• Call the distributor or contact TN.
• Request a Material Repair Authorization number (MRA).
• Ship the item(s), prepaid, in the original packaging to Transition Networks at the
above address.
• Include the MRA number on the outside of the carton add/or on the Packing List.
• Include a copy of the MRA form.
• Include a copy of the original invoice or packing list (if possible) to expedite processing.
• Only the customer (end-user) may send the items(s) to TN.
• TN will contact the customer after the item(s) have been received, inspected, and a
cost estimate of the repair determined.
• The repair charges may be billed, with customer’s approval, though the distributor, or
on a prepaid or C.O.D. basis directly to the customer. The charges will include the
cost of shipping.
The return authorization numbers are valid only for 90 days from the date issued.

Connectors and Indicators
CONNECTORS
Eight (8) straight-through RJ-45 connectors, labeled 1X-8X, and one
(1) crossover RJ-45 connector, labeled 8I, are located on the front of
the LANMaster T8-FL.
One (1) TX and one (1) RX fiber ST connector and one (1) AC power
supply adapter connector are located at the LANMaster T8-FL back.
LED INDICATORS
Steady green Link/RX LEDs indicate (for each port 1-8) the integrity
of the network link at the RJ-45 connector. Blinking green Link/RX
LEDs indicate (for each port) reception of valid data.
Steady green FL LED indicates the integrity of the network link at the
fiber receive (RX) connector. Blinking green FL LED indicates
reception of valid data.
Blinking green TX LED
indicates transmission of
valid data at the fiber transmit
(TX) connector.
Steady green Power LED
indicates connection of the
LANMaster T8-FL to external AC power.
Blinking yellow Collision LED indicate network collisions.
5. MAINTENANCE
WARNING: DO NOT, UNDER ANY CIRCUMSTANCES, open
and attempt to repair the LANMaster T8-FL. Failure to observe
this warning could result in personal injury or death from
electrical shock.
NOTE: Failure to observe the above warning will immediately void the
warranty.
Fault Isolation
If two network devices fail to communicate through the LANMaster T8FL, consider the following:
• Are the LEDs described in the previous section functioning
properly?
• Do network devices have Link Integrity enabled?
• Do network devices communicate when the LANMaster T8-FL
is not installed between them?
• Is flat or “silver satin” wire used in site internal wiring?
• Are internal wiring patch cords, punch down blocks, and wall
jacks properly pinned or configured?
• Are network interface cards properly configured?
• Are network cables and connectors properly installed?
Technical Support Contact
For assistance in fault isolation and in maintaining the LANMaster T8FL, contact:
Technical Support (800) 260-1312
or your local distributor.

Powering the LANMaster T8-FL
To power ON the LANMaster T8-FL:
1. Verify that the LANMaster T8-FL power supply adapter is the
correct power supply adapter for the site installation.
2. At LANMaster T8-FL back, locate the power receptacle.
3. Connect the LANMaster T8-FL power connector end of the
power supply adapter to the LANMaster T8-FL power
receptacle.
4. Plug external power connector end (male) of the power
supply adapter into correct voltage AC wall socket.
5. At LANMaster T8-FL front, verify that Power LED is
illuminated.
3. INSTALLATION
To install the LANMaster T8-FL:
• Unpack the LANMaster T8-FL
• Install LANMaster T8-FL at site
• Install Network Cable
• Power the LANMaster T8-FL.
Direction is provided in the pages that follow.
Unpacking the LANMaster T8-FL
The LANMaster T8-FL packing contents should include the following:
Item Part Number
LANMaster T8-FL Hub E-TBT-HB-0810
(includes mounting brackets and screws)
Power Supply Adapter 3542, 3543, 3544, or 3545
(depending upon power configuration
in country where installed)

Installing Network Cable
10BASE-T Cable Connection Requirements
STRAIGHT-THROUGH/CROSSOVER CABLE/CONNECTOR
NOTE: The 10BASE-T cable and RJ-45 jacks for hub-to-terminal device
connections must be configured as straight-through. The 10BASE-T
cable and RJ-45 jacks for hub-to-hub connections must be configured
as crossover. The “8I” port provided on the LANMaster T8-FL front
changes a physical straight-through configuration cable to a logical
crossover configuration cable for hub-to-hub connections.
Ensure that all 10BASE-T cable to be installed is configured as straightthrough:
FIVE-SEGMENT RULE
10BASE-T cable segments can be installed as a single Ethernet collision
domain if the cable segments are connected using repeaters. (A
segment is the independent network cable connection between
repeaters or between repeaters and network devices.)
When connecting LANMaster T8-FL repeater hubs, the transmission
path between any two network devices can consist of no more than
five segments.

To verify the network configuration by assigning segment numbers to
cable connections:
1. Determine the two terminal devices in the network which are
separated by the greatest number of segments.
2. Assign a segment path between the terminal devices by
labeling the cable connected to one of the terminal devices
“segment 1” and the segment connected to the other terminal
device “segment n” (n = total number of segments ≤ 5).
3. To verify that no segment paths contain more than n segments,
assign segment paths and numbers to all other terminal
devices.
