Product Description
Overview
The AT-MR840TF is a 10Base-T /10Base-FL standalone, unmanaged hub that
has eight UTP (RJ45) ports and one fiber optics port. There are two types of
fiber optic ports that accommodate an uplink connection to the backbone. The
ST version accommodates a fiber ST cable whereas the SC version
accommodates an SC cable. The SC/ST uplink port provides a means for media
conversion and increased distance.
In addition to uplink capabilities, the hubs can be cascaded using one of the
eight RJ45 ports or the fiber ST/SC port to connect to other hubs to increase the
segment size. Up to four hubs can be interconnected per IEEE 802.3 standards.
The AT-MR840TF hubs support full-length cable segments with the maximum
number of supported devices allowed within IEEE 802.3 standards. The hub is
equipped with an internal universal AC power supply and can be desk or wallmounted. For wall-mounting instructions and materials, refer to AT-BRKT17.

AT-MR820TR Hub Installation Guide
Functional Description
The AT-MR840TF hub incorporates the latest technologies, including a custom
Application Specific Integrated Circuit (ASIC) and Surface Mount Technology
(SMT). Employing state-of-the-art technologies results in enhanced
functionality, increased reliability, and improved performance and as detailed
in the following list of features:
Packet Regeneration
Packet regeneration is a high-performance network feature that includes the
regenerating of the packet preamble, retiming of data packets, and the
extension of collision fragments. When transmitting a packet, the hub ensures
that the outgoing packet complies with IEE 802.3 specification in terms of
preamble structure, signal amplitude, and timing characteristics. Data packets
repeated will contain a minimum of 56 preamble bits before start-of-frame
delimiter. In addition, the hub restores signal symmetry to the repeated data
packets, removing jitter and distortion caused by the network cabling.
Link Integrity
The IEEE 802.3 defined link integrity test function continually monitors the
twisted pair cable to ensure link continuity of the receive pair between the user
node and the hub.
Autopartitioning
Also known as segmentation, each segment will be automatically partitioned
whenever 32 consecutive collisions occur on the segment. One valid packet will
reset the segment and return it to the auto reconnecting segment. Any of the
twisted pair ports can be partitioned if the frequency of collisions becomes
excessive. The enabled network port is partitioned if one of the following
conditions occurs on that port:
❑ A collision condition exists continuously for more than 2048 bit times
❑ A collision condition occurs during each of the 32 consecutive attempts
to transmit to that port.
When there is no more collisions in the partitioned port and activity of 512 bit
times or more is detected, the partition is released and the port is reconnected.
3
Page 24
Product Description
Jabber Lock-up Protection
Jabber lock-up protects the hub from being overrun with excessively long data
packets by isolating segments that contain these oversized packets (exceed
maximum packet length). Therefore, jabber lock-up automatically prevents
data which exceeds the allowed duration (usually 5 ms) from reaching the hub,
or if the hub has been continuously transmitting for more than 65,536 bit times.
This protection scheme automatically interrupts transmission for 96 bit times.
Fragment Extension
If the total packet length received is less than 96 bits, including preamble, the
packet length is expanded to 96 bits by appending a jam sequence to the
original fragment.
Jam Signal
If one port detects a carrier, the hub repeats all received data form this port to
another port. If a collision is detected while sending data to a port, the hub
sends the jam signal to all connected ports. If the collision status continues on
only one port even after 96 bits of jam signal have been sent, the jam signal is
sent to ports in the non-collision status.

UTP, Cascade, and Uplink Ports
While the eight UTP ports can be used to directly connect to workstations in a
standalone configuration, Port 8 is equipped with an MDI/MDI-X switch that
conveniently provides the connection (cascade) to other hubs.
In addition, the 10Base-FL(ST/SC) port provides the uplink connection to a
fiber backbone network. See Figure 5. Also, see Chapter 3 “Configurations” for
standalone, cascade and uplink configurations.

MDI/MDI-X Switch
The Media Dependent Interface/Media Dependent Interface Crossover (MDI/
MDI-X) switch is a slide switch that allows you to connect to either another hub
or to a workstation by converting Port 8 to an uplinkable port; thereby allowing
one hub to connect to another hub without requiring special crossover cables.
Figure 6 illustrates this switch; Table 3 defines the switch’s function.

Installation
Before You Begin
Before proceeding with the installation, please read “Electrical Safety and
Installation Requirements” on page iii through xviii
Note
Installation of this product should only be performed by TRAINED
SERVICE PERSONNEL.
Power Requirements
Be sure that the voltage and frequency is either 100-120 or 200-240 VAC and
50 or 60 Hz. Since there is no external power switch, power is applied when the
power cord is connected.
.
Installing the Hub
Making UTP Port Connections
1. Carefully remove the AT-MR840TF hub from its packaging box. Keep the
packing materials for future use.
2. Position the hub in a location with adequate ventilation and a power
source.
3. Attach an AC cord to the hub and make sure that the POWER LED on the
front panel lights.
4. On the hub side, attach your 10Base-T UTP cables (RJ45 connectors) to the
10Base-T ports.
5. On the workstation side, attach the other end of the UTP cable to the
10Base-T network adapter card on the workstation.
11
Page 32
Installation
Note
If you are not using the UPLINK port (Port 8) for cascading to
another hub, you may connect a standard 10Base-T cable to Port 8.
Set the MDI/MDI-X switch to the MDI-X position.
6. Make sure that the LINK OK LEDs light green. If the LINK OK LEDs do
not light, check that the adapter card on the opposite end of the UTP
segment is operational.
Making 10Base-FL Uplink Port Connections
To make a fiber uplink connection to the network/backbone:
1. Connect the 10Base-FL cables (either SC or ST) to their respective fiber
connectors.
2. Make sure that the LINK LED for the fiber uplink port lights green.
Making Cascading Connections
To cascade (connect from one hub to another):
1. From the first hub, connect Port 8 to any of the available UTP ports on the
second hub. Continue this scheme for any additional hubs, always first
going from Port 8 to an unused UTP port.
2. Make sure the MDI/MDI-X switch for Port 8 is set to the MDI position if
you select Ports 1-7 of the second hub.
3. If you cascade two hubs using Port 8, make sure you set the MDI/MDI-X
switch to the MDI-X position on only one of the hubs.
Note
Any two ports can be used to cascade hubs as long as one side is set to
the MDI position while the other side is set to the MDI-X position
using straight-through cable. However, Allied Telesyn recommends
that you use the dedicated MDI/MDI-X port (Port 8) to connect to
available UTP ports (1-7) when cascading hubs.

Verifying Installation
1. Make sure that the LINK OK LED of the first connected 10Base-T port is
lit. A steady green LED indicates continuity.
2. After a successful connection, disconnect the active 10Base-T connector
and connect it to the next successive port. Continue this process until all
10Base-T ports have been validated with good network connections.
3. Establish a connection from a device connected to Port 1 to a device
connected to Port 2.
4. Once the connection between devices attached to Ports 1 and 2 has been
successfully established, remove the RJ45 connector from Port 2 and
connect it to each of the subsequent hub’s 10Base-T ports, 3 through 8, to
verify their functions.
5. If all ports test successfully, install the rest of the 10Base-T RJ45
connections and make sure that the LINK LED for each port lights.
Remember, the 10Base-T device on the opposite end of the UTP cable must
be operational.
Note
The LINK OK LED validates the receive pair only. The opposite end
of the UTP segment is responsible for validating the transmit pair.
13
Page 34
Installation
If the LINK OK LED does not light, there is no signal continuity.
1. Check that the attached Data Terminal Equipment (DTE) is ON.
2. Check that the Link signal has not been disabled at the other network
device.
If these checks do not identify the problem, it may indicate that the hub or
device connected to the port is faulty.
Verifying Collision LED
The COLLISION LED will blink when an SQE or collision occurs. Occasional
collisions are normal in Ethernet networks. A COLLISION LED that remains
on may indicate that a specific port is experiencing excessive traffic problems.
Continuous blinking of the COLLISION LED may also indicate excessive frame
collisions on a segment. This may be caused by an overloaded segment, a faulty
cable or connection.

Figure 8: AT-MR840TF Fiber Backbone Configuration
Overall, in a backbone network configuration, each workgroup has its own local
network and the backbone is used to link the various workgroups through one
or several hubs. The advantages of a backbone network are twofold:
❑ As long as the backbone network is operating correctly, any problem
within a sub-network does not affect other sub-networks.
❑ Since faults are isolated to a single sub-network, they are easier to
locate.
The IEEE 10Base-FL standard extends a fiber segment length to 2 km. This
applies only to configurations in which one 10Base-FL node connects to another
10Base-FL node.
16
Page 37
AT-MR840TF Installation Guide
Cascade Configuration
Port 8, used in conjunction with the MDI/MDI-X switch, is the specified port
that allows you to connect one hub to another (cascade) or to connect to the
backbone using the same medium type. To cascade hubs, you should connect
Port 8 of the first hub to Ports 1-7 of the second hub and continue this scheme
for any additional hubs. The MDI/MDI-X switch for Port 8 of the first hub must
be set to the MDI position.
Figure 9 shows a cascaded topology using four hubs. Its design complies with
the four-repeater rule discussed in the next paragraph.

The Four-Repeater Rule
The IEEE 802.3 standard provides general rules for 10Base-T cable length and
network connections on single segments of cable or on point-to-point links with
media attenuation and signal propagation delays. The basic rule is that, for any
network, the maximum number of repeaters in the data path between any two
nodes cannot exceed four.

Connector Pinouts for UTP and Uplink Port
Table 6 shows the pinouts for straight through cable when connecting a hub to
a NIC. Table 7 shows the pinouts for straight through cable when connecting a
hub to a hub (cascading using Port 8). According to the 10Base-T specification,
pins 1 and 2 on the connector are used for transmitting data; pins 3 and 6 are
used for receiving data. The “+” and “-” signs represent the polarity of the two
wires that make up each wire pair.

AT-MR820TF Hub Installation Guide
Straight-through Cable Wiring
If the twisted-pair link segment is to join two ports on a switch, and only one of
the ports has an internal crossover, the two pairs of wires must be
straight-through, as shown in Table 8.
Table 8: Straight-through Cable RJ45 Pin Assignments
Hub Device
1 (TX+) 1 (TX+)
2 (TX-) 2 (TX-) 3 (RX+) 3 (RX+) 6 (RX-) 6 (RX-)
Crossover Cable Wiring
Two AT-MR840TFs can communicate only if the transmitter on one unit is
connected to the receiver on the other unit. This reversal, or crossover function,
can be implemented either in the wiring or in the device itself (MDI-MDI-X)
switch. When connecting AT-MR840TFs, a crossover must be implemented in
the wiring. Refer to Table 9 for crossover pin assignments.
