8-port OC-3c/STM-1 ATM Line Card Overview
The 8-port OC-3c/STM-1 ATM line card supports traffic shaping, and delivers line rate OC-3c/STM-1
bandwidth while performing traffic shaping and per-virtual circuit (VC) queueing. It also supports
per-VC Modified Deficit Round Robin (MDRR) and per-VC low latency queueing (LLQ).
MDRR is implemented on a per-VC basis, with up to eight queues per VC. One of the queues is a low
latency queue. Both per-VC WRED and per-VC MDRR are performed in hardware.
The 8-port OC-3c/STM-1 ATM line card provides the Cisco 12000 Series Router with eight 155 Mbps
ATM interfaces. The card interfaces to the router’s switch fabric and provides eight OC-3c/STM-1 SC
connectors for duplex single-mode or multimode SONET/SDH connections.

4-port OC-12c/STM-4c ISE and 4-port OC-3c/STM-1 ISE ATM Line Card
Overview
The 4-port ISE ATM line cards provide the Cisco 12000 series routers with an ATM line card that offers
the IP services engine or Engine 3 features, including extensive traffic queuing, shaping, and congestion
management features, at a sustained full duplex throughput of 5.66 million cells per second (4-port
OC-12c/STM-4c ISE ATM line card) or 1.41 million cells per second (4-port OC-3c/STM-1 ISE ATM
line card). The 4-port ISE ATM line card is available with either OC-12c/STM-4c or OC-3c/STM-1
interfaces. Except for the speed of the interfaces, these line cards provide identical functionality, and are
referred to throughout this document as the 4-port ISE ATM line cards.
The 4-port ISE ATM line card delivers a robust set of edge packet processing features such as ACL,
ExACL, CAR, NetFlow, and Multicast with incorporated MDRR, WRED and backpressure congestion
avoidance mechanism. This line card brings enhanced Layer 3 processing and high bandwidth ATM
capabilities to the Cisco 12000 series router.
In addition, the 4-port ISE ATM line cards provide Layer 2 AToM tunneling with cell relay and cell
packing on VCs, VPs, and interfaces; ATM traffic shaping and policing; and Layer 2 and Layer 3
configurations on the same port.
The line cards consist of two boards: a generic IP services engine motherboard that contains the Engine 3
chip set and fabric interface and a physical layer interface module (PLIM)-specific card providing the
four optic interfaces.

ATM Line Card Installation and Configuration
OL-13004-01
Removing and Installing a Line Card
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI)
shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap
whenever you are handling network equipment or one of its components.
The following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to an ESD connection socket on the router or to
bare metal on the chassis.
•Handle ATM line cards by the captive installation screws, the provided handle, ejector levers, or the
line card metal carrier only; avoid touching the board or connector pins.
•Place removed ATM line cards board-side-up on an antistatic surface or in a static shielding bag. If
you plan to return the component to the factory, immediately place it in a static shielding bag.
•Avoid contact between the ATM line cards and clothing. The wrist strap only protects the board from
ESD voltages on the body; ESD voltages on clothing can still cause damage.
Warning For safety, periodically check the resistance value of the ESD strap. The measurement should be
between 1 and 10 megohms.
Required Tools and Equipment
You need the following tools and parts to remove and install ATM line cards:
•Flat-blade or Phillips screwdriver
•ESD-preventive wrist or ankle strap and instructions
•Interface cables to connect the ATM line card with another router or switch
See the “Fiber-Optic Network Interface Cables” section on page 24 for cable details.
Removing and Installing a Line Card
This section describes the procedures for removing and installing a line card and includes the following
sections:
•Guidelines for Line Card Removal and Installation, page 9
•Removing a Line Card, page 10
•Removing the Blank Filler, page 12
•Installing a Blank Filler, page 12
•Installing a Line Card, page 14

ATM Line Card Installation and Configuration
OL-13004-01
Removing and Installing a Line Card
Note The installation and removal procedure for the ATM line card is different for the Cisco 12008 and
Cisco 12012 routers than for the other Cisco 12000 series routers. Make sure you refer to the
procedure that corresponds to your router chassis.
Caution To avoid erroneous failure messages, remove or insert only one line card at a time. After inserting or
removing a line card, allow at least 15 seconds before removing or inserting another line card, so that
the router can reinitialize and note the current configuration of all interfaces.
After removing and inserting a line card into the same slot, allow at least 60 seconds before removing
or inserting another line card.
Guidelines for Line Card Removal and Installation
Guidelines for line card removal and installation include the following:
•Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while
the router is operating. OIR is seamless to users on the network, maintains all routing information,
and ensures session preservation.
Note With OIR, notifying the software or resetting the power is not required. However, you have the
option of using the shutdown command before removing a line card.
•After you reinstall a line card, the router automatically downloads the necessary software from the
route processor (RP). Next, the router brings online only those interfaces that match the current
configuration and were previously configured as administratively up. You must configure all others
with the configure command.
Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove
or insert only one line card at a time. Allow at least 15 seconds for the router to complete the
preceding tasks before removing or inserting another line card.
After removing and inserting a line card into the same slot, allow at least 60 seconds before
removing or inserting another line card.
•Line cards have two ejector levers to release the card from its backplane connector. Use the levers
when you are removing the line card and to seat the line card firmly in its backplane connector when
you are installing the line card. The ejector levers align and seat the card connectors in the
backplane.

10
ATM Line Card Installation and Configuration
OL-13004-01
Removing and Installing a Line Card
Caution When you remove a line card, always use the ejector levers to ensure that the connector pins
disconnect from the backplane in the sequence expected by the router. Any card that is only
partially connected to the backplane can halt the router.
When you install a line card, always use the ejector levers to ensure that the card is correctly
aligned with the backplane connector; the connector pins should make contact with the
backplane in the correct order, indicating that the card is fully seated in the backplane. If a
card is only partially seated in the backplane, the router will hang and subsequently crash.
•The 4-port ISE ATM line card requires two slots when installed into a Cisco 12008 or Cisco 12012
Router. Before installing the line card, you must install the blank filler (part number:
4OC12X/ATM-BLANK) into the rightmost of the two slots. For detailed instructions, see the
“Installing a Blank Filler” section on page 12.
For line card configuration information, see the “Configuring and Troubleshooting Interfaces” section
on page 32.
Removing a Line Card
If you are replacing a failed line card, remove the existing line card first, then install the new line card
in the same slot. To remove a line card, use Figure 6 as a reference and follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to
the ports on the line card.
Step 3 Detach the line card cable-management bracket from the line card.
Step 4 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 6a.)

Removing and Installing a Line Card
Figure 6 Line Card Removal and Installation
Caution When you remove a line card, always use the ejector levers to ensure that the line card connector pins
disconnect from the backplane in the logical sequence expected by the router. Any line card that is only
partially connected to the backplane can halt the router.
Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane
connector. (See Figure 6b.)
Step 6 Grasp the ejector levers and pull the line card halfway out of the slot.
Step 7 Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card
to guide it. (See Figure 6c.) Avoid touching the line card printed circuit board, components, or any
connector pins.
Step 8 Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan
to return it to the factory.
Step 9 If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK)
to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure
the line card blank to the chassis by tightening its captive screws.
Note If you are removing a 4-port ISE ATM line card from a Cisco 12008 or Cisco 12012 Router chassis, you
must also remove the blank filler that accompanies the ATM line card. See the “Removing the Blank
Filler” section on page 12.

ATM Line Card Installation and Configuration
OL-13004-01
Removing and Installing a Line Card
Note When removing the 4-port ISE ATM line card, take into account that it weighs approximately 13.2 lb
(6 kg).
Removing the Blank Filler
This procedure only applies to 4-port ISE ATM line cards in Cisco 12008 and Cisco 12012 routers.
Because the 4-port ISE ATM line card is wider than the line card slots in the Cisco 12008 and Cisco
12012 Routers, the line card uses the space of two slots. The blank filler (part number:
4OC12X/ATM-BLANK) is used to fill the remaining area not used in the second slot, thereby providing
proper ventilation for the line card and protecting the chassis and line card from damage.
The blank filler is removed after the ATM line card has been removed.
Caution Do not attempt to remove the blank filler before completely removing the ATM line card from the
chassis. (See the “Removing a Line Card” section on page 10 for more information.) You must remove
the blank filler from the chassis before you can install any other line cards into the slot besides the ATM
line card.
To remove the blank filler, follow these steps:
Step 1 Use a screwdriver to loosen the captive screw at each end of the blank filler faceplate.
Step 2 Grasp the blank filler faceplate with one hand and pull the blank filler straight out of the slot, keeping
your other hand under the blank filler to guide it.
This completes the procedure for removing the blank filler. The router slot can now be used to install
any line card.
Installing a Blank Filler
This procedure only applies to 4-port ISE ATM line cards in Cisco 12008 and Cisco 12012 routers.
Because the 4-port ISE ATM line card is wider than the line card slots in the Cisco 12008 and
Cisco 12012 routers, the 4-port ISE ATM line card uses the space of two line card slots. The blank filler
is used to fill the remaining area not used in the second slot, thereby providing proper ventilation for the
line card and protecting the chassis and line card from damage.
The ATM line card can be installed into any available pair of slots in the Cisco 12008 or Cisco 12012
router. The blank filler is installed into the rightmost slot of the pair to be used by the line card.
Caution You must install a blank filler before installing a ATM line card in a Cisco 12008 or Cisco 12012 router.
To install a blank filler, follow these steps:

ATM Line Card Installation and Configuration
OL-13004-01
Removing and Installing a Line Card
Step 1 Choose an available pair of slots for the line card, and verify that the fiber-optic interface cables for the
line card are long enough for you to reach the line card ports and connect the line card to any external
equipment.
Step 2 Grasp the faceplate of the blank filler with one hand and place your other hand under the blank filler;
position the card for insertion into the rightmost card cage slot of the pair of slots to be used by the ATM
line card.
Figure 7 Inserting and Removing the Blank Filler
Step 3 Carefully slide the blank filler into the slot, making sure that the runners on the top and bottom of the
blank filler are positioned within the card cage slot runners.
Step 4 Use a screwdriver to tighten the captive screw on each end of the blank filler faceplate to ensure proper
EMI shielding and to provide proper ventilation for the ATM line card. These screws must be tightened
to meet electromagnetic interference (EMI) specifications. (See Figure 8.)

Step 2 Choose an available line card slot for the line card, and verify that the line card interface cable is long
enough for you to connect the line card with any external equipment.
Note If you are installing a 4-port ATM ISE line card into a Cisco 12008 or Cisco 12012 Router, you must
install the line card into the slot to the left of the blank filler.
Caution To prevent ESD damage, handle line cards by the captive installation screws, the provided handle, ejector
levers, or the card carrier edges only. Do not touch any of the electrical components or circuitry.
Step 3 Grasp the faceplate (or handle) of the line card with one hand and place your other hand under the card
carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid
touching the line card printed circuit board, components, or any connector pins.
Step 4 Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card
cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try
reinserting the line card until the ejector lever hooks are fully latched. (See Figure 9.)

When inserting a card, make
sure the ejector lever hooks
catch the lip of the card cage.

Removing and Installing a Line Card
Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned
with the backplane connector, the card connector pins make contact with the backplane in the correct
order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane
can cause the router to hang and subsequently crash.
Step 5 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card
faceplate. This action firmly seats the card in the backplane.
Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the line card faceplate
to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the
backplane.
Caution To ensure adequate space for additional line cards, always tighten the captive installation screws on each
newly installed line card before you insert any additional line cards. These screws also prevent accidental
removal and provide proper grounding and EMI shielding for the router.
Step 7 Install the cable-management bracket.
Step 8 Install the interface cables.
Note For information on installing cable-management brackets, see the “Installing a Line Card
Cable-Management Bracket” section on page 21.
For information on installing interface cables, see the “Cabling and Specifications” section on page 22.
For information on installing a blank filler before installing the 4-port ISE ATM line card, see the
“Installing a Blank Filler” section on page 12.
When the 4-port ISE ATM line card is installed in a Cisco 12008 or Cisco 12012 router together with
the blank filler, it will appear as in Figure 10.

Note The illustrations in this section show various line cards, but the line card cable-management bracket
installation procedure is the same regardless of the specific line card.
Cisco 12000 Series Routers include a cable-management system that organizes the interface cables
entering and exiting the router, keeping them out of the way and free of sharp bends.
Caution Excessive bending of interface cables can damage the cables.

Line Card Cable-Management Bracket
Note When shipped with spare line card orders, the cable-management bracket is not attached to the line card.
You must attach the cable-management bracket to the line card before you insert the line card into the
router.
Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The
cable-management bracket is designed to hold the interface cables and may break if you use the bracket
to push, pull, or carry the line card after it is removed from the router.
Removing and installing the line card cable-management bracket is described in the following
procedures:
•Removing a Line Card Cable-Management Bracket, page 19
•Installing a Line Card Cable-Management Bracket, page 21
Removing a Line Card Cable-Management Bracket
To remove a line card cable-management bracket, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Note the current interface cable connections to the ports on each line card.
Step 3 Starting with the interface cable for the bottom port on the line card, disconnect the cable from the line
card interface.
Note It is not necessary to remove the interface cables from the line card cable-management bracket. The
bracket (with attached cables) can be hooked to the cable-management tray or a bracket on the chassis
until a new line card is installed.
Step 4 For multiport line card cable-management brackets, proceed upward and remove the interface from the
Velcro strap on the end of the cable standoff. (See Figure 13.)
For single-port line card cable-management brackets, carefully remove the interface cable from the cable
clip. (See Figure 14.) Avoid any kinks or sharp bends in the cable.
Step 5 Repeat Step 3 and Step 4 for all remaining interface cables, then proceed to Step 6.
Step 6 For multiport line card cable-management brackets, loosen the captive installation screw at each end of
the cable-management bracket and remove the bracket from the line card.
For single-port line card cable-management brackets, loosen the captive installation screw on the
cable-management bracket and remove the bracket from the line card.
