4. If installing a single switch only, proceed to “Powering on the system” on page 16.
5. If installing multiple switches, mount them in the rack, one below the other, in any order.
Connecting devices in a stack
B-FCX624S and B-FCX648S devices
Figure 7 on page 14 shows how the stack cables are connected between switches in a stack. The connection is
based on 10G/16G Gigabit Ethernet using CX4 cables. B-FCX devices support linear and ring stack topologies, and
can also operate as standalone devices.
In a linear stack topology there is a single stack cable connection between each switch that carries two-way
communications across the stack. In ring stack topology, 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 7 on page 14 illustrates a ring-topology stacking
configuration.
You can form a stack containing up to eight B-FCX units. To connect switches in a stack, perform the following steps:
