Overview
CentreCOM AT-810SL Multiport Transceiver Fanout
AT-810SL 8 Port
Fanout, Slim-line
Chassis
The CentreCOM Multiport Transceiver Fanouts are part of a family of
multiport transceivers for use with Ethernet Local Area Networks (LANs).
These units can provide network managers with either small standalone
networks or they can act as a concentrator, grouping several devices onto a
single tap on an Ethernet network.
The CentreCOM Multiport Transceiver Fanouts connect up to 8 Data
Terminal Equipment (DTE) workstations, using standard Attachment Unit
Interface (AUI) “Drop” cables in one of 3 switch-selectable configurations.
When “Remote” operation is selected, the unit can attach to an existing
transceiver using an AUI cable up to 50 meters (164 ft.) in length. In “Local”
operation, the network manager has a choice between operation with or
without Signal Quality Error (SQE)/Heartbeat Test. With the flip of a switch,
the network manager can choose to support or not support SQE Test, or
segment the attached nodes from the main network while still allowing local
communication between workstations.
The CentreCOM Multiport Transceiver Fanout interface is compliant with
the IEEE 802.3 specification and compatible with Ethernet Version 1.0 and
2.0.
When used in Remote Mode, the electrical characteristics of the transceiver
are passed transparently through these multiport transceiver fanouts to the
attached nodes as if each unit was attached with its own transceiver. When in
Remote Mode, SQE should be OFF.
Up to 64 stations can be cascaded together through the AT-810SL. This
permits the workstations to be up to 150 meters (492 ft.) from the backbone
cable and up to 200 meters (656 ft.) apart. By cascading the CentreCOM
Multiport Transceiver Fanouts, over a thousand nodes can be attached to a
single backbone cable without requiring repeaters or additional
internetworking devices.

Overview
2
The AT-810SL has front panel status and diagnostic indicators that provide
“On Line” and “Transmit” status for each port. Figure 1 shows the front
panel. Packet “Receive” and “Collision” indicators are available for the
Transceiver Ports as well as the Station Port. The front panel “System
Power” LED indicates when power is applied to the AT-810SL and the
“Station Power” LED indicates when power is applied to any of the
Transceiver Ports. On the back of the AT-810SL are redundant LEDs
indicating the application of “Station Power” for each Transceiver Port, and
one redundant LED indicating “System Power.”

Installation
Requirements
Before installing AT-810SL Multiport Transceiver Fanouts, read the
electrical safety and installation requirements starting on page i.
Before installing the AT-810SL Multiport Transceiver Fanout, ensure that
the following requirements are met:
❑ The network cabling is properly configured.
❑ Power connections are made at the back panel. The AT-810SL
repeater has a universal power supply that will accept either 110 or
220 VAC at 50-60 Hz.
❑ The appropriate IEEE 802.3 AUI standard transceiver cables are
available.
❑ To prevent equipment damage from overheated components,
adequate air flow must be maintained. Before turning on the power,
verifythatboththeairintakeventsoneachsideofthechassisarefree
of obstructions.
❑ For Remote Mode operation, a CentreCOM 100, 200, 150, 250, 270, or
470 Series external transceiver or other IEEE 802.3 Media
Attachment Unit (MAU) may be required. Contact your supplier for
the appropriate model number.
Procedure
IEEE 802.3 10BASE5 (IEC/ISO 8802-3) conventions and standards place
certain limitations on network configurations. Careful planning before
tapping onto the network will help avoid unnecessary problems. The most
important consideration is the transceiver cable length. When operating in
Remote Mode, please ensure that the AT-810SL is within 50 meters (164 ft.)
of the MAU. In either Local or Remote Mode, DTEs must also be located
within 50 meters (164 ft.) of the AT-810SL.

Installation
4
Once all the cables have been laid and the AT-810SL is placed in the location
of your choice, you are ready to begin the actual connections. (Except for
monitoring the LEDs, there is no benefit in being able to physically see the
AT-810SL during routine operation; the unit may therefore be installed in any
location with adequate ventilation, temperature control and power
connections.)
Power
The CentreCOM AT-810SL Multiport Transceiver Fanout is designed for
desktop or rackmount installation with optional Rack Mount Kits AT-RKMT-
2 and AT-RKMT-3.
AT-810SL requires a 100-240 VAC power source with a line frequency range
from 50 Hz-60 Hz.
The AT-810SL is equipped with an IEC-320/CEE-22 standard power input
connector on its back panel. One end of the power cord should have a
receptacle to fit this type of connector. The other end should be fitted with the
standard power cord plug for the country in which the unit will be operated.
No power cord is provided for European style AC outlets. Obtain the
appropriate cord from your equipment vendor.

Operation
Station Port Configuration
The AT-810SL is designed to require a minimum of operator attention during
routine operation. The station port configuration allows access, via an AUI
cable and transceiver, to an Ethernet coaxial cable or fiber optic cable. This
port is only used when the AT-810SL is set in Remote Mode. Once the unit
has been installed and set for your particular configuration, it will be
transparent to the users and to the network.
Two switches are provided on the back panel, allowing selection of Local or
Remote Mode and SQE Test ON or OFF. Local Mode allows operation of the
equipment linked to the AT-810SL as a standalone “mini-network” giving the
option to have the SQE Test ON or OFF, depending on the application. In the
Local Mode the Station Port is disconnected from the Transceiver Ports. In
the Remote Mode (i.e., access to an external transceiver attached to an
Ethernet coaxial or fiber optic cable), the AT-810SL is a “pass-through” unit
with the SQE Test provided by the transceiver connected to the Ethernet
cable. Figure 2 shows the Station Port configuration.
When used in Remote Mode, the SQE Test switch should be OFF.

LED Status Indicators
The AT-810SL has many LEDs to aid in installation and troubleshooting
should any problems occur. They also serve to verify correct transceiver
operation at a glance. Below is a description of their location, grouping and
functionality. Refer to Figure 3 for location of the System Power and Station
Power.
Front Panel System Power —When lit, this LED indicates correct AC voltage applied
and internal power supply is operational.
Station Power — When lit, this LED indicates that power (+12 volts) is
applied to Pin-13 of the Station Ports DB15 connector by the MAU backbone
transceiver via the AUI cable.
Refer to Figure 4 for location of Station Port indicators.
This group of LEDs is associated only with the Station Port and as such are
only active when the AT-810SL is configured for Remote operation via the
two-position Station Port configuration switch.
On Line —When lit, this LED indicates that the Mode Selection switch is in
the Remote position. This is for configuration status only.
Transmit —When lit, this LED indicates a packet is being received into any
of the eight Transceiver Ports and transmitted out through the Station Port.
Receive — When lit, this LED indicates a packet is being received into the
Station Port and is being routed to the eight Transceiver Ports.
Collision —When lit, this LED indicates a Collision or SQE occurrence on
the segment to which the Station Port is connected.

Refer to Figure 5 for the location of the Transceiver Ports.
On Line —When lit, these LEDs indicate that the corresponding
Transceivers Port is connected through an AUI cable to a DTE device, and
that the DTE is powered-up and On Line.
Transmit —When lit, these LEDs indicate that the corresponding
Transceivers Port is receiving a packet and transmitting it to the other seven
Transceiver Ports. If in Remote Mode, this packet will also be sent out
through the Station Port.
Receive —When lit, this LED indicates that each of the Transceiver Ports is
presenting a packet to its associated DTE. Only one LED is required to
represent this function, as all of the Transceiver Ports are effectively parallel
for this function.
Collision —When lit, this LED indicates that a Collision or SQE has
occurred on or between one or more of the Transceiver Ports. This is not a
latched condition, so if this LED is steadily lit, a hard failure or a
configuration problem with one of the DTE’s is occurring, or an inordinate
number of Collisions are occurring, indicating overload and warranting
further attention. Collisions between the Transceiver Ports themselves will
not be propagated through to the Station Port, and thus will not impede
network activity on the Remote Segment.

Refer to Figure 6 for the location of the Status Indicators.
On Line(s) —Each Transceiver Port has an associated On Line LED. When
lit, these LEDs indicate that the DTE, connected to the related port through
the AUI cable, has power applied to it. These will be lit/unlit regardless of the
AT-810SL’s operational status and are provided so a DTE’s “in use” status can
be ascertained before disconnection of its cable.
System Power —When lit, this LED indicates AC power is correctly
applied and the internal power supply is operational. This indicator is
redundant with the System Power LED on the front panel, it is provided for
ease of viewing from the back in rack mount applications.
