Connection blade stacking
Up to 4 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 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. 
Figure 27: CX4 cable
The stacking connections within a stack must form a circuit. Connection blade 
stacks can be formed within a system unit, across several system units of a rack 
or across several system units in different racks.
Further information
You determine which connection blade takes on the master role through the 
sequence and the intervals at which the connection blades are booted and 
connected with each other. For more detailed information and additional 
possible configurations, see the manuals "PRIMERGY BX900 Blade Server 
Systems – Ethernet Connection Blade Module IBP Version – User’s Guide",
