Introduction

The Hotwire 8620 GranDSLAM

The Hotwire® 8620 GranDSLAM™, which is designed to be installed in an Internet
Service Provider (ISP) or Network Access Provider (NAP) location, is a
low-startup-cost alternative chassis to the Hotwire 8820 GranDSLAM chassis. The
8620 GranDSLAM can also be placed in a Remote Terminal (RT) adjacent to the
Telco’s Digital Loop Carrier (DLC) systems. It provides high-speed Internet or
intranet access.

The System Interface Module (SIM) is shipped with the chassis already installed in
the bottom slot. The SIM provides user interface connections on the front of the
GranDSLAM.

An Asynchronous Transfer Mode (ATM) backplane provides ATM aggregation
across multiple DSL port cards.

With Release 3.0 of the GranDSLAM, there are two configurations:

n SCM-based. A Management Control Processor (MCP) card is installed in

Slot 1 for management of the DSL cards. A Shelf Concentration Module
(SCM), installed in Slot A, provides aggregation of DSL traffic for the chassis.
The chassis supports up to two DSL cards and 48 ports.

n SCP-card-based. A Shelf Concentration and Processing (SCP) card is

installed in Slot A to provide the management functions of the MCP and the
aggregation functions of the SCM. The chassis supports up to three DSL
cards and 72 ports.

The SCP card supports Models 8955, 8965, and 8985 ATM line cards. With an
MCP installed, legacy TDM cards (Models 8775, 8777, 8779, and 8799) are
also supported.

The following illustration shows a high-level view of a typical Hotwire configuration.

Hotwire 8620 GranDSLAM F ea tures

The Hotwire 8620 GranDSLAM chassis has the following features:

n AC and DC Powered Models

Two versions of the Hotwire 8620 GranDSLAM chassis are available:
— AC powered. The AC version will operate from 100 to 240 volts AC

(nominal), 50 to 60 Hz. It can also be connected to a DC source to provide

power redundancy.

— DC powered. The DC version requires a source of 48 VDC. 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.

n Hot Swappable Cards

The MCP and DSL cards can be installed and removed from the Hotwire 8620
GranDSLAM chassis without service disruption. You can replace these cards
without powering down the chassis and disrupting service to the other cards.
Removing the SCM card disrupts traffic on DSL port cards.

n Primary Network Management Support via SNMP

SNMP management of the DSL cards is accomplished over a single external
Ethernet or inband management connection to the MCP card from a Network
Management System (NMS) (such as Paradyne’s OpenLane). 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, visit
the Paradyne website www.paradyne.com. Select Support

1-5

1. Introduction

1-6 July 2003 8620-A2-GN20-40

Installation

Preinstallation Considerations

Consider the following before performing installation of the Hotwire 8620
GranDSLAM chassis:

n Installation Site

Your installation site should be well ventilated, clean, and free of
environmental extremes. If you are installing the Hotwire 8620 GranDSLAM
chassis in a central office (CO) rack, make sure there is a clearance of 2 to 3
feet at the front of the rack to allow access for the installation of the chassis,
circuit cards, and cables. If you intend to use the rear cable connectors, allow
for sufficient clearance at the rear of the chassis for cabling.

2

n Power

The AC power version requires a power source of 100–240 VAC (nominal) at
50–60 Hz; maximum current draw is 4 A at 120 VAC.

The DC power version requires a 48 VDC power source (48 VDC, nominal;
maximum current draw is 5 A). The size of power source wires must be
between 14 AWG and 18 AWG, and can be either solid or stranded. However,
14 AWG stranded wire is recommended.

n Grounding

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

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

8620-A2-GN20-40 July 2003 2-1

2. Installation

n 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 8620

GranDSLAM Line ports to the CO POTS splitter shelf or MDF, one cable

per DSL card.
— 8-pin UTP CAT5 modular cable for connection from the Hotwire 8620

GranDSLAM MANAGEMENT MCP port to a 10/100 BaseT hub connector

(connected to an SNMP management system network) for Slot 1 in the

base chassis. For TDM SDSL and TDM SHDSL cards, refer to the

appropriate card Installation Instructions for the correct cable needed.
— A 14-foot serial cable and DB25 and DB9 adapters are shipped with the

MCP card. For connection to a modem, you need a null modem adapter.
If there is limited work space behind the rack, install any rear-mounted

network connectors on the chassis before mounting the chassis in the rack.

CAUTION:

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

NOTE:

The Hotwire 8620 GranDSLAM chassis weighs 15 to 18 pounds (depending
on model) and can be easily installed by one installer.

2-2 July 2003 8620-A2-GN20-40

Hotwire 8620 GranDSLAM Chassis Installation

The Hotwire 8620 GranDSLAM chassis is designed to be placed on a desktop or
table, or mounted in a 19-or 23-inch rack (front or center mount). Installable feet
are provided for desktop or table installations. Mounting brackets are provided for
mounting in 19- or 23-inch racks.

NOTE:

Do not attach the rubber feet to the chassis if you plan to install it in a rack.
The rubber feet will cause the chassis to exceed 3U in height, limiting the
maximum number of chassis that can be installed in a rack.

You will need a large flat-blade screwdriver and a Phillips screwdriver to install the
8620 chassis.

Placing the 8620 Chassis on a Desktop or Table

2. Installation

Procedure

To install the 8620 chassis on a desktop or table:

1. Make sure that the bottom of the chassis is clean so that rubber feet will stick
to its surface.

2. Invert the chassis on a protected surface (to avoid scratching the paint).

3. Remove the protective backing from one of the rubber feet and place it in a
corner about 1/2 inch (1.27 cm) from each of the edges of the chassis,
pressing down firmly to ensure proper bonding.

4. Repeat Step 3 for each of the remaining three feet.

5. Turn the chassis right side up and place on a flat surface where desired.

8620-A2-GN20-40 July 2003

2. Installation

Rack Mounting the 8620 Chassis

The Hotwire 8620 GranDSLAM is supplied with two sets of mounting brackets,
one set for a 19-inch rack and one set for a 23-inch rack. You will only need to
install one set of brackets, depending on the type of rack into which you will be
installing the Hotwire 8620 GranDSLAM. To mount the 8620 chassis in either a
19-inch or 23-inch rack, you must first attach the proper mounting brackets to the
chassis, then install the chassis in the rack. The unused set of brackets can be
used as a template to ensure that the correct mounting holes in the rack have
been selected.

Attaching the Mounting Brackets

Procedure

To attach mounting brackets to the 8620 chassis for rack mounting:

1. Determine whether you will be front-mounting the chassis or using the 5-inch
(12.7 cm) setback.

2. Install the mounting brackets on the 8620 chassis by removing the two front
(for front-mounting) or two middle screws (for 5-inch setback) on each side of
the unit.

— For a 19-inch rack installation, use the mounting brackets with the small

flanges supplied for a 19-inch rack.

— For a 23-inch rack installation, use the mounting brackets with one small

and one large flange supplied for a 23-inch rack.

3. Secure the mounting brackets to the 8620 chassis by using the #8-32 Phillips
flat-head screws shipped in a plastic bag with the unit.

2-6 July 2003 8620-A2-GN20-40

Installing the 8620 Chassis in a Rack

Procedure

To install the 8620 chassis in a rack:

1. Determine the preferred placement of the 8620 chassis in the rack. Then,
mark the appropriate locations for the mounting screws in the rack. Use the
other set of brackets supplied with the chassis as a template.

2. For racks without threaded screwholes, slip a self-retaining nut onto each rail
hole selected and align the hole of the self-retaining nut with the hole in the
rail. For racks with threaded screwholes, skip to Step 3.

3. Line up the chassis mounting bracket with the selected holes in the rack and
install th e scr ews i nto th e chas sis m ountin g br acket (and t he se lf-ret aini ng nut ,
if used). Tighten all four screws until the chassis and is securely mounted in
the rack.

The following example shows front-mounting the chassis in a rack without
threaded screwholes.

wire) must be stripped of insulation to about 1/2 inch (12.7 mm) in length
before inserting the wires into the appropriate terminal on the –48V input
terminal block.

To supply two DC power sources to the 8620 chassis for power redundancy:

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

2. Clearly label these four power source wires as –48V A, RTN A, –48V B, and
RTN B respectively.

2-12 July 2003 8620-A2-GN20-40

Using AC Power with DC Power Backup

Procedure

✔ Make sure that the DC power source wires are not powered (i.e., the circuit

breakers are open).

✔ The ends of the DC power source wires (14–18 AWG solid or stranded wire)

must be stripped of insulation. If they are not stripped of insulation, strip the tip
of each wire (about 1/2 inch or 12.7 mm in length) before plugging the wire
into the appropriate connector on the –48V input terminal block. Ensure that
each wire is fully inserted into the terminal (until it can go no further).

To supply both AC and DC power to the 8620 chassis for power redundancy:

1. Plug the AC power cord into the IEC 320 receptacle labeled AC INPUT ( ).

2. Insert the wires for the DC power source into Terminal B 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.

2. Installation

NOTE:

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

2. Installation

Installing the Cards

Use a small- to medium-size Phillips screwdriver to install the SCP, MCP, SCM,
and DSL cards. If used:

n An SCP card must be installed in Slot A. Do not attempt to insert an SCP

card into any slot other than Slot A.

n An SCM card must be installed in Slot A. Do not attempt to insert an SCM

card into any slot other than Slot A.

n An MCP card must be installed in Slot 1. Do not attempt to insert an MCP

card into any slot other than Slot 1. Only use the MCP card in an 8620
chassis. Do not try to use an MCC or MCC Plus card, as they are
designed for a different chassis.

A DSL port card or MCP card may be replaced without disruption to user data (that
is, you can remove and reinstall a card without powering down the 8620 chassis
and disrupting user data on the other cards). To remove the port card or the MCP
card from the chassis, unfasten the screws on both ends of the faceplate. Then,
simply push the ejector handles outward and slide the card out. To remove an
SCP or SCM card, unscrew both ends of the card’s faceplate, then pull the levers
inward and slide the card out.

Removing an SCP or SCM card disrupts data on the DSL port cards.
When swapping a new card for an old card, it is important to note that the Hotwire

8620 GranDSLAM 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. If you need to refer to the MAC address, it is printed on the
SIM card. You must remove the SCP or SCM card from the chassis to see the
MAC address printed on the SIM card.

NOTE:

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.

2-14 July 2003 8620-A2-GN20-40

2. Installation

Procedure

To install a circuit card in the Hotwire 8620 GranDSLAM 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.

5. Make sure the SYSTEM OK indicator (on DSL cards) or SYSTEM ACTIVE
indicator (on the SCP card) is cycling off and on. If not, refer to

Troubleshooting Table in Chapter 4, Troubleshooting.

6. Secure the card by fastening the screws on each end of the faceplate. This is
required to maintain proper gasket pressure on the faceplate as well as proper
air flow.

NOTE:

For detailed information about the configuration and operation of the circuit
card, see the appropriate card User’s Guide.

version and a DC-powered version .
The AC version can be connected to a DC source to provide power

redundancy. With the DC version, two separate DC sources may be
employed to provide power redundancy.

The AC version accepts AC power (100–240 V, nominal; 50–60 Hz) and
converts it to DC power. The maximum current draw is 4 amps, or
250 watts at 120 VAC.

The DC version operates from a DC 48 VDC power supply (48 V,
nominal). The maximum current draw is less than 5 amps at 42 VDC.

Both versions distribute 48 VDC power from the power source to
individual cards via the backplane.
