Connecting Switches in a Stack
Figure 3-6 shows how the stack cables are connected between switches in a
stack. The connection is an Ethernet connection using Category 5 cables.
The switch supports a line- and ring-topology stacking configuration, or can
be used stand alone.
In line-topology stacking there is a single stack cable connection between
each switch that carries two-way communications across the stack. In
ring-topology stacking, an extra cable is connected between the top and
bottom switches forming a “ring” or “closed-loop.” The closed-loop cable
provides a redundant path for the stack link, so if one link fails, stack
communications can be maintained. Figure 3-6 illustrates a ring-topology
stacking configuration.
To connect up to eight switches in a stack, perform the following steps:
1. Enable the stacking ports on each unit (i.e., leave the Stack button out).
Note: Pressing the Stack button during normal operation will cause the
system to reboot.
2. Plug one end of a stack cable (ordered separately) into the “Down” port
(see Figure 3-6, Port 27) of the top unit.
3. Plug the other end of the stack cable into the “Up” port (see Figure 3-6,
port 28) of the next unit.
4. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain
starting at the “Down” port on the top unit and ending at the “Up” port
on the bottom unit (stacking up to 8 units).
