Many products have large, easy-to-read legends to
allow for the easy configuring of the product. This
installation manual contains detailed instructions.
Most included software has automatic installation
programs to place the software correctly onto your
computer. However, as all computers are configured
differently, you may be required to perform some basic DOS or Windows
tasks. If you are not familiar with basic DOS commands such as DIR,
CD, or EDIT, you should check your DOS manual, or seek assistance
from you local computer dealer to install the product.

We use many world-class quality assurance programs to ensure the
product you purchased is of the highest caliber. Sometimes, however, a
component may be missing from the box, or is damaged or corrupt in
some way. If this happens, immediately return the entire package to your
place of purchase so you may exchange it for a new one. Your dealer
should be able to provide you with an exchange far more quickly than by
contacting us directly. If for some reason you are unable to return the
product directly to its place of purchase, refer to the “Servicing Your

Functional DescriptionFunctional Description
The BocaNET-24 is an implementation of an IEEE 802.3/
Ethernet repeater or hub. It provides 24 10BASE-T ports, one
10BASE2 port, one AUI port, and one expansion port in a
single hub. The BocaNET-24 complies with the full set of
repeater basic functions as defined in section 9 of ISO 8802.3
(ANSI/IEEE 802.3). These functions are defined below:
Repeater FunctionRepeater Function

If any single network port senses the start of a valid packet
on its receive lines, then the BocaNET-24 will re-transmit the
received data to all other enabled network ports.

When re-transmitting a packet, the BocaNET-24 ensures that
the outgoing packet complies with the 802.3 specification in
terms of preamble structure, voltage amplitude, and timing
characteristics.

The BocaNET-24 implements a built-in jabber protection
scheme to ensure that the network is not disabled due to the
transmission of excessively long data packets.
Collision HandlingCollision Handling
Collision Handling
Collision HandlingCollision Handling
The BocaNET-24 will detect and r espond to collision
conditions as specified in 802.3. It will also protect the
network from excessive collisions by “partitioning” the
offending port from the rest of the network. Once a port is
partitioned, the data received from that port will not be
repeated. However, any other data on the network will be retransmitted on that port. If the collisions that cause the
partitioning cease, the port will be re-connected to the rest of
the network.
The status of the partitioning scheme can be checked at any
time by observing the bi-color LINK/PRT LED on the front
of the BocaNET-24. If any ports are currently partitioned, the
corresponding LED will be

The BocaNET-24 implements the Link test function as
specified in the 802.3 10BASE-T standard. It transmits Link
test pulses to any port after that port’s transmitter has been
inactive for a short period of time. The device connected to
the port will respond in the same manner. The Link Status of
ports 1-24 can be viewed on the bi-color LINK/PRT LEDs of

You will need one pair of
rack-mounting angles for
every BocaNET-24 case you
mount to the wall. Attach
the 1 1/2" angle portion (4
holes) to two sides of the
case using the 4-40 1/4"
screws (included). Attach
the 7/8" angle portion (2
holes) to the wall. This will
require 4 additional screws.

The BocaNET-24 has 24 10BASE-T UTP (unshielded twisted
pair) ports to connect to other hubs or workstations. This
connection uses an RJ-45 8-pin connector. When connecting
to workstations, a straight-through connector is used. When
connecting to other hubs, a “crossed” cable is used.

The BocaNET-24 has one 10BASE2 (BNC) connector which
interfaces directly to a 10BASE2 (“thin” Ethernet) network.
The 10BASE2 connection must be to RG58 A/U or C/U 50ohm coaxial cable. The ends of the cable segment must have
50-ohm terminators installed. Up to 30 connections (taps)
can be made to a 10BASE2 segment. The BocaNET-24 is
connected to a 10BASE2 segment with a BNC T-connector,
which is illustrated on the next page.

The BocaNET-24 has one AUI connector which interfaces
with a 10BASE5 (“thick” Ethernet) network. The AUI port is
normally used to connect to 10BASE5, but can also be used
to interface with other types of networks such as 10BASE2,
10BASE-T, or 10BASE-FL. A sample connection is shown

wires, with each pair dif ferentiated by color. Each twisted
pair link segment must have an RJ-45 male connector
attached to both ends. Pins 1 and 2 on the RJ-45 connector
are for transmitting data while pins 3 and 6 ar e for receiving
data. See chart below:

Two Ethernet 10BASE-T devices can communicate only if the
transmitter on one device is connected to the receiver of the
other device. The 10BASE-T specification suggests that the
crossover function be implemented in the concentrator itself.
On the BocaNET-24, this crossover function is implemented
in all ports. The switch for Port 24 allows a straight-through
connection for cascading hubs.
When a twisted-pair port labelled with an “X” is connected
to a device which does not support the crossover function,
“straight-through” wiring can be used (see 4.4).
When connecting two identical twisted-pair ports (that is,

because of excessive collisions (concentrator receiving data
from two or more devices at the same time), or jabbering.
Each BocaNET-24 concentrator also has:
• A GREEN power LED to indicate that the BocaNET-24 has
power.
• One YELLOW collision LED to signal a network collision.
If this light stays ON, observe the bi-color link/partition
LEDs to isolate which device is causing the collision.
• One GREEN activity LED to indicate network activity.
