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.

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.

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

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.)
