Connecting Hubs Using 10BASE-2 (Coax)
When using 10BASE-2 (Coax) cable, it is important
that both ends of the segment are properly
terminated with 50 Ohm terminators ( end pieces ) .
Only use 50 Ohm 10BASE-2 (Coax) cables and use a
'Y' piece for each hub. You can use 'T' pieces but 'Y'
pieces provide adequate clearance of the other ports.
Connect a 10BASE-2 'Y' piece to each of your hubs.
Daisy-chain each 'Y' piece with 10BASE-2 (Coax)
cable to form a single segment, as shown in
Figure 2-4 . Remember to terminate the two free ends
of the segment by fit ting t erminators (end pieces).
To disconnect a 10BASE-2 (Coax) cable, twist each
connector counter-clockwise to unlock it, and
remove it.
