About This Document  
This guide is written for administrators and technicians who install devices at the  
central office (CO) or at a Network Service Provider (NSP) location adjacent to the CO.  
It should be used in conjunction with the appropriate Hotwire DSL card User’s Guide or  
Network Configuration Guide, which describes how to plan the data networks  
surrounding the DSLAM and specific DSL cards.  
To install the customer premises (CP) portion of the Hotwire 8610 DSLAM, refer to the  
appropriate Hotwire Remote Termination Unit (RTU) Customer Premises Installation  
Instructions and Hotwire POTS Splitter Customer Premises Installation Instructions.  
What is the Hotwire 8610 DSLAM?  
The Hotwire 8610 Digital Subscriber Line Access Multiplexer (DSLAM), which can be  
installed in the CO or at a customer location adjacent to the CO, is a low-startup-cost  
alternative to the Hotwire 8810 DSLAM chassis. It provides high-speed Internet or  
intranet access.  
The following illustration shows a high-level view of an example Hotwire configuration.

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

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
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.  
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.

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.  
NOTE:  
You must order the MCP and DSL cards separately. They are not provided with the  
chassis.  
5
 
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 @ 110 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 AWG, 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
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.  
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 CAT5 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.  
6
 
— 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.

Hotwire 8610 DSLAM Chassis Installation  
The Hotwire 8610 DSLAM chassis is designed to be stacked one on top of the other on  
a desktop or table, or mounted in a 19-or 23-inch rack (front or center mount). Up to  
three 8610 chassis can be stacked on a table or desktop. Mounting brackets are  
provided for mounting in 19- or 23-inch racks.  
You will need a large, flat-blade screwdriver and a Phillips screwdriver to install the  
8610 chassis in a commercial EIA-standard 19- or 23-inch rack. You will need a small  
phillips screwdriver to change the STACK POSITION switch.  
Stacking the 8610 Chassis  
" Procedure  
To stack the 8610 chassis on a desktop or table, select the stack position, and  
interconnect the stack:  
1. Place the first Hotwire 8610 DSLAM chassis on a desktop or table.  
2. Place the second Hotwire 8610 DSLAM chassis directly on top of the first chassis.  
3. Place the third Hotwire 8610 DSLAM chassis directly on top of the second chassis.  
4. Change the setting of the rotary STACK POSITION switch to the appropriate  
position of the chassis using a small Phillips screwdriver. Examine the switch  
closely to be sure the switch is set so that the notch points to the position number.

Interconnecting 8610 Systems  
" Procedure  
To interconnect multiple 8610 systems:  
1. Connect the end of an 8-pin modular cable into the Management OUT port of the  
base chassis.  
2. Dress the 8-pin modular cable to the left and under the chassis, behind the foot,  
and up the side of the unit.  
3. Plug the other end of the 8-pin modular cable into the Management IN port of the  
8610 chassis above, dressing the cable as in the previous step.  
4. Repeat for the next 8610 chassis, connecting the Management OUT port of  
Chassis 2 to the Management IN port of Chassis 3.  
NOTE:  
Bus cables must use Unshielded Twisted Pair (UTP) CAT5 cable. The total bus  
cabling should not exceed 25 feet.  
10  
 
The following illustration shows the designated number for each DSL card slot in a  
stack.  
NOTE:  
This illustration shows a stack of six Hotwire 8610 systems, which is valid for rack  
mounting. However, the same relationship of software-assigned slot numbers  
applies to two stacks of three each, mounted on a desk or tabletop and connected  
by a bus cable. The base chassis must still have the MCP card in physical Slot 1  
with the base chassis Stack Position switch set to 1. The software does not assign  
a slot number to the MCP card.

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.

Installing the Cards  
Use a small- to medium-size flat-blade screwdriver to install the MCP and DSL cards.  
The MCP card must be installed in Slot 1 of the base chassis.  
CAUTION:  
Do not insert the MCP card into Slots 2 or 3 as this will damage the DSLAM  
chassis. The MCP card must be used in Slot 1 of the base 8610 chassis for  
proper functionality. Only use the MCP card in an 8610 chassis. Do not try to  
use an MCC or MCC Plus card.  
A circuit card may be replaced without disruption to user data (i.e., you can remove and  
reinstall a card without powering down the 8610 chassis and disrupting user data on  
the other cards). To remove the 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.  
18  
 
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.

engages its mating connectors on the backplane.  
4. Press on the card’s front panel with one hand and on the back of the 8610 chassis  
with the other until the card’s connector seats in its mating connector.  
5. Make sure the OK SYSTEM indicator on the card’s faceplate is ON (green). If not,  
refer to Troubleshooting on page 25.  
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.  
19  
 
NOTE:  
For detailed information about the configuration and operation of the circuit card,  
see the appropriate card User’s Guide.  
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
H
The yellow FAN ALM LED on the front panel must be OFF.  
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).

Power  
Two versions of the Hotwire 8610 DSLAM chassis are available: an  
ac power version and a dc power 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 (100–250V, 50–60 Hz) and  
converts it to dc power. The maximum current draw is less than  
1.75 amps, or 75 watts @ 110 Vac. At maximum configuration with  
3 DSL cards, the system will not exceed 85 watts of power  
dissipation.  
The Hotwire 8610 DSLAM chassis dc version operates from a  
standard 48 Vdc power supply (40.0 to – 60.0 Vdc). The  
maximum current draw is 2 amps. At maximum configuration with 3  
DSL cards, the system will not exceed 75 watts of power  
dissipation.  
Each power version distributes 48 Vdc power from the power  
source to individual cards via the backplane.
