Product Overview

This chapter provides an overview of the Cisco 6260 Digital Subscriber Line (DSL) Access Multiplexer
(DSLAM) and its related components, collectively known as the Cisco 6260 system. This chapter contains
the following sections:

• Introduction to the Cisco 6260 System, page 1-1

• Cisco 6260 System Overview, page 1-10

• Management Software, page 1-49

1.1 Introduction to the Cisco 6260 System

The Cisco 6260 system is part of the Cisco DSL product family that provides end-to-end service by
carrying voice or data traffic, or both, between a subscriber’s home or office, a telephone central office
(CO), and various networks beyond. The Cisco 6260 system sends and receives subscriber data (often
Internet service) over existing copper telephone lines, concentrating all traffic onto a single high-speed
trunk for transport to the Internet or a corporate intranet. Before traveling over telephone lines to the
DSLAM at the CO, data is modulated by xDSL customer premises equipment (CPE) devices, which are
connected to PCs or routers at the subscriber site.

The Cisco 6260 system may include the following components:

1.1.2.3 IMA Configuration

The DS3+T1/E1 IMA NI-2 card uses inverse multiplexing over ATM (IMA) technology to aggregate
multiple low-speed links into one larger virtual network trunk or IMA group. An inverse multiplexer
appears to your ATM switch router as one logical pipe. IMA provides you with modular bandwidth to
access the ATM network between T1/E1 and DS3/E3 rates. The Cisco 6260 system allows you to
combine up to eight E1 lines to form an IMA group.

Cisco 6260 Hardware Installation Guide

1-4

OL-2365-02

Chapter 1 Product Overview

IMA breaks up the ATM cell stream, distributes the cells over the multiple physical links of an IMA
group, and recombines the cells into a single stream at the other end of the connection. The ATM cells
are distributed in a round-robin fashion over the physical links of the IMA group, recombined at the
receiving IMA group, and passed in their original form to the ATM layer (see Figure 1-2). Using the
multiple links of an IMA group increases the logical link bandwidth to approximately the sum of the
individual link rates. The physical links should be nominally the same length to avoid excessive
intragroup delay. We recommend that all of the links in an IMA group be bundled together between the
source and the destination.

E1 I/O modules have eight ports. You can use the eight ports on the E1 I/O modules as independent ATM
links or in the IMA mode. The following bullets are examples of possible IMA groups, independent ATM
links, and mixed modes. In examples of IMA groups, two links are assumed per group.

• Four IMA groups with any combination of eight links

• Three IMA groups and up to two independent ATM links

• Two IMA groups and up to four independent ATM links

OL-2365-02

• One IMA group and up to six independent ATM links

• No IMA group and up to eight independent ATM links

The E1 (1.544 Mbps) IMA port adapters provide network trunk or subtend connectivity and are used for
intercampus or wide-area links. The E1 IMA port adapters support unshielded twisted-pair (UTP)
connectors. The order of assignment of links to an IMA group is not restricted.

The IMA group interfaces use a naming convention different from those used by the other interfaces in
the system. IMA group interfaces are named with the convention atm<slot>/ima<group>, where <slot>
is the slot number for the DS3+T1/E1 IMA NI-2 card and <group> is the IMA group number from 0 to

1.1.2.4 Subtended Network Configuration

The term subtending refers to the host chassis, and subtended refers to the downstream chassis in a
subtended network.

Note For information on enabling redundancy in subtended network configurations, see the “Redundancy in

Subtended Configurations” section on page 1-41.

A subtended network configuration

• Services and aggregates the data from one or more Cisco 6260 chassis into a subtending host chassis

to take advantage of the data network interface on the subtending host chassis.

• Reduces the number of ATM edge-switch ports required to terminate the chassis.

• Supports a Cisco 6260 system with a POTS splitter and a Cisco 6260 system without a POTS

splitter configuration.

A subtended network configuration supports the following features:

• Four arbitration priorities, one for each quality of service (QoS) level. The supported QoS service

levels are

–

Constant bit rate (CBR) for rate-limited services that require guaranteed bandwidth and
bounded delay

–

Variable bit rate real time (VBR-rt) for delay-sensitive voice and video services

1-6

–

Variable bit rate nonreal time (VBR-nrt) for high-priority data services

–

Unspecified bit rate (UBR) for low-priority data services

• Explicit forward congestion indication (EFCI) marking for available bit rate (ABR) service support.

• Guaranteed frame rate (GFR).

Chapter 1 Product Overview

• Tree or daisy chain topology configurations for E3 subtended Cisco 6260 chassis.

• Star topology configurations for E1 or IMA group subtended Cisco 6260 chassis.

• Daisy chain configurations for OC-3c subtended Cisco 6260 chassis.

• Fair access to the trunk port for each subtended chassis.

• A network trunk port that operates as fast as any subtended link.

The NI-2 card provides one of following types of subtended network connections:

• An E3 ATM interface

• A high-speed OC-3c optical ATM interface that supports single-mode fiber (SMF)

• A high-speed OC-3c optical ATM interface that supports multimode fiber (MMF) short range

• Up to eight E1 interfaces when you are using the DS3+T1/E1 IMA NI-2 card in conjunction with

• Up to four IMA interfaces when you are using the DS3+T1/E1 IMA NI-2 card in conjunction with

the E1 I/O module.

1.1.2.4.1 Subtended Network Configuration with DS3/2DS3 NI-2 Cards

In a subtended network configuration using DS3/2DS3 NI-2 cards, you can subtend a Cisco 6260
chassis to four tiers, with up to 12 chassis, all connecting through one subtending host chassis to the
ATM backbone.

When the DS3/2DS3 NI-2 card is installed in the Cisco 6260 chassis, it adopts E3 functionality.

Figure 1-3 shows E3-configured Cisco 6260 systems subtended in a combined subtending tree topology

with daisy chain. The subtending host chassis at the top of the subtending tree connects directly to the
ATM switch. The middle two Cisco 6260 chassis in the lowest level are daisy chained. You make
network interface connections at the I/O module that is installed on the front of the Cisco 6260 chassis.

For each chassis in a subtended network configuration to have fair access to the shared network trunk,
the chassis must have a unique ID number. The subtending host chassis places this ID number in the GFC
field of the ATM header of each cell; this ID number is then used to forward cells up the tree to the
network trunk.

Note You can subtend Cisco 6260 chassis with DS3/2DS3 NI-2 cards in a continuous daisy chain. However,

a daisy-chained subtending scheme is not optimal for data throughput for Cisco 6260 chassis that use
DS3/2DS3 NI-2 cards.

Cisco IOS software does not manage the primary Cisco 6260 chassis and all subtended Cisco 6260
chassis as a single large Cisco 6260 system. Each Cisco 6260 chassis supports an independent Cisco IOS
processor and MIBs.

1.1.2.4.2 Subtended Network Configuration with DS3+T1/E1 IMA NI-2 Cards

In a subtended network configuration using DS3+T1/E1 IMA NI-2 cards, you can subtend Cisco 6260
systems in a star topology. The eight E1 links can be used as network trunk or subtend interfaces or can
be combined into trunk or subtend IMA groups in the following two ways:

• E1 IMA group or E1 User-Network Interface (UNI) as the network trunk with seven subtended node

chassis

Note If you are using an E1 trunk to the network, the trunk connection originates at one of the RJ-48

receptacle connectors on the E1 I/O module. Therefore, you can have only seven subtended

1.2.3.8 Line Card Intermixing

Note Figure 1-6 shows the Cisco 6260 chassis slot numbers.

The Cisco 6260 chassis supports line card intermixing. This section uses the terms halves and quadrants.
The Cisco 6260 chassis consists of two halves:

• Slots 1 to 9 and slots 18 to 26 (left half of the chassis)

• Slots 12 to 17 and slots 27 to 32 (right half of the chassis)

The Cisco 6260 chassis consists of four quadrants:

• Slots 1 to 9 (top left quadrant)

• Slots 12 to 17 (top right quadrant)

• Slots 18 to 26 (bottom left quadrant)

• Slots 27 to 32 (bottom right quadrant)

The following sections describe the line card intermixing guidelines for the Cisco 6260.

OL-2365-02

Cisco 6260 Hardware Installation Guide

1-27

Chapter 1 Product Overview

Cisco 6260 System Overview

1.2.3.8.1 Guidelines for Intermixing xDSL Line Cards

Mixing line cards of different modulation types in the same quadrant of any Cisco DSLAM is prohibited.
Different modulation types are allowed in the same half of a chassis with the exceptions of slots 18 and
34 in the Cisco 6160 beginning with Cisco IOS release 12.2(7)DA. Mixing line cards of the same
modulation type (for example, 4xFlexiDMT and 8xDMT line cards) in a quadrant is allowed.

1.2.3.8.2 Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.1(7)DA2, 12.2(1b)DA, and 12.2(5)DA

The Cisco 6260 chassis can be fully populated with 8xG.SHDSLs while retaining QoS, as long as the
upstream bandwidth is provisioned at a maximum of 5 Mbps for even ports and a maximum of 5 Mbps
for odd ports per line card. Once an 8xG.SHDSL is installed in a chassis quadrant, no ADSL line cards
can be installed in that same quadrant.

1.2.3.8.3 Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.2(7)DA and Later

The Cisco 6260 system supports up to 16 8xG.SHDSLs installed per chassis while retaining QoS. Once
an 8xG.SHDSL is installed in a quadrant, no ADSL line cards can be installed in that same quadrant.

Figure 1-15 illustrates the optimal deployment of 8xG.SHDSLs in the Cisco 6260 chassis with quadrant

intermixing of ADSL line cards in the Cisco 6260 chassis. For example:

• If 4 8xG.SHDSLs are installed in the left side of the chassis, only 21 ADSL line cards can be

installed in the remaining chassis quadrants.

Note No ADSL line cards can be installed in the same quadrant as the 8xG.SHDSLs.

• If 4 8xG.SHDSLs are installed in the right side of the chassis, only 24 ADSL line cards can be

installed in the remaining chassis quadrants.

Note No ADSL line cards can be installed in the same quadrant as the 8xG.SHDSLs.

Caution Random cell loss may occur if the guidelines for 8xG.SHDSL deployment in a system are exceeded.

1.2.3.8.4 Guidelines for Intermixing 8xG.SHDSLs—Cisco IOS Release 12.2(12)DA and Later for NI2-155SM-155SM2 or
NI2-155MM-155MM2 Only

This section describes intermixing in Cisco IOS Release 12.2(12)DA and later for NI2-155SM-155SM2
or NI2-155MM-155MM2 only. All other NI2s, including NI2-155SM-155SM and
NI2-155MM-155MM, follow guidelines as described in the “Guidelines for Intermixing

8xG.SHDSLs—Cisco IOS Release 12.2(7)DA and Later” section on page 1-28.

The Cisco 6015, Cisco 6160, and Cisco 6260 can be fully populated with 8xG.SHDSLs while
retaining QoS.

• In the Cisco 6160 and Cisco 6260, once an 8xG.SHDSL is installed in a chassis quadrant, no other

type of line card can be installed in that same quadrant.

• In the Cisco 6015, intermixing is limited to chassis halves.

Note In order to provision 18.5 Mbps per line card in a chassis fully populated with 8xG.SHDSLs, an

OC-3c/OC-3c single-mode fiber (SMF) or multi-mode fiber (MMF) NI-2 card (NI2-155SM-155SM2
and NI2-155MM-155MM2) must be installed in the chassis.

1.2.3.12 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 is the network timing signal source, the Cisco 6260 chassis

receives a clock signal through designated pins on the I/O module and distributes the signal through
the Cisco 6260 backplane.

• An internal clock.

Cisco 6260 System Overview

alarm mode.

The Ethernet interface is active.

blinking

Off The Ethernet interface is inactive.

• E3 or OC-3c network trunk interface. An NI-2 card synchronizes with the network timing source

and provides a clock reference signal to line cards in the Cisco 6260 chassis and to subtended
node chassis.

The active NI-2 card supplies a redundant pair of clock signals to all cards in the chassis. This same
clock reference can be propagated to subtended systems via the trunk and subtended interface ports.
This is done by configuring the subtending port of the root system to source the network-derived
clock. The trunk port of the subtended system is configured as the network clock source for that
chassis. This chain continues down the subtended tree.

1.2.3.13 Redundancy Overview

Redundancy is available for the Cisco 6260 system. 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.

• Automatic protection switching (APS) link redundancy, which is available on OC-3c/OC-3c NI-2

card network trunk and subtend interfaces.

Note Line card redundancy is not currently supported in the Cisco 6260 system.

1.2.3.13.1 NI-2 Card Redundancy

NI-2 card 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. The following NI-2 cards support cold redundancy in the Cisco 6260
chassis:

OL-2365-02

Cisco 6260 Hardware Installation Guide

1-39

Cisco 6260 System Overview

• DS3/2DS3

• DS3+T1/E1 IMA

• OC-3c/OC-3c (SMF and MMF)

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

• Has no Ethernet, auxiliary port, or console access

Chapter 1 Product Overview

for synchronization)

• 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.

1.2.3.13.2 APS Link Redundancy

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

APS link redundancy is nonrevertive. After a switchover from the primary to the secondary fiber occurs,
the active NI-2 card switches back to the primary fiber only if it is manually forced through a
command-line interface (CLI) or if a failure condition occurs on the secondary fiber. However, if a
failure condition occurs on the secondary fiber while the primary fiber is still in a failed state, a switch
back to the primary fiber does not occur.

Note The OC-3c ports on the standby NI-2 card are available for APS link redundancy only if the standby NI-2

card is working and in a STANDBY-READY state.

1-40

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

OL-2365-02

Chapter 1 Product Overview

1.2.3.14 Redundancy in Subtended Configurations

NI-2 card redundancy is supported in an E3 subtend tree or daisy-chain 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.

NI-2 card redundancy is not supported in DS3+T1/E1 IMA subtended configurations.

APS link redundancy is supported in subtending configurations only if all of the following conditions
exist:

1. The subtending host chassis is configured for OC-3c/OC-3c operation;

2. The subtending host chassis has a secondary NI-2 card installed; and

3. The subtended node chassis have primary and secondary OC-3c/OC-3c NI-2 cards installed.

1.2.4 Cisco 6260 I/O Modules

This section contains the following information:

Cisco 6260 System Overview

• E3 I/O Module Overview, page 1-41

• E1 I/O Module Overview, page 1-42

• OC-3c I/O Module Overview, page 1-43

A Cisco 6260 chassis must have an I/O module installed. The I/O module is delivered installed near the
top of the Cisco 6260 chassis, just below the subscriber connectors. Figure 1-1 shows the location of the
I/O module on the Cisco 6260 chassis.

1.2.4.1 E3 I/O Module Overview

The E3 I/O module provides the Cisco 6260 chassis with a network trunk interface connector and
connectors to subtend other DSLAMs to the chassis. The E3 I/O module also provides the alarm pinouts
and BITs clock input circuits for the Cisco 6260 system.

The E3 I/O module works with the DS3/2DS3 NI-2 card in the Cisco 6260 chassis.

Note The Cisco 6260 does not support the DS3 interface. When the DS3/2DS3 NI-2 card is installed in

the Cisco 6260 chassis with an E3 I/O module, the NI-2 card adopts E3 functionality.

Figure 1-19 shows a close-up of the E3 I/O module.

1.2.4.4 I/O Module Wire-Wrap Pins

Located on the right side of each I/O module faceplate are 36 wire-wrap pins that support

• Central office alarm relay interfaces (visual and audible critical, major, and minor)

• BITS clock input circuits

• Wire-wrap and socket-type connections

Both the alarm relay and the BITS clock connections are optional. If you connect the alarm relays, they
transmit critical, major, and minor alarms to a separate, external alarm device. The alarm device uses a
bell, light, or some other signal to alert service personnel to the change in system status. If you connect
the BITS interface, the Cisco 6260 can receive a clock signal from an E1 line.

Figure 1-22 shows a close-up of the wire-wrap pins.

• Visual major alarm

• Visual minor alarm

• Audible critical alarm

• Audible major alarm

• Audible minor alarm

• Power module alarms

• Remote alarm cut off

• Reserved (several pins are reserved for future specification)

Each of the wire-wrap pins is connected to the NI-2 cards in the Cisco 6260 chassis; however, only one
NI-2 card manages the alarms. The ACO switch on the NI-2 card faceplate shuts off the audible alarms
generated by the Cisco 6260 system software.

1-44

One of the alarm relay functions provided by the wire-wrap connector is an ACO circuit that you can wire to
your external alarm device. To use this feature, connect the alarm device so that it can close the contact
between pin 5 and pin 6 in row 5.

The connector also provides contacts for the following features, all of which can be used separately:

Cisco 6260 Hardware Installation Guide

OL-2365-02

Chapter 1 Product Overview

• Audible alarms—Wire pins whose signals begin with AUD

• Visible alarms—Wire pins whose signals begin with VIS

• Power alarms—Wire pins whose signals begin with PEM

• BITS clock—Wire pins whose signals begin with RX_BITS

Note There is one set of contacts for audible alarms and one set for visual alarms. You can use either or both

sets of contacts.

You can wire the alarm relay contacts as normally open (NO) or normally closed (NC). (One exception
is the ACO circuit, which can be wired as NO only.) Use common (CO) pins for both the NO and NC
wiring methods.

1.2.5 PEM

OL-2365-02

section on page B-1.

The Cisco 6260 system is equipped with one or two –48/–60V direct current (DC) PEMs, which
distribute DC power within the chassis. The Cisco 6260 requires only one active PEM to operate; if two
PEMs are installed, the second PEM serves as a hot backup to the first.

Each PEM should be connected to a single DC power source. DC power (–48V) enters the chassis
through the terminal blocks on the front of each PEM. For full power redundancy, two PEMs must be
installed in the chassis, and the two PEMs must be connected to two separate DC power sources.

In a system with two PEMs installed, you can remove and replace each individual PEM while the system
continues to operate. (A system with a single PEM must be powered down before the PEM is removed.)

In addition, you can replace a PEM in a chassis with a single PEM installed without shutting down
system power by first removing the blank faceplate from the second slot, installing a replacement PEM
in the second slot, and then removing the first PEM. The blank faceplate can then be installed in the
empty first PEM slot.

Cisco 6260 Hardware Installation Guide

1-45

Cisco 6260 System Overview

Note The PEMs reside at the bottom of the chassis, and they are installed and accessed from the

front (see Figure 1-1 for the location of the PEM in the Cisco 6260 chassis). Each PEM is
held in place by the overhanging lip of the fan tray above it. You must remove the fan tray
before you can remove the PEM.

To turn off a Cisco 6260 that has two PEMs, you must flip the circuit breakers on both PEMs
to the OFF (0) position.

The Cisco 6260 can be ordered with only one PEM installed, and with a blank faceplate
installed in place of a second PEM.

1.2.6 Fan Tray

Note The Cisco 6260 system requires that a fan tray be installed when the system is in operation.

Cisco 6260 System Overview

Two fan trays are installed in the Cisco 6260 chassis below the line cards. Each tray houses four fans.
The compartments for the two fan trays are located side by side near the bottom of the chassis, just above the
PEMs (see Figure 1-1 for the location of the fan trays in the Cisco 6260 chassis). As you face the chassis,
fan tray 1 is on the left; and fan tray 2 is on the right.

A narrow bezel fits across the chassis to hold the air filters and fan trays in place.

Figure 1-24 shows a close-up view of the fan tray.

Figure 1-24 Cisco 6260 Fan Tray

26374

The fans have two speeds. By default, they run at low speed. The system turns up the fan speed when

• It senses high temperatures within the chassis.

• One or more fans fail.

• The other fan tray is removed.

The fan speed returns to normal (low speed) when

• Temperatures within the chassis fall to acceptable levels.

• A missing fan tray is reinstalled in the chassis.

Caution The fans in both fan trays must run continuously. The system might suffer thermal damage if the fans in either

tray stop for more than 5 minutes.

An air filter is located above each fan tray. The air filters must be removed and cleaned periodically. See
the “Replacing or Cleaning the Air Filter” section on page 6-2 for instructions on cleaning the air filters.

Note For hardware specifications for the fan tray, see the “Fan Tray” section on page A-12.

An electrostatic discharge (ESD) jack is located on the top of the chassis at the right front corner. Before
removing any components from the chassis or installing any components, ground yourself by using the
ESD jack.

OL-2365-02

Chapter 1 Product Overview

1.2.9 Third-Party POTS Splitter

For information about the third-party POTS splitter, refer to the vendor documentation.

1.3 Management Software

You can provision and manage the Cisco 6260 system through the following management software:

–

Cisco IOS—A command-line interface (CLI) that is available for network
element provisioning.

–

Cisco DSL Manager (CDM)—An element management system designed to configure and
manage the 6xxx series of Cisco IOS software-based DSLAMs through a graphical-user
interface (GUI). CDM provides the following areas of network management: fault,
configuration, performance, and security. CDM runs within the Cisco Element Manager
Framework (EMF); both are installed on Sun workstations.

Cisco EMF is based on an object model in which network elements or modules represent the
managed entity. Each object is defined by a class and specific attributes. An object can represent
a network element or a more abstract entity such as a link relationship, a network, or a container
such as a site, shelf, or region.

Management Software

Note If your network contains multiple SUN workstations, you must dedicate one workstation as the

server and use all additional workstations as clients. The server should be the repository and
distributor of database information from which the clients request information. The client
workstations allow multiple users to monitor the managed network.

1.3.1 Management Software-Generated Alarms

The Cisco 6260 includes CO alarm LED indicators and relays that indicate system status. You can wire
CO facility alarm relay contacts for either normally open or normally closed operations. The supported
alarms that are generated by the management software are:

• CRITICAL—A critical condition is indicated when the CRITICAL LED in the NI-2 card faceplate

lights.

–

When a critical alarm occurs, the critical visual and audible alarm relays are activated.

–

A critical alarm affects many or all subscribers that are connected to the node. (For example,
failure of the NI-2 card or the network trunk connection can cause a critical alarm.)

–

Critical alarms clear after you fix the condition that triggered the alarm.

–

Audible alarms are turned off when you press the ACO button on the NI-2 card faceplate or clear
the alarm in the Cisco IOS software.

• MAJOR—A major alarm condition is indicated when the MAJOR LED in the NI-2 card faceplate

lights.

OL-2365-02

–

When a major alarm occurs, the major visual and audible alarm relays are also activated.

–

Many of the subscribers that are connected to the node are affected.

–

Major alarms clear after you fix the condition that triggered the alarm.

Cisco 6260 Hardware Installation Guide

Chapter 1 Product Overview

–

Audible alarms are turned off when you press the ACO button on the NI-2 card faceplate or clear
the alarm in the Cisco IOS software.

• MINOR—A minor alarm condition is indicated when the MINOR LED in the NI-2 card faceplate

lights.

–

When a minor alarm occurs, the minor visual and audible alarm relays are also activated.

–

A small number of subscribers that are connected to the node are affected.

–

Minor alarms clear after you fix the condition that triggered the alarm.

–

Audible alarms are turned off when you press the ACO button on the NI-2 card faceplate or clear
the alarm in the Cisco IOS software.

Visual and audible alarm relay contacts can be wired from the Cisco 6260 to CO alarm devices (remote
lights or bells, for example) located anywhere within the facility.

The visual and audible alarm relays are located on the I/O module, but the NI-2 card hardware operates
them.

placing it in an antistatic bag.

Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed
circuitry could constitute an energy hazard.

2.1.3 Preventing Electrostatic Discharge Damage

Proper electrostatic discharge (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 during handling.

Follow these guidelines to prevent ESD damage:

• Always use an ESD ankle or wrist strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to the ESD jack on the top of the chassis at the right

front corner.

• 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 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 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.

Safety Requirements

2.1.4 General Maintenance Guidelines

This section covers the following topics:

• Hot Swapping Cards, page 2-10

• Hot Swapping I/O Modules, page 2-10

• Installation and Replacement Suggestions, page 2-11

2.1.4.1 Hot Swapping Cards

Hot swapping allows you to remove and replace cards without disconnecting the system power. The
Cisco 6260 chassis supports hot swapping for the following cards:

• Quad-port DMT ATU-C (4xDMT)

• Quad-port DMT ATU-C over ISDN (4xDMT over ISDN)

• Quad-port flexi ATU-C (4xflexi)

• Quad-port STU-C (4xSDSL)

Chapter 2 Preparing for Installation

• Octal-port DMT ATU-C (8xDMT)

• Octal-port DMT ATU-C (8xDMT over ISDN)

• Octal-port G.SHDSL SHTU-C (8xG.SHDSL)

When the system detects that you have added or removed a line card, it automatically runs diagnostic
and discovery routines and acknowledges the presence or absence of the line card. If you remove and
replace a line card with one of the same type, the newly installed line card receives the same provisioning
as the original card. The system resumes operation without any operator intervention.

Note Hot swapping line cards interrupts service for the subscribers assigned to that line card.

The Cisco 6260 also supports hot swapping for the DS3/2DS3 and OC-3c/OC-3c NI-2 cards. Hot
swapping active NI-2 cards interrupts service for the entire system until the NI-2 card is replaced or until
a redundant NI-2 takes over system operations. However, you can hot swap standby NI-2 cards without
interrupting service.

2.1.4.2 Hot Swapping I/O Modules

Hot swapping allows you to remove and replace an I/O module without disconnecting the system power.
The Cisco 6260 chassis supports hot swapping for the I/O module, but removing the I/O module
interrupts the service for the entire system until it is replaced.

2-10

Caution The I/O module must be installed and replaced by a trained technician only.

Cisco 6260 Hardware Installation Guide

OL-2365-02

Chapter 2 Preparing for Installation

2.1.4.3 Installation and Replacement Suggestions

The following are recommended installation and replacement practices for the Cisco 6260 system cards
and modules.

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

• Do not force the line 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.

• Fully depress the ejector tabs to ensure that the card connector mates with the backplane correctly.

Firmly seat the card in the slot by locking the card.

• Ensure that the I/O module is straight and parallel to the top of the chassis when you attach the

module to the chassis. The pins on the connectors can be damaged if the module is not
installed correctly.

2.2.2 Power Requirements

The CO power source or rectifier supplies external power to the system as –48V direct current (DC) from
the fuse and alarm panel. Power connections from the fuse and alarm panel are wired separately to the
Cisco 6260 chassis. Connections for single- and dual-power feeds are provided. The power input
connections are redundant, and only one is required for system operation. The nominal voltage is –48
VDC; the minimum operating value is –36 VDC; and the maximum operating value is –60 VDC.

Caution Before you connect the system to a power source, verify that the power source is properly grounded and

that it falls within the internal power supply rating.

The typical power required for your Cisco 6260 system will depend on your configuration type. Use

Table 2-3 to calculate the power required for each of the Cisco 6260 system components and the total

power required for the system.

2.2.3 Rack-Mounting Requirements

We recommend that you mount the Cisco 6260 system in a rack. Ensure that vertical hole spacing on the
rack rails meets standard EIA-310-C or ETS300 requirements—1 inch (2.54 cm) spacing.

The Cisco 6260 fits into a 19-inch wide rack, or an ETSI 600-mm-wide (23-inch-wide) rack or cabinet.

Warning

Warning

Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with
both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:

—This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

—When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.

—If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing

3.2 Installation Procedures

The following sections detail the installation procedures for a Cisco 6260 with a POTS
splitter configuration.

3.2.1 Measure Rack Space

For the rack to remain stable, you must install your Cisco 6260 system from the bottom to the top of the
rack.

Before you install any of the chassis, measure the total rack space required to install your system. The
required rack space depends on the number of Cisco 6260 chassis and third-party POTS splitters that you
plan to use. The number of chassis increases if you plan to install a subtended network.

Note See Chapter 2, “Preparing for Installation,” to determine the total rack space you need for your

configuration.

Installation Procedures

Warning

Warning

Warning

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
precautions to ensure that the system remains stable. The following guidelines are provided to ensure
your safety:

—This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

—When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.

—If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing
the unit in the rack.

Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with
both hands. To prevent injury, keep your back straight and lift with your legs, not your back.

Never attempt to lift the chassis with the handles on the power supplies, fan trays, or the switching
modules. These handles are not designed to support the weight of the chassis. Using them to lift or
support the chassis can result in severe damage to the equipment and serious bodily injury.

If you plan to expand your system to include more chassis in the future, allow space in the rack for
additions, keeping in mind the weight distribution and stability of the rack.

3.2.2 Install the Third-Party POTS Splitter

The third-party POTS splitter is installed directly below the Cisco 6260 chassis in the rack.

Refer to the appropriate vendor documentation for installation procedures for the third-party
POTS splitter.

Step 4

Push the chassis back into the rack.

Step 5 Using a Phillips-head screwdriver, screw the ear brackets on the chassis to the rack. Use two screws at the

top of each ear bracket and two at the bottom (four screws per bracket). For stability, make sure you use at
least one round hole at each end of each bracket (the ear brackets have both round and oval holes).

Step 6 Repeat Step 1 through Step 5 for each Cisco 6260 chassis that you are installing.

3.2.5 Install Blank Faceplates

Blank faceplates should occupy any empty slots in the Cisco 6260 chassis. Blank faceplate installation
is similar to line card installation.

Cisco 6260 Hardware Installation Guide

OL-2365-02

Chapter 3 Installing a Cisco 6260 with a POTS Splitter Configuration

Complete the following steps to install blank faceplates in the Cisco 6260:

Step 1 Connect a grounding strap to the ESD grounding jack that is located on the top right of the front of the

Cisco 6260 chassis.

Step 2 Vertically align the blank faceplate edge with the guides at the top and bottom of the slot.

Step 3 Lift up on the ejector tab and gently apply pressure to the bottom of the faceplate while pushing the blank

faceplate into the slot.

Step 4 Push on the faceplate to fully seat the blank faceplate.

Step 5 Press down on the ejector tab to secure the faceplate.

3.2.6 Ground the Cisco 6260

Complete the following steps to connect the grounding lug on the Cisco 6260.

Installation Procedures

Warning

When you are installing the unit, the ground connection must always be made first and disconnected
last.

Warning

Before connecting or disconnecting ground or power wires to the chassis, ensure that power is
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel
board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch
handle of the circuit breaker in the OFF position. Use a voltmeter to test for 0 (zero) voltage at the
power terminals on the chassis.

Step 1 Ensure that power in the direct current (DC) circuit is off.

Step 2 Remove all paint or oxidation from the rack at the point of the grounding connection.

Step 3 Measure enough wire to connect the Cisco 6260 to the rack. Use 10 American Wire Gauge (AWG) green

or green with yellow stripes wire to ground the Cisco 6260 chassis.

Note Use only as much wire as is necessary to make the connection.

Step 4 Use a wire stripping tool to remove the covering from the end of the grounding wire. The manufacturer

of the grounding lug might have a specific recommendation about the length of wire to be stripped.

Step 5 Insert the stripped end of the grounding wire into the open end of the grounding lug. Be careful not to

leave any wire strands outside the lug.

OL-2365-02

Step 6 Use the crimping tool to compress the lug onto the wire.

Step 7 To verify the quality of the crimp, inspect it and tug gently on the wire.

Step 8 Locate the three grounding holes on the Cisco 6260 side panel. (See Figure 3-4.)

Step 9 Match the holes in the grounding lug to the appropriately spaced pair of grounding holes on the side of

the chassis. Use the top two holes for a 5/8-inch lug, as shown in Figure 3-4. Use the bottom two holes
for a 3/4-inch lug.

Chapter 3 Installing a Cisco 6260 with a POTS Splitter Configuration

Installation Procedures

3.2.8 Connect the Cisco 6260 to the Third-Party POTS Splitter

Refer to the appropriate vendor documentation for cabling procedures for the third-party POTS splitter.

3.2.9 Connect the Third-Party POTS Splitter to the MDF or to the Cross Connect

Refer to the appropriate vendor documentation for procedures for connecting the POTS splitter to the
MDF or to the cross connect.

3.2.10 Attach Cisco 6260 Power Connections

External power is supplied to the system as –48 VDC from the central office (CO) power source or
rectifier to the fuse and alarm panel. Power is fed from the fuse and alarm panel to receptacles in terminal
blocks located on the power entry modules (PEMs) installed in the Cisco 6260 chassis.

Connect the power connections on each PEM to separate power sources to achieve full power redundancy. If
you do not require power redundancy, use the terminals on a single PEM, or connect both PEMs to a single
power source.

Complete these instructions to connect the Cisco 6260 system to a –48 VDC power source. Ground the
chassis before you attempt this procedure, as described in the “Ground the Cisco 6260” section on

page 3-7.

Note See Chapter 2, “Preparing for Installation,” for the calculation tables that you need to determine the

minimum power requirements for your system.

Caution To prevent the system from powering up, do not install the fuses at this time. If the fuses are already

installed in the fuse and alarm panel, remove them. You can replace the fuses after the system is installed
and connected.

Follow these instructions to attach the power connections to the Cisco 6260 PEM:

Step 1 Verify that power in the DC circuit is off.

Warning

Before connecting or disconnecting ground or power wires to the chassis, ensure that power is
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel
board that services the DC circuit, switch the circuit breaker to the OFF (0) position, and tape the
switch handle of the circuit breaker in the OFF (0) position. Use a voltmeter to test for 0 (zero) voltage
at the power terminals on the chassis.

OL-2365-02

Step 2 Connect a grounding strap to the ESD grounding jack that is located on the top right of the front of the

Cisco 6260 chassis.

Step 3 Prepare the wire for the Cisco 6260 power and grounding connections, as follows:

a. Measure enough wire (6 to 10 AWG multistranded copper wire) to connect each of the PEM power

connections to the fuse and alarm panel, as well as enough to connect the grounding receptacle on
the PEM terminal block to the grounding connection at the DC power source.

b. Cut the ends of the power and ground wires so that the ends are straight, not slanted.

c. Measure 0.43 inch (11 mm) up from the end of each power and ground wire and place a mark at that

point. These are the wire ends that will be connected to the Cisco 6260.

d. Use the wire stripping tool to remove 0.43 inch (11 mm) of the covering from both ends of each

wire. Trim the ends of the covering so that they are straight, as shown in Figure 3-5, not slanted.

Figure 3-5 Strip and Square Off Power and Ground Wires

0.43 in.
(11 mm)

26689

Warning

Remove the covering from exactly the specified length of each power wire. If you strip too much of
the covering, exposed wire protruding from the terminal block will create an electrical hazard. If you
strip too little of the covering, the wire may not make a good contact with the terminal, or it may not
be held securely in place in the terminal block.

Step 4 Use a flat-head screwdriver to turn all three screws on the terminal block counterclockwise to open the

terminal connectors: + (positive), – (negative), and ground. This step ensures that the correct opening is
presented for the wires, as shown in Figure 3-6.

Step 8 Make sure that the other end of the grounding wire is connected to ground at the DC power source.

Step 9 If you are connecting two power sources to the Cisco 6260 system, repeat Step 2 through Step 8 for the

second PEM.

Warning

Only a DC power source that is isolated from the AC main power source with reinforced insulation,
and that complies with the other safety extra-low voltage (SELV) requirements in UL1950, CSA 950 3rd
Edition, EN 60950, and IEC950, can be connected to a Cisco 6260 system. This requirement ensures that
in a catastrophic power source fault condition, hazardous voltages are not present on power
terminals and connectors.
