8.2.2.1 Connection blade stacking
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.
