This publication provides instructions for installing the Fiber Distributed Data Interface (FDDI) modules in an AGS+ router. These modules include the CSC-FCI or CSC-C2FCI ciscoBus interface cards and the four fiber-optic transceiver appliques, which provide single-mode and/or multimode network interfaces. The CSC-FCI operates with the CSC-CCTL ciscoBus controller card, and the CSC-C2FCI requires the second-generation CSC-CCTL2 ciscoBus controller card. The difference between the FCI and C2FCI cards is the presence of Microcode Version10.0 (or later) on the C2FCI and CCTL2 cards. Software Release 9.1 (or later) is required in order to use the C2FCI and CCTL2 cards. For specific compatibility information on upgrading the CSC-FCI card to Microcode Version10.0 or later, refer to the latest version of the publication Upgrading FDDI Cards to Microcode Version 2.1 or 10.1, Document Number 78-0857-xx (where xx is the latest version of the publication). Unless otherwise indicated, the name CSC-FCI will be used when configurations apply to both the CSC-FCI and CSC-C2FCI cards.
The following sections are included in this publication:
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.
Following is an overview of the FDDI components.
The CSC-FCI FDDI ciscoBus card is the interface for both single-mode and multimode FDDI network interfaces. It is connected to the ciscoBus and Multibus backplanes in the AGS+ router. Figure 1 shows the CSC-FCI card viewed from the component side.
The distance limitations for single-mode and multimode FDDI stations are listed in Table 1. Both FDDI modes provide 11 decibels (dB) of optical power.
| Transceiver Type | Maximum Distance Between Stations |
|---|---|
| Single-mode | Up to 6.2 mi (10 km) |
| Multimode | Up to 1.2 mi (2 km) |
The fiber-optic transceivers reside on circuit cards called appliques that provide the interface between external network connections and the internal CSC-FCI card. The four applique configurations are shown in Figures 2 through 5; each provides a unique combination of single-mode and/or multimode FDDI interfaces.
Following are the four FDDI applique mode combinations:
Both the single-mode and multimode transceivers provide a Class A dual attachment interface that can be connected to either a Class A or Class B station. Class A is a dual attachment station with primary and secondary rings; Class B is a single attachment station with only a primary ring.
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 cable (MIC). The MIC connector 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.
Following are the connectors typically used with single-mode and multimode FDDI applications.
Figure 6 shows the fiber-optic network interface cable FC-type connector typically used for single-mode FDDI applications with the APP-LSS, APP-LSM, and APP-LMS FDDI appliques.
 | Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode appliques when no fiber cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Laser Emission Requirement from CDRH FDDI. |
Figure 7 shows the fiber-optic MIC used for network and chassis connections with the APP-LMM, APP-LMS, and APP-LSM appliques.
Before installing any FDDI modules, ensure that your system meets the following prerequisites:
Use the show version command to verify the internal processor and software release you are running. If your current system configuration does not meet all of the above requirements, contact your customer service representative for information on hardware and software upgrades.
Follow these guidelines when working with any electrical equipment:
In addition, use the guidelines that follow when working with any equipment that is connected to telephone wiring or other network cabling.
| Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode appliques when no fiber cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Laser Emission Requirement from CDRH FDDI. |
The CSC-FCI card operates with the CSC-CCTL ciscoBus controller, and the CSC-C2FCI operates with the CSC-CCTL2 ciscoBus controller. To convert a CSC-FCI card to a CSC-C2FCI card, Microcode Version 10.0 (or later) must be installed on the card. For the CSC-C2FCI to operate with the CSC-CCTL2, Microcode Version 10.0 or later must be installed on the CSC-CCTL2 card. Use the show controller fddi command to see the current version of microcode on the CSC-FCI card. Following is partial sample output of the show controller fddi command. The microcode version is given in the first line of the output; the remaining information is not important to this verification.
router> show controller fddi
FDDI 0, controller type 1.1, microcode version 2.1 ((or 10.1 for the CSC-C2FCI card)
(Additional information displayed is not required for this example.)
Before beginning installation, verify that you received all of the parts for the interface(s) you will install. In general, each applique requires one interface card, and every two appliques require one applique card cage. If any parts are missing, contact a customer service representative.
The following parts are necessary for each interface:
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment and impair electrical circuitry. It occurs when electronic components are improperly handled and can result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
 | Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |
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 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 fiber-optic network interface cable FC-type connector typically used for single-mode FDDI applications with the APP-LSS, APP-LSM, and APP-LMS FDDI appliques. 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:
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 slot available. 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+.

In an AGS+ shipped on or after October 1, 1991, the total power drawn by all installed cards must not exceed 300 watts (W) per chassis. In AGS+ 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 breaker used in the later chassis configuration.) Table 3 lists the power requirements for each card available for the AGS+.
| Card | Power (Watts) |
|---|---|
| CSC/3 | 31 |
| CSC/4 | 35 |
| CSC-ENVM | 10 |
| CSC-MC+ | 3 |
| CSC-MCI | 281 |
| CSC-SCI | 20 |
| CSC-R16M | 34 |

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.
The following example shows how to determine if you can add two new CSC-FCI cards to
an AGS+ (all values are in watts):
| One CSC-ENVM card | 1 x 10 = 10 |
| One CSC/4 processor card | 1 x 35 = 35 |
| One ciscoBus controller card | 1 x 29 = 29 |
| Two CSC-(C2)MEC6 cards | 2 x 22 = 44 |
| 14 Ethernet transceivers | 14 x 4 = 56 |
| Power requirement of present system | 174 (179 if the CSC-CCTL2 is used) |
| Available power budget | 300 - 174 = 126 (121 if the CSC-CCLT2 is used) |
| Two CSC-FCI cards are within power budget | 100 < 126 |
Following is the procedure for accessing the chassis interior:
| Warning Before accessing the chassis interior, turn off power to the chassis because hazardous voltages may exist in or near the power supply. Use extreme caution when working near the power supply. |
Step 1 Turn OFF power to the chassis and unplug it from AC power.
Step 2 If the chassis is rack-mounted, disconnect all external cables from the rear panel. Note where these cables were connected so you can easily reinstall them.
Step 3 Remove the chassis from the rack and transfer it to a desktop or work table.
Step 4 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 5 To access cards in the card cage, loosen the two thumbscrews and remove the front panel from the chassis. (See Figure 9.) If you wish to access cards in the card cage only, skip the next step.
Step 6 To access other system components, locate and remove the seven number 1 Phillips screws securing the top cover. (See Figure 9.) Set the top cover and screws aside.
Following is the procedure for installing a CSC-FCI card in the AGS+ card cage. Before proceeding, ensure that your system and equipment meet the requirements listed in the section "Installation Prerequisites" on page 6.
Step 1 Slip on an ESD wrist strap and connect it to the chassis as previously described.
Step 2 Grasp the 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 card into the predetermined ciscoBus slot in the system card cage.
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 card-cage slot. The ejectors close automatically when the card is properly seated.
Step 5 If you will immediately install FDDI appliques, leave the front access panel off; and proceed to the next section, "Installing the FDDI Applique."
If FDDI appliques are already in place, proceed to the section "Connecting Internal and External FDDI Cables" on page 18.
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.
The following procedure is only required if an FDDI applique is not already installed.
| Caution Before proceeding, follow the ESD prevention procedures described in the previous section to avoid possible equipment failure. |
| Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode appliques 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. |
Following is the procedure for installing the FDDI applique in the applique card cage.
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 back plate. 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 on 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 it 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.)
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.)
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 chassis rear panel with those in the applique card cage.
Step 3 Secure the card cage with the connector plate screws you removed earlier, leaving appropriate holes empty for the ground straps. See Figure 12 and Figure 13 for ground strap configurations.
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).
The ground strap, which is included with all appliques, grounds 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 five screws. Refer to Figure 12 while you install the short ground straps.
Step 1 Remove the Phillips screw from the top center of the 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 FDDI Cables" on page 18.
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 straps.
Step 1 Remove the Phillips screw from the top center of each applique.
Step 2 Position the ground strap so that it straddles both appliques and the rear panel of the chassis. Align the holes in the ground strap with those on the rear 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 FDDI Cables."
The four internal ribbon cables (permanently attached to the FDDI applique) attach to the four connectors on the front edge of the CSC-FCI card. The FDDI network interface cables attach to the FDDI applique and provide the external connections to your network. Before beginning these procedures, orient the chassis with the open card cage facing you.
The four internal ribbon cables are fixed to the applique and must be routed and attached to ports on the FCI card. The ribbon cables are labeled alphabetically depending on the number of appliques you will install. The FCI 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. The ribbon cables from your FDDI applique are labeled as follows:
Connect the four applique ribbon cables to the C2FCIT card as follows.
| Caution To prevent twisting the ribbon cables and causing a possible short circuit, individually route each cable (from the FDDI applique) under the main card cage through the space provided and then up to the corresponding FCI card connector. |
Step 1 Connect the applique ribbon cable P3 A, E, I or M (the second cable from the left in
Figure 15) to the 26-pin connector labeled FDDI A, E, I, or M on the far-left front edge of the FCI card shown in Figure 14.
Step 2 Connect the applique ribbon cable P2 B, F, J, or N (the second cable from the right in
Figure 15) to the 26-pin connector labeled FDDI B, F, J, or N in Figure 14.
Step 3 Connect the applique ribbon cable P1 C, G, K, or O (the far-right cable in Figure 15) to the 26-pin connector labeled FDDI C, G, K, or O in Figure 14.
Step 4 Connect the applique ribbon cable P4 D, H, L, or P (the far-left cable in Figure 15) to the far-right (16-pin) connector labeled FDDI D, H, L, or P in Figure 14.
| FDDI Ribbon Cable | From Connector | To CSC-C2FCI Connector |
|---|---|---|
| FDDI A, E, I, or M | P3 | FDDI A, E, I, or M |
| FDDI B, F, J, or N | P2 | FDDI B, F, J, or N |
| FDDI C, G, K, or O | P1 | FDDI C, G, K, or O |
| FDDI D, H, L, or P | P4 | FDDI D, H, L, or P |
Following is the procedure for connecting the external FDDI cables. Refer to Figure 6 for an illustration of the single-mode FDDI connector and to Figure 7 for illustrations of the single-mode and multimode FDDI connectors.
| Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode appliques when no fiber cable is connected. Avoid exposure and do not stare into open apertures. This product meets the Class 1 Laser Emission Requirement from CDRH FDDI. |
Step 1 If you are not installing an optical bypass switch, skip to step 3.
Plug the male DIN connector (from the optical bypass switch) into the female DIN connector on the APP-LMM applique, then plug the fiber-optic MIC cables from the bypass switch into the PHY-A and PHY-B connectors on the FDDI applique.
Connect the FDDI cables from the network into the PHY-A and PHY-B connectors on the optical bypass switch. Up to 100 milliamperes of current can be supplied to the optical bypass switch. A pinout of the DIN connector on the optical bypass switch is listed in Table 5.
| Pin No. | Description |
|---|---|
| 1 | +5V to secondary switch |
| 2 | +5V to primary switch |
| 3 | Ground to enable primary switch |
| 4 | Ground to enable secondary switch |
| 5 | Sense circuit--1 kohm to +5V |
| 6 | Ground--sense circuit return |
Step 2 Multimode connections--Attach the fiber-optic MIC cables from the FDDI network to the PHY-A and PHY-B connectors on the applique. (See Figures 2 through 5.)
Single-mode connections--Attach the single-mode cables from the network to the appropriate transmit (XMT) A or B and receive (RCV) A or B connections on the FDDI applique.
| Caution Maintain the correct A to B and B to A relationship with the FDDI connectors. Failure to maintain this relationship will prevent the FDDI interface from initializing. For the optical bypass switch, PHY-A from the network goes to PHY-B on the switch, and PHY-B from the network goes to PHY-A on the switch. Some signal degradation will occur with the optical bypass switch installed in the FDDI ring. |
Step 3 Attach all other external cables to the appropriate applique connectors on the rear panel, and loosely place the top cover on the chassis. Leave the front panel off until you finish testing the installation.
After you have installed your card and applique, verify the installation by doing the following:
| Caution With the front access panel removed, the chassis is susceptible to overheating. Apply power to the chassis only long enough to go through the configuration dialog routine, check LEDs, and verify proper system operation. Replace the front access panel if it is necessary to leave on the power to the chassis for some time. |
Step 1 Turn ON the power and allow the system to boot up.
Step 2 Go through the configuration dialog routine (or use the setup command) to assign an address and subnet mask to each new FDDI interface you have installed.
Step 3 Observe the LED indicators on the applique and the ciscoBus controller card, then use EXEC show commands to verify that your interfaces are recognized by the system and have been assigned port (unit) addresses by the system.
Two separate sets of LEDs provide status about the installation: those on the CCTL2 card and those on the FDDI applique. The LEDs on the CCTL or CCTL2 card will verify the presence (and correct installation) of the C2FCIT cards in the ciscoBus backplane, while the LEDs on the applique report. First verify the CSC-CCTL indicators, then the applique indicators. The following sections discuss the LED indicators on the CSC-CCTL and CSC-CCTL2 cards.
The CSC-FCI card contains no LEDs or indicators. The LEDs on the ciscoBus controller (CSC-CCTL) card indicate when an interface is present in a ciscoBus slot. The CCTL contains a bank of 16 LEDs: four sets of four lights, and one set for each interface slot in the ciscoBus. (See Figure 16.)
On power-up, all LEDs are on, indicating that the CCTL card is active. Once the system is booted, and the ciscoBus card microcode has completed its discovery phase, the only LEDs that are on will be those that indicate the presence of a card in any ciscoBus slot. One LED from each set of four will light an interface card is detected. (The FDDI appliques also contain status LEDs whose descriptions follow.)
The numbers above each CCTL LED indicate the ciscoBus slot number. Verify that the LED for the ciscoBus slot in which your CSC-FCI card is installed comes on and remains on. If it does not, check the CSC-FCI to ensure that it is firmly seated in the ciscoBus backplane; the ejector levers snap into place when it is installed correctly. Figure 16 illustrates which LED will light to indicate the presence of a card in the ciscoBus.
The CSC-C2FCI card contains no LEDs or indicators. The LEDs on the CCTL2 card indicate when a ciscoBus interface is present in a ciscoBus slot. The front edge of the CCTL2 card contains a bank of five LEDs as shown in Figure 17 , one red LED for each interface slot in the ciscoBus, and a green (boot) LED to indicate a successful boot procedure.
One red LED will be on for each correctly connected ciscoBus card using the correct version of microcode. It will not be on if the card is incorrectly connected or if the microcode version is wrong.
On power-up, all five LEDs are on indicating that the CCTL2 card is active. Once the system is booted, and the ciscoBus controller card microcode has completed its discovery phase, the only red LEDs on will be those that indicate the presence of a card in a ciscoBus slot. The green LED is also on to indicate a successful boot operation. Figure 17 illustrates which LED will be on to indicate the presence of a card in the ciscoBus slot. The numbers above each LED (3, 2, 1, and 0 from left to right) indicate the ciscoBus slot number assigned to that LED.
There are a series of nine LEDs located on each FDDI applique. These LEDs indicate the current line state of each of the two ports on the card. The applique LEDs are shown in Figure 18, and the line states they reflect are listed in Table 6.
| 0 | 1 | 2 | State |
|---|---|---|---|
On | On | On | Line State Unknown (LSU) |
| On | On | Off | Halt Line State (HLS) |
| On | Off | On | Master Line State (MLS) |
| On | Off | Off | Active Line State (ALS) |
| Off | On | On | Noise Line State (NLS) |
| Off | On | Off | Quiet Line State (QLS) |
| Off | Off | On | Idle Line State (ILS) |
| Off | Off | Off | Elasticity Buffer Overflow/Underflow (OVUF) |
When the ring is operational (when the line protocol is up), the LEDs will oscillate between ILS, ALS, and MLS. ILS will predominate, so LED 2 will glow most brightly; LED 0 will be slightly dimmer; and LED 1 will be almost completely dark. The X3T9.5 FDDI specification explains the meaning of these line states in detail.
When the status LEDs show that the applique is installed correctly, use EXEC commands to verify that the new FDDI interface is properly recognized by the system. When the system is started, the interface cards query the appliques for interface information.
The EXEC command show controller fddi displays the current internal status of the CSC-FCI card(s), including the interfaces and how the card has identified them. The display lists the interfaces connected to each CSC-FCI card, and indicates that the system has identified your new interface. The display does not indicate the state of the line or protocol.
Following is a partial sample display:
router# show controller fddi
FDDI 0, controller type 1.1, microcode version 2.1 (or 10.1 for the CSC-C2FCI card)
128 Kbytes of main memory, 4 Kbytes cache memory
22 system TX buffers, largest buffer size 1520
Restarts: 0 line down, 0 hung output, 0 controller error
Interface 0 is Ethernet0, station address aa00.0400.0134
15 total RX buffers, 11 buffer TX queue limit, buffer size 1520
Transmitter delay is 0 microseconds
To obtain more information about the interfaces, such as the state of the lines and protocol types, use the EXEC command show interface fddi to display statistics about each of the FDDI interfaces in the chassis. The first line of the show interface display names the interface and its unit address
(FDDI 0, 1, and so forth), and indicates whether the hardware and the line protocol are up or down. If the line protocol is down, the hardware is not functioning properly; ensure that the network interface is properly connected and terminated.
Following is a partial sample display:
router# show interface fddi
Fddi 0 is up, line protocol is up
Hardware type is cBus Fddi, hardware address is aa00.0400.0134
Internet address is 131.108.1.1, subnet mask is 255.255.255.0
MTU 4470 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255
Encapsulation is SNAP, loopback is not set, keepalive is not set
ARP type: SNAP
Phy-A state is active, neighbor is B, cmt signal bits 08/20C, status ILS
Brk 1, Con 1, Tra 0, Nxt 11, Sig 10, Join 1, Vfy 1, Act 1
Phy-B state is active, neighbor is A, cmt signal bits 20C/08, status ALS
Brk 1, Con 1, Tra 0, Nxt 11, Sig 10, Join 1, Vfy 1, Act 1
CFM is wrap A, token rotation 5000 usec, ring operational 0:01:42
You can also use the show interface command (without variables) to display all network interfaces installed in the AGS+. Each new FDDI interface should be appended to the list of existing interfaces, with the next sequential number assigned to it. For more specific information on the available show commands, refer to the refer to the Router Products Configuration Guide and Router Products Command Reference publications.
After the FDDI module installation tests successfully, take the following steps:
Step 1 Turn OFF the system power and unplug the power cable.
Step 2 Replace and secure the top cover and front panel of chassis.
Step 3 Install the system in the network.
This completes the installation of the FDDI card and the FDDI applique.
