3.2 Hub Stack Connection
A hub stack composed of multiple hubs (up to four) cascaded together
as the instruction in section 2.4 can be treated as a single dual-speed hub
which provides up to 64 dual-speed ports.
If interconnection of the 10M network and the 100M network is re-
quired, one and only one KF-16MS is needed to be installed in a hub
stack to bridge the intertraffic between the 10M network and the 100M
network.
A hub stack still complies with IEEE 802.3u Class II specifications.
Only one connection to another Class II hub via UTP cable is allowed
for a hub stack. The following figure illustrates the maximum network
span containing two hub stacks:
Figure 3-6 Connecting Two Hub Stacks
Two hub stacks are interconnected using a UTP cable between two hub
ports. Each hub stack is composed of four hubs. Two end stations are
located 205 meters apart from each other.
