Connecting Power to Model 1004 Repeater
To power ON the Model 1004 Repeater:
1. At Model 1004 Repeater back, locate the Unit power
receptacle and associated fuse.
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 Model 1004
Repeater power receptacle.
4. Plug outlet end (male) of power cord into correct voltage AC
wall socket.
5. At Model 1004 Repeater front, verify that POWER LED is
illuminated.
NOTE: After the power supply adapter is connected to the Model
1004 Repeater and to external power, the green Power LED is
illuminated.
Ensuring Correct Segment Number
Ethernet 802.3 specifications define segment number, as well as cable
characteristics. (A segment is the cable connection between cable
interfaces in an Ethernet LAN.)
When connecting 1004 Repeaters, 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.
