Product Description
Workgroup Repeater expand a network by extending individual Ethernet
segments. Where standard distance limits are not sufficient, and where different media types
need to come together in one Ethernet link, Black Box Workgroup Repeater Repeaters are
ideal. They support connections to all standard Ethernet media types.
Each Workgroup Repeater unit is a complete operational unit with internal power
supply, all enclosed in a compact, rugged metal enclosure. The media connectors and the
chassis status LEDs are all conveniently accessed from the front. The unit is easily installed
and is suitable for wiring closet shelf, vertical wall, or desktop mounting.
Workgroup Repeaters provide full repeater functionality per IEEE 802.3
specifications and in compliance with Ethernet V1.0/2.0 standards. Workgroup Repeaters
operate as homogeneous-media repeaters (two segments of the same media type connected)
4
BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
or as mixed-media repeaters (two segments of different media type connected). Using two
RPMs, two full-length segments of all media types are supported by each WorkGroup
Repeater model and configuration. The family of Workgroup Repeater models supports all
combinations of standard Ethernet media.
2.2.1
Workgroup Repeater Chassis
The Workgroup Repeater functions as an in-line repeater. The Workgroup
Repeater chassis houses the main repeater circuit board, and two Repeater Port Modules.
The main repeater board is used to power the two RPM cards and as a connection plane
between the cards. The chassis has two connector slots, each of which supports one
Repeater Port Module (RPM) to provide either 10BASE2, 10BASE5, 10BASE-FL, FOIRL,
or 10BASE-T connectivity. The individual RPMs are used for one Ethernet segment each,
and provide full IEEE 802.3 repeater
functionality supporting a full length

segment. Individual RPMs are equipped
with a single media interface connector. Any RPM can be installed in either slot of the
Black Box Workgroup Repeater chassis.
All LEDs common to the WorkGroup Repeater unit are front-mounted for easy
visual monitoring of status during operation. To simplify media connections, each media
interface port and the port-specific LED’s are accessible from the rear of the unit, along
with the AC power cord port.
The internal power supply is auto-ranging to handle any AC power type
worldwide. Power input may range from 90 to 260 vac, with a frequency rating of 47 to 63
Hz. The unit is equipped with a rear mounted IEC-type recessed male AC power
connector. (When shipped for use in areas other than 115 vac, a power cord will not be
included). The 200X unit is convection-cooled for silent operation.
The Workgroup Repeater base unit features Power (PWR), Receive (RX),
Collision (COL), and Jabber (JAB) LED status indicators located in the front of the unit.

BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
These LEDs provide a visual assessment of the operational condition and aggregate
network activity at the unit, and are in addition to the LEDs on each individual RPM.
2.3
Workgroup Repeater - Repeater Port Modules (RPMs)
For standard WorkGroup Repeater models, there is an option of five different
Repeater Port Modules (RPMs) each equipped with its own unique connector type. The
assortment of standard network connector types for these RPM includes BNC (ThinNet),
AUI (ThickNet), RJ-45 (UTP and STP), Fiber-ST (Fiber, "Twist-lock" type) and Fiber-SC
(Fiber, “Snap-in” type) are available.

The RPM-BNC repeater module is
equipped with a standard
RPM-BNC
10BASE2 coax connector. This RPM performs full IEEE 802.3 repeater functionality and
is used for 10BASE2 ThinNet (commonly referred to as BNC) connections.
The RPM-BNC module is designed with a special switch -selectable internal
termination function that eliminates the need for a "tee" connector and a 50 ohm
terminator. To take advantage of internal termination, the slide switch should be in the
"DOWN" (or right-side) position. In this configuration, the 10BASE2 segment is directly
attached to the BNC port where it is internally terminated. When the switch is in the "UP"
(or left-side) position, the BNC port requires a "tee" connector (not supplied) and a 50 ohm
6
BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
terminator for proper termination. Certain applications may require a "tee" connector, used
as a tap, to allow the 10BASE2 coax segment to continue on past the RPM-BNC
connection.
The RPM-BNC module includes one partition (PART) and one receive (RX)
LED, which are visible from the rear. The PART LED flashes AMBER to indicate that the
segment has been automatically partitioned. As soon as normal transmission resumes, the
segment will be automatically re-established. The RX LED illuminates GREEN
intermittently to indicate data is being received.
Important Note:

RPM-TP
For the RPM-BNC Termination Switch DOWN (or right): Internally Terminated

(Twisted Pair)
The RPM-TP card supports Ethernet twisted pair segments of any standard
length. It is equipped with a single RJ-45 connector. The RJ-45 connector is shielded to
minimize emissions and will allow both unshielded twisted pair (UTP) and shielded twisted
pair (STP) segment connections.
The RPM-TP module is also
equipped with a slide switch to allow
for cascaded or up-link connections.

When used for segments going to workstations and other user device connections, the
switch should be in the DOWN (or RIGHT) position. The LINK LED is particularly useful
in choosing the proper position for the up-link switch. If the LINK LED is illuminated, the
switch is set properly! If not, change the switch setting.
The RPM-TP will support 10BASE-T unshielded twisted pair wiring (UTP)
environments with maximum segment distances up to 100m (325 ft.), or shielded twisted
pair wiring (STP) of 150m (500 ft.). This module is designed with internal transceiver
7
BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
functionality. In addition to PART and RX (same as RPM-BNC, Section 2.3.1), the RPMTP has a LINK LED to indicate proper connectivity with the remote device.
Important Note: For the RPM-TP MDI-X Crossover Switch DOWN(or Right) for workstations and user connections.
UP (or Left) for Up-Link connections to other hubs, etc.
The RJ-45 pins normally (TP crossover switch DOWN or RIGHT) are per the standard for
hub-to-user twisted pair wiring: 1 = receive+, 2 = receive-, 3 = transmit+, 6 = transmit-,
other pins not used. When the TP crossover switch is UP or LEFT, the pins of the RJ-45
port are per the standard for up-links using twisted pair wiring, i.e., the transmit and the
receive pairs are exchanged: 1 = transmit+, 2 = transmit-, 3 = receive+, 6 = receive-, other
pins not used.
2.3.3

slide-lock, and performs full IEEE
802.3 repeater functionality. It is used
to provide connectivity with a
2
1
10BASE5 (ThickNet) backbone or to
any AUI segments. A transceiver is
required when connecting to a
RPM-AUI
ThickNet segment and the RPM-AUI
supports this convention. The RPM-AUI is also a "universal" Ethernet media interface as it
may be used with a variety of different mini-transceivers to provide connectivity to any
media type.
The RPM-AUI card is equipped with Partition (PART) and Receive (RX) LEDs
which function the same as the identical LEDs on the RPM-BNC (Section 2.3.1 above).
The RPM-AUI card is also used for connecting Ethernet devices using standard
AUI cabling. In this situation, it is important to consider the AUI segment length or
distance to the attached device.
The maximum transmission distance between a backbone transceiver equipped
with an AUI connector and the RPM-AUI card will vary. When an AUI cable is used to
connect the RPM-AUI directly to a backbone transceiver, the maximum AUI segment
length is allowed. If the RPM-AUI is connected to a transceiver that has been cascaded
from another transceiver, the maximum AUI segment length is reduced.
8
BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
According to Ethernet standards, the maximum distance from the transceiver AUI
connector and the attached device ( RPM-AUI) is 50m (165 ft.). The AUI segment
maximum length is reduced in cascaded configurations. See the following note.
Important Note: The maximum transmission distance is decreased by 6m (20
ft.) for every additional level of network transceiver device "dropped" or "cascaded" from
the original backbone transceiver tap.
The RPM-AUI connector supports standard IEEE signals, summarized in Table 2.3.3.

Features and Benefits
Models for Homogeneous Media
Workgroup Repeater models support extensions of all standard Ethernet
media types, including BNC-BNC, AUI-AUI, TP-TP, and Fiber-Fiber. Users
may expand network distances while retaining the media of choice with
these models.
Models for Mixed Media
Since the Workgroup Repeater port connectors are modules, the units are
ideal when different media types need to be brought together at a repeater
unit. Two-Port models are available with all combinations of BNC, AUI, TP,
and Fiber. These mixed-media models ensure standard signals and up-tofull-length distance on each network segment, accommodating changes in
media preferences as networks change over time.
RPMs (Repeater Port Modules) for All Standard Ethernet Media
The RPMs support all of the various IEEE 802.3 standards including,
10BASE-FL, FOIRL, 10BASE2, 10BASE5 and 10BASE-T.
Fiber Ports Meet 10BASE-FL Specification, 2000 meters distance
The WorkGroup Repeaters fiber RPMs meet the "FL" specification for 2 Km
distance. They also support the older FOIRL specification rated at 1 Km.
Front-Mounted LEDs
Status LEDs are all readily visible from the front for ease of monitoring
operational status over time. (Port-specific LED’s used for checking out the
connections during set-up) are in the rear along with the media ports.
Optional wall-mounting convenience
The compact Workgroup Repeaters are supplied with mounting clips and
screws to accommodate installation at any location, wall or shelf, within
reach of an AC power outlet. When networks are expanded and segments
need to be extended or changed at out-of-the-way locations, the WorkGroup
Repeater package is ideal.
World-wide applications
An internal universal power supply allows the WorkGroup Repeater to be
used throughout the world.

Applications
Workgroup Repeater are generally used to extend Ethernet segments of the same
media type. Several models are available for this task, including BNC to BNC, AUI to
AUI, Twisted Pair to Twisted Pair, and Fiber to Fiber. This family of homogeneous-media
repeater models support each standard Ethernet media type, and allow users to expand
network distances while retaining the wiring media of choice. As many as four repeaters
may be connected in series to connect users at the extremities of 5X the standard segment
distance while still adhering to the Ethernet "four repeater" rule.
The Workgroup Repeater units are ideal when different media types need to be
brought together at a repeater unit. As media type preferences change over time and as
networks expand to new distances with system growth, the requirement to convert media
types while ensuring standard signals on both network segments is increasingly common.
The Workgroup Repeater meet this requirement with all media-combination types available.

The internal auto-ranging power supply of the Black Box Workgroup Repeater
permits it to be installed anywhere in the world. In the workplace or in a wiring closet,
WorkGroup Repeater unit may be conveniently shelf or table-top mounted and plugged into
a standard AC power convenience outlet for a simple installation. For rack-mounting, two
WorkGroup Repeater units fit side-by-side in a standard rack-width space.
The compact, lightweight design and the mounting brackets and velcro strip
included with the WorkGroup Repeater units make them ideal for mounting anywhere a
segment length extension of any media type is needed. These units are suitable when
network segment extensions are needed in offices, labs, hallways and storage areas.

INSTALLATION
This Section discusses location and installation options for the Workgroup
Repeater.
3.1
Locating the Workgroup Repeater
The location of the Workgroup Repeater is dependent on the physical layout of
the network and the area to be served. The unit should be set-up in a location that will
accommodate easy and equal access to planned network devices and/or segment
connections.
Locate an AC receptacle that is within six feet (2 meters) of the Workgroup
Repeater site. The rugged steel case of the Workgroup Repeater will protect it from
accidental damage in a wiring closet or in a workplace setting. Keep an open area around
the unit so that convection cooling can occur while the unit is in operation.
3.1.1
Black Box Workgroup Repeater Table-Top / Shelf Mounting
The Workgroup Repeater unit has four rubber feet to provide stability while not
scratching finished surfaces. It is typically shelf-mounted either in a wiring closet or in an
open area. To conserve shelf space, it may be desirable to mount several units on top of
each other. If so, this may be readily done as the Black Box Workgroup Repeater's steel
case is strong.
Should vertical mounting of the unit (such as on a wall surface) be desired,
operation and cooling are not impaired. Mounting clips for vertical mounting are available.
3.2
Connecting Ethernet Media
The Workgroup Repeater is specifically designed to support connections for any
two Ethernet segment media types within a single unit. This is accomplished by using a
family of Repeater Port Modules (RPMs). The various media types supported along with
the corresponding IEEE 802.3 standards and connector types are as follows:

3.2.1
Connecting Twisted Pair (RJ-45, Unshielded or Shielded)
The following procedure describes how to connect a 10BASE-T twisted pair
segment to the RJ-45 port on the RPM-TP. The procedure is the same for both unshielded
and shielded twisted pair segments.
1. Using standard 10BASE-T media, insert either end of the cable with an RJ-45 plug
into the RJ-45 connector of the RPM-TP. Note that, even though the RPM-TP connector
is shielded, either unshielded or shielded 10BASE-T cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If the LINK
LED is not illuminated, change the setting of the up-link switch. If this does not help,
ensure that the cable is connected properly and is not defective.
The RPM-TP is equipped with a up-link slide switch to accommodate repeater-torepeater connections without special cross-over connectors.
3.2.2
Connecting ThinNet 10BASE2 (BNC)
Connect the ThinNet coax cable to the BNC connector on the RPM-BNC card in
the same manner as is done for any standard BNC connection. The RPM-BNC port is
specially equipped with an internal termination switch on the front of the card (see Section
4.1 for a description of this switch). This eliminates the need to use a "tee" connector when
the BNC cable is ending at the connection to this RPM. Some applications may require a
"tee" connector, used as a tap, to allow the 10BASE2 coax segment to continue on past the
RPM-BNC connection.
3.2.3 Connecting ThickNet 10BASE5 (AUI)
Using the steps below as a guide, attach a new or existing 10BASE5 ThickNet dropcable directly to the AUI connector on the RPM-AUI port.
1. Plug the male end of the cable into the female AUI connector on the RPMAUI card.
2. Engage the AUI connector slide lock to insure maximum connectivity.
3. Connect the opposite end of the cable into a network AUI port. (This
could be a network backbone transceiver, a hub or fan-out with an AUI
backbone port, or an AUI module in a concentrator.)
The RPM-AUI card may also used for connecting to other Ethernet devices using
standard AUI cabling. In this type of situation, it is important to consider the AUI segment
length to the attached device, including any cascading. (See Section 2.2.3 for detailed
information on the RPM-AUI card, connector pins, and cable lengths.)

3.2.4 Connecting Fiber Optic 10BASE-FL and FOIRL (ST-type, “Twist-Lock")
The following procedure applies to FOIRL and 10BASE-FL applications using an
RPM-ST card with ST-type fiber connectors. (The primary difference between FOIRL and
10BASE-FL for users is the maximum distance allowed. 10BASE-FL is used for a fiber
segment length of up to 2000m, while FOIRL is used for fiber segments of up to 1000m in
length.)
1. Before connecting the fiber optic cable, remove the protective dust caps from the
tips of the connectors on the RPM-ST. Save these dust caps for future use.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting.
Note:
3.
4.
5.
3.2.5
One strand of the duplex fiber optic cable is coded using color bands
at regular intervals; you must use the color-coded strand on the
associated ports at each end of the fiber optic segment.
Connect the Transmit (TX) port (light colored post) on the RPM-FST to
the Receive (RX) port of the remote device. Begin with the color-coded strand of
the cable for this first TX-to-RX connection.
Connect the Receive (RX) port (dark colored post) on the RPM-FST to the
Transmit (TX) port of the remote device. Use the non-color coded fiber strand for
this.
The LINK LED on the front of the RPM-FST will illuminate when a proper
connection has been established at both ends (and when power is ON in the unit).
If LINK is not lit after cable connection, the normal cause is improper cable
polarity. Swap the fiber cables at the Port Module connector to remedy this
situation.
Connecting Fiber Optic (SC-type, "Snap-on")
The same five-step procedure as for fiber ST-type applies to FOIRL and
10BASE-FL applications using an RPM-FSC card used with SC-type fiber connectors.
Follow the five steps as described in the paragraph above.
When connecting fiber media to SC connectors, simply snap on the square male
connector into the female SC jack of the device until it clicks and secures.

OPERATION
This section describes the functionality and operation of the Workgroup Repeater.
4.1
Repeater Functionality
Workgroup Repeaters operate as mixed-media or homogeneous Ethernet
repeaters. Both types are compliant with IEEE 802.3 specifications and supports all IEEE
defined media, including 10BASE-T, 10BASE-FL, FOIRL, 10BASE2, and 10BASE5. The
following describes the basic functionality of the Workgroup Repeaters.
1. Repeater Functions: Each RPM port operates in conjunction with the
controller functions of the WorkGroup Repeater base unit, functioning together as
a fully compliant Ethernet repeater. Each WorkGroup Repeater unit counts as a
single repeater.
2. Collisions: When a collision is detected at a port other than the original
receiving port, it generates a jam pattern to the other ports. When a collision
signal is detected at a receiving port, it generates a jam pattern to the other port.
The sequence of jam signals depends on the sequence and location of collisions.
3. Partitioning and Re-connection: A Workgroup Repeater will automatically
disconnect (partition) any segment (port) when 64 consecutive collisions occur or
after 6.5 ms of continuous transmissions. Network integrity is checked every 800
ms and segment (port) reconnection occurs after a 512-bit packet is transmitted
without error.
4. Link Status: The WorkGroup Repeater RPMs indicate link integrity for fiber
optic and twisted pair segments. Broken cables or a loss of power at any point in
twisted pair and fiber segments will turn off the LINK LED indicator on the
associated RPM.
4.2
Powering the WorkGroup Repeater
The WorkGroup Repeater incorporates an internal universal power supply, and
has a recessed male IEC connector for the AC power cord at the right-rear. A six foot
power cord is supplied with each unit. (Except units being shipped from the U.S. factory to
outside the United States and Canada will not include a power cord.)
The WorkGroup Repeater auto-ranging power supply supports installation
environments where the AC voltage is from 90 to 260 volts with a power input frequency
16
BLACK BOX WorkGroup Repeater Installation and User Guide (02/02)
between 47 and 63 Hz, and will consume no more than a maximum of 15 watts. The power
connector is located on the back of the unit. In order to power down the unit, simply
unplug the power cable from either the wall socket, power strip or the power connector on
the back of the unit.
When connecting various Ethernet media, there is no need to power down the
unit. Individual segments of any media type can be connected or disconnected from RPMs
without concern for AC power-related problems or damage to the unit.
4.3
Chassis LEDs
The WorkGroup Repeaters are equipped with four LEDs located on the front of
the chassis unit. These LEDs include Power (PWR), Receive (RX), Collision (COL) and
Jabber (JAB). They are used to provide visual indication about the operational condition
and traffic activity of the unit and its associated RPM ports.
