RADIO FREQUENCY INTERFERENCE STATEMENTS

This equipment generates, uses, and can radiate radio frequency energy and if not
installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.

Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of Industry Canada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par Industrie Canada.

1. Introduction

These instructions provide basic installation procedures for the SDSL Network
Extender Subscriber (LRA1200A-S).

CAUTION

We strongly recommend that you use proper static-protection
techniques when installing and handling this equipment.

NOTE

An SDSL Network Extender Subscriber must be connected (via the DSL
line) to an IP DSLAM Access Mux Module, such as the SDSL 12-Port
Access Mux 2000 Module (LRA1207C). Two subscriber units may not be
connected back-to-back.

2. Installation

Step #1: Unpacking the Unit

Unpack the Network Extender and power supply. If anything appears to be broken
or missing, contact Black Box immediately at 724-746-5500.

Step #2: Plug in the Power Supply

Plug the power supply into both the power source and the back of the unit. It does
not matter which order. Verify that the Power LED is lit.

Step #3: Plug in the DSL Connection

Plug in the DSL connection (see the bottom label for SDSL connection pinout
information).

NOTE

The length of the copper cable used between the local Network Extender
and the remote Network Extender will affect the linking of the DSL
connection. If the distance is greater than a particular speed will
support, the units will not link up. Also, it may take anywhere from one
to five minutes for the DSL connection to link up, depending on cable
quality and distance.

Step #4: Verify the DSL Connection

Verify the DSL connection via the “Available SDSL Connection” LED on the front
of the Extender. A steadily pulsing LED (once per second) indicates that the DSL
connection is established and operational.

NOTES

For an overview of the unit’s LEDs and their functions, refer to LED
Indicators on the next page.

When the DSL connection is not present, the LNK, TX, and RX LEDs on
the provider unit will each glow steadily. Even though the Ethernet LNK
LED is on, link is not presented to the upstream Ethernet device. When
the DSL link comes up, LEDs will function as normal. The Ethernet
device that is connected to the provider unit can be notiied of an alarm
on the DSL link. For example, if the Ethernet device (switch or router)
loses Ethernet link on the port to which the provider unit is attached, a
trap can be sent to the network management station that an event has
occurred either on the corresponding DSL link, or the Ethernet link
itself.

Step #5: Verify the Physical Link

Plug in the local Ethernet connection and verify the physical link(the LNK LED on
the front of the unit will come ON steadily). See the bottom label for Ethernet
connection pinout information.

NOTE

For most applications, a straight-through Ethernet cable is used when
plugging the Network Extenders into a PC. Use a crossover cable when
plugging into a hub or switch. Verify the pinout of the Ethernet device
into which you are connecting the Network Extender to determine which
type of cable is required.

Once the units have established both DSL and Ethernet links on both sides of the
connection, normal data communication will flow through the units. This will
provide a very long Ethernet connection at DSL speeds.

LED Indicators

The DSL/Ethernet ports feature the following status LEDs for at-a-glance
monitoring.

• Available SDSL Connection LED: Pulsing green (once per second) indicates
that the DSL connection is operational and that the Network Extender is
receiving either valid data packets or status packets from the remote unit on
the other side of the DSL connection.

• Power: Steady green indicates normal operation.

• Collision: Flashing red indicates collision on the Ethernet segment.

• Rx: Flashing amber indicates data receive from the Ethernet segment. Steady
amber indicates that the DSL connection is not present.

• Tx: Flashing amber indicates data transmit to the Ethernet segment. Steady
amber indicates that the DSL connection is not present.

• Lnk: Steady green indicates that the Ethernet link has been established. Steady
green (if accompanied by corresponding steady amber TX and RX LEDs)
indicates that the DSL connection is not present.
