mega ohms.
Slot Priority The AGS+ card cage, shown in Figure 8, has nine slots, five of which are designated ciscoBus slots.
The center ciscoBus slot is reserved for the ciscoBus card, leaving four ciscoBus slots available for
ciscoBus interface cards.
Figure 8 AGS+ Card Cage and Backplanes—Front View
Note The ciscoBus currently supports a maximum of four C2FCIT cards.
The AGS+ 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.

10 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques
Installation Prerequisites
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 cards, except that the cards with the designation C2 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 megabits per second [Mbps])
2CSC-C2CTR (16 Mbps)
3CSC-HSCI and C2HSCI with an APP-LHS applique (High-Speed Serial 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 slots available. 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 you are using
only CSC-C2HSCI cards (with APP-ULA), place the first in slot 0, the second in slot 1, and so forth.
Table 2 lists the maximum port and card configurations for all of the ciscoBus cards currently
available. Use this table as a guide when installing new ciscoBus cards and reconfiguring your
AGS+.

Installation Prerequisites
Calculating the Chassis Power Budget
In an AGS+ chassis shipped on or after October 1, 1991, the total power drawn by all installed cards
must not exceed 300 watts (W) per chassis. In chassis shipped before this date, the total power
cannot exceed 260W. (The earlier chassis contained a 5-amp [A] circuit breaker, rather than the 7.5A
circuit used in the later chassis configuration.) Table 3 lists the power requirements for each card
available for the AGS+.
Table 3 Interface Card Power Requirements
Before installing new cards, check the power requirements of the existing system and the new
card(s) to avoid exceeding the power budget. Calculate the power requirements of an existing
system by adding the values for each card in the chassis; the sum is the power requirement.
Determine the available power budget, subtract that sum from 300W (260W for chassis shipped
before 10/1/91); the result is the power budget available for new cards.

Installation Prerequisites
The following example shows how to determine if you can add two new CSC-C2FCIT cards to an
AGS+ (with all values in watts):
List of Required Parts and Tools
The following parts are necessary to install each new FDDI interface:
•One CSC-C2FCIT interface card.
•One FDDI applique (APP-LMM, APP-LMS, APP-LSM, or APP-LSS) for each CSC-C2FCIT
card.
•Applique card cage (MAS-CCG)—One card cage is required for every two appliques and might
already be installed in the AGS+ chassis.
•One ground strap (a short ground strap if the applique will be mounted next to a blank connector
plate,or a long ground strap if the applique willbe mounted next to anotherapplique that requires
a ground strap).
•Media-dependent external FDDI network interface cables (not included)—Two simplex cables
for each single-mode interface, one duplex cable for each multimode interface. Refer to the
section “FDDI Connectors” on page 6.
•One port address label for each applique (FDDI 0, FDDI 1, and so forth)—This label should be
attached to the applique when you receive it.
If you are upgrading the C2FCIT microcode, you also need one or more replacement components.
For instructions, proceed to the section “Upgrading Microcode” on page 28.
Verify that you received all the parts for the interfaces you will install. In general, each interface card
requires one applique, and every two appliques require one applique card cage. If any parts are
missing, contact a customer service representative.
Following are the tools required for installing interface cards and appliques:
•Flat-blade screwdriver (medium if you are removing the AGS+ front access panel for the first
time
•Number 1 Phillips screwdriver
•Chip extractor or IC removal tool (for microcode upgrades only)
•Needlenose pliers (for microcode upgrades only)
•ESD-preventive wrist strap (your own or the one provided with your FDDI component)
One CSC-ENVM card 1 x 10 = 10
One CSC/4 processor card 1 x 35 = 35
One CSC-CCTL2 card 1 x 34 = 34
Two CSC-C2MEC6 cards 2 x 22 = 44
One CSC-MCI 2E card 1 x 28 = 28

14 Installing and Upgrading the CSC-C2FCIT FDDI Card and Appliques
Installing Cards and Appliques
Setup Command Facility
Whenever you install new hardware components, the system automatically invokes the setup
command facility the first time the system is started. You can use setup to configure the new
interfaces, or exit from the setup command facility and configuring the new interfaces with the
configure EXEC command.
Before installing new interfaces, be prepared with the information you will need such as the
protocols you plan to route on each interface, IP addresses if you will configure the interfaces for IP,
and which interfaces, if any, will use bridging.
For detailed descriptions of setup and initial configuration procedures, refer to the Router Products
Getting Started Guide and Router Products Command Reference publications. The Router Products
Getting Started Guide and the Router Products Configuration and Reference publications provide
detailed descriptions and sample sessions of both the setup command and the configure command.
Installing Cards and Appliques
Following are the procedures described in this section:
•“Chassis Access Procedure” on page 14
•“Installing the C2FCIT Card” on page 15
•“Installing the FDDI Applique” on page 16
•“Connecting Internal and External Cables” on page 20
Before proceeding, ensure that your system and equipment meet the requirements listed in the
section “Installation Prerequisites” on page 7.
Chassis Access Procedure
Following is the procedure for accessing the chassis interior.
Warning Before accessing the chassis interior, turn off power to the chassis and unplug the power
cord because hazardous voltages may exist in or near the power supply. Use extreme caution when
working near the power supply.
Step 1 If you will need to handle any electronic components (cards, and so forth), attach
appropriate ESD protection and attach the AC power cord but, to prevent a shock hazard,
make certain the chassis power is OFF.
Step 2 To access cards in the card cage, loosen the two thumbscrews and remove the front panel
from the chassis. (See Figure 9.)
Note The front panel is secured with two thumbscrews, which are tightened with 12 in/lb of torque
for shipping. If you are removing the front panel for the first time, use the medium flat-blade
screwdriver to turn the thumbscrews counterclockwise to loosen them. When you replace the panel,
turn the thumbscrews clockwise until they are finger-tight.

Note To reassemble the chassis, reverse all steps.
Installing the C2FCIT Card
Following is the procedure for installing the C2FCIT card:
Step 1 Slip on an ESD-preventive wrist strap and connect it to the chassis as described in
“Preventing Electrostatic Discharge Damage” on page 8.
Caution To avoid possible equipment failure, follow the ESD-prevention procedures described
previously.
Step 2 Grasp the C2FCIT card ejector levers and position the card with the component side up and
the bus edge away from you. Handle the card as little as possible, and when you do handle
it try to make contact with only the ejector levers and card edges.
Step 3 Place the bus edge of the C2FCIT card into the predetermined ciscoBus slot in the system
card cage. For slot priority guidelines, refer to the section “Slot Priority” on page 9.
Note You will haveto use a moderate amount of force to push the card into the slot properly. Before
pushing the card into the slot, ensure that the card is aligned with the ciscoBus and Multibus slots
and that the chassis is firmly mounted on a stable surface.

Installing Cards and Appliques
Step 4 Place your thumbs on the ejector levers and push the card in firmly until it snaps into place
and is firmly seated in the slot. The ejector levers close automatically when the card is
properly seated.
Step 5 If you are going to install FDDI appliques immediately, leave the front access panel off and
proceed to the following section, “Installing the FDDI Applique.”
If FDDI appliques are already in place, leave the front access panel off and proceed to the
section “Connecting Internal and External Cables” on page 20.
Installing the FDDI Applique
The FDDI applique is installed in an applique card cage in the rear of the chassis; access to the rear
of the chassis requires removing the front panel and top cover of the chassis. (See Figure 9.) The
following procedure is required only if an FDDI applique is not already installed.
Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode
applique when no fiber cable is connected. Avoid exposure and do not stare into open apertures. This
product meets Class 1 Laser Emission Requirement from CDRH FDDI.
Installing the FDDI Applique in the Applique Card Cage
Following is the procedure for installing the FDDI applique in the applique card cage.
Note Before the FDDI applique is installed in the applique card cage, remove the applique card
cage from the chassis to make the installation easier. If you have a card cage assembly that is not
installed in the chassis, skip to step 4.
Step 1 If the applique card cage is installed in the chassis, disconnect any external connections to
the applique it contains.
Step 2 Remove the card cage from the chassis by removing the six screws that secure it to the rear
panel. Carefully lift the card cage up and out of the chassis, using care not to strain any
internal ribbon cables that still may be attached to interface cards in the system card cage.
Step 3 Remove the top cover of the applique card cage by loosening the four cover fasteners that
secure it. (See Figure 10.)

Step 4 If the card cage is empty, remove both filler plates from the rear. (See Figure 10.) If an
applique is currently installed, remove only the filler plate.
Step 5 If you are installing only one applique in an empty card cage, install the FDDI applique,
with its attached faceplate, into the right side of the card cage. (Orient the card cage as in
Figure 10 for the following steps.)
Step 6 Position the applique so the status LEDs are on the bottom. Ensure that the tab on the
bottom of the applique faceplate is inserted into the slot in the bottom of the applique card
cage and that the applique is seated in the card guide. (See Figure 10.)
Step 7 For one applique only—If you are installing only one FDDI applique, insert the blank
faceplate in the left side of the card cage, sliding it down so that the front edge aligns with
the faceplate on the right side of the card cage.
For two appliques only—If you are installing a second FDDI applique in the card cage,
install the applique in the left side of the card cage by sliding it down so that the faceplate
aligns with the faceplate of the applique on the right side of the card cage. Insert the
applique into the card cage with the status LEDs on the bottom. Ensure that the tab on the
bottom of the applique faceplate is inserted into the slot in the bottom of the applique card
cage and that the applique is seated in the card guide. (See Figure 10.)
Step 8 Replace the top cover of the applique card cage. Ensure correct alignment of the cover with
the two guide pins on the bottom of the cover. The guide pins should pass through the
alignment holes in the tabs on the top of each applique and faceplate assembly. Secure the
top cover to the card cage with the four cover fasteners. (See Figure 10.)

Installing Cards and Appliques
Installing the Applique Card Cage in the Chassis
The applique card cage can only be installed in one of the two large plate areas on the right side of
the rear panel of the chassis. (For the remainder of this procedure, orient the card cage and chassis
as shown in Figure 11.)
Note If you removed the card cage to install the applique, proceed to step 2. (The connector plate
area has already been removed.)
Figure 11 Installing the FDDI Applique and Card Cage in the AGS+ Chassis
Step 1 Remove a blank connector plate from one of the two right-side connector areas by
removing the six screws that secure it. (See Figure 11.)
Step 2 Place the applique card cage inside the rear of the chassis, in the empty large plate area.
(See Figure 11.) Align the screw holes in the rear panel of the chassis with those in the
applique card cage.
Step 3 Secure the card cage with the connector plate screws you removed earlier, leaving

Step 4 Attach the appropriate label (FDDI 0, FDDI 1, and so forth) to the lower part of the
applique faceplate; the label will be clearly visible in this position.
Step 5 Decide if your installation requires a short or long ground strap. Use a short ground strap
when you install the applique next to a blank connector plate (see Figure 12) or next to an
applique that does not contain a hole for the long ground strap screw. Use a long ground
strap when you install the applique next to an applique that contains a hole for the long
ground strap, for example, another FDDI applique (see Figure 13).
Installing a Short Ground Strap
Theground strap, which is included with all appliques, groundsthe applique to the chassisto prevent
EMI noise on your network interface. The applique card cage containing the FDDI appliques should
already be installed in the chassis and secured with five screws. Refer to Figure 12 while you install
the short ground strap.
Figure 12 Short Ground Strap Installation
Step 1 Remove the Phillips screw from the top center of each applique.
Step 2 Position the ground strap so that it straddles the applique and rear panel of the chassis.
Align the holes in the ground strap with those on the rear panel and the applique.
Step 3 Secure the ground strap with the two Phillips screws.
Step 4 Connect ground straps to other appliques as necessary, and proceed to the section,
“Connecting Internal and External Cables” on page 20.

Installing Cards and Appliques
Installing a Long Ground Strap
Ground straps, which are included with all appliques, ground the applique to the chassis to prevent
EMI noise on your network interface. The applique card cage containing the FDDI appliques should
already be installed in the chassis and secured with four screws. Refer to Figure 13 while you install
the long ground strap.
Figure 13 Long Ground Strap Installation,
Step 1 Remove the Phillips screw from the top center of each applique.
Step 2 Position the ground strapso that it straddles both appliquesand the rear panel of thechassis.
Align the holes in the ground strap with those on the back panel and the appliques.
Step 3 Secure the ground strap with the four Phillips screws.
Step 4 Connect ground straps to other appliques as necessary, and proceed to the next section,
“Connecting Internal and External Cables.”
Connecting Internal and External Cables
The four internal ribbon cables (permanently attached to the FDDI applique) attach to the four
connectors on the front edge of the C2FCIT card. The FDDI network interface cables attach to the
FDDI applique and provide the external connections to your network. Before beginning these
procedures, position the chassis with the open card cage facing you.
Connecting the Internal FDDI Ribbon Cables
The four internal ribbon cables are fixed to the applique and must be routed and attached to ports on
the C2FCIT card. The ribbon cables are labeled alphabetically depending on the number of
appliques you will install. The C2FCIT card connectors are shown in Figure 14, and the ribbon cable
connectors are listed in Table 4. The ribbon cable orientation and labeling for the FDDI applique is
shown in Figure 15.
