HotWire 8546 Digital Subscriber Line (DSL) Card  
Installation Instructions  
Document Number 8546-A2-GN10-20

What is a 8546 DSL Card?  
A Digital Subscriber Line (DSL) 8546 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 8546 DSL card is used in a HotWire 8600 or 8800  
DSL Access Multiplexer (DSLAM) chassis connected to a HotWire 5446 Remote  
Termination Unit (RTU), it provides high-speed Internet or Intranet access with  
dynamic IP addressing and enhanced security 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.

Cables You Need  
The following customer-provided cables are used with this product:  
H
Plug-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.  
H
One 8-pin modular UTP (Unsheilded Twisted Pair) CAT5 cable for each  
connection from a LAN/WAN port associated with a 8546 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 8546 DSL Cards  
Use a small- to medium-size flat-blade or Phillips screwdriver to install the  
8546 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 8546 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 8546 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 8546 DSL card:  
1. Remove the filler plate from the desired slot.  
2. Insert the 8546 DSL card into this slot:  
— For a HotWire 8600 DSLAM chassis – hold the 8546 DSL card  
horizontally with component side facing up and insert it into the left and  
right card guides.

3. Slide the 8546 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 8546 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 8546 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 8546 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 8546 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 8546 DSL card with a new 8546 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 8546 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 8546 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:

2. Replace the longer Telco cable captive screw with a shorter connector  
captive screw, which is provided with the HotWire DSLAM 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 8546 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 8546 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.  
Refer to Pin Assignments on page 9 for pin assignments.
