Interconnecting Your Stack
893-839-C 2-7
To create a cascade of 100-series hubs, follow these steps:
1. Connect one end of the cascade cable to the Cascade Down connector
on the rear panel of the top hub.
2. Connect the other end of the cascade cable to the Cascade Up
connector of the hub immediately below (see F
igure 2-4).
Figure 2-4. Cascade cable connections in a stack of 100-series hubs
3. Tighten the screw locks on the cable connectors to secure the cable to
the hub connectors.
4. Repeat this procedure for the remaining hubs in the stack.
Choosing Segment Assignments
Use the Segment Select switch on the rear panel of the hub to assign the ports
on a 100-series hub to segment 1, 2, or 3 or to isolate (Isol) the hub from all the
segments.
Consider the following issues when choosing segment assignments for hubs in
a stack:
• If the setting of the switch is changed, the new setting takes effect
immediately.
• If network management software is used to override the switch, the switch
setting may not match the actual segment setting. The actual segment
setting is always correctly shown by the LEDs, as shown in F
igure 2-5.
