The 8610 DSLAM accepts the following types of cards:

H Management Control Processor (MCP). This is a processor card that administers

and provides diagnostic connectivity to the DSL cards. It acts as a mid-level manager and works in conjunction with an SNMP network management system, such as HP OpenView, via its LAN port. It gathers operational status for each of the DSL cards and responds to the SNMP requests. It also has a serial port for local terminal access.

H MVL, RADSL and DSL cards. These cards provide a processor and an Ethernet

interface to the NSP. The processor controls the modems and forwards the packet traffic to and from the Ethernet and DSL interfaces. Models include:

— 8310 4-port and 8312 12-port Multiple Virtual Lines (MVL) cards that

interoperate with the Hotwire 6310 modem.

— 8510 Rate Adaptive Digital Subscriber Line (RADSL) card that interoperates

with the 5620 Remote Termination Unit (RTU).

— 8540 Digital Subscriber Line (DSL) card that interoperates with either the 5216

or 5246 Remote Termination Unit (RTU).

— 8546 DSL card that interoperates with the 5446 RTU.

H Multirate High-bit-rate Digital Subscriber Line (M/HDSL) card. H Multirate Symmetric Digital Subscriber Line (M/SDSL) card.

NOTE:

RADSL, MVL, M/HDSL and M/SDSL cards are generically referred to as DSL cards in this document.

Hotwire 8610 DSLAM Features

The Hotwire 8610 DSLAM chassis has the following features:

H Power Redundancy

Two versions of the Hotwire 8610 DSLAM chassis are available:

— ac power — dc power

The ac version can also be connected to a dc source to provide power redundancy. When using the dc version, two separate dc sources may be employed to provide power redundancy . If one power source fails, the other source provides all of the power needed by the system. This is done automatically without system disruption.

The dc version requires a source of –48 Vdc, while the ac version will operate from 100 to 250 volts ac, 50 to 60 Hz.

Page 6

H Stackable Chassis for DSL Access Growth

Each chassis is an independent, standalone system. The 8610 and 8600 chassis are interoperable in a stack. The stackable design provides for six systems to share management access through a single MCP card (for 8610) or MCC card (for

8600) which, in turn, allows an additional slot for a DSL card in each of up to five additional systems. In a stacked configuration, the first or base chassis is equipped with an MCP/MCC card in Slot 1 leaving Slots 2 and 3 available for up to two DSL cards.

Each additional system will accept up to three DSL cards. A Hotwire 8610 or 8600 DSLAM chassis can be added or removed from the stack

without disrupting data service to the other items in the stack. However, management service will be disrupted.

The base system is connected to additional systems by connecting the 8-pin modular expansion cable provided from the OUT port of the base chassis to the IN port of the next chassis in the stack.

H Hot Swappable Cards

The MCP and DSL cards can be installed and removed from the Hotwire 8610 DSLAM chassis without service disruption. You can replace a card without powering down the chassis and disrupting service to the other cards.

H Primary Network Management Support via SNMP

SNMP management of the DSL cards is accomplished over a single Ethernet connection to the MCP card from a Network Management System (NMS) (such as Paradyne’s DCE Manager for HP OpenView). The MCP card gathers all management information for each of the DSL cards and responds to the SNMP requests on behalf of the cards.

For a list of specific management information bases (MIBs) supported, see the appropriate Hotwire DSLAM Network Configuration Guide.

8610

The Hotwire 8610 DSLAM consists of the following components:

H Hotwire 8610 DSLAM base chassis

Hotwire 8610 DSLAM is a 3-slot chassis designed to house one MCP card in the first slot and up to two DSL cards in the remaining slots. Since the MCP card in the 8610 system can provide management connectivity for up to five other 8610 DSLAMs, these other systems can use the first slot for a DSL card, thus housing up to three DSL cards.

H One Management Control Processor (MCP) card

The Hotwire 8610 DSLAM requires one MCP card mounted in Slot 1 of the base, or first, chassis in a stack. The MCP card is a processor card that administers and provides diagnostic connectivity to DSL cards in from one to six 8610 DSLAMs. It acts as a mid-level manager and works in conjunction with an SNMP network management system, such as HP OpenView, via its LAN port. It gathers operational status for each of the DSL cards and responds to the SNMP requests. It also supports a serial port for local terminal access.

H At least one Digital Subscriber Line (DSL) card

The 8610 DSLAM requires at least one DSL card. Each DSL card contains a number of DSL ports (depending on model), Ethernet interface circuitry , and a processor. The processor controls the modems and forwards the packet traffic to and from the Ethernet and DSL interfaces.

Preinstallation Considerations

Consider the following before performing installation of the 8610 chassis:

H Installation Site

Your installation site should be well ventilated, clean, and free of environmental extremes. If you are installing the Hotwire 8610 DSLAM chassis in a central office rack, make sure there is 2 to 3 feet of clearance at the front of the rack in which the 8610 chassis is to be installed to allow access for the installation of the chassis, circuit cards, and cables. Also allow for proper clearance at the rear of the chassis for cabling, if using the rear cable connectors.

H Power

The ac power version requires a power source of 100–250 Vac @ 50–60 Hz; maximum current draw is 3 amps @ 1 10 Vac.

The dc power version requires a –48 Vdc power source (–40.0 to –60.0 Vdc; maximum current draw is 2 amps). The size of power source wires must be between 14 AWG and 18 A WG, and can be either solid or stranded. However, 16 AWG stranded wire is recommended.

H Grounding

A ground lug is located at the lower right of the cover at the rear. It accepts 14 AWG wire.

A noninsulated banana jack is located at the left front side of the unit to provide a ground for the ESD wrist strap plug.

H Stacking

Up to three 8610 chassis may be physically stacked safely on top of each other. However, for stacks of more than three, start a second stack or mount in a 19- or 23-inch rack. Contact your sales representative for ordering information.

H Cabling

Use only CAT3 or better twisted-pair network connection cables for DSL Termination Unit connections and interface patch cabling. Untwisted analog cables of any length anywhere in the loop substantially contribute to crosstalk and reduced loop reach.

The following customer-provided cables and cable adapters are required with this product:

— Plug-ended Telco 50-pin cable for connection from the Hotwire 8610 DSLAM

Line ports to the CO POTS splitter shelf or MDF, one cable per DSL card.

— 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection to

the DSL 10BaseT Ethernet ports. You will need this cable for accessing the LAN/WAN circuits of each DSL card.

— 8-pin UTP CA T5 modular cable for connection from the Hotwire 8610 DSLAM

MANAGEMENT MCP port to a 10BaseT hub connector (connected to an SNMP management system network) for Slot 1 in the base chassis. For other chassis in a stack, use this cable for daisy chaining the chassis together. For M/HDSL and M/SDSL cards, refer to the appropriate card Installation Instructions for the correct cable needed.

Page 9

— 14-foot serial cable and DB25 and DB9 adapters are shipped with the MCP

card. For connection to a modem, you will need a NULL modem adapter.

If there is adequate maintenance space at the rear of the rack, mount the chassis on the rack before installing cables. If there is inadequate space to do this, install the rear-mounted network connectors on the chassis before mounting the chassis on the rack.

CAUTION:

Use of any nontwisted pair wiring arrangements, such as jumpers, can cause reduction in overall DSL reach performance, even over short distances.

NOTE:

Each Hotwire 8610 DSLAM chassis weighs approximately nine pounds (with circuit cards) and can be easily installed by one installer.

Unpacking the Hardware

When shipped, the Hotwire 8610 DSLAM chassis is packed in a cardboard shipping container. Carefully remove the 8610 chassis from its shipping container and check for physical damage. If the 8610 chassis shows signs of shipping damage, report this immediately to your shipping and sales representatives.

Package Contents

The Hotwire 8610 DSLAM chassis, as shipped, consists of the following:

H Three filler plates installed in Slots 1, 2, and 3. H ac power cord (if your chassis has the ac power option) H Two reversible mounting brackets (for 19- and 23-inch rack mounting) H Associated hardware bundled in a plastic bag:

Supplying Power

The Hotwire 8610 DSLAM chassis is available in two versions:

H dc power (–40.0 to –60.0 Vdc; maximum current draw is 2 amps)

— The dc version has two separate dc inputs, A and B, to provide power

redundancy.

H ac power (100–250V; 50–60 Hz; maximum current draw is 3 amps @ 110 Vac)

— The ac version can provide power redundancy if a separate –48 Vdc source is

connected to the B input terminal.

CAUTION:

It is recommended that the following procedures be performed by a qualified electrician.

Using a Single DC Power Source

" Procedure

To supply –48 Vdc power to the 8610 chassis from a single –48 Vdc power source:

Make sure that the dc power source wires are not powered (i.e., the circuit breakers are open).

The ends of the power source wires (14–18 AWG solid or stranded wire) must be stripped of insulation. If the wires are not stripped, strip the tip of each wire (about 1/2-inch in length) before inserting the wire into the appropriate terminal on the –48V input terminal block. Ensure that each wire is fully inserted into the terminal (until it can go no further).

1. Insert the following wires into Terminal A and securely fasten each wire by tightening the screw above it. The insulation should be fully within the terminal block and no bare wire should be exposed outside of the block.

NOTE:

You should clearly label these power source wires as –48V and RTN respectively.

Insert Power Source A’s . . . Into the . . .

Negative side of the power source –48V A input terminal. Positive side of the power source RTN A (return) terminal.

Page 21

When swapping a new card for an old card, it is important to note that the 8610 DSLAM retains the Media Access Control (MAC) address, also referred to as the physical address. This means that the new card will have the same MAC address as the old one.

NOTES:

— All standalone 8610 chassis (i.e., chassis that are not daisy-chained to other

Hotwire 8610 DSLAM chassis) require an MCP card in Slot 1, but only the base chassis of a multisystem stack requires an MCP card.

— Do not discard filler plates. Each slot in the chassis must contain a circuit card

or a filler plate to maintain the required EMI shielding and to prevent air leakage from the forced air cooling. Air leakage could result in overheating which may cause the power to the circuit cards to be shut off. Store all unused filler plates in a safe place. You may need to use the filler plates to cover open slots in the chassis at a later time.

" Procedure

To install a circuit card in the Hotwire 8610 DSLAM chassis:

1. Remove the filler plate from the slot by unscrewing the mounting screws at each end.

2. Hold the card horizontally with the components on top, and insert it into the left and right card guides of the slot of the base chassis.

Verifying the Installation

To verify the hardware installation, observe the following indicators:

H The PWR A and/or PWR B LEDs on the front panel must be in the ON state

(green):

— If you are using a single –48 Vdc power source, then only the green

PWR A LED will be ON.

— If you are using dual Vdc power sources, then both the green PWR A and

PWR B LEDs will be ON.

— If you are using a single ac power source, then the green PWR A LED must

be ON.

— If you are using both an ac power source and a –48 Vdc power source, then

both the PWR A and PWR B LEDs must be ON.

H The yellow FAN ALM LED on the front panel must be OFF. H Also check the SYSTEM LEDs on the MCP and DSL cards if you have not done so

already. The OK SYSTEM indicators on the cards must be in the ON state (winking green).
