Note
If more hub ports are required, they can be added by connecting more than
one hub. There are two possible connection methods for hubs: Cascade and
stacked.
Cascade Connections
It is very difficult to distinguish cross cables and straight cables by appear-
ance. Incorrect cables will cause communications to fail. We recommend
using cascade connections with straight cables whenever possible.
• Do not lay the twisted-pair cable near devices that generate noise.
• Do not lay the twisted-pair cable in locations subject to high temperatures
