1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
LANMaster™ T8 8-Port Ethernet™ Repeater Hub. A working
knowledge of local area network (LAN) operations, including
familiarity with communications protocols used on interconnected
LANs, is assumed.
The LANMaster T8
The TRANSITION Networks LANMaster T8 8-Port Ethernet Repeater
Hub is a 10 Mb/s network device that connects 10BASE-T and
10BASE-2 OR 10BASE-5 Ethernet segments into a single Ethernet
network.
Features:
• Eight fixed RJ-45 twisted-pair connectors at front provide
terminal device connections
• Optional RJ-45 uplink port connector at front eliminates need
for crossover cable between hubs
• BNC and AUI connectors at back provide optional connection
to EITHER 10BASE-2 OR 10BASE-5
• LED indicators at front provide continuous LANMaster T8
network traffic data
The sole purpose of this remedy shall be provided the customer with the replacement or
repair of non-conforming goods in the manner described in this Warranty statement. This
exclusive remedy shall not be deemed to have failed of its essential purpose so long as TN is

processing.
• The item(s) may be shipped by the customer or the distributor.
• Transition Networks will repair or replace the unit, at TN’s discretion, and cover the
cost of the return freight to the distributor or to the customer, whichever requested
the RMA number.
If the item(s) was received more than five years ago, or if the item(s) is no longer covered by
warranty for other reasons, then:
• 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.
