Figure 3-4. A large multi-hub network with 3 hubs, 13 TriStars, and 2
meters.
• TriStar 1 provides power to hubs X & Y. Do not daisy-chain more
than two hubs.
• TriStar 2 provides power to hub Z to avoid overloading TriStar 1
with three hubs.
• Power Out Port A (Link Out) of hub Z is connected to Port 4 on
hub Y so that communication is maintained between all three
hubs.
• TriStars 3 & 9 each power a TriStar Local Meter.
• All TriStars are electrically isolated.
