What is a 8540 DSL Card?

A Digital Subscriber Line (DSL) 8540 card is a circuit card assembly (CCA) that

contains four Rate Adaptive Digital Subscriber Line (RADSL) ports, an Ethernet

interface to the Internet Service Provider (ISP), and a processor. The processor

controls the RADSL ports and forwards the packet traffic to and from the Ethernet

and DSL interfaces. When the 8540 DSL card is used in a HotWire 8600 or 8800

DSL Access Multiplexer (DSLAM) chassis and connected to HotWire 5100/5200

series Remote Termination Units (RTU), it provides high-speed Internet or

Intranet access over traditional twisted-pair telephone wiring.

!HANDLING PRECAUTIONS FOR

STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from damage

due to electrostatic discharge (ESD) during normal operation. When

performing installation procedures, however, take proper static control

precautions to prevent damage to equipment. If you are not sure of the

proper static control precautions, contact your nearest sales or service

representative.

Intranet connectivity. Refer to the

HotWire DSLAM for 8540 and 8546 DSL

Cards User’s Guide

, Document No. 8000-A2-GB20, for more detailed

configuration procedures.

8540-A2-GN10-00 October 1997

Cables You Need

The following customer-provided cables are used with this product:

HPlug-ended Telco 50-pin cable for connection from the HotWire DSLAM Line

port to the CO POTS splitter shelf, Main Distribution Frame (MDF), or other

demarcation point.

HOne 8-pin modular UTP (Unshielded twisted Pair) CAT5 cable for each

connection from a LAN/WAN port associated with a 8540 DSL card in the

HotWire DSLAM chassis to the Ethernet hub or switch.

CAUTION:

Use of any non-twisted pair wiring arrangements, such as jumpers, can

cause reduction in overall DSL reach performance, even over short

distances. Please refer to the Special Notice shipped with the

HotWire 8800/8600 DSLAM.

Refer to

Pin Assignments

on page 9 for pinouts.

Installing 8540 DSL Cards

Use a small- to medium-size flat-blade or Phillips screwdriver to install the

8540 DSL card.

When using a . . . Install the DSL card into . . .

HotWire 8600 DSLAM base chassis Slot 2 or 3 (Slot 1 of the HotWire 8600

DSLAM base chassis must contain a

Management Communications

Controller (MCC) card.)

HotWire 8600 DSLAM expansion chassis Slot 1, 2, or 3

HotWire 8800 DSLAM chassis Any one of the first 18 slots (i.e., Slot 1

through 18)

An 8540 DSL card can be installed, removed, and replaced from a HotWire

DSLAM chassis without service disruption (i.e., you can replace a card without

powering down the chassis and disrupting service to the other cards in the

chassis).

NOTE:

When installing the 8540 DSL card, you will need to remove the filler plate

before proceeding.

Do not discard unused filler plates. Each slot in the chassis must contain a

circuit card or a filler plate. 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 an 8540 DSL card:

1. Remove the filler plate from the desired slot.

2. Insert the 8540 DSL card into this slot:

— For a HotWire 8600 DSLAM chassis – hold the 8540 DSL card

horizontally with component side facing up and insert it into the left and

right card guides.

3. Slide the 8540 DSL card into the slot until the power and network connectors

seat firmly in the mating connectors on the backplane.

CAUTION:

Do not force the 8540 DSL card into the slot. If it does not seat properly,

remove the card and reinstall it. If it still does not seat properly, call

service.

The 8540 DSL card performs a power-up self-test. All of the LEDs turn ON

and OFF briefly. When the self-test is completed successfully, the SYSTEM

OK LED will turn ON. Make sure the SYSTEM OK indicator on the DSL card

faceplate is ON (winking green).

4. If the LED is not ON, refer to the

Troubleshooting

chapter of the appropriate

HotWire DSLAM Installation Guide.

5. Secure the DSL card by fastening the screws at each end of the faceplate.

NOTE:

The 8540 DSL cards may be replaced without system disruption (i.e., you

can remove and re-install a card without powering down the HotWire DSLAM

chassis and disrupting service to the other cards). To remove an 8540 DSL

card from the HotWire DSLAM chassis, unfasten the screws on both ends of

the faceplate. Then, simply push the ejector handles outward and slide the

card out.

When swapping the old 8540 DSL card with a new 8540 DSL card, it is

important to note that the 8600 DSLAM retains the Media Access Control

(MAC) address, also referred to as the physical address. This means that the

new DSL card will have the same MAC address as the old one.

Connecting to a POTS Splitter or an MDF

You can connect the HotWire DSLAM chassis containing the 8540 DSL card to a

POTS splitter shelf, MDF, or other demarcation point.

NOTE:

If you are connecting the HotWire DSLAM to a CO POTS splitter, this

procedure assumes that the CO POTS splitter shelf is already installed. For

information on how to install the CO POTS splitter, refer to the

HotWire POTS

Splitter Central Office Installation Instructions,

Document No. 5020-A2-GN10.

"Procedure

To connect the HotWire DSLAM chassis containing the 8540 DSL card to a POTS

splitter shelf or MDF:

1. Plug the Telco 50-pin cable into the appropriate LINE port on the front panel

of the chassis:

3. Insert a cable tie (provided with HotWire DSLAM chassis) through the tie

mount to hold the Telco 50-pin connector in place. If more than one Telco

cable is being connected, replace the existing cable tie with a single tie to

span the two or three connectors.

4. Make sure the other end is connected to the appropriate POTS splitter shelf,

MDF, or demarcation point.

Refer to

Pin Assignments

on page 9 for pinouts.

NOTE:

If you are connecting the Telco 25-pair, 50-pin cable to an MDF without a

POTS splitter in the line, a converter may be necessary for terminating the

other end of the cable on a punchdown block before cross-connecting to an

MDF.

Connecting the DSL Cards to the Ethernet Hubs or Switches

"Procedure

To connect the 8540 DSL cards to the Ethernet hubs or switches:

1. Plug the end of an 8-pin modular cable into the appropriate LAN/WAN SLOT

port of the chassis. For example, if you want to connect to the LAN/WAN port

of an 8540 DSL card, insert the 8-pin modular cable in LAN/WAN Slot #2.

2. Plug the other end of the cable into your Ethernet hub or switch connector.
