Up to 8 Connection Blades GbE Switch/IBP 36/8+2 can be switched together to 
form a so-called stack. One of the connection blades takes on the role of the 
master. This connection blade is used to administer all modules of the stack. All 
modules of a stack act as one connection blade. In this way, connection blade 
stacking offers a large number of ports with minimum administrative effort.

The connections within a stack are established through the stacking ports of the 
connection blades. The internal stacking ports to the midplane of the BX900 S1 
system unit are each used to connect two connection blades that are installed 
in the same fabric, i.e. in two adjacent slots. Connection blades in different 
fabrics are connected through the external ports using CX4 cables.
