Ethernet™ Pocket Hub™
Connecting Power to 0402 Pocket Hub
To power ON the 0402 Pocket Hub:
1. Locate the power receptacle on the back of the 0402 Pocket
Hub.
2. Connect the 0402 Pocket Hub power connector end of the
power supply adapter to the Pocket Hub.
3. Connect the external power connector end of the power
supply adapter to external AC power.
NOTE: After the power supply adapter is connected to the 0402
Pocket Hub and to external power, the green Power LED is
illuminated.
Ensuring Correct Segmemt Number
Ethernet 802.3 specifications define segment number, as well as cable
characteristics. NOTE: A segment is the cable connection between
cable interfaces in an Ethernet LAN.
Segment Number
When connecting Pocket Hubs, the transmission path between any
two Data Terminating Equipment (DTE) terminals can consist of no
more than five segments.
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
≤
5).
3. To verify that no segment paths contain more than n segments,
assign segment paths and numbers to all other terminals.
