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.

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
