voltage points or other risks. Refer all servicing to qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be required by the regulatory
inspection authority for the installation site, are the responsibility of the customer. To reduce the risk of fire, use a
UL Listed or CSA Certified, minimum No. 26 AWG telecommunication cable.
7. When installed in the final configuration, the product must comply with the applicable Safety Standards and
regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If products
installed in separate buildings are interconnected, the voltage potential may cause a hazardous condition.
Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if necessary,
implement corrective action prior to interconnecting the products.
9. Input power to the DC configuration of this product must be obtained from a SELV (Safety Extra Low Voltage)
source (less than 60 VDC, and double insulate from hazardous voltages).
10. If it becomes necessary to replace either of the accessible A or B fuses (located on the front panel): For continued
protection against fire and/or shock, replace the fuse with the same rating, manufacturer, and manufacturer’s part
number as originally installed in the unit. These fuses are readily available through your local Paradyne distributor,
or you may order replacement fuses by contacting Paradyne directly.
11. When powered by –48 VDC, this product may only be used in a Restricted Access Location in accordance with
articles 110-16, 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70. A Restricted Access
Location is a secure area (dedicated equipment rooms, equipment closets, or the like) for equipment where access
can only be gained by service personnel or by users who have been instructed about the reasons for the
restrictions applied to the location and about any precautions that must be taken. In addition, access into this
designated secured area is possible only through the use of a tool or lock and key, or other means of security, and

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.

Hotwire 8620 GranDSLAM Features
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.

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.
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.

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.

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

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.

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.
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
n
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.
An SCM card must be installed in Slot A. Do not attempt to insert an SCM
card into any slot other than Slot A.
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. 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.

3. Carefully slide the card into the slot until the card meets the connectors on the
backplane. Then press in on the insertion/ejection levers until the card is fully
seated.
4. For desktop installations, press on the card’s front panel with one hand and on
the back of the 8620 chassis with the other until the card’s connector seats in
its mating connector.
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
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.

Power
The Hotwire 8620 GranDSLAM chassis is available in an AC-powered
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.
