HotWire 8546 Digital Subscriber Line (DSL) Card
Installation Instructions
Document Number 8546-A2-GN10-20
October 1997
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.

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.

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.
