Powering the LANMaster T8

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.

SIC Connection

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:

110-120 Orientation

220-240 Orientation

240-220	120-110
110-120	220-240

Fuse Holder

•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.
