Figure 23 and Figure 24 show how stacking cables are connected between PowerConnect B-FCX624 and PowerConnect B-FCX648 devices in a stack. The connection is based on 10 Gbps SFP+ using LC-LC MM Fiber cables. These devices support linear and ring stack topologies with the optional SFP+ modules installed, and can also operate in standalone mode.

NOTE

PowerConnect B-FCX624 and PowerConnect B-FCX648 devices must have a 4-port 10 Gbps SFP+ module (optional) installed to operate in a stack.

Figure 25 shows a stack containing PowerConnect B-FCX624 , PowerConnect B-FCX648 devices and another PowerConnect B-FCX device. Using PowerConnect B-FCX624 and PowerConnect B-FCX648 devices in this type of mixed stack requires your to reconfigure the default stacking ports on the other PowerConnect B-FCX device. For more information, see the FastIron Configuration Guide.

You can form a stack containing up to eight PowerConnect B-FCX624 and PowerConnect B-FCX648 units. To connect switches in a stack, perform the following steps:

1.Plug one end of an LC-LC MM Fiber cable into one of the SFP+ stacking ports of the top unit.

2.Plug the other end of the cable into one of the stacking ports of the next unit.

3.Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting with a stacking port on the top unit and ending at a stacking port on the bottom unit (stacking up to eight units). See Figure 23

4.(Optional) To form a ring stack topology, plug one end of an LC-LC MM Fiber cable into the remaining stacking port on the bottom unit and the other end into the remaining stacking port on the top unit. See Figure 24.
