8-Port Ethernet Hub w/SIC Slot
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 Hub w/SIC Slot. A working
knowledge of local area network (LAN) operations, including
familiarity with communications protocols used on interconnected
LANs, is assumed.
The LANMaster T8 Hub w/SIC Slot
The LANMaster T8 8-Port Ethernet Hub w/SIC Slot (E-TBT-HB-
0802), is a stand-alone, fully functional Ethernet repeater.
LANMaster T8 8-Port Ethernet Hub w/SIC Slot Features
• Media Dependent Interface (MDI) switch eliminates need
for RJ-45 crossover cable connection between LANMaster
T8 devices.
• Comes with internal power supply.
• Complies with Ethernet 802.3.
• Slide-In Card (SIC) slots for optional installation of
additional media connections.

Maximum segment length depends on the cable characteristics
††††
A network of four repeaters and five segments, can have up to 3
coax segments and 2 required link segments. The maximum
length of a FOIRL link segment must not exceed 500 meters. If
your network has three repeaters and four segments, the
maximum length of a FOIRL link segment must not exceed 1000
meters.
