OC-3c/OC-3c NI-2 Card

This section provides the following information about OC-3c/OC-3c NI-2 cards:

Features

In addition to the features described in the "Introduction" section, the OC-3c/OC-3c NI-2 card

Provides the network OC-3c WAN trunk interface through connectors located on the NI-2 card faceplate. The following two versions of the OC-3c/OC-3c NI-2 card are available to support the WAN trunk interface:

SMF intermediate range
MMF short range

Provides an OC-3c subtend interface through optical connectors located on the NI-2 card faceplate.
Controls timing and redundancy.

Note The BITS interface is connected through a header located on the back of the Cisco 6015 chassis, through the I/O card located on the back of the Cisco 6100, Cisco 6130, and Cisco 6160 chassis, or through the I/O module on the front of the Cisco 6260.

Redundancy is not supported on the Cisco 6015 and Cisco 6100 chassis.

Supports the aggregation of up to 12 subtended node chassis configured for OC-3c operation in a daisy chain configuration.

Note The I/O module does not function when you use an OC-3c/OC-3c NI-2 card in the Cisco 6015; however, an I/O module must be installed in the chassis for the system to operate correctly. The OC-3c/OC-3c NI-2 card does not support the DS3, E1, or T1 interface found on the front of the Cisco 6015 I/O module. Therefore, the trunk and subtending interfaces are provided on the front of the OC-3c/OC-3c NI-2 card.

The OC-3c/OC-3c NI-2 card can be used only in a commercial environment and does not work in an outside-plant environment. Either Cisco 6015 I/O module can be installed in conjunction with the OC-3c/OC-3c NI-2 card.

New versions of the OC-3c/OC-3c NI-2 card SMF and MMF (NI2-155SM-155SM2 and NI2-155MM-155MM2) support enhanced upstream bandwidth for use with the 8xG.SHDSL line card. For you to achieve maximum bandwidth rates for each 8xG.SHDSL, the updated boot image, ni2-dboot2-mz, must be running on the OC-3c/OC-3c NI-2 card.

Network Clocking Overview

The NI-2 card receives its network timing signal from any one of the following sources:

A BITS clock. When a BITS clock serves as the network timing signal source, the chassis receives a clock signal through designated pins on the I/O card, I/O module, or rear interface header (Cisco 6015) and distributes the signal through the chassis backplane.
An internal clock.
DS3, OC-3c, T1, or E1 network trunk interface. An NI-2 card synchronizes with the network timing source and provides a clock reference signal to line cards in the chassis and to subtended node chassis.

Note For more information about network clocking with a subtended configuration or for more information about connecting the BITS clock, refer to the appropriate hardware installation guide.

Redundancy Overview

Redundancy is available for Cisco 6130, Cisco 6160, and Cisco 6260 systems. The following forms of redundancy are available:

NI-2 card cold redundancy, which allows a standby NI-2 card to take over system operations in the event of a complete failure of the active NI-2 card. See "NI-2 Card Cold Redundancy" section for additional information.
APS link redundancy, which provides recovery from a cut fiber or the failure of an OC-3c optical transmitter or optical receiver interface on an NI-2 card. APS redundancy is available on OC-3c/2DS3 NI-2 card trunk interfaces and OC-3c/OC-3c NI-2 card trunk and subtend interfaces. See "APS Link Redundancy" section for additional information.

Note Line card redundancy is not supported.

NI-2 Card Cold Redundancy

NI-2 card cold redundancy requires that two NI-2 cards be installed in the chassis. The primary card is installed in slot 10 of the chassis, and the secondary card is installed in slot 11. Either the primary or the secondary NI-2 card can serve as the active NI-2 card. The interface types must be the same for both the primary and secondary NI-2 cards. See Table 2 for a list of NI-2 cards that support cold redundancy and information about NI-2 card and chassis compatibility.

During steady-state operations, one NI-2 card functions as the active unit, and the other functions as the standby unit. The active NI-2 card displays a green ACTIVE LED. In an active state, the NI-2 card

Has full Ethernet, auxiliary port, and console access
Communicates with line cards
Has full access to the environmental monitoring subsystem
Has access to the optical interfaces on the standby NI-2 card
Allows remote access to the file system of the standby NI-2 card

The standby NI-2 card plays a minimal role during steady-state operations. In a standby state, the NI-2 card

Receives configuration changes from the active NI-2 card (when the cards are configured for synchronization)
Has no Ethernet, auxiliary port, or console access
Does not communicate with line cards
Has no access to the environmental monitoring subsystem
Generates only APS alarms, which are reported via the active card

For management purposes, the primary and secondary NI-2 cards appear as one element. The cards share one IP address.

Note For information on NI-2 card cold redundancy switchover conditions, refer to the Upgrading DSLAMs for NI-2 Card and APS Link Redundancy document.

Due to the differences in bootflash between the commercial OC-3c/OC-3c NI-2 card (NI-2-155SM-155SM and NI-2-155SM-155MM) and the version of the OC-3c/OC-3c NI-2 card with enhanced upstream bandwidth features (NI2-155SM-155SM2 and NI2-155MM-155MM2), the NI2 redundancy feature of syncing the bootflash with the secondary sync bootflash command and the auto-sync configuration bootflash command are not supported.

APS Link Redundancy

APS link redundancy provides recovery from a cut fiber or the failure of an OC-3c optical transmitter or receiver interface on an NI-2 card. APS link redundancy is available on OC-3c/2DS3 NI-2 card trunk interfaces and OC-3c/OC-3c NI-2 card trunk and subtend interfaces.

The working link is the fiber connection between the ATM switch and the primary NI-2 card installed in slot 10 of the chassis. The protection link is the fiber connection between the ATM switch and the secondary NI-2 card installed in slot 11 of the chassis. When the fiber or optical ports on the active NI-2 card fail, that card remains active, but uses the corresponding fiber or optical ports on the standby NI-2 card.

APS protocol information is carried over the protection link connected to the secondary NI-2 card in slot 11. The standby NI-2 card continually reports Synchronous Optical Network (SONET) state information to the active NI-2 card.

APS link redundancy is nonrevertive. For example, after a switchover from the working to the protection link occurs, the active NI-2 card switches back to the working fiber only if manually forced through a CLI command or if a failure condition occurs on the protection link. However, if a failure condition occurs on the protection link while the working link is still in a failed state, a switch back to the working link does not occur.

Note For information on APS link redundancy switchover conditions, refer to the Upgrading DSLAMs for NI-2 Card and APS Link Redundancy document.

Redundancy in Subtended Configurations

NI-2 card redundancy is supported in a DS3 subtend tree or in an OC-3c subtend daisy-chain if both the subtending host chassis and the subtended node chassis have primary and secondary NI-2 cards installed. An NI-2 card failure on a node in a subtend tree or daisy-chain temporarily interrupts traffic to all subtended node chassis.

APS link redundancy is supported in subtending configurations only if the subtending host chassis has a secondary (redundant) OC-3c/OC-3c or OC-3c/2DS3 NI-2 card installed.

Note For more information about subtending and subtended network configurations, refer to the appropriate hardware installation guide.

General Maintenance Guidelines

This section covers the following topics:

Installation and Replacement Suggestions

The following examples list recommended installation and replacement practices for the NI-2 cards.

Caution Any card that is only partially connected to the backplane can disrupt system operation.

Do not force the card into its slot. This action can damage the pins on the backplane if they are not aligned properly with the card.
Ensure that the card is straight and not at an angle when you install the card in the slot. Installing the card at an angle can damage the card. Use the guide rails to install the card correctly.
Firmly seat the card in the slot. Fully depress the ejector levers to ensure that the card connector mates with the backplane correctly.

Hot Swapping Cards

The NI-2 card can be hot swapped. Hot swapping allows you to remove and replace the cards without disconnecting the system power. When the system detects that you have added or removed a card, it automatically runs diagnostic and discovery routines and acknowledges the presence or absence of the card.

Preventing Electrostatic Discharge Damage

Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Use an antistatic strap when you handle any card or component.

Follow these guidelines to prevent ESD damage:

Always use an ESD ankle or wrist strap and ensure that the wrist strap makes good skin contact.
Connect the equipment end of the strap to the ESD jack on the chassis.
When you install a component, use available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
When you remove a component, use available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
Handle the I/O card or I/O module by the edges only; avoid touching the printed circuit boards or connectors.
Avoid touching the printed circuit boards or connectors on the NI-2 cards or line cards.
Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.
Avoid contact between the printed circuit boards and clothing. The ankle or wrist strap protects components from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

Caution Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1 and 10 megohms.

Removing and Installing IMA NI-2 Cards

The following sections describe how to remove and install a DS3+T1/E1 IMA NI-2 card or an ITEMP DS3+T1/E1 IMA NI-2 card.

Removing a DS3+T1/E1 IMA NI-2 Card

Complete the following steps to remove a DS3+T1/E1 IMA NI-2 card or an ITEMP DS3+T1/E1 IMA NI-2 card from the chassis.

Caution This caution applies only to the Cisco 6160 and Cisco 6260 chassis. The Cisco 6015 chassis does not support redundancy.

Service is interrupted to the entire system when the NI-2 card is removed unless a secondary NI-2 card is installed in the chassis. If a secondary NI-2 card is not installed, ensure that a service interruption is acceptable before proceeding.

If a secondary NI-2 card is installed in the chassis, removing the active NI-2 card causes a switchover to the standby NI-2 card, which interrupts data traffic for approximately 60 seconds.

Removing a standby NI-2 card does not interrupt service to the system.

Step 1 Connect a grounding strap to the ESD grounding jack.

Step 2 Disconnect the cable connected to the RJ-45 auxiliary port (AUX) on the NI-2 card, as necessary.

Step 3 Disconnect the cable connected to the system console port (CNSL) on the NI-2 card, as necessary.

Step 4 Disconnect the cable connected to the RJ-45 10BaseT receptacle (ENET) on the NI-2 card, as necessary.

Step 5 Use a flat-head screwdriver to move the locking tabs on the faceplate from the locked to the unlocked position. Be sure to turn the locking tabs so that they do not overlap the NI-2 card ejector levers, as shown in Figure 5.

Figure 5: Positioning the Locking Tab for NI-2 Card Removal and Installation

Step 6 Lift up on the ejector levers. This action disconnects the card from the backplane.

Step 7 Carefully slide the card out of the slot.

See the "Installing a DS3+T1/E1 IMA NI-2 Card" section for NI-2 card installation procedures.

Installing a DS3+T1/E1 IMA NI-2 Card

Complete the following steps to install a DS3+T1/E1 IMA NI-2 card or an ITEMP DS3+T1/E1 IMA NI-2 card in the chassis. This procedure shows how to install the NI-2 line card in the Cisco 6015 and the Cisco 6160 as examples, but the basic installation procedure is the same for other chassis and all NI-2 card types

Note All cards must be fully seated in the chassis. Push on the faceplate of each card to be sure that the card is fully seated.

Step 1 Connect a grounding strap to the ESD grounding jack.

Step 2 Inspect the NI-2 card. Verify that the daughterboard is fully seated on the main board.

Step 3 Verify that the NI-2 card slot in the chassis has no bent pins.

Step 4 Hold the NI-2 card with the faceplate toward you and the connectors facing the chassis slot.

Step 5 Align the card edges with the slot guides in the chassis.

Step 6 Lift up on the ejector levers and gently apply pressure to the faceplate while pushing the card into the slot.

Figure 6 shows an example of how to install an NI-2 card in a Cisco 6015 chassis.

Figure 6: NI-2 Card Installation in the Cisco 6015

Figure 7 shows an example of how to install an NI-2 card in a Cisco 6160 chassis.

Figure 7: NI-2 Card Installation in the Cisco 6160

Step 7 Push on the faceplate of the card to fully seat the card.

Step 8 Press down on the ejector levers to secure the card and connect it to the backplane.

Step 9 Use a flat-head screwdriver to turn the locking tabs on the faceplate so that they overlap the NI-2 card ejector levers to prevent inadvertent dislodging. Figure 5 shows how to position the locking tabs.

Step 10 Verify that the STATUS, ACTIVE, and POWER LEDs on the NI-2 card are solid green after the self-test is complete. The self-test procedure takes several minutes. If the LEDs are not green after the self-test, refer to the appropriate hardware installation guide for troubleshooting procedures.

Note If you are installing the card for the first time, refer to the provisioning procedures in the Configuration Guide for Cisco DSLAMs with NI-2.

Step 11 Perform a software update if the STATUS LED on the NI-2 card is blinking.

Refer to the Configuration Guide for Cisco DSLAMs with NI-2 for software upgrade procedures.

Note The network connection to the ATM switch and the subtending connections are made from the I/O card or I/O module. For more information on these connection procedures, refer to the appropriate hardware installation guide.

Step 12 Connect the Ethernet to the management network.

a. Connect an Ethernet cable to the RJ-45 10BaseT receptacle (ENET) on the DS3+T1/E1 IMA NI-2 card faceplate.

Note See the "Required Tools and Equipment" section for cable and ferrite requirements.

An Ethernet cable connected to a DS3+T1/E1 IMA NI-2 card that is installed in a Cisco 6015 chassis must have a ferrite attached. If you are connecting an Ethernet cable to a DS3+T1/E1 IMA NI-2 card installed in a Cisco 6160 chassis, skip Step b and proceed to Step c.

b. Run the Ethernet cable through the ferrite one time and clamp the ferrite shut.

c. Connect the other end of the Ethernet cable to the management network (for example, a LAN).

Step 13 Connect a VT100-compatible terminal to the system console port (CNSL) on the NI-2 card faceplate. Connect the terminal to a power source and set it up using the values shown in Table 14.

Table 14: Terminal Settings

Baud rate	9600 (transmit and receive)
Character size	8 bits
Parity	None
Stop bits	1
Flow control	None

Step 14 Connect a terminal, a modem, or another serial device to the RJ-45 auxiliary port (AUX) on the NI-2 card faceplate. This step is optional.
