Considerations
Limitations
There is no limit to cascading the number of hubs within a network as long as
the following guidelines are followed:
Note:
Refer to the hub manufacturer’s requirements for cascading, the
following are just general guidelines.
•
The length of the cable affects the number of allowable ports.
•
The hub adds length to the cabling in the network.
•
Use ports 1 and 4 to cascade to other hubs. This increases the potential of
dual port devices and redundant paths.
•
Do not exceed the maximum number of hubs per cascade link.
The maximum number of hubs before retiming is six (6) with short cables,
two (2) with maximum length cascade cables.
•
Configure the loop so the devices are properly positioned in relation to the
hub.
is an example of cascading hubs.
