8-Port Ethernet Hub w/SIC Slot
Ensuring Compliance with 5-Segment Rule
To conform to the Ethernet 802.3 specification, when connecting
LANMaster T8 Hubs, the transmission path between any two Data
Terminating Equipment (DTE) devices can consist of no more than
five segments. NOTE: A segment is the cable connection between
cable interfaces in an Ethernet LAN.
To assign segment numbers to cable connections:
1. Determine the two terminals in the network which are
separated by the greatest number of segments.
2. Assign a segment path between the terminals by labeling the
cable connected to one of the terminals “segment 1” and the
segment connected to the other terminal “segment n” (n =
total number of segments and must be 5 or fewer).
3. To verify that no segment paths contain more than n
segments, assign segment paths and numbers to all other
terminals.

Powering the LANMaster T8
To power ON the LANMaster T8:
1. At LANMaster T8 back, locate the power receptacle and
associated fuse.
NOTE: Fuse must be installed at correct setting for power source voltage
before connecting to AC outlet.
2. Verify that fuse is installed at correct setting for power source
voltage.
NOTE: The installed fuse rating is indicated by the reading at lower right
corner of fuse holder.
If not installed at correct setting for power source voltage:
• Carefully open fuse receptacle, using a small flat blade
screwdriver.
• Rotate fuse holder 180° to the correct rating orientation.
• Install fuse holder in correct rating orientation.
• Close fuse receptacle.
3. Plug unit end (female) of power cord into LANMaster T8 power
receptacle.
4. Plug outlet end (male) of power cord into correct voltage AC
wall socket.
5. At LANMaster T8 front, verify that POWER LED is illuminated.
